Consider a piconet as shown in Figure-2a, where node-A is the master denoted Hello, I have had luck in Keil making two NRF52 connect with NUS, central and peripheral. Two or more inter-connected piconets form a scatternet. One piconet has a total of three slaves and the other has a total of 7 (the maximum) slaves. CLKN: Native Clock of a Device CLK: Piconet Clock Bluetooth Technology 32 Phase of a Hop Sequence •The phase (channel number) of a hop sequence at a particular time depends on the A piconet is the type of connection that is formed between two or more Bluetooth-enabled devices, one device takes the role of 'master', and all other devices assume a 'slave' role for How does it work? Let’s take our beloved Bluetooth as an example to understand. The master in the old piconet broadcasts the role switchover to all the slaves, and all the slaves in the old piconet initiates a connection to the new master by disconnecting the old piconet. ) For example, you can have a desktop PC, a laptop, a smartphone,  Energy, Piconet, Scatternet, Mesh, Single hop, Multi hop, Single mode, Dual mode . The figure shows the simplest example of a piconet. An example of the TDD scheme in a Bluetooth piconet Time (slots) Slave n Slave 2 Slave 1 Master The master schedules the traffic within a piconet according to an intra-piconet scheduling algorithm. So only option for a One Master - multiple slaves is to maintain a Time multiplexed connection strategy. with regard to cable cross sections, fuses, PE). This very small network is A piconet is an ad hoc network that links a wireless user group of devices using Bluetooth technology protocols. Note that you may not end up with a description for each element of PICO. Piconet is the basic topology used in the IEEE802. Bluetooth Low Energy (BLE) is an emerging low-power wireless technology developed for short-range control and monitoring applications that is expected to be incorporated into billions of devices in the next few years. from one piconet to another (we refer to such a unit as a bridge). Y. The topology of this network is known to all devices. There will be maximum 7 active slaves in the piconet. Some examples of piconets include 1) a cell phone and a  package com. Please check out the code i'm working on: Can anyone please suggest a proper method to implement it Example 2. Each piconet has a different physical channel (that is a For example if V1 master has V2, V3, V4 slave vertex, V1 have to know each of these three node’s distance The basic piconet physical channel is characterized by a pseudo-random hopping through all 79 RF channels. Bluetooth. Hence, a typical classroom may easily have a large number (e. Bluetooth operates in the The specification limits the number of Slaves in a Piconet to seven, however larger networks can be set up using many Piconets to communicate with one another, and this is known as a Scatternet. • All timing signals of a piconet are derived from the master clock. Intuitively,this is an undesirableeffect, evenif its magnitudede-pends on the number of nodes involved in the affected piconet. For example, a bridge can be a master in one piconet and a slave in another piconet. of each piconet with which it is currently communicating and sets the hopping pattern of the piconet in which it is the master. It is a low–cost  (This labyrinth of connected devices is called a piconet; you can have up to two piconets. In the figure, a cell phone is downloading the address book and telephone number information to the user’s laptop. Larry Feldman and Greg Witte are Guest Researchers from G2, Inc. The National Telecommunications Act opened new public access to the ultra high frequency (UHF) and very high frequency (VHF) bands. A Free & Open Forum For Electronics Enthusiasts & Professionals . - jonnysgomes/piconet It is possible for a device to take part in two different piconets by swapping between two different frequency-hopping sequences. The connection between a cell phone (master) and a smartwatch (slave) is an example of a simple Bluetooth piconet. Each piconet can have only one Master, one to seven active Slaves, and 0-255 Parked Slaves. (HC 05 Bluetooth module Arduino code is also given in the content) it can associate to an existing piconet. A scatternet is a number of interconnected piconets that supports communication between more than 8 devices. GET APP . Simply, my computer will have a bluetooth module, and there will be an another bluetooth module (free module), and there will be also a PDA which has a bluetooth module. The devices in a Bluetooth piconet define metrics on each channel of 1 MHz. Fig. Piconet • Piconet is a Bluetooth network that consists of one primary (master) node and seven active secondary (slave) nodes. concept of a piconet, which is BT's fundamental. , those that use the lowest connInterval values) yield a limited piconet size. In a Scatternet a device can be a Master in one Piconet and a Slave in another, or a Slave in both, but never a Master of more than one Piconet. InputStream;. It is impossible for a device to be master in two piconets at the same time. 1. 15. CS 164 Programming Project – Winter 2005 I. com with free online thesaurus, related words, and antonyms. However, a unit cannot be a master  Aug 29, 2012 Currently, a BLE device can only belong to one piconet. When Bluetooth devices connect to each other (for example, your phone and your wireless speaker), it’s known as a master-slave relationship ESP32: Internal Details and Pinout: In this article, we will talk about the internal details and the pinning of ESP32. e. From now, the term piconet is used instead of IEEE802. Example of the IEEE 802. • Bluetooth is, with the infrared, one of the major wireless technologies developed to achieve WPAN. A general structure of packets maintained by Bluetooth Baseband is shown in -a. Bluetooth programming in C with BlueZ There are reasons to prefer developing Bluetooth applications in C instead of in a high level language such as Python. It's a secure protocol, and it's perfect for short-range, low-power, low-cost, wireless transmissions between electronic devices. ).

The term “piconet” applies to both ad hoc and infrastructure Bluetooth networks. It can be a slave in one piconet and master in another. We verified with Stonestreet One this is definitely possible, but we are having a hard tome putting it together from scratch given we are on a time crunch. The Peripherals are also using NUS service to send data with(ble_nus_string_send) to Central. 1b shows an example in which all nodes are part of a single piconet 1. For example, headphones may initiate a call from a smart phone. When a piconet is formed, one device acts as the master while the others act as slaves for the duration of the piconet connection. For example, Cordeiro [3] developed a model implementing the basic  Bluetooth is an example of personal area network. For example, in a piconet consider the action of a transmitting slave when the available bandwidth is reduced. When a network is established, one device takes the role of the master while all the other devices act as slaves. The 'Central' application was built on ble_app_uart_c example, which is now successfully connecting up to 7 peripherals. Cada dispositivo da rede estabelece uma conexão com o outro. By "connect" I'll assume you mean "at the same time". Note that packet 3 will interfere. One interconnectivity model is a piconet, which is composed of two or more Bluetooth devices within close physical proximity, operating on the same channel, and using the same frequency hopping sequence, as in the example of the Class 3 devices above. 11b wireless 1 Industrial, •Bluetooth devices can participate in multiple piconets simultaneously creating a topology called Scatternet. Abstract.

Does anyone know if there is some synchronization technique in receiving data from the master? Is it possible using HC05 modules? Thanks a lot in advance in the piconet. Bluetooth is based on what’s officially known as the Frequency-Hopping Spread Spectrum, which takes advantage of a master-slave configuration between devices in a piconet (basically a local network). For example, a server that runs a 'temperature sensor' service may account with a  Piconet = set of Bluetooth nodes synchronized to a master node Communication between piconets = devices jumping back and forth . But i didn't get proper output. Scatternets can be formed when a member of one piconet (either the master or one of the slaves) elects to participate as a slave in a second, separate piconet. Download scientific diagram | Example of Bluetooth piconet topology [3]. Each slave should send a data (for example a number) to the master synchronously and then the master will have to process such data. The slaves are units within the piconet that are synchronized to the master via its lock and hopping sequences. The 'Central' application was built on ble_app_uart_c example, which is now successfully connecting up to 7  We will refer to such a unit as a bridge. A master can have up to 7 slaves, which is why your computer can be connected via Bluetooth to multiple devices at the same time (for example, a wireless keyboard, mouse, printer, speaker, etc. On the right, a device is a slave to two A piconet is a network that is created using a wireless Bluetooth connection. 83. EEVblog Electronics Community Forum. Bluetooth also supports connections between piconets: When a master on one piconet becomes a slave on another, it provides a bridge between them. A piconet is sometimes called a PAN. Miˇsi´c The Hong Kong University of Science and Technology Clear Water Bay, Kowloon Hong Kong SAR, China. Then, I will positioned my computer to my table, free module will be positioned 10 metres away and PDA will be set to Bluetooth Personal Area Network Technology . 1-4 Bluetooth Technology: Beginner’s Guide Bluetooth Profiles What is a Bluetooth profile? A specification for a type of Bluetooth device defined by Bluetooth SIG Defines how the device uses the Bluetooth protocol- which parts of the stack are used? This project covers what bluetooth low energy is and how to use it with the Arduino 101. There can be up to seven active slave devices. Both are usually applied to Bluetooth devices. malfunction (for example, by means of separate limit switches, mechanical interlocks etc. This model includes CVSD speech coding,  Apr 1, 2017 It has two main modes of operation: piconet following and survey mode. Human Interface Device (HID) HID is the go-to profile for Bluetooth-enabled user-input devices like mice, keyboards, and joysticks. When devices are connected together via Bluetooth, it’s called a “piconet”. The presence of bridges in different piconets has to be controlled by an inter-piconet scheduling algorithm. If so then I will buy 5 nos of CYW920735Q60EVB-01 Evaluation Kit. computer. The performance of a single Bluetooth piconet is analyzed using the theory of M/G/1 queues with vacations.

Piconet Communications. Moreover scatternet and piconet are ad hoc computer networks. I designed server and client using following example, please check this link. A master device in a piconet transmits on even numbered slots and the slaves may transmit on odd numbered slots. Piconet has a maximum network range of 7 devices while scatternet has a range of more than 8 devices. In our example, the connection table determines that there are two master candidates for the piconet, namely BD-3 and BD-4. The piconet, which is the basic BluetoothR networking unit, utilizes a Master/Slave (MS) con guration that permits only a single master and up to seven active slave devices. This structure limitation prevents BluetoothR devices from directly participating in larger Mobile Ad Hoc Networks (MANETs) and Wireless Personal Area Networks (WPANs). Bluetooth devices, a piconet is formed n Always 1 master and up to 7 active slaves n Any Bluetooth device can be either a master or a slave n Can be a master of one piconet and a slave of another piconet at the same time (scatternet) n All devices have the same timing and frequency hopping sequence The most energy-demanding configurations (i. A piconet consists of two or more devices occupying the same physical channel (synchronized to a common clock and hopping sequence). In this paper, we shall focus on two well-known intra-piconet scheduling regimes, which were analyzed in [19]: Scatternet is formed two or more piconets form a network, it actually acts as a bridge between multiple piconets. A typical example of this can be portrayed as a classroom where each student operates his/her own Bluetooth piconet to transfer or synchronise files. Internet bridge Connect to the Internet no matter where you are, using a laptop and a mobile phone. Starting from the knowledge of the end–to–end traffic matrix, we address stability I'm making a sort of joy-con setup, where there's 2 controllers and 1 receiver. Meaning of Piconet: a small computer network using Bluetooth protocols This definition of the word Piconet is from the Wiktionary dictionary, where you can also find the etimology, other senses, synonyms, antonyms and examples. A master in one piconet can be a slave in another, if the other piconet's master pages it (i. The frequency hopping channel is divided into time slots. 4-GHz Industrial, Scientific and Medi- fully and partially loaded piconets. Multiple piconets which are interconnected by bridges are called scatternet. 2 Piconets with “unsynchronized” time slots Some of these components do not always apply. The basic hopping I need to create PICONET with 4 slave and 1 master. 5 ms, the number of slaves per master is between 2 and 11, depending on the scheme to co-exist in a physical environment. Example: Often we start with a vague question such as, "How effective is CPR, really?" But, what do we mean by CPR? And how do we define effective? PICO is a technique to help us - or force us - to answer these questions. Aghvami Abstract— Multiple Bluetooth piconets operating in the the problem by presenting simulation results considering globally available 2. After establishing the piconet the slave clock is synchronized to the master clock by adding an offset to the slave’s native clock. There are two types of network topologies in bluetooth viz. Each slave has a single bluetooth transceiver so that it can only transmit once per bluetooth slot. There are two problems. edu, rrao@ucsd. delivered to the SINK of the piconet. Example network. Capturing Bluetooth Traffic, the Right Way . (b) To form . All work relating to transport, installation, commissioning and PDF | In this paper we investigate the impact of the master choice on the performance of a Bluetooth piconet.

The LED blink example works to talk to multiple BT chips at the same time, but I want the same thing just using NUS for basic serial data transmission. You have been treating a 54-year old woman for many years and despite the excellence of your fixed partial denture restorations, the intense routine maintenance by her periodontist, and good homecare, she has been experiencing a continued deterioration of her periodontal tissues. A. Piconets This Arduino Uno Bluetooth module tutorial discusses what is Bluetooth, how does it work, the Arduino Bluetooth HC 05 code , How to connect Bluetooth module, and how to use the Bluetooth module with Arduino by the help of an Arduino sketch. example. The access code identifies packets from different piconets, and is derived from the master (BD_ADD). • Piconet’s range of connecting devices is limited, so scatternet are formed. Other important issues to be considered in a Bluetooth scatternet formation Synonyms for piconet at YourDictionary. Each time slot is  This page compares piconet vs scatternet concept used in bluetooth and mentions difference between piconet and scatternet bluetooth network types. In this demonstration, a software test bed will be used to show that the collision resolution technique enables robust coexistence of multiple Bluetooth piconets. The following example shows a situation where Bluetooth is working in close proximity to a source of interference. The Bluetooth topology can best be described as a multiple-piconet structure. When Bluetooth devices connect to each other (for example, your phone and your Not only can a device be a master in one piconet and a slave in a different   A group of devices synchronized in this fashion forms a piconet, which may contain one master and up to seven active slaves, with additional slaves that are not  Apr 7, 2008 or microwave oven for example. The piconet is structured in a hierarchical arrangement which is composed of one master and one or more slaves. Figure 2 shows two different examples of scatternets. DataInputStream;. Adding your piconet to an existing Shorewall configuration is by far the easiest method. The systems and techniques involve wireless communications wherein a process, module or communications terminal is capable of engaging in intra-piconet communications. Advanced communication techniques such as frequency hopping, whitening, and encryption are all characteristics that make this ever-evolving technology “sniffer unfriendly”. At last, the manner a given device can get out a piconet is also presented. A specific frequency-hopping sequence is used by all devices within each piconet. Figure1below provides an illustration of a sample Bluetooth piconet. Good examples of this kind of applications are mobile terminal headsets and dial-up networking between  "piconet" is used to refer to the network formed by one device and all devices found within its range. Figure 3. Piconet [5] is another example of compact node architecture. As a direct consequence, wireless local area networking is becoming the communications standard for small and mobile corporations. It depends on the capabilities of both devices and the type of service they can provide. 1 Example of inter-piconet interference. Since BD-4 has the highest Bluetooth address, it will become the master while BD-3 will serve as a backup master. As an example, consider two Bluetooth piconets. , 1 is shared, 0 and. It however cannot be a master in more than once piconet. Everything is woking fine but the main issue I have with just plain BLE is that you're still restricted to 1:1 pairing - if in the case that you need to communicate to more than 1 device, everything sort of falls apart. (Bluetooth doesn’t use a CSMA/CD scheme which you may be familiar with from ethernet studies. Piconet 5 in piconet A, for example to establish wireless link 2-1 with slave/advertiser 5-1 as indicated by reference numeral 15, and then may perform two-way wireless data communication with a slave/advertiser, for example with slave/advertiser 5-2 as indicated by reference numeral 17. Introduction The IEEE 802. 3 standard[1] defines the data link layer functions for wireless personal area networks (WPANs), called piconets. piconet stations are IP 67 rated and designed to be mounted directly on the machine with no need for a separate enclosure. When Bluetooth devices connect to each other, they form a piconet, a dynamically created network that comprises a master device and up to seven slave devices. If the address of a server is hard-coded into a client program, for example, then choosing a device is no choice at all. In the Bluetooth specifications [5], the capacity allocation by the master to each link in its piconet is left open. An Analysis of Bluetooth Scatternet Topologies Rohit Kapoor, M. So, this is a doubly sub-stochastic matrix all of whose entries are multiples of 1/7. I will show you how to correctly identify the pins by looking at the datasheet, how to identify which of the pins work as an OUTPUT / INPUT, how to have an overview In some implementations, the LRUs of the system 100 can be Bluetooth-enabled, meaning that the LRUs include Bluetooth communication devices that can be configured to communicate with other Bluetooth-enabled devices within a PAN or PICONET. Guide to locating health evidence. Some examples of piconets include 1) a cell phone and a computer, 2) a laptop and a Bluetooth-enabled digital camera, or 3) several PDAs that are connected to each other. Because Bluetooth is designed to work in a number of different circumstances, it can be either half-duplex or full-duplex. Wireless Networking Given the hardware limitations and physical environment in which the nodes must operate, along with applications level requirements the algorithms and protocols must be designed to provide a For example, let L=M and consider the MxM matrix whose entry in the i th column j th row is the number of layer-one slots of the i th piconet that are dedicated to the j th shared slave of the scatternet. Start studying Chapter 9 - Wireless Network Security. The devices in the testbed are Ubuntu Desktop PCs and Android (Eclair) devices. H. For example, a PAN of eight Bluetooth-enabled LRUs of the system can include SCM 102, seat actuators 104 Bluetooth Wireless Technology Graham Roth May 22, 2013 Submitted as coursework for PH250, Stanford University, Spring 2012 Introduction. Therefore an inter-piconet scheduling (IPS) algorithm is required in order to efficiently coordinate the inter-piconet Bluetooth units and maximize the network capacity. The specification for the Piconet II system is to implement the DSR protocol for IPv42 on the Linux operating system. The transmitting slave is not notified of the change in the topology until after its buffer has already started filling up. It is revealed that the proposed system can be used to implement Bluetooth piconet and can be an effective means for the monitoring of any parameters of multiple systems. • A network consisting of two or more piconets. Example of frequency hopping. The application software running on the laptop contacts the cell phone when it is within range, and requests that it synchronize its database with the one stored on the laptop. Piconet is formed by one master and one slave as well as one master and multiple slaves. The radio designated as the master makes the determination of the channel (frequency-hopping sequence) and phase (timing offset—that is, when to transmit) that will be used A piconet can support up to eight devices. Piconets . DK-LM3S9D96) that comes with a PAN1325 "dougther board". The system will run on x86 based PCs and on ARM3 based Compaq iPAQs using IEEE 802. I want to establish a bluetooth piconet. Forming a piconet “from scratch”, such as the example case, consists of three  Sep 27, 2001 Each cluster of Bluetooth devices (called a “piconet”) has net effective bandwidth Example of 4-slave piconet : 3 is synch. Fun fact: bluetooth gets its name from a viking king, Harold Bluetooth, and the A personal area network (PAN) is a computer network for interconnecting devices centered on an individual person's workspace. Bluetooth is a wireless LAN technology used to connect devices of different functions such as telephones, computers (laptop or desktop), notebooks, cameras, printers and so on. A2DP defines the protocols and procedures that realize distribution of audio content of high-quality in mono or stereo on ACL channels. Although the number of piconets is minimized (see Remark 1), this scatternet probably would not perform very well in practice because the shared slave Prior to installation Disconnect the device from the power supply Protect against an accidental restart Verify safe isolation from the supply Therefore, Piconet A and Piconet F, Piconet A and Piconet D, and three Piconets form Scatternet. The hopping pattern is unique and derived from the clock and BT device address of the master. A piconet is a group of devices located within a few feet of each other that communicate over a shared high-bandwidth, short-range radio channel. I'd like to create a piconet using HC05 Bluetooth modules. For example, device 2 participates in piconets P0 and P1; device 2 is a relay node between piconets P0 and P1. I've been coding an Android Application to communicate to a Bluno Beele via BlueTooth Low Energy. Instead of having wired controllers, the PS3 implements Bluetooth technology to   Slide 19 of 35. The unit that carries the paging procedure and establishes a connection is by default the master of the connection. Bluetooth piconets are often established  Scatternet a device can be a Master in one Piconet and a Slave in another, or a Slave in both, but . Chapter 1 Performance of bridging algorithms in IEEE 802. A simple database search strategy should begin with the P AND I: cross infection AND (Handwashing OR Hand disinfection) . ABSTRACT Scheduling for Bluetooth Scatternets. The connection table of the SAPIFO 33. piconet;. Download the latest Bluetooth SDK via Simplicity Studio if you haven't done it. Once a piconet is established, the members randomly hop frequencies in unison so they stay in touch with one another and avoid other piconets that may be operating in the same room. 3 network topology is depicted in Figure 1. I declare that the work submitted in this thesis is my own, except as acknowledged in the For example, a Bluetooth dongle on a PC (or one built in) will act as a ‘master’ and send audio signals to a headphone, which is the ‘slave’ device. the algorithm. lectrical installation must be carried out in accordance with The e the relevant regulations (e. We'll go over services, characteristics, and how to control inputs and outputs on the Arduino via the LightBlue app on our phone. 100) of co-existing piconets, locatedwithineachother’stransmission range and using the compact system. It can then connect to a slave device using by paging it. Piconet is a Bluetooth network that consists of one primary (master) node and seven active secondary  Devices connect to each other to form a network known as a piconet, with up to For simple streaming audio device examples in many consumer applications,  This diagram shows that the master controls the sleep modes of the devices within the Piconet. edu Abstract—In this paper, a model for N mobile nodes that talk An example of a piconet is a connection between a cell phone and a headset using Bluetooth wireless technology. Mi•si¶c University of Manitoba, Winnipeg, Manitoba, Canada In this chapter, we introduce the bridging problem from the viewpoint of the altogether. A Arduino pro micro will be constantly requesting data from the 2 Systems and techniques are disclosed relating to wireless communications. A scatternet consists of two or more overlapping piconets. Bluetooth devices do not necessarily connect on a one-to-one basis. Bluetooth is a proprietary wireless technology intended for short-range communication that is overseen by the Bluetooth Special Interest Group. Bluetooth Basics a learn. An example: As soon as you enter the office, the calendar in your handheld computer is automatically updated to agree with the calendar in your office PC. As illustrated in Figure 1, 1. B. The A specific frequency-hopping sequence is used by all devices within each piconet. For example, multiple sensors can connect to a master device like smart . For device, which plays roles of slaves in more than one piconet, is a relay device. The original signal is spread  Meaning "tiny" network, a piconet is a Bluetooth network composed of two or more Bluetooth devices that operate in close proximity on the same channel and   Bluetooth, the wireless nodes are grouped in the form of clusters ( piconets in Bluetooth ) . There are six piconets in original scatternet. Multiple piconets with overlapping coverage areas form a scatternet. Fig 1: Bluetooth Scatternets and Piconets. IOException;. Each piconet may have only one master, but slaves may participate in different piconets on a time-division multiplex basis. The system offers services that enable the connection of devices and the exchange of a variety of classes of data between these devices. Example of a tripod robot (right), the corresponding CPG configu- ration (red  unique for the piconet and is determined by the Bluetooth address of the master. A device can be a member of two or more piconets, jumping from one piconet to another by adjusting the transmission regime-timing and frequency hopping sequence dictated by the master device of the second piconet. and occasional mobility. However, a unit cannot be a master in more than one piconet. Thanks for A2A. This may be achieved, for example, by using rendezvous points –pre-negotiated slots that a piconet master agrees to poll the gateway, and the Synonyms for piconets at YourDictionary. Figure 1c illustrates another configuration in which node A is master of piconet 1, node E is master of piconet 3, node B is an M/S bridge (master of piconet 2 and a slave of piconet 1), node D is a slave of piconet 1 and A group of devices synchronized in this fashion form a piconet. For example, the mobility of a node can be advertised (explicitly flagging) and then, whenever possible, it can be disallowed from becoming a piconet master to save reconfiguration time in the event of its movement. Since each piconet has only one master, then all the packets exchanged within a piconet will have the same unique access code which is called Channel Access Code (CAC). Piconet Example. For example, E sends string messages to A and F at the same time in the Scatternet formed by Piconet A and Piconet F; D sends string messages to A and J at the same time in the Scatternet formed by Piconet A and Piconet D. 2 SINAP SINAP exploits the information derived from the SAPIFO procedure. In such a scatternet of n devices with every piconet containing kslaves, there are d(n 1)=kepiconets. Some parts can be trivial in certain scenarios and quite complex in another. Duple x ( TDD ) protocol between devices in a piconet as well as the . It’s also used for a lot of modern video Example HID interface, from RN-42-HID User’s Guide. Bluetooth uses what is known as a master-slave structure, meaning one device is set as master and the other 7 devices act as slaves. A network of sensors (as discussed previously) is a good example of an  A policy increasing the utilization of available bandwidth in a piconet is presented . • Thus, piconet can have upto eight active nodes (1 master and 7 slaves) or stations within the distance of 10 meters. S. Piconet: A piconet is a network of devices connected using Bluetooth technology. For example, if the tool recovers a LAP of 36A2B4 and a UAP of 98,  bluetooth, frequency hopping, piconet, packet, inquiry, paging. A device that is a member of more than one piconet must schedule its presence in all the piconets in which it is a member. proximity of each other. Consider two piconets with a common node. In this example, the laptop acts as a master. network. Bluetooth is an example of personal area network. Perhaps the most fundamental is to control communication. g. On the left, a device is a master in one piconet and a slave in another. Figure 1 gives a description of the WINS node architecture. Master will transmit the audio to all the salve, while slave will play the audio at the same time. piconet example
