updateChannelList

Check if the Communications Toolbox™ Wireless Network Simulation Library support package is installed. If the support package is not installed, MATLAB® returns an error with a link to download and install the support package.

wirelessnetworkSupportPackageCheck;

Initialize the wireless network simulator object.

networkSimulator = wirelessNetworkSimulator.init();

Create two Bluetooth EDR nodes, one with the "central" role and other with the "peripheral" role. Specify the position of the Peripheral node in meters.

centralNode = bluetoothNode("central");
peripheralNode = bluetoothNode("peripheral",Position=[1 0 0]);

Create a default Bluetooth BR/EDR connection configuration object to configure and share a connection between Bluetooth EDR Central and Peripheral nodes.

cfgConnection = bluetoothConnectionConfig(CentralToPeripheralACLPacketType="2-DH3",PeripheralToCentralACLPacketType="2-DH5");

Configure connection between the Central and the Peripheral nodes.

connection = configureConnection(cfgConnection,centralNode,peripheralNode)

connection = 
  bluetoothConnectionConfig with properties:

    CentralToPeripheralACLPacketType: "2-DH3"
    PeripheralToCentralACLPacketType: "2-DH5"

Create and configure a networkTrafficOnOff object to generate an On-Off application traffic pattern.

traffic = networkTrafficOnOff(DataRate=200,PacketSize=27, ...
    GeneratePacket=true,OnTime=inf);

Add application traffic from the Central to the Peripheral node.

addTrafficSource(centralNode,traffic,DestinationNode=peripheralNode);

Schedule channel list update at the Central node at 0.05 seconds to use channels 0 to 40.

scheduleAction(networkSimulator,@(varargin) updateChannelList(centralNode, ...
    0:40,DestinationNode=peripheralNode),[],0.05);

Add the Central and Peripheral nodes to the wireless network simulator.

addNodes(networkSimulator,[centralNode peripheralNode]);

Specify the simulation time in seconds.

simulationTime = 0.3;

Run the simulation for the specified simulation time.

run(networkSimulator,simulationTime);

Retrieve application, baseband, and physical layer (PHY) statistics corresponding to the Central and Peripheral nodes.

centralStats = statistics(centralNode);
peripheralStats = statistics(peripheralNode);
