Get statistics of Bluetooth BR/EDR node

Since R2022b

    Download Required: To use statistics, first download the Communications Toolbox Wireless Network Simulation Library add-on. For more information, see Get and Manage Add-Ons.

    Description

    example

    nodeStatistics = statistics(bluetoothBRNodeObj) returns the statistics of the Bluetooth® basic rate/enhanced data rate (BR/EDR) node object bluetoothBRNodeObj.

    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.

    networkSimulator = wirelessNetworkSimulator.init;

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

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

    Add a random waypoint mobility model to the peripheral node. Set the shape of the node's mobility area to "circle".

    addMobility(peripheralNode,BoundaryShape="circle")

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

    cfgConnection = bluetoothConnectionConfig;

    Configure the connection between the Central and the Peripheral nodes.

    connection = configureConnection(cfgConnection,centralNode,peripheralNode)
    connection = 
      bluetoothConnectionConfig with properties:
    
        CentralToPeripheralACLPacketType: "DH1"
        PeripheralToCentralACLPacketType: "DH1"
                           SCOPacketType: "None"
                     HoppingSequenceType: "Connection adaptive"

                        PrimaryLTAddress: 1
    
    

    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);

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

    centralStats = statistics(centralNode)
    centralStats = struct with fields:
            Name: "Node1"
              ID: 1
             App: [1x1 struct]
        Baseband: [1x1 struct]
             PHY: [1x1 struct]
    
    
    peripheralStats = statistics(peripheralNode)
    peripheralStats = struct with fields:
            Name: "Node2"
              ID: 2
             App: [1x1 struct]
        Baseband: [1x1 struct]
             PHY: [1x1 struct]
    
    

    Input Arguments

    collapse all

    Bluetooth BR/EDR node object, specified as a bluetoothNode object or an array of bluetoothNode objects. If you specify this input as an array of bluetoothNode objects, the nodeStatistics output is an array of structures.

    Output Arguments
