    Syntax

    attPDU = bleATTPDU(cfgATT)

    Description

    attPDU = bleATTPDU(cfgATT) generates a Bluetooth® low energy (LE) attribute protocol data unit (ATT PDU) corresponding to the Bluetooth LE ATT PDU configuration object cfgATT.

    Open Live Script

    Generate two unique Bluetooth LE ATT PDUs of the type 'Read by type request' and 'Error response'.

    Create a default Bluetooth LE ATT PDU configuration object.

    cfgATT = bleATTPDUConfig;

    Set the Bluetooth LE ATT PDU opcode to 'Read by type request'.

    cfgATT.Opcode = 'Read by type request'
    cfgATT = 
  bleATTPDUConfig with properties:

           Opcode: 'Read by type request'
      StartHandle: '0001'
        EndHandle: 'FFFF'
    AttributeType: '2800'

    Generate a Bluetooth LE ATT PDU using the corresponding configuration object.

    attPDU = bleATTPDU(cfgATT)
    attPDU = 7x2 char array
    '08'
    '01'
    '00'
    'FF'
    'FF'
    '00'
    '28'

    Create another Bluetooth LE ATT PDU configuration object, this time using the name-value pairs. Set the Bluetooth LE ATT PDU opcode to 'Error response'.

    cfgATT = bleATTPDUConfig('Opcode','Error response')
    cfgATT = 
  bleATTPDUConfig with properties:

             Opcode: 'Error response'
    RequestedOpcode: 'Read request'
    AttributeHandle: '0001'
       ErrorMessage: 'Invalid handle'

    Generate a Bluetooth LE ATT PDU corresponding to this configuration object.

    attPDU = bleATTPDU(cfgATT)
    attPDU = 5x2 char array
    '01'
    '0A'
    '01'
    '00'
    '01'

    Input Arguments
