    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 = 7×2 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 = 5×2 char array
    '01'
    '0A'
    '01'
    '00'
    '01'

    Input Arguments
