ZigBee Explicit Transmit Packet
Frame Type: 0x11
This frame type is provided for software compatibility with other XBee modules and for sending
GPM requests. If neither of these is required, then frame type 0x20 is recommended for data
transmissions from this module. An example of a GPM request is given below:
