Joining Announce
All ZigBee devices send a ZDO Device Announce broadcast transmission when they join a ZigBee
network (ZDO cluster ID 0x0013). These frames are sent out the device's serial port as an Explicit Rx
Indicator API frame (0x91) if AO is set to 1. The device announce payload includes the following
information:
[Sequence Number] + [16-bit address] + [64-bit address] + [Capability]
The 16-bit and 64-bit addresses are received in little-endian byte order (LSB first). See the ZigBee
specification for details.
Commissioning pushbutton and associate LED
XBee devices support a set of commissioning pushbutton and LED behaviors to aid in device
deployment and commissioning. These include the commissioning push button definitions and
associate LED behaviors. The following features can be supported in hardware:
A pushbutton and an LED can be connected to XBee/XBee-PRO ZigBee RF Module pins 33 and 28
(SMT), or pins 20 and 15 (TH) respectively to support the commissioning pushbutton and associate LED
functionalities.
Commissioning pushbutton
The commissioning pushbutton definitions provide a variety of simple functions to help with deploying
devices in a network. Enable the commissioning button functionality on pin 20 by setting D0 (AD0/DIO0
Configuration) to 1 (enabled by default).
