**0x0013  Joining Announce**

All ZigBee devices send a ZDO Device Announce broadcast transmission when they join a ZigBee network (ZDO cluster ID 0x0013). These frames will be sent out the XBee's UART 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]0x0013
