Abstract: A wireless apparatus in ZIGBEE network has a host controller, a ZIGBEE module communicated the host controller and including a RF transceiver for receiving or transmitting a signal, a ZIGBEE stack engine connected the RF transceiver, a decoder connected the ZIGBEE stack engine, a memory, a minor serial interface, and a serial command manger. The decoder decodes an address signal from the ZIGBEE stack engine and stores the address signal to the memory, and transmitting a signal to the host controller. The host controller sends an address request serial command according to the signal to the ZIGBEE module. According to the address request serial command, the serial command manager shifts the address signal from the memory to the minor serial interface and transmits the address signal to the host controller.

Abstract: Disclosed is a ZigBee network healing method after the coordinator of the ZigBee network falls out and recovers subsequently. The method uses a router to determine whether a parent device of the router is the coordinator; if the router's parent is the coordinator, the router further determines a link status from the parent device; if the router determines the link status is not abnormal, the router activates a network recovery process.
