关于多个协调器下的组网环境

如何让终端做到对某个协调器请求次数过多时放弃对其入网请求：

ZED /ZR 发送的是beacon request    ZC/ZR回复的是beacon

你可以在beacon 的处理函数上相想办法:

/****************************************************************************
 * @fn          ZDApp_beaconIndProcessing
 *
 * @brief       This function processes the incoming beacon indication.
 *
 *              When another task (MT or App) is registered to process
 *              beacon indication themselves, this function will parse the
 *              beacon payload and pass the beacon descriptor to that task
 *              If no other tasks registered, this function will process
 *              the beacon payload and generate the network descriptor link
 *              list.
 *
 * @param

 * @return      none
