cli_agent_router and multi_sensor example with nRF5_SDK_for_Thread_and_Zigbee_v4.1.0 nrf52840
problem:
The coordinator restarts occasionally, and the zed cannot rejoin until reset.
When restarting the ZED, ZED join and get a new short address.
the log info from ZED:
<info> app: Unable to join the network, start network steering.
<info> app: Started network rejoin procedure.
...
<info> app: Unable to join the network, start network steering
...
<info> app: Unimplemented signal (signal: 21, status: 0)
...
<info> app: Unable to join the network, start network steering
...
<info> app: Network rejoin procedure stopped as scheduled.
The ERASE_PERSISTENT_CONFIG ZB_TRUE on both ZED and ZC/ZR.
When the coordinator restarts, the PANID conflicts with the existing ZR and cannot be specified.
How to solve that the coordinator restarts and the ZED or ZR rejoin ?
