Coordinator router zigbee pairing after rebooting

Hello!
The problem is that I have a pair coordinator router and I want to understand what I need to do so that when the router is rebooted, the coordinator will find this router again and pair with it.

Thanks in advance for your help!

Hello @Georgeee 

If the persistent data is not used (as on the Zigbee examples of the STM32CubeWB 1.21.0), you can connect to the coordinator only for a limited time "ZB_BDBC_MinCommissioningTime" that can be set to a maximum value of 254 second. So, you need to implement the Persistent data management to be able to connect to the coordinator any time after the first connection.

Take a look at that on the STM32_Zigbee_DM_Workshop (example, Youtube videos and PDF slides descriptions). You can also have a look at the AN5492.

Best Regards.
