CC1352P: Z-Stack server: ZigBee working correctly but impossible to add new devices

Part Number: CC1352P
Other Parts Discussed in Thread: Z-STACK,

Hi everyone,

We have a strange situation with a customer's life system running on Z-Stack Linux server and stack version

The customer has about 15 end devices connected to the system which are working fine. He can remove devices but he is unable to add new devices. When opening the network, there is the WK_SET_PERMIT_JOIN_REQ command in the log and it looks like it has been executed correctly without error.

However, in the sniffer log there is no answer to the device's beacons at all. As we would need to get one device paired in order to obtain the key, I cannot say if the system has actually sent a permit joining to the network.

Attached the ZB server's log with high verbosity. We did not find anything particularly useful except a few but not very frequent SRSP timeouts. Maybe a more experienced eye will notice something more useful. The interesting parts starts from line 10423.

Experience with other cases where we were not able to get extended logs tells us that all this will be resolved by a hard reset and restoring configuration but as this is not the first time that we are facing the problem (in the past with 4.x stack versions), it would be useful to understand why this happens.
