Other Parts Discussed in Thread: Z-STACK
- I have 30 end devices power on at the same time and request to join the same network, given the air congestion, it's acceptable that some of them fail to jion. So the devices join again 3 seconds after failure until successful join.
- the problem is that some devices will never join successfully, even if I turn off most devices to reduce congestion. From the sniff log, I know the end device send a association request and get a response from the coordinator which didn't send a network key to end devices later. Also, if I reboot the coordinator, the device can successfully join the network. So I think the problem is on the coordinator side.
- An additional point is that it's ok to join if the 30 end devices join one by one, not at the same time. Has anyone encountered the same problem? Please help analyze it, thanks.
