Rebooting coordinator causes all future packets sent from router/ed's to give 0x21 delivery errors

If I have a working network and I unplug the XStick (coordinator) and plug it back in, the network never heals. All routers & end devices will thereafter give 0x21 errors on all data sent to the coordinator.

Is there any way to rectify this? Do I have to reboot the end devices every time they start getting 0x21 errors???

I suspect Coordinator in your setup has changed its operational ID and channels when its unplugs. Now its not part of same network and other nodes are therefore not able to reach it for communication.

Now you have 2 options:

  1. Enabled Network Watchdog (NW parameter) on all nodes. Once they figure out (when watchdog will trigger) that Coordinator is no more in current network, they will leave network too and scan for Coordinator again and eventually join it.

2.Bring back Coordinator to original settings: check “Replacing a Coordinator” section in product manual to learn this process:
