I am new to zigbee and wonder about lots of things :)

What bothers me most, is that I cannot get an end device reconnect after I Powered it off without restarting the coordinator as well (I play around with Thermostat and Temperature_Sensor example)
I read a bit along different sites, including the issues here and sort of understood that there is a "stack" which should handle that. But it does not happen with my 2 ESP32-C6 Super mini boards (from aliexpress, no idea who made them).
Same problem, whe power cycling or resetting the coordinator, the sensor does not get reconnected to the network...

I am a bit reluctant to open an issue, because it might very well be possible that I miss the obvious due to my poor knowledge of zigbee standard

I feel that I miss some very substantial basics of he whole zigbee world and yould like to fill those knowledge gaps, but so far, I only found some fairly basic tutorials on how to install arduino IDE and create example prjects that don't explain much of the whole zigbee concept and network topology

So I hereby ask if anyone has some good sites they can recommend to get a least a little background knowledge on how things are organized in the zigbee world.

thanks

Hi@PerennialNovice, if you can post a logs from both devices when they are failing to connect it will help me to resolve your problem.
Please set in Arduino IDE Tools menu -> Debug Level to Verbose, in order to have logs in the Serial Monitor. Also if you can select Zigbee mode to ED or ZCZR (depends on the example) to use the DEBUG mode also.

Also (may not be the case), I recommend using some branded boards or the best Espressif dev kits, you can also buy them on Aliexpress in Espressif Official Store. Lot of mini boards have poor antenna, which is causing issues when connecting/reconnecting. Can confirm with the logs :)

For the Zigbee library there is no documentation yet, as the library is still a lot in progress and bringing a lot of fixes and new features in time. But the documentation is planned to be done.

About the Zigbee network topology you can find a lot great videos on YouTube. I am sure you can find them yourself :)

Sorry for the late reply, I have been busy on other stuff...

I'm trying to recreate the Reconnect issue, but so far no success - which in another way is success ;)
I think part of the issue is that serial communication does not get restored after a reset or power cycle. Which might as well be a PC problem and have nothing to do with the ESP32
I also ran in issues when I used certain types of USB hubs (mainline very slim ones)
So the actual setup is maybe not as trivial as one might think at first ...
Before I move on with this project I will update everything to the latest versions

thanks so far!

Well, seems I was a bit quick with my conclusion. I worked twice, that after a reset the sensor reconnected to the coordinator...

Here's the log from the sensor (end device) directly after a reset (software download). Before communication between sensor and coordinator was fine.

It does not fail consistently, sometimes I can restart either ED or ZCZR and the communiscation automagically is restored.
Is this expected behaviour, that once a connection betweeen ED ad ZCZR was succesfully established, upon reboot of any participant the connection is restored without any further interaction from the user / user code?
