Recently I upgraded my Zigbee Hardware from CC2531 to CC2652 and noticed an issue. (Multiple other people had the same issue.) I was unable to add new devices. Somehow routing and joining has issues.

Upgrading the firmware might fix it. To upgrade the CC2652 stick from Linux I used Kali Linux just because I had a work laptop with native Kali Linux running already. My stick came from eBay and has an embedded USB to serial adapter. You just need to push a button while pluging it in (BTN1) and you will see a /dev/ttyUSB0 in your logs popping up.

From the dev branch of koenkk I tried the new firmware (CC2652R coordinator) from

https://github.com/Koenkk/Z-Stack-firmware/tree/develop/coordinator/Z-Stack_3.x.0/bin

unzip CC2652R_coordinator_20211207.zip

I use CC2538-bsl.py to flash it (it works with CC2652 as well):

If you do not have it, you can clone it
git clone https://github.com/JelmerT/cc2538-bsl
(you might need to add pip3 install intelhex)

Then

./cc2538-bsl.py -p /dev/ttyUSB0 -evw ../CC2652R_coordinator_20211207.hex

Flashing should start and be finished in ~10 seconds.
