Hello I'm working with Zigbee Dimmable Bulb example. Testing environment is as followed:
nRF52840DK
SmartThings Gateway
SmartThings iOS app.
After changing the Zigbee channel to 14 in the example everything works great.
The problem occurred when I was trying to add the electrical measurement cluster to the above example.
After that, the device is not discoverable in the SmartThings App.
Can anyone more experienced in Zigbee could take a look on the attached code ? I can't figure out what am I doing wrong.
Best Regards,
Jakub
