I flashed the light_bulb example(NRF5 SDK v.4.2.0) hex to an nRF52840 Dongle using nRF Connect.
After reset, LED2 lights blue.
I do have an existing Zigbee network using Zigbee2Mqtt and I want do connect the example bulb to it. But Zigbee2Mqtt does not show any join attempts from the light bulb example.
So my question is:
Is this example not intended to join a Zigbee network? Are there ohter examples that can connect to an existing network in this case? Or is something wrong?
