Hello everyone!!
So I have create a working zigbee light switch using nrf52840 dongle. Now my next step is that instead of using button present in the dongle I have to control it using laptop keys(to be precise using UART). Here is the main.c file code of zigbee nrf52840 dongle(Ignore the FOTA lines as I am not using ble):
