Serial output from the usb dongle

cu can be used to check the output. Hint, stop serial with "~." 

cu -l /dev/ttyACM0 -s 460800 

Then start a python service to translate the serial to mqtt

python3 py/nrf_mesh/nrf_mesh.py

mosquitto_sub -t 'nrf/#' -v | ts

The "| ts"  is a pipe that adds timestamp

subscribing to the mqtt topic would then show an output format inspired from zigbee2mqtt that allows to mix the custom nrf devices into the rest of the automation chain
