Hi All!
I would like to implement the DTM nterface over USB VCOM instead of 2xUART (from examples).
Is it possible co-work USB driver (VCOM) and DTM from samples together...
Hi All,
I use 2 peripheral and 6 Central roles coexisting.
Not clear the order of conn_handle number assigned by SD during BLE Connection.
For example.
After Central...
I am new to nRF programming. My "far away goal" is to make a BLE sensor mesh with a centralised data collection.
Currently I am deciding what libraries to start playing...
