Hello everybody,
I'll try to modify the ble uart example. The target is, to get data from two different nus Services (different characterisitv uuids). They are both initilised...
I basically need to use two UART instances with the BLE Buttonless DFU Template App.
I started using the Serial library but apparently it's no longer supported.
The methods...
