Good news arrived eventually, one module (over 3) work like a charm !
I had to have RN52 & Atmega328 speak @ the same baudrate (i.e. 9600) and since my CDC is fully operational and great pleasure to play with !! Thanks again guys, that's amazing !

My two other modules remain reluctant to give me access to RN52's command mode and as I made lots of attempts with my first module, I can't remember which way worked for it...
I tried via
- RN52 programming code loaded in ATmega328
- UART RX & TX connections with an Arduino-Uno board
- FTDI-USB cable hooked
None of them gives me the magic CMD message to change RN52's settings. I keep on trying and I'm confident it will eventually work.

I read in RN52's datasheet that if GPIO7 pin is set to low (grounded) RN52 works at 9600 bauds, would it be an easy way to deal with these communication issues between chips on the module ?
