Well, we'll have to start from the ground up:

1. Are you sure you are using 6.1 hardware and not 6.0? There's difference in pinout from STM32 to RN52 between the both.
2. Any output on serial from UART2?
3. Please post (as good quality as possible) pictures of the top and bottom of the module here. I'll try to see if something catches my eye.
4. Just out of curiosity, do you have the part number for RN52 you bought? Low probability but just checking if by any chance you were given a Bluetooth module with some old firmware on it.
