As for information on UART, you should be probing UART2 only for debug information. You would only see information on UART3 using a logic analyzer of some sorts as that's the interface that's used for RN52 <-> STM32 comms.

What you should see as an output on serial console is:

BlueSaab
Hardware version: 6.1
Firmware version: 6.1.1

If you are seeing gibberish, I'd suggest you check the serial connection. Have you connected GND from FTDI as well?
