This looks pretty good. Nice work.

Flashing green (every second) means, that STM32 microcontroller is sending out a CAN message. This is good. Alternating blue/red LEDs mean that RN52 Bluetooth module is in advertising mode. So you should see "BlueSaab v6" in the discovered device list on your mobile device.

One thing you could try is to see what comes out of STM32 on serial console of your computer. For this you will need to jerry-rig the wires in following manner:

*) FTDI orange wire -> UART2 Rx on BlueSaab
*) FTDI yellow wire -> UART2 Tx on BlueSaab
*) FTDI red wire -> UART1 VCC pin on BlueSaab
*) FTDI black wire -> UART1 GND pin on BlueSaab

Then open a terminal application on your computer using 115200 for baudrate setting and reset BlueSaab using reset button. Let us know what you see on the screen.
