I'm trying to use Sparkfun's OBD-II-UART board to interface with a CAN network using a Raspberry pi 4. Upon connecting to sudo screen /dev/ttyAMA0 and when I send the commands, I'm not able to get any response from the OBD-II-UART board. Can anyone suggest why it is not communicating?
Can not communicate sparkun OBDII UART with Raspberry pi 4 over (minicom)
