Garbled data

    I have the BerryImuGps mounted on top of the Raspberry Pi, however, whenever I run cat /dev/serial0 I keep getting garbled data. I tried to change the baudrate to 9600, 115200, and 4800 for both the raspberry pi and the berry gps module but none of the baud rates seem to be working.

    I have also attached the screenshot of the kind of the data I am receiving.

    Additionally, would it be possible to have the GPS module working if it is placed on top of the RS 485 Can Hat that is, in turn, placed on top of the raspberry pi? Or will I, in this case, need to connect the berry gps to the raspberry pi via the QWIIC connection?

    I’d appreciate any information!

    what do you get when using minicom?
    minicom 9600 -D /dev/serial0

    I am not familiar with the RS 485 Can Hat, however i did a google search and found a schematic and it looks like this board also uses the UART. You can only have one device connected to the UART interface on the Pi, which means you will need to use GPS via i2c

    If I have a can hat 485 put on top of the raspberry pi, will I still be able to connect the berry imu/gps via the QWIIC connector? The QWIIC connector seems to be using the same pins that the can hat is sitting upon.

     

    I’d appreciate any info.

     

    And I’ll attach the information about the output from running minicom a bit later.

     

    Thanks!
