    Hello i set up my BerryGPS IMU v3 with the current Raspios (2020-08-20-raspios-buster-armhf-full) on my Raspberry PI 4 8GB

    I tested it outside with clear sky view but i get no GPS data and also none of the LEDs lights up on start.

    Here is the serial output: minicom -b 9600 -o -D /dev/serial0

    Hi

    The LED will only light up with it has a GPS FIX.

    If you are not using an external antenna, can you confirm that the switch is in the 'int' position.

    I see that you have it mounted to something. When out side, is the GPS unit facing the skype and not being blocked by whatever you have it mounted to?

    Hi Mark,

    yes the position of the switch is int and the board is mounted behind a touch screen but i tested without the back cover so the gps unit was not blocked.

    Thank you,
    Béla

    Is there a fix for this? I'm also having the same problem

    you can try resetting the GPS and monitor the status of the antenna when it starts back up.
    You will need to open two terminal sessions

    1. First, stop gpsd
    sudo systemctl stop gpsd.socket
    2. view the GPS console with minicom in session 1
    minicom -b 9600 -o -D /dev/serial0
    3. in session 2, send a reset command to the GPS
    echo -e -n "\xb5\x62\x06\x04\x04\x00\xff\xff\x02\x00\x0e\x61" > /dev/serial0
    4. In minicom, confirm you get these three lines. (there will be other NMEA in-between)

    $GNTXT,01,01,02,Resetting GNSS*3B
    $GNTXT,01,01,02,ANTSTATUS=INIT*3B
    $GNTXT,01,01,02,ANTSTATUS=OK*25

     

    The last check is to have nothing else connect to the Raspberry Pi and have it outside with clear access to sky (not near a building or trees) and the GGPS facing skyward . Leave it for 1hr. You will be able to tell if it gets a fix because the LED will start flashing.
