    I am working on a project which required the use of the Berry GPS-GSM. We've had it for some time, approximately 3 months. We had success with it, set it up on a RPI4, connected the GSM module with a T-Mobile sim card and the GPS getting a fix. It was working fine 2 days ago with no changes to it's placement or use. Yesterday it stopped working, specifically we power on the Pi and the GPS-GSM GPS fix light flashes on and off once. Then the board has no activity, no power light or GSM light. It behaves the same each power cycle. There is no modification or physical damage to the board. I am looking for solutions or debugging ideas. Nothing on the board gets noticeably hot.

    Hi Pedro

    Do you have the module sitting ontop of the GPIO pins of the Raspberry Pi?  If "yes",  do you see anything from the GPS module if you look at the Pi Serial port?  you can try with;
    cat /dev/serial0
    or
    'minicom -b 9600 -o -D /dev/serial0'

    Can you show me the output of these two commands;

    lsusb
    dmesg | grep -E -- 'usb|cdc'
