    I am using the BerryGPS IMU 4 on a raspberry Pi 4 but I am unable to get a fix. I have tried a bunch of different locations including sitting on my roof for two hours and it still does not get a fix. I am getting a message:

    - GNTXT, 01, 01, 01, More than 100 frame errors, UART RX was disabled*70

     

    I am using the internal antenna and I have the board switch set to INT. I have tried using the commands to stop echo (/usr/bin/stty -F /dev/serial0 -echo) but the error message continues. I have double checked my solders for the header and they should all be good.

    Any help on what to do would be very much appreciated!

    Have you disabled the login shell on the serial?

    Yes, I have disabled the login shell and enabled the serial hardware.
