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!
