Once you follow these steps, you will no longer have a log in console on the Serial RX/TX pins, you will have to use a monitor+keyboard or ssh into your Pi! (or remove the HAT and undo the edits)
Set up the Pi to release the console pins
Start by logging into your Pi using a monitor/keyboard or via ssh
|
|
Run sudo raspi-config to open up the configuration page and select Interfacing Options or Advanced Options (it may be one or the other) |
|
|
Select Serial |
|
|
Select NO |
|
|
Keep the Serial Port Hardware enabled |
|
|
Thats it! |
Run sudo shutdown -h now to shutdown your Pi safely.
Remove power, attach the GPS hat and re-power the Pi
After rebooting the Pi for the above changes to take effect, you can proceed with testing the GPS!
