Standalone Safesky device based on Raspberry pi 4


I am trying to assemble a tablet device with a Raspberry Pi 4 Model B and a high brightness display.

The idea is to be able to use Safesky in a safe and friendly way, without having to depend on a cell phone battery, with a larger and fixed touch screen on the instrument panel, and one that is readable in sunlight

I am using a USB GPS receiver and have installed several versions of Lineage OS. All other apps have location access, Skydemon for example, but SafeSky does not. Of course I have reinstalled the application several times and checked the location permissions.

I have also tried using GPS CONNECTOR whitout success.

Can you give me some guidance?

Greetings and thanks in advance.
