UART GPS ANDROID 6.0.1

leonardoprates — Fri, 24 Jun 2016 17:17:19 GMT

I need enable a UART GPS in Android 6. My board is similar to SabreSD. I can see NMEA data in console using cat /dev/ttymxc3. But how I tell to Android use this UART4 to get and parse NMEA?

I have used this code GitHub - kconger/android-serial-gps-driver: Android Serial GPS Driver and I get GPS working. I have another issue that I can't get AGPS working. I'm using this gps.conf. Could anyone give me directions? For supl.google.com is certificate necessary and how get one?

Hello Leonardo,

The GPS conf looks ok. Are you enabling the use of wireless networks and gps satellites?, do you have the logcat or how are you defininf that the a-gps is not working?
