RPi 3B+ GPS on serial port

M95D

Hi.
I tried to use a GPS receiver connected to the RPi serial port. I can see the GPS getting a fix (led blink), I can see incomming GPS messages on /dev/ttyS0, location is turned on, but no application can get a location fix! I tried several.
I also tried changing GPS port in /system/build.conf, but no success.

Is there anything else I should do?

BTW, the default /system/build.conf indicates /dev/ttyAMA0 as the GPS port, but on RPi 3B+ that is the bluetooth device.

Thank you.

Try to set gps port in the build.prop to your serial device.

I did. I made a mistake above: It should be build.prop, not build.conf ! Sorry for the confusion.
