This android-studio project repo contains a few main android library 'modules' which allows Android phones to connect and read/parse GNSS (GPS/GLONASS/Galileo/BeiDou) position data from existing Bluetooth GNSS Receivers like the EcoDroidGPS Bluetooth GPS Receiver (https://www.clearevo.com/ecodroidgps) - which is the main target device and developed by the same author of this project and also others similar 'nmea-like-messages over RFCOMM' devices like the HOLUX Bluetooth GPS devices, the Garmin GLO, etc.

ublox M9N: "UBLOX XY Accuracy" and "UBLOX Z Accuracy" stop being reported after some minutes #7

I don't know if this is an issue with the ublox M9N itself or with your App.

I get updates for around 3 minutes or so after powering the GNSS module. Then position and "non UBX info" keeps getting reported but the UBX messages stop for some reason.

Fixed after some thinking and testing. All that is needed to make Accuracy infos ($PUBX messages) work is to increase the baud rate. I had it on 9600 but this seems to be a bit low. Increasing to 115200 fixes the issue with the missing accuracy info.

The only downside of this is that the Bluetooth module also has to be reconfigured to the higher baud rate.
