Generic Android driver for serial and USB(-to-serial) GPS receivers that use the NMEA or UBX protocol.
This driver is included by default with Bliss OS and can be enabled by editing your build.prop with a text editor (or another suitable tool such as BuildProp Editor) and adding the configuration lines in the table below in the format key=value
| Key | Value | Required | Purpose |
|---|---|---|---|
| ro.kernel.android.gps | ttyUSB0 | Yes | The TTY of your GPS receiver, such as ttyUSB0, ttyS0, ttyO1 etc |
| ro.kernel.android.gpsttybaud | 9600 | No | The baud rate of your GPS receiver, if not specified this defaults to 9600 (baud) |
| ro.kernel.android.gps.max_rate | 1 | No | For u-blox receivers only, this is the poll rate in seconds if between 1..65, otherwise milliseconds if between 250..65000, defaults to 1 (second), recommended value is no faster than 500 (milliseconds) |
| ro.kernel.android.gps.time_sync | 0 | No | Number of seconds drift between system and GPS clocks before driver synchronizes system time with GPS time, recommended value here is 20-30 seconds, a value of 0 (the default) disables this feature |
This is a list of devices that have been confirmed working by Bliss staff.
