|
|
|
+This file listens on the GPS `tty` interface (`/dev/ttyGPS`) for GPS
|
|
|
+messages and sends messages to the Inter Process Communications (IPC) hub
|
|
|
+with GPS updates.
|
|
|
+
|
|
|
+Note that the `/dev/ttyGPS` should be setup system wide before this program is run.
|
|
|
+This is done by the Popufare system by creating a symbolic link to the appropriate
|
|
|
+underlying `tty` device that the GPS is connected to.
|
|
|
+
|
|
|
+`gps_minder` listens for `GPRMC` and `GPGGA` NMEA messages to update it's GPS position.
|
|
|
+
|
|
|
+Once received, the `gps_minder` will send a `GPS_MESSAGE` to the IPC so other services
|
|
|
+can get the GPS update.
|
|
|
+
|
|
|
+GPS updates will only occur once at least 3 satellites have been found.
