Designed to work with MangOH boards. Tested on MangOH Red with Legato 17.11. May work with other boards as well.

Monitoring GPS location is cool, but blocking up other important calls is way less cool, and multi-threaded programming is arguably not that cool either. This app will keep an eye on your GPS location and allow other apps to request the location.

You are free to copy and runs this code however you would like, however we recommend using a Git submodule to stay up to date.

Be sure you clone the submodules as well using git clone --recurse-submodules -j8 https://github.com/brnkl/mangoh-gps-monitor

Only tested on the WP85, so we have not included a Make recipe for other WP series chips yet. Using another chip? Submit a pull request or issue!

• WP85: make wp85

To use this app, setup the required Legato IPC bindings.

myClientApp.adef

...
bindings:
{
  myClientApp.myComponent.brnkl_gps -> gpsMonitor.brnkl_gps
}
...

Component.cdef

...
requires:
{
  api:
  {
    brnkl_gps.api
  }
}
...

Note that you will need to include this interface in your system definition (.sdef file), or tell mkapp/mksys where to find it with the -i argument. An absolute path works too but this can be a pain depending on how your project is setup.

myApp.c

double lat, lon, horizAccuracy;
uint64_t lastReading;
le_result r = brnkl_gps_getLocation(&lat, &lon, &horizAccuracy, &lastReading);
LE_DEBUG("GPS reading %s", r == LE_OK ? "succeeded" : "failed");

That's it!
