plugmate-virtual-sensor-access.ino
Example of using the Android Location API to read coordinates transmitted by the host, as PlugMate has no physical GPS.
PlugMate virtualizes peripherals like GPS. This code uses standard Android APIs. The host must have permission to share its location with the PlugMate client. Data arrives via the secure tunnel. No physical location permission is required on the card, but the app must request ACCESS_FINE_LOCATION permission at the standard Android UI level.
