icon SmsLoc is an application that queries the location of contacts without the use of mobile data. It uses GPS to retrieve current position and SMS for requests/responses.

SMS request format: `Loc?`
SMS response format: `Loc:LAT,LON,ASL,UTC_S,V_KMH,ACC_M,BAT_PCT`, where:
- `LAT, LON` are latitude and longitude in degrees rounded up to 4 decimal places.[^1]
- `ASL` or Above Sea Level is the absolute altitude as reported by the GPS in meters
- `UTC_S` is the timestamp of the GPS fix in seconds. The timestamp corresponds to the time of the actual fix, and not when SMS was received.
- `V_KMH` is the speed in kilometers/hour
- `ACC_M` is the accuracy reported by the GPS chip in meters
- `BAT_PCT` is the battery percentage of the device sending the response

WhatsNew:

Added permissions:
[x] READ_PHONE_STATE so resend on network alive can work (see #29)

Bugfixes:
[x] Fix debug print in startForeground (#26)
[x] Back pressed was ignored

Enhancements:
[x] Treat anything but 'Activity.RESULT_OK' as SMS sent error (#27)
- Responses: Retry sending SMS automatically (#29) -> waits for network and resends the sms
- Requests: Show AlertDialog, ask the user if resend
[x] Support for multiple location requests arriving during a single GPS fix

anti Anti-Features:
  • NonFreeNet (this application promotes/depends a non-Free network service):
    ⇒ Depends on openstreetmap.org for map data

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device.
