🚧 Lat/Lon Format
Lat and Long are given in the following format:
Long: DDDMM.MMMMM[E|W]
Lat: DDMM.MMMMM[N|S]In the return example above:
00310.22460W,5129.71500N
can be expressed as:
003° 10.22460' W, 51° 29.71500' N
📘 Response Key
The expected response for the R7+GPS command:
longitude,latitude,course,speed,altitude,mode,satellites,hdop,time,date
| Data | Format |
|---|---|
| Longitude | DegreesMinutes.decimalMinutes E or W (DDMM.MMMMM[E|W]) |
| Latitude | DegreesMinutes.decimalMinutes N or S (DDDMM.MMMMM[N|S]) |
| Course | degrees |
| Speed | knots |
| Altitude | meters |
| Mode | 1 = no fix 2 = 2D fix 3 = 3D fix |
| Satellites | count |
| HDOP | 1-20 (1 = highest precision, 20 = poorest) |
| Time | hh:mm:ss |
| Date | DD-MM-YY |
R7+GPS,STREAM=n
1 = turns streaming on
0 = turns streaming off
When GPS streaming is turned on a position is output every second.

🚧 Streaming = ON
During streaming mode, other API commands work as normal.
R7+GPS,HOT
This gets the current GPS Hot status and reports 1 = ON, 0 = OFF.
R7+GPS,HOT=n
This sets the GPS Hot status where n=1=ON, n=0=OFF.
R7+TRACK,FREQ
This gets the transmit period enumeration and reports n = # (numbers listed below)
❗️ Request Tracking Frequency
Will report back the current tracking frequency being used. ie GPRS, Satellite or Distress Context
| Frequency enumeration | Tracking Frequency |
|---|---|
| 1 | 5 minutes |
| 2 | 10 minutes |
| 3 | 15 minutes |
| 4 | 20 minutes |
| 5 | 30 minutes |

This command will only configure the Satellite Context tracking frequency. It is not currently possible to configure GPRS or Distress context via the Serial API.
R7+VERSION
Returns the installed firmware version
/* Check Device Firmware */
R7+VERSION\r
