Lat/Lon Format

Lat and Long are given in the following format:

Long: DDMM.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

🚧

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
