LoNet - GSM/GPRS/GPS Breakout


There are some mistakes on the documentation SIM808_GPSApplication_Note.pdf and on the Wiki

  1. AT+CGPSINF=0 gives the latitude BEFORE the longitude
    , , , , , , , ,

  2. the speed is in meters per seconds, not knots

  3. How can we deal with West longitudes or South latitudes using AT+CGPSINF=0?
    does the command reply negatives coordinates?, or are we supposed to use other modes like AT+CGPSINF=4 (which means that AT+CGPSINF=0 is useless)

=> We have the same problem with AT+CIPGSMLOC, no information for West longitudes or South latitudes

I really like what you say,can I make friend with you?
