Problems replacing GM862-GPS with R-GM862-G4

  • Dear Sirs
    I trying to replace the GM862-GPS module with a your R-GM862-G4, there are two different problems:


    A) Often the response from the AT$GPSSW command, it only returns
    $GPSSW:


    when it respond, return
    $GPSSW: GSDe_4.1.2 -P9_CCK F+ 03/21/2014 080 TELIT


    the module firmware is 10.01.110


    the command list is:

  • Thanks Mazen,
    I'm trying to develop a firmware version where the code can be the same for the GM862-GPS and for the R-GM862.
    I will insert the GPS command as reported in the migration document, but if I understand well I'd bought a wrong version of R-GM862.
    The correct replacement for my firmware (where the GM862-GPS automatically send the NMEA message) is not the R-GM862-GI but the R-GM862-GE?
