I have a GPS with a GPRS with an active SIM card. How do I go about directing the GPRS data to a specific website (IP port_ I believe port 3500 is used). I do not know how to acquire the GPS/GPRS data transmission and do not know how (or what should be done) to process the incoming data.
I am not familiar with the route the GPRS data goes and how to acquire and process it. I assume it would need HTML/XML. I would like to process in real time.
Also what format would a GPS normally send data? GPX, csv?Answer1:
I can't be much help with your first question, but as for your second question;<br /> Most GPS's will send information in a format call NMEA. It is a series of text sentences one after the other sent serially.
The sentences will look somethink like this:-
$GPGGA,092750.000,5321.6802,N,00630.3372,W,1,8,1.03,61.7,M,55.2,M,,*76 $GPGSA,A,3,10,07,05,02,29,04,08,13,,,,,1.72,1.03,1.38*0A $GPGSV,3,1,11,10,63,137,17,07,61,098,15,05,59,290,20,08,54,157,30*70 $GPGSV,3,2,11,02,39,223,19,13,28,070,17,26,23,252,,04,14,186,14*79 $GPGSV,3,3,11,29,09,301,24,16,09,020,,36,,,*76
Not pretty, but they work quite well. The systems on the bridge of a ship use this format to pass information between each other.
You will find more information <a href="http://en.wikipedia.org/wiki/NMEA_0183" rel="nofollow">here</a> and <a href="http://www.nmea.org/" rel="nofollow">here</a>
If you only want to pick out one or two sentence types, it shouldn't be too difficult. I think the hardest part will be actually interfacing with the GPS to allow you to receive the sentences in the first place.
