$GPRMC and NMEA how to extract from report

Posted on 16th Feb 2014 07:03 pm by admin

Hi There,

Im a little bi lost and not sure where to start with this one, ive got a small gps receiver which im
polling over a serial connection, each time i poll the device i get a load of rubbish back like this...

Code: $GPRMC,223450.000,A,5310.5785,N,00226.2042,W,0.0,25.8,291109,,,A*49

$GPGGA,223450.000,5310.5785,N,00226.2042,W,1,06,2.1,22.3,M,59.1,M,,0000*7D

$GPVTG,25.8,T,,M,0.0,N,0.0,K,A*32

$PMST200,00,204*1E

$PMST200,00,204*1E

$PMST200,00,204*1E

$PMST200,??,204*1E

$PMST200,??,204*1E

$PMST200,??,204*1E

$PMST200,??,204*1E

$PMST200,??,204*1E

$PMST200,??,204*1E

$GPGLL,5310.5785,N,00226.2042,W,223450.00,A,A*73

$GPGSA,A,3,02,04,05,07,08,10,,,,,,,4.5,2.1,4.0*39

$PMST200,??,204*1E

$PMST200,??,204*1E

$PMST200,??,204*1E

As they are never ever in the same order i cant really use reg_exp to get what i want, basically im
trying to capture the following and then use split to break them down further and insert into a DB

Code: $GPRMC,223450.000,A,5310.5785,N,00226.2042,W,0.0,25.8,291109,,,A*49


how can i just get it to extract that line and nothing else unless i ask it to????

the output from the serial devic come is extract using this

Code: $read = $serial->readPort();

than i just echo read etc etc and get my text which is further up, any ones help
or suggestions would be brill...

thanks
