Re: GPS MODULE not gives data according to my location

hello everyone
i have the same module as arun_9998 .my problem is i received more data format viz.GPGGA,GPGSA,GSV and many more but i want only one as GGA format.i tried input commands in flash magic with <CR><LF>.
but nothing happened.my commands is :

$PSRF103,00,01,00,01*20

for query of GGA message.

Let the GPS work around 20 or 30 minutes and you can get accurate data from your GPS module.;-)
