Modifying code to recive only RMC output in GPS

Question

I am using GPS module for my application. I want only the RMC data. So what am I supposed to do in my code to get only this data, i.e all the other formats like GGA,GSA,VTG should be disabled.

Please Help. Thanks

You cannot disable the other messages, and there is no reason to do so. Some GPS units support commands to enable/disable messages, but it is anything but standard.

Simply use a switch statement in your code on the sentence identifying field, and have a case block for GPRMC.
