Datasheet

If the SD card was initialized OK, it will read a sentence from the GPS, check the checksum and if its

a proper sentence, and then log it.

You can customize this basic example by changing the sendCommand in the top of setup(), for

example you can turn on different sentences (although RMC and GGA are the most desirable,

we've found). Or change the update rate to 5Hz instead of 1Hz

You can also set it so only 'fixed' data is logged - that is, there has to be valid location data. Doing

so reduces power usage and saves space but its harder to debug because you don't get the

timestamps that are in the RMC sentences.
