Hello all,  
my device send gps position while moving over network (using sockets), i want to be able to save data when network is absent or not enough for network connection. What can be the best approach to save strings (nmea sentences) for a later send? Files? usually i get a string every 2 seconds… and i can save to file then later zip and send this file… is this the right way or I can use some built-in API ?
