GPS does not always work in the field... #38

Closed ebgoldstein closed 2 years ago

ebgoldstein commented 3 years ago

The GPS does not always provide a location, and i was having some issues with exceptions..

I adjusted the script slightly so -9999 is the default and new values write on top (i will link my commit to this issue), but i am not sure that gps.next() is the best way to make sure a position is returned... i know this is an old S.O. thread, but i wonder if it hints at a way to deal with it... https://stackoverflow.com/questions/6146131/python-gps-module-reading-latest-gps-data
