I would guess the 8 seconds in

timeout = time.time() + 8

is too short. Most GPS receivers repeat a sequence on NMEA sentences and 
the code is specifically looking for $GPGGA. Add

print(buff)

to see the sentences being received. I use the $GPRMC since I'm interested 
in the position, speed, and heading. It's a different format but if you 
only want lat/lon you could decode it in a similar fashion as the $GPGGA.
