GPS: no signal #53

Closed ArcticSnow closed 5 years ago

ArcticSnow commented 5 years ago

The current issue with GPS is a complete lack of signal from the sensor. This is true for both our UiO script and also the simplest GPS example code.

Using the debug option in the WaspGPS.cpp, it points to problem in the function parseRMC(). See the output to teh serial when using the DEBUG option:

[GPS] parseRMC
[GPS] inbuffer2:,,V,,,,,,,,,,N*
[GPS] not connected

After some hardware testing, there seems to be an issue with antennas. No code problem.

Antenna problem confirmed! I'll send an email to Libelium
