While trying to implement the Asset tracker example (in particle documents), I bumped into the issue that GPS shows that it has gotten a fix on the position (by turning the "GPS FIX" led off) but the function .gpsfix() returns 0, so no data is collected.

My Hardware setup: I had replaced Electron with a Photon (don't think it matters here!). Used USB to power up and also used external Antenna.

After discussing the issue on forum, I worked on https://github.com/rickkas7/AssetTrackerRK by rickkas7. His library is based on TInyGPS++. Now the module is working perfectly. So it seems like the issue was with the Adafruit GPS library.

It would be great if the problem with Adafruit library is resolved!
