I got it working! #1

This is actually not an issue, I wanted to say thanks for this project! This project was my first step into Arduina and Lora :-)

For anyone who also likes to built this I wanted to share my struggle and solution: After quite some trial and error I got this lora device working. My biggest challenge was getting the GPS to work. The arduino_test_SoftwareSerialExample worked fine, the arduino_test_GPS worked fine also (I got perfect longitude and latitude coordinates), but ... the main program arduino_juniorIOT_Lora32u4 gave no correct GPS fix....

Here is my tip: after installing the libraries NeoGPS-master.zip and NeoSWSerial-master-DamiaBranch.zip, you also have to replace these header files: GPSfix_cfg.h and NMEAGPS_cfg.h (get them from the libraries/NeoGPS folder) That did the trick.

One request: I am looking into power-down/sleep options to save battery. I am thinking of sending the info once every hour to the TTN. If you have any tips for that...

Best regards, and again many thanks for this great project.

Did you got it working in sleep-mode?

No I never got to that point. The TTN network went from V2 to V3 and then my configuration broke. I never got it working after that, but will try again soon.
