An Arduino Sketch for an GPS-Tracker to work with The Things Network. This Sketch uses TinyGPSPlus https://github.com/mikalhart/TinyGPSPlus the Rocketscream Low-Power library https://github.com/rocketscream/Low-Power and the Arduino LMIC-Library by MCCI Catena https://github.com/mcci-catena/arduino-lmic The hardware used is an Afafruit Feather 32u4 Lora with the Ultimate GPS featherwing.
To fit into the memory of the 32U4 with the MCCI Catana LMIC, please add the follwoing lines to your lmic_project_config.h
#define DISABLE_PING
#define DISABLE_BEACONS
For the non OTAA version it is also possible to disable JOIN and free up more memory
#define DISABLE_JOIN
Please keep in mind that you have to delete/uncomment these settings for other projects.
The folder ttn contais the payload decoder for TTN (V2) and TTS (V3).
The folder node-red contains a sample flow adding a geohash and storing data in InfluxDB.
Changes:
- Added versions for OTAA and LowPower
- Enable SBAS
- Added support for TTN Mapper integration from within TTN console (HDOP, Altitude, Payload Decoder with correct syntax)
- updated to use TinyGPSPlus
