Basic code to use the pytrack board and a LoPy (will potentially also work with the Fipy). If a µSD card is present it will also log co-ordinates to file.
Some output is printed to the console otherwise the RGB LED is used to show various states
| Colour | Type | When | Meaning |
|---|---|---|---|
| Yellow | Flash | Boot | SD card Mounted |
| Red | Steady | Anytime | No GPS Lock |
| Blue | Flash | Anytime | Search for LoRaWAN |
| Blue | Steady | Anytime | Joined LoRaWAN network |
| Yellow | Flash | Anytime | Written to file |
| Green | Flash | Anytime | Sent LoRaWAN message |
| Red | Double Flash | Anytime | Write to SD card failed |
Multiple LEDs can be lit at the same time so Purple means on LoRaWAN network but no GPS.
Utilities to recieve MQTT messages and display / record into mongo database for later analysis.
