Experimental Helium IoT coverage mapping device, coded in Arduino running on Seeed Studio T1000-E LoRaWAN GPS tracker.
This software turns a T1000-E into a custom OpenSource Helium mapping device. It sends the current GPS location via Helium LoRaWAN to community projects like
The LoRaWAN uplink payload decoder works only on ChirpStack-based LNS (LoRaWAN Network Server), and at the moment not all community projects can handle those uplink metadata... Attention: There are different types of similar Seeed Studio T1000 devices:
- T1000-A =>closed source GPS tracker for LoRaWAN, contains multiple sensors
- T1000-B =>same device as -A , just without sensors
- T1000-E =>similar to -A , but OpenSource for custom LoRa-Peer-to-Peer projects (like Meshtastic) and custom LoRaWAN applications
This code is based on Seeed Studio's T1000-E Arduino example code and contains code snippets from many sources...
It's an experiment for proof-of-concept, as a starting point for other developers :-)
The Arduino code shows joining LoRaWAN network with custom OTAA-keys, extracting GPS location from GNSS chip, sending payload encoded with CayenneLPP as LoRaWAN uplink, a blinking LED as a test for minimal user interface, handling of short/long/double button press on button, and using buzzer for playing Nokia phone ringtone and Star Wars theme... All these functions are executed quasi-parallel with ProtoThreads 😎
