1. Intro
The plan is to use Meshtastic to transfer citizen science measurement data.
Stuff to figure out:
- network coverage: meshnet map
- do nodes forward packets that do not belong to their "own" network? -> appears to be so!
2. Protocol
See https://meshtastic.org/docs/overview/mesh-algo/
Quick links:
- Port number: https://buf.build/meshtastic/protobufs/docs/main:meshtastic#meshtastic.PortNum
- MQTT topic organization: https://meshtastic.org/docs/software/integrations/mqtt/#mqtt-topics
3. Hardware
Nice antenna? https://nl.aliexpress.com/item/1005007301116616.html
4. MQTT
In the netherlands, data is typically sent to the 'boreft' MQTT server, for example
mosquitto_sub -h mqtt.meshnet.nl -u boreft -P meshboreft -t "#" -v
Examples of typical data:
