Or setting up some LoRa equipped micro controllers to do sniffing in an area and syncing that data using a LoRa mesh to an active database of some kind. (Like utilize something similar to (or in fact) Meshtastic)

Meshtastic is awesome, everyone go play with it, it's getting more accessible by the day.

There's a lot you can do on the hardware side. A device with three BLE chips supporting the appropriate modes would be able to sniff all three advertising channels at once, greatly increasing acquisition speed. High gain directional antennas would massively increase range. If you were especially squirrelly you could build in a GPS with high precision timing (~$25-100) and geolocate the packets via MLAT (https://en.m.wikipedia.org/wiki/Pseudo-range_multilateration). Moving up to a GPSDO you could start to do things like determine the speed and direction of travel of the sender.

I'd love a community here on lemmy for Meshtastic.

I’d love a community here on lemmy for Meshtastic.

There are two:

/c/meshtastic@mander.xyz
/c/meshtastic@lemmy.ml

Sorry, I should have been more specific. I'd love an active community here on lemmy for Meshtastic. One of those hasn't had a post for 2 months and the other has a single post from an admin and that's it.

yeah, they aren't very active, but (presumably due to federation bugs) there is more there than your instance is showing you: from my perspective the most recent post on the mander community is from one month ago and the lemmy.ml community has three posts including one that isn't from a mod.

you might be able to pull those posts into your instance by searching for their permalinks there (which you can find from the fediverse icons on each post in the web view of those communities on another instance).
