One thing I’m curious about is of using a micro controller with a much larger receiver would extend BLE sniffing capabilities.

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.
