Collect air quality data from public devices

[abitrolly]

Wardriving and collecting data from public data points requires some protocol for acquiring data from such devices. Ideally, such devices should have a signature to be able to distinguish between official nodes and user installed ones.

What is the easiest kind of device discovery is possible for WiFi and Bluetooth networks?

https://github.com/nextgis/nextgislogger/wiki/External-sensors-(Arduino) assumes an explicit pairing, if I understood it right. The question is about alternative broadcast/poll protocol that is open for everyone to read.

we don't collect data from public data points, at least not yet

[abitrolly]

Because there is not protocol, yet. At least no known protocol, so I'd like to create it, so I need some info about ways of IoT discovery.

I have no idea. And I don't quite understand how this became a question to NextGIS Logger.

[abitrolly]

In ideal world logger should be able to collect data from external endpoints that have interesting data. Not only from endpoints that were specifically configured to send data to it. So the question is if this feature (to query nearby air quality sensors etc.) fits NextGIS Logger vision or not?

well, NGL logs data from GSM towers, why not collect from other sources as well
