I've wondered about how to do something useful with these probe events.

A while ago, I tried to trigger some actions at home, depending on the presence of family members, by regularly pinging their cell phone.
Unfortunately those devices won't always reply to ping.

Yesterday, I succesfully tested QuickFix's sketch (many thanks for sharing ) and I think it's definitively the way to go to reach my goal.

Now, I have to test it in AP_STA mode, cause I want to forward events to my MQTT server.

Would love to see (parts of) the result.

I was thinking/fantasizing about writing probe-requests to SD-card, to have an isolated spy device I can leave hidden at places.
If I would place a dozen of these in, lets say, a shopping mall, I should be able to make some sort of device tracking using triangulation.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

My first try:

Next steps: do the mapping with known devices and store the data in my database, with Node-RED, and decide if all this stuff can be of any interest.

My first try:

Great, this will also be a nice way for me of learning C++.

Thanks!
