esp8266 as a wifisniffer

---

Hello,

Is it possible to put the esp8266 in monitor mode and connect the device to the raspberryPI? and receive probereq. from mobile phone’s / ap’s?
And display it in pimatic dashboard?

regards.

well, regarding the core feature of the esp, it’s surely a nice idea.
maybe this would be possible with a wifi sniffer sketch on the esp that either shows up a webpage that can be shown with the iframe plugin or push values of the found wifi from the esp to pimatic either via api, mqtt or however it’s possible.

but this is just my2 cents and not really founded.

Yes, that’s possible. However, depending on what you’re trying to achieve it is perhaps a lot easier to buy a cheap Wifi USB dongle, connect it to the Raspi, and let Raspi do the packet capture using libpcap. If you wish to follow the ESP route though, the following projects look promising to me:

Thanks , I’m going to think about it in the coming weeks…
