Hi,
I want to build a real secure mesh network without the use of standard protocol or limitation.
I have seen this http://blog.podkalicki.com/esp32-wifi-sniffer/ to receive all packet with the promiscuous mode, i just need to find somthing to send custom packet, now because this work find :).
I have seen this https://github.com/Jeija/esp32free80211 but that was not compatible now, and i didn't find the way to make this work :/
Can some one have a way to send custom packet, and it's better if i can still use promiscuous mode to receive them all :) ?

There is an official API for sending 802.11 frames coming to the SDK in a few days. It has the same limitations as on the 8266 (no management frames) but that should be okay for your use case.

Hi Alterane!

Did you managed to send and receive custom packets?

We're trying to do the same but with last Esp-IDF in promiscuous mode we don't receive DATA packets even though we set filtering.

It looks like filtering function is broken.
