ESP8266 sniffer sample

[azarubkin]

Hello,

I'm trying to compile a simple packet sniffer. I took it here: https://github.com/davruet/esp8266-sniffer. I've compiled it with SDK 1.3.0 succesfully (using esp-open-sdk). However, after flashing it just hops from one channel to the next one, and does not display any captured packets.

I have Wi-Fi router installed in the same room, so there should be some output. I switched the router to b/g mode without encryption, but got no result.

Do you have any ideas why the code does not work? Do you have a working sample code for sniffer?

Any help would be appreciated.

Okay, after contacting Espressif they emailed me the sources for sniffer example which works with SDK 1.3.0.

https://github.com/pulkin/esp8266-injection-example

Requires SDK 1.4.0. Enjoy!

Hello, pulkin.

Great work! Thank you for share with us.

I tested your code and sniffer capability worked very well. But in injection tests, I had no success unfortunately. When I check the value of parameter returned by the "wifi_send_pkt_freedom" function, it is always negative (-1), so, failed to send. I'm using SDK 1.4.0.

Could you help me?

Thank you so much.
