Wifi warnings log output decoding

[AshUK_]

Is there any information on the meaning or decoding of the wifi log messages.

When starting an application you see some obvious debug output:

The majority of the above information output is self explanatory to anyone who has some knowledge of esp wifi chips and 802.11 tech.

I am curious as to what these warnings mean but also on a more general note, is there any documentation provided that helps decode the log output of the wifi module ?

Hello ,
Does anyone know where we can get this info ?
I have my ESP32 board with IDF V4.3 disconnecting randomly from the AP.
I want to debug this issue but can't understand the ESP32 Wi-Fi logs.

Thanks in advance ,

Hello:

I have the same problem. My code works fine on idf v4.2. But on idf v4.3, I get the same new warning messages:

I can't already solve this problem. Could you fix it?

Best regards!

These block ack related messages should probably be at debug log level
