wifi long running connection break (IDFGH-6226)

[achao1104]

Hello,

idf:4.3.1 and module:esp32s2

We used a camera to connect esp32s2 by wifi, it worked, but after a couple of hours, the connection will break, but if the camera connects huawei wifi, it can run for long time without any issue.

Can you think of any reason about it?
Thanks,
Peter

Hi @achao1104, we cannot get enough info from your current description.
Please provide more info, for example, but not limited to:

1. The recurrence steps and the rate of the issue
2. logs, best to be as complete as possible

we only have dump log, plese take a look below.

Hi @achao1104
From your core dump log, we only get that there are some operation in WiFi will cause the stack corruption, but lack of more details in the backtrace, it's hard for us to debug. Can you config the IDF Log level to Debug level, it will show more logs.
And what the camera is? And what operation when the camera connect to ESP32-S2 SoftAP?
Thanks.

[jack0c]

@achao1104 again have you use ADC in your project? please use latest v4.3 and try again.

[Alvin1Zhang]

Thanks for reporting, feel free to reopen if the issue still happens. Thanks.
