Wifi disconnect when calling "adc1_get_raw((adc1_channel_t)ADC1_CHANNEL_0);" (IDFGH-4887) #6682

Closed MS71 closed 3 years ago

MS71 commented 3 years ago

Environment

//Detailed problem description goes here. My ESP32-S2 firmware is connecting to my wifi network. I am able to ping the ESP32-S2 from my ubuntu machine. In that moment, when i call the "adc1_get_raw((adc1_channel_t)ADC1_CHANNEL_0)" function, the ESP32-S2 got disconnected from wifi. From that is, i get a ping timeout.

Expected Behavior

ESP32-S2 should stay connected wifi, independent of ADC1.0.

Actual Behavior

Wifi disconnect when ADC1.0 is read.

Another observation, which might related to this. If i compile the code with LOG_DEFAULT_LEVEL_INFO, then i get next exception while executing it.

I am also running into this problem.

Alvin1Zhang commented 3 years ago

Thanks for reporting, we have a fix which is now under internal reviewing, the issue will close automatically once the fix is available on GitHub. Thanks.

MS71 commented 3 years ago

Hi, i can't see the fix on branch:latest. Is this already pushed to github? Maik

lienbacher commented 3 years ago

@Alvin1Zhang this issue is quite a serious breaker. It would be great if this could be pushed real soon. thank you!

william-ferguson-au commented 3 years ago

@Alvin1Zhang I'm still seeing this fault on master v4.3-dev-2136-gb0150615d Has it been merged?

If not, can you give an ETA?

espxiehang commented 3 years ago

Hi @william-ferguson-au ,The fix version of release/v4.3 has not been synchronized to GitHub.

You can test it with cc6bfcd9ac17036824e005f1569df4b66c6415d3 version.

MS71 commented 3 years ago

Hi, the issue is NOT solved with next commit id. Same with master and v4.3 release branch.
