Re: WiFi AP disappeared suddenly while using HTTP Server


I had the same issue, and
it was solved by calling "yield();" or "taskYIELD();" in webserver' handlers and every place in code where long work may be. "taskYIELD();" say to scheduler to switch work from your code to some other task, and specially WiFi, for short period of time. Otherwise if your ...

Re: How to change channel for WiFi AP into ESP32



Yes for AP+STA the channel will be the same and STA channel has to match the AP the station is connecting to.


why have they set a AP channel config if it is bound to pick it up from STA directly. Can someone help here? We are trying to use esp32c5 as a bridge between 5GHz router and a 2.4GHz ...

Re: DNS lookup failed err=202 res=0x0



202 is EAI_FAIL, which is a general permanent failure. Are you sure WiFi is up and running? If so, can you maybe do a packet dump using Wireshark or something?


Sorry to dredge up such an old post, but the info you provided is still 100% useful 5+ years later.

Re: ESP32 connects to Access Point but can't get IP address


I've discovered there can be an issue with the antenna on the esp32s3 devkit c (at least with some of the clones). Try putting your finger on the antenna & see if it solves the problem. My board would connect out of the enclosure but not in the enclosure when the antenna was close to other parts ...

Re: Disable Bluetooth error



This may be a bit late, but I found this issue after positing my own thread on this topic. This seems to happen when you try to disable the bluetooth in its own thread (IE, in the gatt callback or something). You basically end up with a deadlock. I worked around it using https://www.freertos.org ...
