In the end I solved this issue by disabling the UART over USB port and putting compiling options to performance. So definitely some timing issues.

I thought I got NTP and HTTP server running together stable, so I moved on to MQTT, but as soon as the MQTT service is trying to connect to t...

There were different things going wrong in my code. It was easier to put the Wifi driver in APSTA mode. Then you can use Wifi connect / disconnect for connecting with the access point for station mode while the ESP32 soft AP remains active. Then running the http server will just work normally instea...

When I'm running my ESP32-S2 in Access Point (AP) mode with a fixed IP and the ESP IDF http server running, I am able to connect to the server (port 80). However, I made the application such that I can change to station mode (STA), stop the http server, restart the wifi and start the server again. A...

That worked! Many thanks!

I'm trying to use GPIO 39 as an output to drive an LED. I know on the ESP32 WROOM that's not possible, but it should be possible on the ESP32-S2. However, the output remains low. gpio_set_direction(39, GPIO_MODE_OUTPUT); gpio_set_level(39, HIGH); What can I do? Is it conflicting with jtag (since IO3...
