Re: ESP32-CAM (ESP32-S)

It might be broken. One other potential explanation for that screen is that you hit the reset button when the ESP32 was already being written to.

Re: Wifi disconnects

Hi gerardbos, Would you be able to provide some of your code? Especially the code which handles WiFi connectivity When I was starting, to get wifi up and running, I personally found that the easiest way was to start with the example_connect function from https://github.com/espressif/esp-idf/blob/mas...

Re: Preserving error information between reboots with RTC_NOINIT_ATTR

This information is stored through RTC RAM. Here is a bare bones, simple proof of concept to provide a starting point for you. I have mad...

Re: ESP-IDF 4.2 resetting WiFi SSID and PASSWORD set previously in menuconfig

Martin, Another option is to simply edit the WiFi username and password in the sdkconfig file (be sure to edit plain sdkconfig, not sdkconfig.ci or similar). If you are simply plugging into example_connect() from the examples to obtain a WiFi connection, you will then need to change the following li...
