After PWM ledcWrite GPIO is blocked for normal IO-use

Hi! The "Ai Thinker ESP32-CAM" board uses GPIO_4 to control the flash-LED. I use PWM to dim the flash-LED to less brightnes for some time: ledcWrite(channel, dutycycle) This works fine. After that I want to switch on the flash-LED by digitalWrite(GPIO_4, LOW) and to switch off by digitalWrite(GPIO_4...

Re: OTA does not work on AI Thinker ESP32-CAM board

Thank You, Erkiman!
I did exactly what You proposed and now BasicOTA works perfect on Ai Thinker ESP32-CAM board !
Because I always like to understand what I´m doing: could You explain that new line in "boards.txt" or give a link to the source of that information?

Does anybody know about a difference between the 2 components? The OTA upload is not interrupted ...

OTA does not work on AI Thinker ESP32-CAM board

Hi, I am new in this Forum an hope to find someone who runs successfully OTA on AI Thinker ESP32-CAM board. My code should not be wrong: I use "BasicOTA" of the examples in Arduino-IDE. With that code OTA works perfect on "WEMOS Lolin 32" board. But NOT on "AI Thinker ESP32-CAM" board. Compiling via...
