No OTA with Arduino-IDE on AI Thinker ESP32-CAM

Is anybody out there who used successfully OTA update on AI Thinker ESP32-CAM
either by Arduino IDE or by OTAwebupdater ?

Thanks for the link, but it does not solve my problem:
I dit it exactly like it is described in the link.
BasicOTA works fine for WEMOS LOLIN 32 but NOT for AI Thinker ESP32-CAM.

Maybe you can get help on a forum dedicated to ESP32.

Thank you, I´ll try it there...
