Does the OTA process of ESP32S3 support saving the flashing progress, and can it resume the OTA process from the previous position after power-off and restart?

For example, if there are 20 frames of OTA data to be transmitted, and 10 frames of data have been transmitted and flashed successfully through the esp_ota_write() function, can ESP32 start transmitting from the 11th frame after restarting and continue the OTA process?

Hello @chaoaaaa
At the moment, the OTA resumption across reboots/power-off is not supported in ESP-IDF. However, I want to assure you that it's in our plans, and we will have it implemented it in near future.
