Resume an OTA update on ESP32

[mmurty]

Hi All,
I am trying to implement OTA on ESP32 using the OTA API provided in ESP-IDF V4.3.
The firmware image is transferred over the GSM network.
I see that the

Code: Select all

esp_ota_begin()

API erases the complete flash when called.
I want to support resume of firmware updates as my communication medium is unreliable.
Please let me know how to implement this.
