Update ESP32 Firmware Over USB Serial From Android App

[raymondshi]

Hi there,

I am working on an Android app that is able to connect to an ESP32 device with USB OTA. Now I would like to add some support in the Android app to update the ESP32 device with new firmware version.

I am just wondering if there is anyone who has done similar thing in the past, and would be willing to share the experience.

Thanks in advance
Raymond
