ESP32 Forum

Hello Big Bro,

I am new to the ESP32, I'd like to know directly:
1) Could ESP32-WROOM-32E run any OS on the chip like Ubuntu (like Rasberry Pi)?
2) If I want to change the firmware in ESP32-WROOM-32E by OTA (over-the-air), is it possible? Any link or tutorial?
3) If question 2 is yes, is there any security means during OTA, so that no one can "hack" my ESP32-WROOM-32E devices with the same OTA process?

Hope I am not asking some silly questions and someone who is expert could show me the right way.

Thank you very much for all!

1. No, only small rtos.
2. Yes, many blogs, videos, GitHub projects, and official examples.
3. Usually ota is secured with https and client/server certificates.

1. answered above
2. You may want to check the official documentation (a quick Google search will uncover it) — https://docs.espressif.com/projects/esp ... m/ota.html
3. There is a Secure Boot mechanism on the ESP32 that aids with firmware security for OTA udpates — https://docs.espressif.com/projects/esp ... ot-v2.html. You'll probably need to implement a few other measures as well.
