Hello,
I’ve enforced OTA on ESP32 through WiFi by setting up server on ESP32, and likewise through WiFi by using http.

Now I want to do OTA with http but through GSM network.

I’ve enforced ESP32 SIM800L module communication to the pall, so my GSM connection is good.

Can any bone please let me know of an illustration for OTA on ESP32 through GSM?

Thankyou.

    There's no difference between doing it through GSM or wifi or ethernet, any http functions including OTA will just use whatever interface is configured. You should just have to run esp_https_ota( & config) nearly in your app and it'll work.

Can a .bin compiled/uploaded to an ESP32 from an android?

I like to connect my android tablet to an ESP32 via a USB cable (type C on the android side, and USB micro on ESP32 side,) compile a program and upload the result to the ESP32.

I have a separate power supply to the ESP32 using the Vin pin, so power from the android is not needed.

I understand and have used OTA from a laptop, I guess OTA from android might work too (any insight here would be nice, thanks,) but if I hose the code, OTA won’t work and USB will be needed to recover.

    The ESP-IDF codebase plus toolchain are available in ARM Linux flavour, so you could possibly try installing them in a chroot on the tablet. You can install Arduino as an ESP-IDF subcomponent as well if you want to use that API.

    1. Example of OTA testing "esp-idf /examples/ system/ota " ? 2. Please use the simple_ota_example(In ESP-IDF) to test over "HTTP  Server" for OTA. You can refer to the "ESP32 HTTP OTA test " guide .
