OTA over BLE

[gomez9656]

Hello there Espressif team!

I have an ESP32 project in ESP-IDF where I need to do OTA using BLE.

So far the examples I have found are for the Arduino framework, but not for ESP-IDF.

Is this supported by default or I'm not looking in the correct place?

Thank a lot in advance

I guess most customers will want to upgrade the firmware via WiFi, so that might be the reason for a missing example.

It's definitely possible though. In my (proprietary) firmware I have implemented OTA over BLE. Since I didn't want to deal with the fragmentation introduced by GATT, I used the L2CAP layer with a connection-oriented channel and a custom binary protocol.

Thanks for the reply!

At least I know I can start working on a custom firmware to do it
