hello, although I suppose you have already thought about it, an alternative way is that the app installed on the client's smarphone, configure the phone as AP wifi with some keys that ESP knows and pressing, for example, the reset of ESP this connects to the smartphone and updates.
Greetings,
ESP32 OTA via BLE
Re: ESP32 OTA via BLE
hi folks,
we tried implementing OTA over BLE ( product requirement), 700KB taking around 52 minutes .. roughly 200 bytes per second with long write.
could anyone advise what could possibly wrong.. we built data transfer rate over the gattt_server example code.
i see in the websites that we could hit upto 2K with BLE, any one could explain how to get that rates?
ios is not allowing write without response. please help me folks, we are in a dire need to speed up with data rates.

Resolved by changing the MTU to 500 from client

Re: ESP32 OTA via BLE
Also try making your connection interval shorter. this may improve the transfer time.
Out of curiosity approximately what is the update time once you increased the MTU to 500?
