I made a project with a BLE GATT server on ESP32, and a mobile that connects to the device and sending the update using chuncks of the bin files
Do you already have a BT or BLE server in your ESP32 project?

Serial profile may be easiest. Makes it so much easier to test IMHO. How easy would it be to script a file read/bt send vrs some custom protocol? Serial profiles will be well documented. Also it would be a natural hook into the ESP ROM programming routines. Little bit of driver middle & then you would be able to leaver a whole lot of eco.
EDIT: PS The optimum vrs easy argument may be applied. IMHO I have gone 'easy', root of all evil etc.
EDIT: PPS I would not be suprised if there was already a BT OTA solution. Seems a natural Play update mechanism. Google it.
