ESP32 Transfer file Using BLUETOOTH

I have esp32 module ,tested bluetooth connectivity its work.

and also transmit string using android mobile via bluetooth to esp32.

How can i transmit a file to ESP32 using bluetooth and How to store that file to SPIFFS??

Thanks.

One can use the ESP32's documentation, the ESP32 API API Reference - ESP32 - — ESP-IDF Programming Guide latest documentation as a source of information.

Do note that with BT, and SPIFF's enabled getting the correct partition scheme will be important.
