ESP32-S3 Bluetooth Image transfer

[Douglas-EDM]

Good day,

We're currently using the ESP32-S3 to receive an image to display.
We've set up the ESP32 as a server and receive data from an Android app based on the BLE_UART example in Arduino IDE.
The image is about 300kb and it takes a few minutes to transfer all of the data.

Is there a better way to transmit large files?

Thank you.
