How to send data from a P-Nucleo-WB55 board to a custom made android app?

[CFrag.1]

Howdy,

I'm new to embedded systems and really new on BLE.

I started with the BLE_Custom project and made it discoverable by using a fixed pin, bonding mode on, making the IO Capability to no input, no output and no MITM protection to see the device and connect from my android. Now what i want to do is to send images and commands from the phone and the board. but i don't know where to start. i know the images we want to take is around 640x480 pixels and it would be send to the phone in 10 frames per second. Is it possible to send such files via BLE

Assuming 1 byte/pixel, this is 480*640*1byte*10Hz = 24.6 MBps.

A quick google search shows BLE is around 2.5 kBps.

Clearly not going to work here.
