Slow Reading Speed Of Gatt Characteristics Ble

I'm working on a project to transfer data between a Bluetooth device (TI CC2650) and android. To do this, it is necessary to perform a reading of the GATT characteristic at a speed

Solution 1:

The read operation requires one roundtrip per chunk. And the round trip time is at least one multiple of the connection interval.

If you use notifications instead, you can pump such messages very fast since multiple packets can be sent every connection event. Also try increase mtu and use LE data length extention when possible.
