Hello,
Help me please, I have an issue with ATT MTU size.
When connecting Android (BLE client) to nrf52 (server) and ATT MTU is 20 bytes in max.
I have changed on ATT MTU on nrf52, but still have 20 bytes.
I see this topic:
https://devzone.nordicsemi.com/f/nordic-q-a/18544/the-maximum-byte-can-received-per-package-used-nordic-uart-android-app/71568#71568
Is it a way to check, does current mobile phone support more 20 bytes payload?
