Change MTU size


I'm using my nano 33 BLE as a GATT server (peripheral device), and windows 10 PC as GATT client (central device).

The nano 33 BLE is limiting the MTU size of the BLE link to 23 bytes.

Please help me increase this ( i.e. to 512 bytes ).

Thanks !

Maybe you can refer to "My Documents\Arduino\libraries\ArduinoBLE\src\utility\ATT.cpp"
