I am using BLE to communicate with my Arduino Nano IoT 33.
I declared my SctringCharacteristic with the size of 200.
BLEStringCharacteristic stringCharacteristic(CHARACTERISTIC_UUID, BLERead | BLEWrite, 200);
However if I send a string longer than 20 bytes the Arduino stops responding. I assume it is because of the default MTU size of 23 bytes.
Is there a way to increase MTU on this model to be more than 23 bytes? I know one can do it on ESP32,
but I cannot find the way for Arduino.
