No response value for long commands.

MTU is set to maximum.

          String? foundDeviceId = await storage.read(key: DEVICE_ID);

          String dataToSend =

          List<int> dataBytes = utf8.encode(dataToSend);
          for (int i = 0; i < dataBytes.length; i += 16) {
            int end = i + 16 < dataBytes.length ? i + 16 : dataBytes.length;
            List<int> chunk = dataBytes.sublist(i, end);

            final characteristic = QualifiedCharacteristic(
              serviceId: Uuid.parse('6E400000-B5A3-F393-E0A9-E50E24DCCA9E'),
              characteristicId:
                  Uuid.parse('6E400002-B5A3-F393-E0A9-E50E24DCCA9E'),
              deviceId: foundDeviceId!,
            );

            flutterReactiveBle.writeCharacteristicWithResponse(
                characteristic,
                value: chunk);
          }

Since the Bluetooth device can read 16 bytes at a time, I implemented it like the code above. However, no response value comes.

I don't think this is library issue, please check your device
