Where to define dataSending?

Re: BLE: sending data to device

void BLESerialDevice::writeData(const QByteArray& data) {
int i = 0;
while (true) {
dataSending = data.mid(i, 20);

    if (dataSending.isEmpty()) break;

    m_service->writeCharacteristic(writeCharacteristic, dataSending, QLowEnergyService::WriteWithResponse); 

    i += 20;
};

}

@Zhang_Yubiao What is your exact question?

assuming you mean "declare", then right where it is... minimize variable scope.
