Arduino

the aprilbeacon is connected to arduino uno.And I have to read a data which updates very fast send by iPhone.Here is the arduino code:

    while(Serial.available())
    {
        readStr=Serial.readString();
        Serial.print(readStr);
        Serial.print("\n");
   }

Only when end updating I can get the data.
Is there any way that can read the data by actual time?

Please try our new firmware v2.1.7 for blueduino.

For firmware v2.1.7

The unit for AT+SDUR (scan duration) is changed from second to ms. For example: AT+SDUR300. the at command will change scan duration to 300ms. You can change the scan duration for faster scan effect. Please also check our iBeaconScan example.
