Unable to connect bluetooth to Arduino Uno + nrf8001

Need Help With My Project
1

Hi Everyone!!

I’m attempting to connect Blynk to my Arduino Uno with Adafruit nRF8001 breakout board

The code below is the standard nRF8001 code in the blynk examples

Code compiles and uploads to the board although when i try and find the device using the Bluetooth widget in the Blynk app it fails to recognise a device

Ive succesfully attempted to connect to the arduino using the default Adafruit example and Adafruit app

Any help would be very much appreciated

Many thanks

• Hardware model + communication type: Arduino UNO with nRF8001
• Smartphone IOS
• Blynk Library version : V0.5.2

  Serial.println("Waiting for connections...");

  Blynk.begin(SerialBLE, auth);

void loop()

  SerialBLE.poll();

  if (SerialBLE) {    // If BLE is connected...
    Blynk.run();
  }
}

Another thing,

If i use the code from the online Blynk example builder, i get the following error:

no matching function for call to 'BLESerial::BLESerial(int, int, int)'

  You’ll need:
   - Blynk App (download from AppStore or Google Play)
   - Arduino Uno board
   - Decide how to connect to Blynk
     (USB, Ethernet, Wi-Fi, Bluetooth, ...)

  There is a bunch of great example sketches included to show you how to get
  started. Think of them as LEGO bricks  and combine them as you wish.
  For example, take the Ethernet Shield sketch and combine it with the
  Servo example, or choose a USB sketch and add a code from SendData
  example.
