Thank you for your interest in the Intel® Curie™ Board.
This type of inquiries are out of the scope of this technical support team, since we focus on issues related to the Curie module itself.
The adequate assistance is provided by the Arduino community, and I saw that you already posted your question there (http://forum.arduino.cc/index.php?topic=507213.0).
As stated in this article https://www.dfrobot.com/blog-675.html, you’ll probably need to include the BLESerial.h library (https://github.com/sandeepmistry/arduino-BLEPeripheral/blob/master/examples/serial/BLESerial.h).
Please note that in the comment section of that article, Martin mentions the following:
You can only communicate by serial using the monitor or plotter (like send AT commands and read values sent from other devices).
If you have any update or another question related to the Curie module itself, don’t hesitate to contact us.
Have a nice day.
