Here we can see, “Establish a Bluetooth Link Between an Arduino & Windows 10 App”

Microsoft’s Developer Network recently published instructions on creating a serial Bluetooth link between an Arduino and a Windows 8.1/10 program so you could communicate basic or sophisticated commands.

You’re in luck if you’re a developer trying to figure out how to create a Bluetooth connection between an Arduino device and a Windows 8.1 program you’re working on because Microsoft just released some important tips on the subject. The tutorial for setting up Bluetooth communication between an Arduino and Windows 8.1 has been shared on the incredibly helpful Channel9. It is available for downloading in C# and C++ (link at the end).

How to create Bluetooth communication between Arduino and Windows 8.1/10

You will need an Arduino with Bluetooth capabilities, such as the Arduino Uno R3, a JY-MCU Bluetooth module, and a Windows 8.1 device with Bluetooth capabilities to test the code. If it doesn’t have Bluetooth built-in, you could alternatively attach a Bluetooth dongle.

As this YouTube video demonstrates, you will then configure the Arduino with a Bluetooth module, two LEDs, and a potentiometer.

Communication with the Bluetooth module is accomplished using the SoftwareSerial.h library. The Windows 8.1 app has to declare Bluetooth serial communication capabilities in Package.appxmanifest: To deploy the Arduino code with VisualMicro, right click the Project in the Solution Explorer and select DebugStart new instance. When the Windows 8.1 app starts, you can establish a connection and control the LEDs.

User Questions

1. How can I use an Arduino to program a Bluetooth module?

Go to Tools in the Arduino IDE, then select Serial Monitor. Set the “line ending” to “Both NL and CR” and the Baud rate to 9600. Without using quotations, type “AT” and press “Send.” If “OK” appears on the Serial Monitor, the module is in AT mode, and you can proceed.

2. How do Arduino and Bluetooth interact?

The Bluetooth module for the Arduino receives the data and transmits it to the Arduino through the TX pin of the Bluetooth module at the other end (connected to the RX pin of the Arduino). The received data is compared and checked by the code that was uploaded to Arduino. The LED illuminates if the received data is 1.

3. Why is my Arduino not able to connect to my computer?

Ensure your board is turned on (green LED should be lit) and linked to the computer first. It’s possible that the USB hub won’t work with the Arduino Uno and Mega 2560. Instead, connect the board directly to your computer and restart the Arduino IDE if nothing appears in the “Tools > Serial Port” menu.
