In this example we are going to create a simple C# windows form application to communicate with BleuIO using SerialPort. This script can be used to create Bluetooth Low Energy application using C# with BleuIO. We will have buttons that connects and disconnects from BleuIO. An input field that takes AT commands from the user and sends it to BleuIO using SerialPort. And a text area will display the response from BleuIO to the screen. Here is a demo of this sample app. https://www.youtube.com/watch?v=eXJJXSXjzHI Source Code : https://github.com/smart-sensor-devices-ab/bluetooth_low_energy_csharp_WFA.git Read full article at https://www.bleuio.com/blog/details.php?id=1433&title=C#-desktop-application-to-connect-to-BLE-devices-using-BleuIO
