I would like to know the purpose of programming in C # on a Windows Form application. How can activate a buzzer sound on BTool. My application is that when I press a button on the application, the buzzer will sound.

    Hello Perot,

    You can use any language to program your Windows Application Form, Java, HTML5, C, C++, whichever software you are comfortable with..  C# is free and powerful enough to do all you need.  You can use the Thermometer example as a guide.

    The buzzer or Proximity Alert has a service UUID:1802 and a Characteristic UUID:2A06.  The characteristic Value Handle in my case is 0x0028. If you write a 1 or 2 to this handle, you will trigger the buzzer.  Writing a 0 turns it off.  You can find this information by going to the Adv. Command tab in Btool 1.3 then expand GATT and select GATT_DiscAllCharDescs and then Send Command.  It shows the UUID,Handle and Description of everything available on your device.

    You can find all this information in the CC2540/41 Software Developer's Guide v1.3, SWRU271D

    Thanks,
