Add "Adafruit BluefruitLE nRF51" over the libary manager in the Arduino IDE https://github.com/adafruit/Adafruit_BluefruitLE_nRF51

Create a new entry with the type of "string value" and call it "ShellExecute". This new value should contain the command which should be executed when the bell is pressed. In our case a powershell script. Example:

mshta vbscript:Execute("CreateObject(""Wscript.Shell"").Run ""powershell -NoLogo -noninteractive -Command """"& 'M:\scripts\notify.ps1'"""""", 0 : window.close")
