"Hacking" a Bluetooth dartboard

From the date on I created Dutch Darts Revelation, which is more then 20 years ago, I always had the wish to connect it to a real dartboard. With the availability of some relatively cheap electronic bluetooth dartboards, it was time to see if this wish could come true. Last month i bought a Smartness Arcadia 4.0 dartboard and started my journey to "hack" the bluetooth protocol.
