If the button appears as a keybaord and sends key events, you cna use [key]. Otherwise, I’d write a script (in python maybe) that would read the button using something like the bluez library and forward events to pd using a network socket.

Hi,  I'd like to know if anyone out there has ever used a Bluetooth button to remotely control pd. I would like to use several of those on a theatre set to trigger individual sounds. 
Thank you.
