im working on a simple patch for a norwegian museum, where there is a question whether i can send information fra pd to a bluetooth device (in this case, a cellphone). in short the patch lets users create their own "ringtones", which is stored in a table, and i want them to be able to send this to their own cellphone. i have no experience or knowlegde of bluetooth what so ever, and im working on a tight schedule, so i thought id ask here first....

If you have a bluetooth driver on your computer then you can set the audio output device to bluetooth. Still, you need a cellular phone that will record ringtones from bluetooth.

Here's a nice link on using bluetooth with an ardunio interface.

and you can talk to a bluetooth adaptor, though as this thread will show you it's a low level
thing
