As I told someone some days ago I am working in a new use of bluetooth technologies in mobiles phones and handled devices. As first step I am collecting as much information about different bluetooth stack implementations, programming interfaces on severals OSs (mainly windows, linux and *BSD). I am using this entry to write down all useful URLs I find on Internet.

Bluetooth programming with sockets in Windows
Slides on Bluetooth programming in Linux
