I'm confuse .....
What do I really need to install in order to use the API for bluetooth?
I'm going to develope a wireless mobile application that can communicate with my laptop....

No need to install anything..just add the Bluetooth libraries that you are going to use to your classpath(if you are using IDE's , then add the external bluetooth jar files to your project). Thats all...you are done..

Thank you for your reply...

this jar files, I came to Antinav and BlueCove...
is the Java JDK not enough ?

sorry for this late reply....
