How do I use BlueCove to use Bluetooth on a MacBook with Java?

Question

I would like to implement an Java application that uses Bluetooth on my MacBook Air laptop. I try to use the Java bluetooth library BlueCove.

I tried to implement the first example DeviceDiscovery but it throws an BluetoothStateException with the message: BlueCove library bluecove not available. I have added bluecove-2.1.0.jar to my Build Path in Eclipse.

What is the problem? How can I use BlueCove with my MacBook Air?

Answer 1

BlueCove requires the 32-bit JVM to run. Adding the -d32 argument to java to force the 32-bit JVM will fix the problem. You can do this in Eclipse under VM Arguments for the launch configuration.

It's worth noting that this problem will occur under Windows as well. The -d32 trick works there, too. – Muscadel

Eclipse says : This Java instance does not support a 32-bit JVM – Aitchbone
