Error in Bluetooth Device Discovery
提问by Ranveer
I tried the following code for discovering a bluetooth device
我尝试了以下代码来发现蓝牙设备

while coding in eclipse. I am using bluecove 2.1.0 and a 64-bit version of Windows 8.
在 Eclipse 中编码时。我使用的是 bluecove 2.1.0 和 64 位版本的 Windows 8。
Can anyone please suggest me a fix?
任何人都可以建议我修复吗？

There is even a newer version: http://snapshot.bluecove.org/distribution/download/2.1.1-SNAPSHOT/2.1.1-SNAPSHOT.63/
甚至还有更新的版本：http: //snapshot.bluecove.org/distribution/download/2.1.1-SNAPSHOT/2.1.1-SNAPSHOT.63/
Also, it's important to note that this replacesany other bluecove jar. Because the message indicated missing libraries, I initially addedthis, and it caused a version conflict.
此外，重要的是要注意这会替换任何其他 bluecove jar。因为消息指出缺少库，所以我最初添加了这个，它导致了版本冲突。

Actually the JAR you have added does not contains x64 dll. Download the JAR from the below link and use it. It worked for me. http://www.java2s.com/Code/Jar/b/Downloadbluecove211jar.htm
实际上，您添加的 JAR 不包含 x64 dll。从以下链接下载 JAR 并使用它。它对我有用。 http://www.java2s.com/Code/Jar/b/Downloadbluecove211jar.htm
