[英]Connect to Bluetooth Device via Java Code
I want to connect to another bluetooth device through my laptop's bluetooth. 我想通过笔记本电脑的蓝牙连接到另一个蓝牙设备。
I'm using bluecove library for my reference. 我正在使用bluecove库作为参考。 My environment is as below Machine: Ubuntu 12.4, Quad Core, 8GB Ram. 我的环境如下计算机:Ubuntu 12.4,四核,8GB Ram。 Java: 1.8 Blueove: bluecove-2.1.1-SNAPSHOT.jar, bluecove-gpl-2.1.0.jar Java:1.8 Blueove:bluecove-2.1.1-SNAPSHOT.jar,bluecove-gpl-2.1.0.jar
I have written below code to connect to the local bluetooth device. 我已经编写了以下代码以连接到本地蓝牙设备。
LocalDevice localDevice = LocalDevice.getLocalDevice();
DiscoveryAgent agent = localDevice.getDiscoveryAgent();
agent.startInquiry(DiscoveryAgent.GIAC, listener);
But Im getting below error when I execute this code. 但是我执行此代码时,我遇到了错误。
Native Library bluecove not available

Kindly help me out to get rid this of error. 请帮助我摆脱这种错误。 I have also tried with building native library but it didn't help. 我也尝试过构建本机库,但没有帮助。
I appreciate all your answers. 感谢您的回答。 Thanks. 谢谢。
尝试像这样启动您的JRE: java.exe -Djava.library.path=your_path_to_libbluecove.so ...other options...
这至少应该解决“找不到资源”的问题。
If you use this never released snapshot of BlueCove: BlueCove 2.1.2 如果您使用从未发布过的BlueCove快照: BlueCove 2.1.2
