我在使用android 2.3.6的三星Galaxy笔记上遇到蓝牙SPP问题 - 它工作了一段时间但突然连接终止 - 在其他手机上继续工作。这里是日志发生的部分

2 个答案:

答案 0 :(得分：4)

问题是我在没有数据可用的情况下经常进行后续的读取调用。虽然这在大多数手机上运行良好（读取只返回0字节读取） - 这在一些三星手机上失败 - 如果在读取之前确实存在可用数据，则解决方法是通过available（）进行检查。

答案 1 :(得分：0)

我偶然发现了一些细节。这似乎与三星BT堆栈产生的垃圾邮件数量有关。我有一台BT设备，每秒产生~10.5k的数据。当连接到有这个问题的三星设备时，我每秒只能获得大约3k的数据。最终堆栈崩溃了。我知道在Android设备上记录是昂贵的，并且做ligi建议减少堆栈生成的消息量;我认为这是根本原因。

在我的情况下，包裹我正在阅读的流BufferedInputStream似乎已经解决了问题，并让我恢复到10.5 k / s。
