我正在尝试编写一个与ELM327（BT）通信的简单应用程序（类似于BluetoothChat示例）。
Torque（众所周知的Android OBD应用程序）能够连接OK - 它是唯一的一个。我的测试应用程序，SENA BTerm和android-obd-reader（着名的开源OBD应用程序）都无法连接。
我正在使用着名的服务UUID 00001101-0000-1000-8000-00805f9b34fb
当日志显示ACL_CONNECTED事件时，我的代码（和android-obd-reader）抛出一个IOException，说“套接字关闭或超时”。
这些是我在调用connect后运行测试的日志。

有任何解释吗？我会把它归结为一个坏的适配器，除了Torque工作
