Android与RFCOMM设备配对无法连接

标签: android bluetooth connection rfcomm

起初我不得不说,我是android的初学者。我正在开发一款应用程序,该应用程序应通过蓝牙连接到没有任何操作元件(无按钮,无显示)的测量仪器,并接收测量数据。不幸的是,我对测量仪器和制造商也不太了解。我知道的一切是,我必须通过RFCOMM进行通信,当我与android配对时,我必须将序列号作为PIN(09000)发送。 这项工作到目前为止。 Andorid与设备配对。尝试连接时,它首先建立连接,然后在几秒钟后中断连接。我正在使用三星Galaxy S3和HTC Sensation。

在这里,您可以找到我完整的蓝牙连接类:
