通过蓝牙将Android连接到健康设备

Question

Well im desperately trying to connect my android app to a blood pressure device. I've realized that the amount of examples of this are few . Right now I am stuck at the connection point. It keeps failing with

 12-21 18:00:38.796: E/Connection Failed(2207): java.io.IOException: Service discovery failed

Im following the steps :

1 - getting the default adapter

mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

2 - getting the device

mBluetoothDevice = mBluetoothAdapter.getRemoteDevice(DEVICE_MAC_ADD);

3- creating a socket

mBtSocket = device.createInsecureRfcommSocketToServiceRecord(
                                UUID);

4 - Canceling discovery and connect to device

mBluetoothAdapter.cancelDiscovery();

mBtSocket.connect();

It fails on the connect method with the exception above. Well im kind of lost trying to know why this happens . Im using the UUID 00001101-0000-1000-8000-00805F9B34FB as referenced in other threads. The bluetooth permissions on the manifest are correct. Can someone give me a little help?

Thank you, Pedro Ferreira

If your blood pressure device is compatible with HDP profile, then you can use the health profile supported in android 4.0 to do this job.
