Hello everyone. I am building a Bluetooth based application using Android. To debug the application I am using these two devices:
-Nexus S -LG P500 Following the Documentation on the Android Web Site: http://developer.android.com/guide/topics/wireless/bluetooth.html I have built a server and a client module. When trying to connect to the devices I am using the following routine: Server: mServerSocket = mBluetoothAdapter .listenUsingRfcommWithServiceRecord("app", CTRLUUID); mDeviceSocket = mServerSocket.accept(); Client: mServerSocket = d.createRfcommSocketToServiceRecord(CTRLUUID); mServerSocket.connect(); In certain cases I am able to interconnect the two devices. During development in the past two weeks I repeatedly ran into the following IOexception when connection from the client: "Service discovery failed" Although my Server side is accepting the connection. I already found posts discussing similar problems although never in the form of an "Android to Android" application. What I noticed was the following behaviour: If I start the server and wait a few seconds until I try to connect with the client, chances are very high the connection is established. I suspect, that if my continually tries to connect to an offline server, the service discovery table somewhere caches the result and does not really "look" for a new server the next time it tries to connect. I tried to find a workaround for about a week now and am left with adding a "Thread.sleep(10000)" before retrying to connect - which is not really a solution. Has anyone else been experiencing similar issues? Thanks in advance! Manuel -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
