I am able to send a file successfully from a Trimble GeoXT 2005 (Windows Mobile 5) to a Trimble Nomad (Windows Mobile 6) using the Obex Listener. I need to trigger an event on one unit based on a command from the other unit. I a have assumed that I must use the BluetoothService.SerialPort to send a command. I cannot connect to the serial port service. I continue to get the "Connection Actively Refused...". I have seen this error quoted many times in the forums, but have never seen it resolved. I have tried SetPin and PairRequest in my latest attempt and nothing seems to have any effect. What am I missing here? Is this a code problem or a hardware driver config issue? First Unit serialep = new BluetoothEndPoint(this.m_BTDevice.DeviceAddress, BluetoothService.SerialPort); client = new BluetoothClient(); BluetoothSecurity.PairRequest(this.m_BTDevice.DeviceAddress,"1234"); client.Connect(this.m_BTDevice.DeviceAddress, BluetoothService.SerialPort); Second Unit serialep = new BluetoothEndPoint(this.m_BTDevice.DeviceAddress, BluetoothService.SerialPort); client = new BluetoothClient(); BluetoothSecurity.SetPin(this.m_BTDevice.DeviceAddress,"1234"); client.Connect(this.m_BTDevice.DeviceAddress, BluetoothService.SerialPort);

For a custom service connection between two programs, see the "General Bluetooth connections" section in the user guide.  One device running a BluetoothListener and the other a BluetoothClient.  Use a custom Service Class ID, like the below, which is then used by server and client. :-)

If you need any more explanation let us know.

I just tried using the BluetoothListener (server and client) on my 2 mobile devices. I still get the connection actively refused error. Only the Obex library connects and passes files. Whats different between the Obex library and the InTheHand library? Can I use the Obex server on each mobile device and pass commands and files both ways between devices? Thanks.

What Obex library?  Our ObexWebRequest?  The OBEX server does the equivalent of "new BluetoothListener(BluetoothService.ObexObjectPush)" and the client does "btCli.Connect(addr, BluetoothService.ObexObjectPush)".  If a client tries to connect to a service that's not active then the 'connection refused' error will occur.  So I guess there's still something wrong with the BluetoothListener in your case.

You can use OBEX if it suits the scenario.  If using the built-in server then the user has to accept the transfer.  If you stop the built-in server and use our ObexListener class then the normal transfer functionality will be lost.

I guess that I wasn't using Brecham.Obex for anything. I was using the InTheHand.Net.ObexWebRequest / ObexWebResponse to send a file from one pda to another running the InTheHand.Net.ObexListener. This would successfully send a file without prompting to accept the file. I just could never get the SerialPort or Custom Service to accept a connection in order to "trigger" the sending of the file. No matter what I tried I would always get the connection actively refused error. Only the InTheHand.Net.ObexListener scenario would work. Robert McLaurine
