Hello,

I have a device that I am trying to communicate with from my BlackBerry using Bluetooth.

I am able to connect to it using the method Connector.open(info, Connector.READ_WRITE );

I can also read and write using the input and output streams. 

However I need to be able to detect when the port is disconnected from the remote device. I was thinking of using BluetoothSerialPortListener. To use this I try to connect to the device using this method:

listener = new MyBluetoothListener();  

_serialPort = new BluetoothSerialPort(info[i].toString(), BluetoothSerialPort.BAUD_9600, BluetoothSerialPort.DATA_FORMAT_DATA_BITS_8 | BluetoothSerialPort.DATA_FORMAT_PARITY_NONE | BluetoothSerialPort.DATA_FORMAT_STOP_BITS_1, BluetoothSerialPort.FLOW_CONTROL_NONE, 2048, 2048, listener); 

This does not appear to be working. The above call works fine and I don't get any exceptions. However, I also don't get the deviceConnected() callback in my listener.

In the console output I see the following and nothing else after this:

BT: allocSerialPort 81159234
BT: sdpAddRecord
BT: allocSdpAttributeData

Is there something I'm missing here?  

To summarize, I have two questions:

1. Why isn't the connection using BluetoothSerialPort working?

2. Assuming I can't get that to work is there a way I can detect a disconnect when using the Connector.open() method? 

Thanks in advance for your help.

I am connecting to a Bluetooth device using very similar code to yours, with two exceptions:

1) You use info[i].toString(), as the first parameter, I just use the equivalent of info[i]

2) I'm using BluetoothSerialPort.BAUD_115200,

The listener receives disconnections as I would expect.

The messages I see when debugging this re as follows:

BT: allocSerialPort 814ee52c
BT: BTEVENT_LINK_CONNECT_CNF
net.rim.bluetooth: DC00
BT: BTEVENT_LINK_POLICY_CHNG received
net.rim.bluetooth: EC00

This test was run on an 8900 running 4.6.1.199.

Hope this helps.

Thank you for the response. That fixed my problem.

I removed the .toString() and used just info[i] and everything works fine now.

I can connect and my listener is getting the callbacks.  

Thanks.

HI,

I Need help on Blackberry Bluetooth Connectivity for sending/receiving audio Data to/from connected devices. If you have any information regarding that , Please guide me.

I want to share my already playing music to other bluetooth enable device using coding.

I tried for RIM API BluetoothSerialPort  and BluetoothSerialPortInfo but could not get success.

Thanks & Regards
