Bleutooth State Exception - Where does it come from?

[vadikv]

When I run the following code on my Nokia 6682, it throws a BluetoothStateException:

                        // Called when a new device has been discovered

                        public void deviceDiscovered(RemoteDevice remote, DeviceClass devclass)

                        {

                                    try

                                    {

                                                System.out.println("DD: " + remote.getFriendlyName(false) + " at " + remote.getBluetoothAddress());

                                                Log.append("Found device: " + remote.getFriendlyName(false) + " at " + remote.getBluetoothAddress(), null);

                                                

                                                if(remote.getFriendlyName(false).equals(devicename))

                                                {

                                                            foundDevice = true;

                                                            agent.cancelInquiry(this);

                                                            Log.append("SSS: " + remote.getFriendlyName(false) + " at " + remote.getBluetoothAddress(), null);

                                                            agent.searchServices( null, new javax.bluetooth.UUID[]{ new javax.bluetooth.UUID(0x0100)  }, remote, this);

                                                }

                                    }

                                    catch(BluetoothStateException e)

                                    {

                                                Log.append("BSE while SS TEST", null);

                                    }

All this code does is search for services with UUID 0x0100 on a device with a given device name. Why does it throw this exception and how can I fix it?

If you can please cc responses to vargasv@msoe.edu

Thanks much.

Hi vadikv,

After the check for the device name is passed, you have called agent.cancelInquiry(). Soon after that you are asking the Discovery agent to start a searchServices(). I think this is causing the problem. Make sure that the device discovery is complete and the Inquiry status become cancelled or a callback is got before you issue a call to searchServices().

Just give it a try.
