site_archiver@lists.apple.com Delivered-To: bluetooth-dev@lists.apple.com Hello, I tried to establish a RFCOMM serial profile to a Symbian S60 phone that is running a chat application. I am programming in C. I can obtain the device and do an SDP query on it. Then I am using the following code to find the RFCOMM channel id: IOBluetoothSDPServiceRecordRef service; IOBluetoothSDPUUIDRef sppServiceUUID = IOBluetoothSDPUUIDCreateUUID16(kBluetoothSDPUUID16ServiceClassSerialPort); service = IOBluetoothDeviceGetServiceRecordForUUID(device, sppServiceUUID); IOReturn ret; ret = IOBluetoothSDPServiceRecordGetRFCOMMChannelID(service,&channelID)); ret = IOBluetoothDeviceOpenConnection(device, nil, nil); ret = IOBluetoothDeviceOpenRFCOMMChannelSync(device, &chan, channelID, myEventListener, (void *)self); And that last function call fails and sets device to 0. I don't know what to do because the channelID number is definitely correct. Could someone please help me out? Thanks -- Psssst! Schon vom neuen GMX MultiMessenger gehört?
