One thing that puzzles me: When communicating with the Toshiba stack I get an event in my callback that I don't see from any other bt stack: kIOBluetoothRFCOMMChannelEventTypeControlSignalsChanged: signals (like DTR, CTR) changed. (not yet supported) Does anyone know what this means or what it implies trying to communicate with this device??? This email sent to site_archiver(a)lists.apple.com

Perhaps that's the problem. Apparently not; the documentation implies you have to do both, and if I don't try to call IOBluetoothDeviceOpenConnection() first, IOBluetoothDeviceOpenRFCOMMChannelSync() just returns kIOReturnNotOpen - meaning device not open. Unless it means I have to wait for it to open itself - which doesn't seem to happen in my tests - its difficult to see whats inappropriate about calling IOBluetoothDeviceOpenConnection(). Its supposed to open the baseband connection, and that did close. And it does eventually work, is just that after that IOBluetoothDeviceOpenRFCOMMChannelSync() goes into a snit. I am beginning to wonder if my device is misbehaving in some way, although the BT stacks reaction seems a bit unsympathetic if thats the case. --- " I was taken out into a pleasant exercise yard and offered a cigarette.

Handling loss of baseband correctly

site_archiver(a)lists.apple.com Delivered-To: bluetooth-dev(a)lists.apple.com Hi. Thanks, Nigel Spon _______________________________________________ Do not post admin requests to the list. They will be ignored. Bluetooth-dev mailing list (Bluetooth-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/bluetooth-dev/site_archiver%40lists.… I'm trying to correctly handle what happens when my device, which has an RFCOMM channel open, goes out of range. All my Bluetooth I/O is being done in a seperate thread with a CFRunLoop, and I duly get a kIOBluetoothRFCOMMChannelEventTypeClosed event. I release the channel with IOBluetoothObjectRelease, and on later callbacks triggered from my main thread, I try calling IOBluetoothDeviceOpenConnection, on the grounds that the baseband connection has gone away. If the device is still out of range, the IOReturn from this is 4, which doesn't correspond to any error code I can find. When the device comes back into range, IOBluetoothDeviceOpenConnection does return 0, which is fine, but then things go pear-shaped when I try calling IOBluetoothDeviceOpenRFCOMMChannelSync to get my channel back. The BT stack hangs inside that call and I have to restart the machine to kill it. This is under 10.4.10 on a 2GHz aluminium iMac. Does anyone know what I have missed doing here? --- "Quick!

site_archiver(a)lists.apple.com Delivered-To: bluetooth-dev(a)lists.apple.com Hi, I am trying to make make my computer act as headset for a mobile phone. Thanks in advance Thomas Sørensen _______________________________________________ Do not post admin requests to the list. They will be ignored. Bluetooth-dev mailing list (Bluetooth-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/bluetooth-dev/site_archiver%40lists.… I can get another make to recognize it as a headset and if I change the major service class to include audio my phone will also recognize it. Currently i have made the change through bluetooth explore, but i wan't the solution to be independent of this. The user should not use bluetooth explore to make this change. Do anyone know of a method to change the major service class through code or through the SPD ? This email sent to site_archiver(a)lists.apple.com
