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 currently writing an OS X driver for a new Bluetooth device. I do, however, have problems to get a baseband connection to the device through all of - [IOBluetoothDevice openConnection:withPageTime:authenticationRequired:] returns 4 via the delegate connectionComplete:status:, even when pageTimeout is (4 * kDefaultPageTimeout)) In PacketLogger, I can see page timeouts for Write_Authentication_Enable as well as Create_Connection. On the other hand - [IOBluetoothDevice getServices] returns the device information (but then I'm aware that that info may be from the cache of the BT stack from previous successful pairings => see below). After a few tries, I can pair the device successfully when going through the OS X Bluetooth Assistant, selecting "All" and "Empty password". I'd like to be able to directly pair with that device, though, using IOBluetoothInquiry and IOBluetoothDevice. I tried IOBluetoothPairingController as a middle way, but it doesn't seem to allow me to set that an "empty password" be sent instead of prompting the user. Instead, it will prompt the user for a password. Is there any API I've missed that allows me to pair directly with a device that requires authentication with an "empty password"? Also, what does "empty password" mean in technical terms? I couldn't find any info on this in the Bluetooth specs. Thanks for any insight and help you can provide. I can't wait to get support for that device into the hands of OS X users. This email sent to site_archiver(a)lists.apple.com
