This sounded promising, but unfortunately replacing -closeConnection with -destroyConnection doesn't seem to make any difference. That is, the device can still enter a state where a connection can neither be made nor closed (and PacketLogger still reports "ACL connection already exists" upon attempting to open a connection while in this state.) Thanks for the suggestion though. David _______________________________________________ Do not post admin requests to the list. They will be ignored.

Repeated attempts to open a connection results in the same behavior, and calling -closeConnection returns 0xE00002C0 ("no such device", according to IOReturn.h.) Once in this state, opening a connection to the device becomes impossible, and other Bluetooth operations fail for the device. I'm looking for an API to get the Bluetooth stack out of this inconsistent state. So far, disabling/reenabling Bluetooth fixes it, as does the "Modify Software Configuration" dialog in the Bluetooth Explorer app (I'm still investigating which specific option fixes it.) There are a few other interesting details: o -connectionComplete:status: claims success, but PacketLogger says the actual status after attempting to open the connection is "0x0B - ACL connection already exists." o Calling -closeConnection does not generate an HCI command; I'm hypothesizing that the problem would be fixed if the APIs would actually issue the HCI command. o Here is the PacketLogger log for the repeated connection attempts (which contains information about my host system, Bluetooth chipset, etc.): http://themha.com/OpenConnectionLog.zip. Perhaps someone knows of a programatic way of getting the Bluetooth stack out of this corrupted state? Thanks!

site_archiver(a)lists.apple.com Delivered-To: bluetooth-dev(a)lists.apple.com A radar is always the better way to make sure bugs don't get lost. Please file one for the Boolean parsing being wrong, and the crash in blued. As for putting binary data into a string SDP element, this is kind of overloaded to make SDP records look like plists. In order to force the data to not be parsed by CF/NSString, use a dictionary of the form Item (dictionary) DataElementType (number) : 4 (SDP string type) DataElementSize (number) : length of data DataElementValue (data): raw data IOBluetoothAddServiceDict is currently the only way to register a service, but we are looking to deprecate the older C API, which means making Objective-C alternatives available wherever needed.

site_archiver(a)lists.apple.com Delivered-To: bluetooth-dev(a)lists.apple.com Hi I did more tests with dictionaries and found out that IOBluetoothAddServiceDict fails to handle BOOL data elements. If I specify an attribute like this: Item (dictionary) DataElementType (integer): 5 DataElementSize (integer) : 1 DataElementValue (integer): 1 the service record received by a remote device lacks the value byte, and gets the header of the next data element as the value of the BOOL entry. It did not crash for me but this clearly is a bug. Can someone from the Apple devs please have a look at this? (I guess posting here is more efficient than filling out a rdar - google could find this mail). Also, does anybody know if are there other methods/functions, maybe private ones, that add a service that contains BOOL attribute value?

site_archiver(a)lists.apple.com Delivered-To: Bluetooth-dev(a)lists.apple.com Hi Thomas What service/application do you want to build? I've also recently ventured into the less documented area of providing SDP services, more specifically a HID keyboard. With quite some guessing and trial and error, I got another Mac to connect to my HID service, but so far failed to send a key event in such a way that it would cause an action on the remote Mac. Anyway, setting up the Here is the code to register the service: http://pastie.org/1049131 And yes, there is a ObjC alternative to the C functions, see code. How can I see the bug report you mentioned (rdar:5094971) - I logged into bug reporter but could only see/search my bugs. Could you send me a summary please.

That failed, due to bugs in OS X (rdar:5094971). Later, when I had long given up on this project, I received note that this issue had been resolved in 10.5. I received no details on how this was resolved, though. Now I finally tried again, and this time, it's gotten worse: While on Tiger I simply noticed wrong SDP entries for my registered service, now the same code crashes blued, apparently. All I do is to invoke IOBluetoothAddServiceDict just as it's documented in Apple's BT docs under "Adding a Service Definition to the SDP Database". I've been trying with two different HID plists, one for a simple "3 button boot mouse" and one with what Apple's own original Bluetooth uses. Neither the crashlog nor the syslog are giving any helpful indication what's going wrong. I'm trying this on 10.6.4. Does anyone know more on this? Has anyone ever successfully registered a HID service on OS X? And is there perhaps a ObjC alternative to this C function? I could not find one. -- Thomas Tempelmann, http://www.tempel.org/ _______________________________________________ Do not post admin requests to the list. They will be ignored.
