Well, that may not be the optimal user experience, but I guess you already know that. :-) I'd rather see that it in the "Other Device" displays all and every device it can find but tells the user with a dialog or something if something is less than optimal for pairing. It fooled me, and I have read both usb and BT specs, and done some programming for both too and built my own USB BT dongle when those were rare and expensive (you may remeber I reported a bug or two in the beginning, but it still works fine!). :-) Anyway, I have now got the "Headset" radio button too and have happily paired with my ancient HBH-10 and have sound go both ways. :-) --On den 6 februari 2004 15:56 -0800 Eric Brown <esb(a)apple.com> wrote: Additionally, the HBH-10 headset isn't officially supported (nor is the HBH-15).

Sure, no problem, and I'll get a modern one now that I have a reason! It works quite good, though! I had a problem once with it saying something on the lines with "Only use one bluetooth headset for audio at a time" or something like that whenever something was trying to do some audio, I couldn't make it stop with less than a reboot. I have also seen it not beeing able to connect if I don't push the button on the headset first, or at least that is what I think happens. :-) But never mind this old stuff.

Sources for Bluetooth modules?
by Chilton Webb 07 Feb '04

07 Feb '04

Hi, I'm trying to find a source for bluetooth headset modules. Ideally, I'd like to find a single board/module that encapsulates everything I'd need to build a headset, sans amps, preamps, power supply, etc. I'm looking for Bluetooth Class 2 devices at this time. I've found three sources of parts that get me pretty close, but this seems like something there'd already be a solid source of. National Semi has a nice array of components that get me pretty close. Any favorites?

Hi Ragnar, The BSA will not display SCO devices in any list if you do not have a dongle that supports SCO. This was deliberate, since you can't use the SCO device without the proper hardware, and we didn't want users thinking they could. The pairing panel lets you pair with anything, but as you have noticed, it does not set up the device fully for proper use with the system. It is more of a 'power-user' backdoor to simply pair with any device.

BT 1.5 SCO-audio and Eri HBH-10
by Ragnar Sundblad 06 Feb '04

06 Feb '04

Hello all, Sorry for this kind of user oriented question, but: Has anyone got the Bluetooth Setup Assistant to work with the very old (the first?) BT headset Ericsson HBH-10? The assistans intermitantly says "Updating 1 name(s)", but then it goes back to "Searching for devices - 0 found."). Pairing through the control panel works fine, it gets it's name and all, but then I don't get any audio channel set up. It also works in 10.2.8 with assistant and stack 1.3.3. So there seems to be a difference in how the 1.5 Bluetooth Setup Assistant and the control panel reads names or some other information from devices, and the former fails, but I can't say that there is a bug, the headset may very will be doing something wrong (I think it was made far before BT 1.0b). Maybe I should add that I don't have a SCO supported dongle, but I beleive that pairing should work anyway, with or without audio. I have tried with two different USB dongles. Getting a SCO supported dongle (or at least what seems to be a supported dongle ;-) is another story. This is no big deal, I can buy a modern headset and/or a supported dongle, I just wanted to play a little. /ragge _______________________________________________ bluetooth-dev mailing list | bluetooth-dev(a)lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/bluetooth-dev Do not post admin requests to the list.

The headset will always show up in the sound prefs until the pairing is deleted. Turning off the phone or disconnecting the baseband link is not the same as unplugging a set of speakers. Deleting the pairing is a closer match. When the headset is in use and is powered off, there is a hardware timeout that must occur before we are informed that the link has been lost. At that point, the error panel described above is presented. In the above scenario, it sounds like the link wasn't up when the device was powered. It is likely caused by the fact that the sound prefs attempts to open the current audio device when it is displayed (for the input VU meter). The audio device open / start process is synchronous and must wait for an attempt to connect to the headset to fail (~5 seconds). The fact that the process is synchronous and can't be cancelled is what causes the spinning cursor. As soon as the connection failure occurs, control returns to the sound panel and further user input is processed. - Eric [demime 0.98b removed an attachment of type application/pkcs7-signature which had a name of smime.p7s] _______________________________________________ bluetooth-dev mailing list | bluetooth-dev(a)lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/bluetooth-dev Do not post admin requests to the list.
