I found this a week ago. :D

And to tell you more, mine does have a common profile.

[sweetpete]

Eitel, have you tried recording sound through the mic?

[kagayaki1]

Anyone tried this on a 3870?

Not yet. I'll try this tonight.

I have used the mic on the Bluetooth headset with the voice recorder on the h5450. Works very well. Obviously, the sound quality of the headset is not up to par for MP3's, but it's fine for Audible books.

I'm hoping this will work with, say, an H3955 with a Socket Bluetooth CF card, right?

I'm afraid not :cry: - at least not at this time. The headset profile uses a different method than any of the non-audio Bluetooth profiles.
The 5450 uses a newer version of Widomm's firmware than previous iPAQs, and I don't know if it would be supported by the hardware in the other models.

[MooseMaster]

Well I've got one of those bluetooth "headsets" that goes through the car stereo so I can talk on my cellphone through the car's speakers and I've been asking around on about every forum I could find if this could be done. Now I see it can and its for the H5400. ... can I trade my H3955 in for credit on the H5400? ;-)

I have a 3630 with a Billionton CF BT Card which is based on widcomm BTStack, guess what?

I have goto the registry, look at the service, there is no Dword about Enabled... I thought its going to be no luck, but I add that key in... reboot... MAN THATS AMAZING.... I HAVE THAT WIZARD COME UP!

Now I dont have a BT Headset with me, else I should be able to test things out!

I've been wrong about such things before but...

I doubt that it will work. Most likely the wizard was hidden because the hardware doesn't support it.

[William Yeung]

I have borrowed the BT Handset of ericsson, I will test it out tonight.

Em... at least the spec of my CF card stated that it supports HSP on hardware, so my guess is it might be the case similar to what is happened on H5450...

[bucho]

That's cool... I paired my Jabra with the 5455 last week, but I saw no services, so I gave up. I did it again after reading this thread and it sure works! Incidentally, I was playing with "voice recognition" software the other day, so I figured... let's give it a try and see if it's usable with the Jabra over BT. So I loaded VoiceControl from fonix.com, connected the headset and was able to open my Inbox, read 11 new messages, delete etc. while the 5455 was in my pocket the whole time!!!

Man, this just left me hungry... Now I wish VoiceControl had more functionality. I don't know if anybody used this type of software, but the recognition accuracy is astonishing and it requires no training at all. Compared to the T68i voice commands, it's light years ahead. Paired with a BT headset like Jabra... damn! I wish I can control everything on the PDA through voice. It looks like the IBM software may be better, but it won't install on the 5455.

Anyway, anybody tried a BT headset with VoIP software on 5455 yet? I'll give that a whirl tomorrow and report... BTW, the quality is not worse then I use it with the T68i and that means pretty solid since people can't even recognize that I'm using a headset when talking.

I guess no, not yet - but I'm still waiting, as mine gets used for a GPS unit, and would be ideal if the sound could be piped through a handsfree kit.

Does this mean that mobile phone software could be run in a non-passive state if the headset could be handled by an iPaq and sent back to the phone?

[Philip Colmer]

One drawback that doesn't seem to have been picked up on is that most (if not all) BT headsets only pair with one device at a time.

So, if you use a BT headset with your mobile phone and you also want to use it with your iPAQ, or your PC with a BT card, you've got to re-pair it.

And then re-pair it again with your mobile when you want to use that.

A bit of a pain, but I think the limitation stems from the fact that you haven't got an easy way to manage paired devices on a headset, so the only user interface they can readily support is to overwrite the existing pairing.

Sorry - that's what I meant. If the headset was paired only to the iPaq, and the iPaq did the sending and receving of audio back to the mobile.

Jabra Freespeak for BT devices *does not* support 2 profiles. I emailed Jabra tech support couple of weeks ago asking for more information about it and got no response.

[William Yeung]

I have tried the headset trick with my bluetooth CF + 3630 + Ericsson HBH-10, no luck, things paired up, but no audio redirection... I think its the underlying driver need to be adjusted

[MooseMaster]

Does SocketCom or other manufacturers have the ability to add profiles through driver upgrades or are profiles built into the device and not upgradeable?

Well I have the new Motorola headset that support mulitple partnerships. While I can partner with both my phone and my 5450, the "handoff" is not automatic. So this saves you from doing the pairing each time, but it's still impractical to use since you would want the headset to give an incoming call on the phone priority and swtich devices. It can't do that. :?

Of course if you run a Bluetooth news site and therefore happen to have more than one headset... :wink:

How do you get to the registry?

How do you get to the registry?
There are a few registry editors (you can find them via the www.PocketPCMag.com web site's software catalog. If you are unsure about what you are doing I would recommend a program that controls what changes you can make. As I recall, "Tweaks2K2" has been updated to support enabling the Bluetooth headset profile in the h5450.

[Mark R Penn]

This works well on my 5450, but as far as I can see, if I then want to use the headset (Jabra BT200) with the phone, I've got to pair it again? Is there any shortcut way to do this, i.e. switch the headset from PPC to phone and back?

Cheers,

Mark

As I indicated in my previous posting here - it depends on the headset model you own. If the Jabra only supports pairing to a single device (as is the case with most headsets) then there's no shortcut.

Some newer headset models support multiple paired devices. However, at this time none seem to allow for "smart" hand-off when in use. That is, if you are listening to audio from your Pocket PC and a call comes in on the phone, the headset should "dump" the Pocket PC connection and take the call. However, they don't. With the Motorola, you need to manually end the audio connection and then have the phone request a new connection. Obviously this is not practical when trying to answer a call before it falls over to voicemail. For this reason, I don't currently use the headset feature of the Pocket PC. (Besides, the audio quality is only useful for voice and not music.)

I will have a review of the Motorola headset posted on www.BluetooothNews.com some time next week. In that review I will discuss this issue in greater detail.
