Hi, can someone help ? I've tried a bluetooth headset Jabra 250 and also a Sony HBH-35 with a I-mate.
I can get them to bond and also identify as default headset but I can't transfer a incoming or outgoing call to the headset.
I've also done several soft resets and no improvement.
Any ideas ? do I need a new upgrade or something.
Other than this small problem, I'm very happy. I have also success with the Sandisk wifi SD card.
Thanks for any tips, Dave
how are you bonding the headsets?
on my hbh-60 I have to hold the button in for a few seconds
on first powerup to get it into discoverable mode(red/green LED flash)
Then search for it with the XDA/MDA/iMate
I have had no issues with bonding.
What version iMate are you running?

Hi,
I'm not sure what information about versions is needed to help resolve this problem but:
ROM version 1.03.00 USA
ROM date 09/24/03
Radio version 1.05.12
Protocol version 1337.12
ExtROM version 1.03.20
When these are not up-to-date where do I get the current ones from ?
Thanks, Dave
Have you turn on the bluetooth headset mode (one item on the default today screen, not the bottom right icon)
I have been using the Jabra bt200 for a while now. The problem is, everytime you turn bt200 off, you have to rebond again. It also works a bit differently. Once bonded, it automatically transfers to headset on dialout. For received calls, you still have to use the headset button. I am looking for another headset that won't require constant rebonding.
Hi, thanks again for the tips.
NOW the HBH headset works. I put the "profile" option back in the Today display and then checked everything again.
Then I tapped on the headset profile on the today screen - this turned it off. Then, I tapped again to turn it on.
Now the headset works fine !
I'll try again later with the Jabra.
Thanks - Dave
Thanks Much !!!
Just wanted to thank this forum and this thread. I just got a HBH-65 yesterday and could get it to bond ok, but it still wouldn't work. It turned out to be not having the "Profile" shown on my Today screen. I placed it back on the Today screen and enabled it and it works great now.
THANKS MUCH GUYS !!!

Ok, I have a BT200 that is working very quirkly with my i-mate. Sometimes the phone transfers the call to the headset, sometimes it doesn't. After deleting and recreating the bond, it works, but not for long. Anyone have one of these setup and working properly? Is there a trick to it?
Also, does anyone know if other headset drivers exist that may work on the i-mate that would allow you to hear all audio (not just phone) through a bluetooth earpiece?
Figured it out?
Ok, I've finally pinpointed that it works fine until I turn off the jabra headset, then when I turn it back on, I have to go through the entire thing again of re-creating the bond, etc..
Anyone know how to avoid having to recreate this everytime I turn the headset on or off?
I don't now ... but i have also jaba 200 and the MDA II is must arrive...
well please chip us informed
Thanks
DenisJ
I have the same combination and have also observed the same hassles.
It seems to work when I turn the BT headset function on the MDA off and on also. Thsi seems to result in a rebond.
Exact Steps
TBD,
If you could post the exact order of the steps you take to turn on / off the headset, I'd appreciate it. Right now, I'm doing the following:
1. Finish BT Headset Call.
2. Disable Bluetooth Headset Mode on Phone.
3. Disable Bluetooth on the phone.
4. Hold button on JABRA to turn it off.
Then, attempting to...
1. Hold button on JABRA to turn it on.
2. Enable Bluetooth on the phone (Set to "On" or "Discoverable")
3. Enable Bluetooth Headset Mode on phone.
4. Attempt to make call.
So if you could posts steps like that, i'd appreciate it. Also, do you set your bluetooth to "On" or "Discoverable"? Do you ever turn off the Bluetooth Radio completely?
Thanks,
Jon.
Yup me an all. I too have the Jabra BT200 and have the same problem. Providing you don't switch off the headset or go out of range your ok, but for instance when you leave the headset in the car and take the XDA2 with you you have to create a new bond to use it again. AHHHHHHHHH!!!
Shame cos so much else has been sorted on it.....and more. What a piece of kit!!
SOMEBODY HELP!!!
OK, so here is the sequence, which seems to work (for me).
1) I set everything up as per instruction. creating the bond between the Jabra and the MDA II.
2) Before (or after) I turn off the Jabra I disable the BT-Headset on the Today-screen.
3) Then I turn the Jabra on again and wait several seconds before enabling the BT Headset on the MDA II.
This seems to work most of the time, though the hint regarding going out of distance might explain the instabilities I have still observed. In any case, using the BT-Headset ON/Off on the Today-screen seems to resync things most of the time and get the Jabra up and running again.
Hope this helps and always open for new ideas
I have been a bit impatient after turning the BT headset on. I'll try it and let you guys know.
I may have been a bit optomistic. :roll:
Today I observed that sometimes the Headset reacts very late. Consequently you miss half of the call. Seems to be an XDA problem.
As for my XDA II with Sony Ericsson HBH-65, after creating the bond, before i turn off the BT headset, i turn off BT profile and BT on my PDA, then turn off the Headset.
If i want to turn on the headset, i activate BT on my PDA, then BT profile, the the headset. Sometimes in teh day headset seem to lose the bond and cannot use the BT to call or whatever. I tried turning on/off BT on my PDA, did not work. Turn on/off headset, it worked. So for me most of the time is my headset causing the problems
i am having the same problem with the new moto bluetooth headset although i have experienced no problemzs with the se hbh-30 bluetooth headset....i can turn off and transfer calls without any impact on teh bonding
Jabra problems
I've had similar problems on a boring old Nokia 6310 with my BT200. In the end, all I could do was find the 'automaticly reconnect' option on the Nokia. during calls, the link is allways fine, but between calls, when I guess one end or the other goes to sleep, the link will drop out, and then instantly reconnect. This happens around 2 or 3 times an hour.
Is there a 'automaticly reconnect' option on your XDA?
All the best
James
OK, I finally sacked my Jabra 200, because of its instability. What use is a headset, that doesn't repond when a call comes in? :evil:
I bought a B-Speech from B-Data yesterday and it seems to be working much better :lol: .
Nokia HS-3w headset with XDA II
Well! I am using the Nokia HS-3W Bluetooth Headset with my XDA II . I can pair up two devices and use it for only ten minutes :twisted: . After that, the headset will off(goes to sleep) . I Have to turn on the headset every ten minutes. I ask the dealer about the problem. They told me this headset work fine with Nokia's phone. They told me , there is three color on the light. Red light will flash when you turn off the headset. Green Light will flash when you turn on the headset up to ten minutes, if cann't find the phone devices , it will goes off.White light will flash, when the headset connected to the phone. When I turn on the headset, I just can see the green light only.But, if someone call me or I make a call ,the white light will flash.After the that the headset will flash the green light again for about ten minutes and goes off. Can anyone help me with this problem? Thanks!

Hi, I will like to ask how your headset B-Speech is working.
It works 100%?
I have a jabra 250 with the same problems as BT200
Please let me know
Regards
JoseF
The B-Speech Headset is working OK, however it doesn't solve the problems with the Microsoft BT-stack.
Some observations, probably also applicable to the Jabra:
:?: When you go out of range with the headset, it will probably not reconnect automatically (but how do you know)
:x On an incoming call, the XDA may be very slow in activating the headset, so you might miss the call (seems to be tied into what the XDA s/w is just doing at the time
When you turn the Headset off, make sure to turn it off on the Today screen first. And when you turn them on, make sure to wait about 2 sec. after you turn the headset on before turning it on on the Today screen.
:idea: What seems to work best, is turning that Headset off and then on again on the Today screen. It usually comes back after that.
Mind you, it isn't the headset thats causing these problems. Its just that Microsoft botched the Bluetooth stack - probably the programmers had blue teeth from all the wine they were drinking!
I've found the out of range issue to be mute on my jabra 200. The only time the bond is broken is when the headset has been turned off. Or sometimes when it has been on charge.....
Strange........I use the Jabra BT 250 with the MDA II and have non of these reconnection problems. I f I turn it on and place a call (or receive) it reacts immediately.
However, I cannot use the advanced Headset Profile features of the Jabra with the MDA, but this is not the fault of the Jabra........
Could the people who are having problems and the people who are not having problems with their Jabra BT200's please post their version numbers of the Jabra BT200. You can find the version number on the boom going to the microphone. It will be 2 numbers and a letter, like 48A or something like that. I'm testing a theory that I think will help identify why some people work and some don't.
Thanks,
LouisK
Ok, the number on my Jabra Bt 250 is 44B.
I have been using a JABRA BT200 Headset with my XDAII and have always had the same problem, once the BT200 has been paired with the XDAII it works fine but once I put the headset into it's charging cradle and then remove it and try to use it again it always loses it's bond, the only way I can get it to communicate with the XDAII again is to pair it again.
I don't know whether the problem lies with the BT200 or the XDAII
Does anyone else have this problem ???
Thanks
Ian Goulding
hey ian,
it was just recently that i was able to figure out the bt-xda2 bonding; thanks to some helpful chaps in the forum. in the process; i did some research within several topics and read something which may answer your query. when the headset is back in it's cradle; i believe it's "turned off" or is put into inactive mode. the forum message i read indicated that the bonding is lost once the headset is turned off; thus you have to bond again. yes, i have had similar experiences while figuring out the bonding issue. i just keep the bt200 i have out of the cradle; when the time comes to charge it i then holster it and repeat the bonding process once it's charged. i don't think it's a problem with neither devices; it's the default setting i believe. with luck probably the xda-developer guys will come up with a bug fix for this item. which could also include using bt for other than the phone function...like mp3....hint! hint!
cheers

I've installed Towa's GPS BT patch and the Jabra works perfect.
hey redbull,
what's the Towa's GPS BT patch and where can i find a link?
cheers mate
robson
Towa's gps patch has nothing to do with this...
I'm not sure what you are talking about, but Towa's patch will not solve the Jabra BT200 issue. The more important question to look at here is what version of BT200 you have. If you look on your Jabra BT200 right next to the microphone, there is a combination of letters and numbers, what does yours say? I think the problem has to do with issues in the firmware in the Jabra that were fixed in later versions.
It's usually 2 numbers and a letter on the boom to the Microphone.
I have a 47A and it does not work at all. Also tested a 48A and it doesn't work either.
mine's a 48b. works fine.
Cool, just so we are talking about the same thing, you can turn off the Jabra BT200, and turn it back on, and it still works with the phone? You can charge the headset in it's charger and pull it out and it still works? You can go out of range and then back in range and it still works? You can press the answer phone button on the headset when no call is in progress and then try to make a call and things still work?
Please try these various things and let me know.
I know that the A models are from 2002, and the B models are 2003. So it is possible if yours works with all these scenarios that they fixes or changed something in the 2003 models that allow them to work.
Thanks for your time,
LouisK
I recently purchased a BT 250 with nr. 44B and indeed it works with all the tests you described. (Don't need the BT GPS patch for that)
If only the advanced Headset Profile features would work with the MDA II I would be in heaven...........
Ok, it seems based on feedback I've gotten from several people that any Jabra Freespeak that has a "B" as the last part of it's version number will work correctly, but the "A" models do not. The "B" models according to Jabra are the most recent, and thought they don't admit it, there must have been a change in the firmware that allows the "B" units to work correctly with an XDA2/MDA2/i-Mate that the "A" units don't support.
LouisK
I have a "B" on mine and the same problem of rebonding when Jabra is shut off. I experimented by turning off bluetooth on the i-mate and it still worked. Anyone have ideas of a good headset that will not need rebonding?
I have problems with mine too and its a 16B. Turn the BT headset off and its rebond time again.....
48B works fine for me... can't everyone else just use TOWA's patch... that fixed the problem for others

16B is no good. I've been told that minumum needed is 19B. Below 19B is bluetooth 'handsfree' not 'headset'.
Towa's patch has nothing to do with this. It will not help in this situation. It only applies to Bluetooth Serial Profile, of which the Jabra has none. I have talked to Towa via email to confirm this. For those that installed Towa's patch and said it works, more than likely they didn't have the problem anyway because of the version of Jabra they had.
BT jabra 200/plantronic M3000
Jabra is model 45B, - no nead to repair, Plantronics M3000, no need to repair, but sometimes fails to answer call properly.
Hi 2U all,
I have just purchased a BT200 off Ebay, the number on the boom is 20B. No problems works well , no rebonding problems. Just one wish, it would work with voice. But I will keep praying!

EMAIL FROM JABRA RE-Bonding Problems with XDA-II
:roll: :roll:
Dear Ian,
Thank you for your e-mail and please accept our apologies for the delay in reply.
We are sorry to hear you are experiencing problems using your JABRA BT200 headset in conjunction with your O2 XDA II.
However, having tested the JABRA BT200 headset with the XDA II, we have encountered the following problems.
When completed charging the headset you will need to synchronise the Headset and the Audio Gateway in your XDA II.
Please follow the steps below:
Select Bluetooth menu> Select Off> Select OK (BT is now disconnected)
Return to desktop (Today view)> Disable BT HS mode> Enable BT HS mode (User
to be prompted to turn On BT radio)>Select OK
Enter BT menu> Select On> Select OK (The XDA II returns to the "Today" view
and will try to synchronise with the HS again.
Check connection by establishing an outgoing call. If no sync - you will need
to re-pair the two devices)
We hope this will solve your problem for you. If you require any further assistance please do not hesitate to contact us again.
Thank you for contacting JABRA Customer Service, Europe

Seems to me that without actually saying it, JABRA think that the fault lies with the XDA-II!

15B, can it be upgraded?
Hello everyone...
I have an MDAII and a Plantronics M3000 BT headset and I have the same pairing problem.
I always have to repair the two divices for them to work...
Any ideas?
Best regards,
Rayan
I decided to open a new thread although there were several threads on the use of bluetooth headsets. My intent is to explore whether there is a particular sequence that we need to follow when operating the XDAII and BT headset. I am using a Ericsson HBH-65.
First observation:
I notice that I need to end all calls via the bluetooth headset rather than from the XDAII. If I end a call using the XDAII (ie depressing the red button), for subsequent calls whether incoming or outcoming, I cannot use the headset. There is no connection between the 2. I seem to be able to simulate this almost 99% of the time.
Second observation:
I normally switch off my BT headset overnight for charging purposes etc. At the same time I deactivate the BT settings on my XDAII.
The next morning, I would activate the BT settings, BT profiles and then switch on my headset.
I notice that for the first call I made/receive the next day, I will have problems using the headset. I am not quite sure whether it is the case that I need to switch on my BT headset first and then the XDAII BT settings and BT profiles. I say this as to resolve the problem, I seemingly need to deactivate/activate the BT profile settings before it works and then for subsequent calls I would have no problems using the headset. This needs further testing to test my hypothesis.
Anyone notice anything different on their part.
regards
Same issues
I have had the HBH-65 and have noticed the same issues. I have also had an Logitech and did not have any problems with that.. I am guessing the issue is with the firmware on the HBH-65.
I use Bluetake GII with my xda2. No sequence, no problems. I never even think about switching it on or off. Works in any sequence. Nice looking too! :wink:
I have a Jabra 250, and I do not have to follow any ritual to have it to work fine
I have a Logitech Bluetooth headset with my Qtek 2020 (rom 1.60.21), and it works like crap.
First of all, the headset wont turn on/off sometimes.
Second - if its turned on, and the qtek has been turned off, i need to reconnect it, to switch automatticly when recieving a call.
Thirdly - both speak and hear is very poor quality/fare away (very silent) even though ive turned the volume to maxx.
BT Headset - Works Flawlessly
I have a Sony Ericsson HBH-30 headset and I never give the slightest thought to sequences or procedures. I can turn the headset on and off, the profile on and off, even the BT stack on and off - without ever having to re-bond or anything else.
Now if I could just voice-dial a call with the bloody thing I would be truly happy indeed.
Same problems but getting it figured out
I have the HBH-65 and it seems to work fine now that I've hopefully figured it out. I do a few things. First, I leave the Bluetooth on, on my i-Mate. Second, once it's in range I've noticed it takes about a minute for it to link up. When it links it either makes a single beep (if I just turned on the Headset) or a quiet click if it was already on. I doesn't work ALL of the time, but the more I use it the better it gets. I really expected it to be a little easier.
I have the HBH-200 with call display...which the salesman assured me that it would work with my XDA 2! Call display does not work, and if I end a call on the O2 the headset will hang. Other than that it's great!
I Have a XDAII and a HBH-35
They key to it seems to be not to turn anything off ! it's really frustrating when you think it's all linked up and then get in the car only to recieve a call and not be able to answer it with the headset.
If I have turned the headset off it's a right pain to bond again, red, green lights, funny beeps it's very confusing !
Once it's bonded it's great ! I am amazed with the call quality.
I have an Sony Ericsson HBH 35, I have no problem w3ith the bluetooth pick up call are end calls.
I can even transfer call from my bluetooth to the handaset and by reverse pick up call on my handset and then transfer the call back to the headset all I have to do his to hold the button on the headset fro a few second and the call transfer from the handaset to the bluetooth headset no problem.
Great piece of headset I would really reccomended it to anyone.
The rom on my XDA II is still the version 1.05
Regards
Gigino
Cheers Gigino
Do you ever turn your headset off or disable bluetooth?
I don't have any problems when it's bonded. Just problems if I turn the headset off to save battery
I only turn the headset off at night when I charge it. I use to swwitch off the headset but not anymore becauswe if it is on it use very very little power so it last all day with no problem.
The bluetooth on the XDA II I have never turn it off since I bought it 5 month ago the bluetooth headset on the XdA II is always on.
I've try it switch it of and then on the bletooth and the bluetooh heaset on the XDA II but when I turn it on and turn the headset on it all works fine.
They is no issue on the headset I've tryed every diffrent combinetion the is and the headset works fine.
I have never needed to rebond the headset with the XDA II.
The only thing I have not try is if I can receive a second caller.
Mean trying to switch between 2 caller when I have the chance I will try it.

Gigino

I have bought a Plantronics M3000 bluetooth headset for my QTEK 2020. I have no problems pairing, calling and answering. However the headset just shuts off after a few minutes of conversation. It doesn't just cut the conversation but shuts off. I can make multiple short calls but nothing longer than 3/4 minutes. It works, however, without problems on my wife's Ericsson T68. Anyone can help ? Thanks.
Marek
Hello,
I have the MDA2 (same as QTek2020) and a Plantronics M3000 and It's been working just fine.
The problem you describe it's very weird since you mentioned that the headset works fine with your wife's mobile, and that makes me think that your QTek has some sort of problem with the Bluetooth stack or hardware.
It may be well worth to try (if possible) another headset just to make sure that is not the M3000 fault.
Do you see any type of error or message on the screen at the time of disconnection?
Does it always cut the conversation at the exact same moment?
Does the problem match the time the QTek takes to power save?
Any other clues?
Thanks.
I did not have the occasion to test another BT headset on the Qtek. When it shuts down there isn't any message displayed.
I have no problems with the BT stack (with the Pocket Bluetooth Tools patch) when using it with a BT GPS (Emtac) receiver, it works for hours.
However, your suggestion that it might happen when the Qtek goes in energy saving mode is interesting. I will check that tomorrow.
I'll post the result.
Hi
I seem to have a similar poblem after installing pocket bluetooth tools!.
I use a Jabra BT 250..and I noticed that the headset just mutes during the call..
I am generally used to switching off the display of the XDA after placing the call to power save ...
So I discovered that the headset would mute whenever i switch off the xda after making the call (which it never did prior to installing PBT)!
any thoughts on that?
maybe it has to do with the auto switch off plugin?
Actually I just experienced that too...
If I place (or answer a call) the next time I try to use the phone via the BT headset I notice the BT headset was turned off... Yeah, it could be related to the Powersave feature on the today plugin that PBT installs as a plugin... :roll:
Need to investigate...
Best regards,
Rayan
Both my bt headsets have stopped working since installing pocket bluetooth tools latest version, I have reverted back to version 1005 and everything is fine. I have a sony-ericsson EBH-65 and a skypower clip on headset.
my platronics does the same also its annoying you cant even transfer the call back to the device you have to hand up turn off bt and then turn it abck on and headset mode back on it also does the same on my pc
when im on msn using it as a headset it just d/c and i have to turn it off and turn it back on again
dont see what the problem is
btw the range on the xda2 and platronics is amazing i had it on my bedrooms desk and i went outside it passed through the living room wall and the patio window and i was stood 5m down my garden im sure it would of been over 10m and it was still working if i kept still when i moved it went crackly but ah well lol
just hope someone sorts the prob out
Hi,
I was having the same problem with the M3000. I just had confirmation from Plantronics that this problem is a bug in the product that occurs with the XDA II. I am currently in the process of returning the product.
Regards...Mike
Same problem M3000 doesn't work. Give up now before too much frustration makes you feel ill.
Try the Hello 2 headset. Work with my Aussie XDA2 and is very small and lightweight. Even had a neck chain to carry it around like a USB drive.
Help!
I have had my M3000 for about 8 months now and until recently it has worked fine.
Last week when I answered a call with it, the headset turned itself off after about 2 mins of talk time. The phone thought the headset was still connected and I had to transfer the call back to the phone, and end the call before I could do anything else. It is now doing this regularly.
I have re-bonded and the headset is fully charged (even tried it while connected to charger!)
I have also tried to run the headset against my pc (audio output) and this works fine.
The only thing I can think of is the battery in the 3000 losing its charge when connected to a phone, but when I charge it, it is ready in a matter of mins.
Anyone any other suggestions as to why the Headset powers itself off ?? Has anyone seen this behaviour before ??
Thanks in advance.
mine does the same mate its the platronics m3000 its crap and doesnt work well with the XDA2 use the bluetrek G2 they work great
Mine did the same, but I just noticed that the XDA2 was on Bluetooth Discoverable mode, when I switched to Bluetooth Connectable (On) it works fine
Thanks to all who have replied....
I have tried a few more things out :lol:
1) Logged an issue with Plantronics :wink:
2) Tried my BT Carkit which works no problem :lol:
3) Tried a Hard Reset - Works great afterwards :lol: until I install my apps
It has therefore got to be a problem with apps and rom version clash??
Those who have had similar issues with the Plantronics turning itself off after using it for more than about 1.5 Mins.... Do you have any of the following apps ???
Belkin IR Keyboard Drivers (Belkin WPDAK)
Fonix Voice Dial/ UK Roger

Plantronics Bluetooth Headset
I also have the same problem. I also have a SanDisk wifi card (which on occasion also stops working causing me to hard reset) and Microsoft Voice Dialler and Pocket Breeze and a number of other plugins. The whole point of plug-ins is to use them! Any suggestions???
David
It gets worse!!
I have just tried the Widcomm stack on the XDAII.
Its probably me, but I just cant get the thing to pick up the headset when I make or recieve a call, so that was no use.
To uninstall Widcomm I had to do a hrad reset (Widcomm disables the sound after uninstallation for some reason - grrrr), and now the damm thing shows the same symptoms - even on a virgin hard reset device.
My only conclusion is that something changed in the last ROM to kill it. I'll wait for another ROM upgrade and see what happens then, but will now probably end up buying another headset.
Is anyone on 1.72 with a Plantronics that works??? :?:
Ian - Rom 1.72
Do you have the 1.72 Rom on the XDAII from the UK? I thought it wasn't out yet. Is it better than 1.60?

Yep 1.72 UK.
Its better than 1.6x but has still got issues with it - like needing to be hard reset every now and again (grrr). But BT is more stable and power drain is better.
