Bluetooth Stack revisited

Now that we're likely to get a working solution for our Bluetooth worries thanks to TOWA it seems sensible to revisit the BT-stack implementation on the XDA II. I spent some time working through the Microsoft documentation to come up with this assessment.
All previous PDA's have used the Widcomm stack, which supports a multitude of BT-profiles,specifically the Serial Port Protocol, which it emulates as a COM-port. Unfortunately, the Widcomm stack does not support the Headset service, which is required for the phone. This is why the installation of the Widcomm stack on the XDA eventually failed -just couldn't support the headset.
The Microsoft stack actualy also supports the serial port profile, but uses a different implementation. Their BT-stack is socket based and aligned very close to the IRDA-implementation we all know from our PC's. Just as the PC generally requires that famous "IRCOM"-applet, so does the Microsoft BT-stack (this is basically what TOWA is working on).
The Microsoft Bluetooth stack is actually very flexible, which gives us hope of seeing the XDA II support more and more Bluetooth functions as time goes along.

But why did MS not implement the COM port? If it takes TOWA a week to do the job with limited resources, why couldn't MS have done the same? And if the MS Stack is flexible, why do they leave out functions when they release it?

I'm sure MS could have done it, but the they didn't do it for IRDA either.
I think they are trying to push their implementation architecture upon us.

I would like to take this oppertunity to thank Towa for the great job he did with the TOM TOM gps bt issue. I will be getting my imate(xda2...) ppc soon, and I have the following questions, as I am quite a novus:
1. does the gps doohicky that Towa wrote enable the xda2 to work with the bt headset as a handsfree profile, since the xda2 only supports headset profile? or is it only to create a port so the tom tom can find it and work with it?.
2. If no to question 1, then I would like to share my expieriance with bt headsets, which I cannot understand untill this day and may be you can help?. I currently use a Nokia 6310 and previously was using it with the Ericsson hbh-20. Since, the Nokia phone did not suport voice activation or reject a call from the headset, I could only voice dial through the headset after I pushed a button on the 6310. So I thought, no biggie it was Nokia's fault since I successfuly voice dailed when paired to my friends t 68. Then I tried my 6310 with my other friends hbh-30 bt carkit, and wouldn't you know that the voice activation from the bt carkit's button worked like a charm (stumped. who to blame know, we always need someone to blame.) So, after that my third friend bought me the new Nokia clip-on bt headset, it works as a complete handsfree headset with my old Nokia 6310, rejecting, auto answer, voice dialing ... all from the headset. So, my question is do I have too many freinds? (just kidding), how do you expect the xda2 and the new Nokia clip on headset to communicate with each other?. In headset profile or handsfree profile?.
3. If your answer to question 2, is headset profile, then will we have to beg the "Great One" also known as "The Man" (as qouted earlier on gps bt forum of this site" Mr.TOWA himself, to write us another doohiky to make them work in handsfree profile.
p.s. In my opinion, anyone who has downloaded Towa's doohiky for gps and had a positive result, should donnate something for this hard worker.
Thank you, and sorry for being so boring.[/quote]

TOWA's great app only fixes the serial port issue, by basically establishing a permanent virtual com-port using the functionality built into the Microsoft BT-stack.
Unfortunately, inmplementing a Handsfree profile will be much more complex, so don't expect a quick fix on that. I'm sure HTC and Microsoft are working on it, but I wouldn't expect a fix this year.
Regarding your BT-observations, it seems that the implementation of the profiles on each device is different and probably none of them are really complete.
I think the Bluetooth Org will have to do something to improve its performance and compatibility testing! :evil:

Thank you for your kind reply.

Whenever I receive a call, it is automatically transferred to my SE BTH-60 headset, so I am using it handsfree mode actually. I can accept/reject the call thru the headset.

Handsfree profile lets you use the automatic feature, which automaticaly accepts and answers (after a you specify the number of rings) the call without pressing any button on the bt headset.
Also, the handsfree profile lets you use the voice dial feature by activating it from the bt headset and without touching the mobile phone. and other features...
Does, anyone have any expirence with new nokia clip-on bt headset and the xda2.
Thanks

Sirs, I believe the time has come for me to beg the great one "TOWA" to write us a new doohicky, to make the xda 2 work in handsfree profile with handsfree bt headsets and others.
So, Towa, if your reading, have you ever had someone to beg you for something in writing?? :lol:
Must be nice bieng the man!!

Bluetooth headset problem

I have only had my XDA 2 for a week and I can’t get my Motorola 810 head set to work. The XDA finds it and tells me that it is compatible with headset profiles but it doesn't seem to work. Can anyone advise me?
Thanks
Andy

Have you followed the procedure for pairing the device,ie: place xda in discover mode, when it finds the headset, tap then enter code for pairing, once paired switch bluetooth to on, then make sure you have bluetooth headset turned on from the main/today screen.

I seem to have problems with my bluetooth headset every once in a while also. I have a HBH65. On ocassion, the connection doesn't seem to be working even though headset is enabled and they are paired. I've found that if I soft reset the XDA2, that the bluetooth headset will work again.

Have you installed towas bluetooth tools patch, this fixes a lot of problems with bonding and alos makes things work where they couldnt before. I was told that the latest rom release here in UK was going to address all these problems too but I havent got around to upgrading yet, I hope it supports full headset profiles so I can originate calls from the headset as well as answering the call.

I have downloaded the new Rom update and it seems no different. I have tried a soft reset and this did not improve the situation.
I know the headset works fine as I use it with my nokia handset with no problem.
Has anyone got a Motorola 810 that works ok on the XDA ?

did the bluetooth tools patch support voice dial from bluetooth headset? if not did anyone know the new rom from O2 works with this function? thanks!

Andy, no it doesnt support originate call from headset but it did allow lots of different gps and headsets to work, the headsets work for answer call/drop call only as far as I know, in the notes for the xda2 upgrade it mentions the headset profile but I dont know if anybody has hot the headset facility to work yet, I havent upgraded yet so I am yet to test it.

I have installed the new ROM and as far as I can see it does nothing for Bluetooth beyond fixing some compatibility issues on some headsets. It still only allows one headset profile (so if you have a headset and a handsfree kit as I do you need to delete bonded pairs when you change devices - now there's intelligent functionality!!). No headset dialing so still not a complete BT headset implementation. No handsfree support.
Anyone else think that the XDAII is a great PDA but about the worst apology for a GSM phone in the last 10 years?
If anyone can point me to a decent set of BT tools to add on let me know.

Not really.
I fully agree the XDAII is a poor phone, with the best agenda and contact list available, but that is!
I wonder if Phone-pda makers are really going the so called "convergence" way.
To date, and after many different PDA/phone/PDA-Phone devices I've tried, no one is even close to the mark.
Something so "simple" such as merging an OLD Ericsson (or Sony-Ericsson) T-68 phone abilities, with just a PPC 2002 (yes, not even 2003) PDA, should produce a combo, no machine on the market is even close to.
IT'S SO DIFFICULT?

HT820 Wireless Stereo Problems

I have an O2 XDA Mini S (Wizard) and have just purchased a pair of Motorola HT820 Bluetooth headphones. I have paired the two; however, I only get the Hands Free service (which works) but NO Wireless Audio. I have seen a lot about A2DP Hacks to get these devices working correctly, but shouldn’t the BT headset offer a wireless stereo/high quality/A2DP profile when you pair them?
Is the ASDP Hack the only way to get Wireless Stereo?
Any help with this problem would be very much appreciated.
Thanks, Harold Clements

You have not provided enough information for anyone to help you.
Some Roms have A2DP working without any hack.

To be truthful, I know very little about what I am trying to do. All I know is that I can’t get the music side of the Motorola headset working.
As I said in my previous post: I have an O2 XDA Mini S (Wizard) and have just purchased a pair of Motorola HT820 Bluetooth headphones. The two paired but I only get the Hands Free service but NO Wireless Audio. I clicked on Motorola HT820 and then went ‘Refresh’ and up popped ‘Headset’ so I ticked that and saved. I then clicked (and held) on Motorola HT820. The options that I get are Edit – Delete – Set as Hands Free. I think I should also have ‘Set as Wireless Stereo’ but I don’t.
I have read about the ‘hacks’ (zoad2p.cab, Tornado asdp, AKU2.6) but I am a) unsure if this is a solution to my problem, and b) what a hack is and why is it needed?
I just really want to know how to fix my problem.
Thanks for your help,
Harold Clements

Would you be willing to try a cab that i made? I dont have a wizard to test on and you seem to have the perfect requirements in which i need to test. If you are willing to try this cab would you please PM me your email address???
This cab is a variation of the zoA2DP and an idle thread process (which works great on the hermes)
Also you will need A2DP to listen to wireless Bluetooth stereo... most provider roms do not have this feature, most cooked roms do..

Also, in addition to the MS BT stack, you'll want to give a try to the Widcomm BT stack. With eit has its share of problems, it delivers much superior sound quality compared to the MS BT stack and its CPU usage is less that that of the MS stack.

Thanks very much for your replies guys. The thing is I am new to this and I don’t really understand.
Correct me if I am wrong but if the Motorola HT820 Bluetooth headphones are compatible with my mobile device (as documented) then surly it should work without much hardship?

again... BLUETOOTH ISSUES

hello everyone!
i just got my first bt headset, its an anycom aris21.
the pairing with my blueangel worked like a charm, but after a day of useage, i noticed several issues i kinda dislike....
- i can not start a call (start phone) with my headset, when blueangel is not in PHONE menu! is this normal? can this be changed?
- how can i disable the phone's speaker (and mic), when using the headset? its pretty anoying to know, that the caller could be heard by bystanders...
- people seem to have problems hearing me! can i change the microfone volume of the bluetooth headset on the ba?
- how can i find out what BT stack i have?
- i have now helmi_c's WM06 installed, no changes to bluetooth made.
what recommended changes/updates/patches/... should i try for better performance?!
what to install for best results?!? is that BroadcomBT1.7 still the way to go? what cabs do I need?!
i know, that some issues have already been adressed, but things are changing so fast here, that i have problems being up to date about all issues! so forgive my ignorance and please help me!
i would be very thankful!!!

krz

Yeh, the Blue Angel is a bit strange with some bluetooth devices.

I have the following issues with WM6 on my BA, which did not exist with 2003SE:
1) When Bluetooth is active, the device turns on by itself every minute or so. I understand that this is a hacked "feature" to prevent the bluetooth from turning itself off. This is probably the most annoying thing about WM5/WM6. Is there any fix I am not aware of?
2) When I start from scratch and pair my carkit (Parrot), everything works OK, except that BA's sound putput, i.e. for Microsoft Voice Command, is coming from the BA instead of the car kit. This is too low a volume, to be clearly understandable in a car. With my Universal (also on WM6) this does not happen.
3) After pairing my Asus GPS, nothing works. If I delete all paired devices and just pair my Asus without being in range of the car kit, it will work. If both devices are turned on (car kit and GPS Receiver), none works properly.
I don't use my BA on a regular basis anymore, because I have my Universal, which works flawless. However, I see no paint in upgrading to WM5/WM6 if one ends up with LESS functionality than the original 2003SE.
The only feature I will be missing is the fact that no RAM memory is used, which means one does not loose everything when the battery drains.
Are there any tips to solve these three problems?
The WLAN "bug" is not really a problem: even with 2003SE I had to occasionaly start and restart the WLAN for it to work properly.
Cheers,
vma

@vma:
1. Well, not at the moment; maybe if someone who can play with the dll's can fix this.
2. I use a Logitech hands-free, and i have no problems.
3. No problem here using a NoBrand BT GPS receiver and the hands-free in the same time.
Overall, my BA work much better on WM6; its just my experience.

problems i still have:
- i can not start a call (start phone) with my headset, when blueangel is not in PHONE menu! is this normal? can this be changed?
- how can i disable the phone's speaker (and mic), when using the headset? its pretty anoying to know, that the caller could be heard by bystanders...
- how can i find out what BT stack i have?
- i installed that Boradcom stack 1.7 without having any succes in getting my headset to work. with or without patch1 and htcheadset! any ideas?!?
- what excactly is that HTC HEADSET ADDON ?
please answer soon, any help is very much appreciated!!!!
thx in advance,
krz

1. Same here; i think is my hands free set limitation.
2. I get the same using the Broadcomm stack; use the MS stack.
3. Depends; if you use Broadcomm/Widcomm, you have an "about" box; if you use MS, i don't know.
4. i get it working, but with audio in hands free AND speakers; annoying.
5. don't know, try Google.

What Bluetooth Stack you use ?
First, I use the existing MS Stack on Helmi WM6. BT GPS and Handsfree couldn't run at the same time.
Second, I use Broadcomm Stack 1.71. BT GPS and BT Stereo could run at the same time, but Hands-free function didn't run at all.
Give me a light please.

your bluetooth headset
A few of your problems could be from the bluetooth headset you are using now-- such as when people can not hear you clearly. I currently have a sound id sm100 bluetooth headset and it works flawlessly....although i still can not activate voice calling from it(it activates it on my BA so i have to talk into my BA and not my headset). It could just be your headset.

Yeah, Bluetooth in BA really sux... you have to choose your bt handsfree wisely, make sure you try it on BA properly before buying it... currently I am using i clip II mini, and it is giving me the same behaviour as shazzy84's

Well I found a way to solve the BTA2DP problem. It supports stereo & is just fantastic. you can find these by the following link http://www.teksoftco.com/index.php?section=freeware & this software works too http://www.trianglepowers.com/PPC/ViewApp.aspx?ID=52 (have to register to download). I prefer Teksoft freeware as I am using it. Sometimes it takes a while after a few toggle u get it right

Adventures in Bluetooth

Ok, I have the T-Mobile Tab, I have Skype and Google Voice working via 3G and Wifi but here is the issue...
I have tried 4 different wireless bluetooth headsets and they all react the same... They connect and pair with no issues BUT...
When you place a call the other callers voice is routed, as it should be, to the BT headset, however, my voice is not routed through the BT microphone and it uses the Tab's built in mic...
This is pretty unacceptable as you can imagine and pretty much defeats the purpose of a BT headset...
Any ideas, thoughts, or help on how to get the Tab to route voice via the BT headset as opposed to it's built in mic would be MUCH appreciated!!!!
Thanks in advance!

This was kind of discussed in another thread. Current thinking is that they modified the profile to not support a mic on the BT headset.
Until someone creates a patch, update or a custom rom, there probably won't be a solution.
This is the price we pay for getting the new toys right away. Once the dev's start rolling out the mods, I am sure it will be corrected.

Whilst this may be true for US Tabs, FWIW bluetooth headset profiles do not work with Skype on Euro Tabs either.
I've been trying it out this afternoon, and whilst my headset (well, wristset to be totally accurate) works fine for regular cellular calls, when I try to use Skype I only get audio out.
If I check the options for the connected device in the bluetooth settings, I have both Media and Phone profiles checked. If I uncheck Media, I no longer even get audio out with Skype (though regular phone calls still work ok on the headset), which shows that Skype is not using the Phone profile at all.
So, I suggest you look at the options for your bluetooth device to see if it even has the option for Phone. If it does, it seems that the headset profile is still there and it is actually Skype which is not using it.
Regards,
Dave

If you read some of the comments here, it seems that Skype for Android doesn't support bluetooth anyway.
Regards,
Dave

Thanks for the info man. I'll check it out on my Sprint GT.

Wonder if it's possible to put the Samsung Galaxy S BT on the Tab?

It is because the sound of these apps is being routed via the A2DP profile and not Headset provide is you are hearing the sound via the BT headset but the mic used is the Tab's

Since my headset didn't work with Skype at all with the Phone profile awhen I switched of the Media (A2DP) profile, I doubt a non-A2DP headset will help.
The problem is Skype doesn't use the phone profile.

I dont think its limited to skype either. I tried two other programs last night, neither one had working mic.
Sent from my SGH-T849 using XDA App

BT works just fine within Skype when using it on my MacBook Pro and my iMac.... The only issues I am having is on the Tab...

No BT Headset Profile in any of the US Galaxy Tabs
The reason that none of can use their Bluetooth headsets with a program like Skype (or better yet, Line2, which I am a beta tester for) is that the Amrican carriers ripped out the ability to use BT Headset profile. Now some headset (such as te Jabra Stone) uses Audio profile, so it will work with the GalaxyTab, but we definitely need someone to break that an hack in a great fix so that we can get Line2, install it on the Tab, then us Bluetooth Headsets to do our communcating. This because the best (and cheapest) phone/data device in the world at that point. Is anyone working on that?
