Can WMDC Bluetooth Sync happen automatically?

Hi, I'm pleased to say that setting up my TyTN II to sync via Bluetooth with my laptop running Vista's Windows Mobile Device Centre was a doddle. None of the nonsense I had before on WM5 and my Wizard.
However, it appears Bluetooth sync needs to be invoked manually each time from the TyTN. This makes this lovely feature next to useless.
With Nokia PC Sync for example, Bluetooth sync to a Nokia phone can happen whenever the phone comes back into range, or every 15 minutes if you so choose.
So, is there any way to specify this with Windows?

I don't think so at the moment. It's a problem within the Microsoft WM OS.
I too used to love my old Nokia 9100's capability to do this but with having so many connection variants on this unit (GPRS, WiFi and BT) Microsoft have probably opted for a safe solution.
At least with manual select, you wont have it running down your battery with lots of data traffic while its in your pocket/purse at home/work without you knowing!
Maybe we could pass this on to the Kaiser Tweak guys to see if it could be made selectable?
Worth a try!

Sure, can you do it?

Will have a go but my 'Street cred' is a little low here at the moment....
I hope one of the other patient dev guys may look at this and take it up???

your not alone
Check out these other threads. All describe different problems people are having (including mine - not being able to automatically re-pair with my car kit).
All seem to stem from the auto re-pair problem.
If a developer could help, that would be great.

No-one seems to have come to our aid with a new BT stack.

Many thanks.. I've looked at those and they are mostly concerned with BT connection to audio devices.. What we are looking for is an automatic polling of your device by Activesync over BT as PCsync used to do for the Nokia. The connection has to be initiated by the SW for it to work. Cheers anyway!

Sure, they are mainly about audio, however (at least in my case) the audio is perfect when its paired.
My main concern is exactly the auto polling. I can pair my device the first time to the car kit, but every time i get back into the car I have delete the pairing and pair it manually again. This is not how bluetooth should work.
I think this is very similar to the problem the author of this thread describes.

Yep, my BT audio is good and you never know, if we start looking at auto-polling of data/stereo devices we may cure a lot of problems on here..
Thing is we may have to go around the Activesync overide (which is the slowest block on this setup!) and use a priority connect to BT similar to WM5torage on usb!
What ya think XDA???

Yeah its one of the few things I miss about my Nokia 7710 was that i walked into my house and it would sync with my computer automatically. sigh

Its definately a WM/Activesync 'Non-feature' as when you first pair your device to an Activesync capable BT PC or laptop you get a pop-up message on the WM device reminding you to disconnect your BT Activesync link to avoid draining your battery!

Autoconnect A2DP when in range?

Hey Guys!
Is there a way to tell WM6 to automatically route Audio through A2DP as soon as a paired device supporting the profile is connected?
Clarification:
When using a Hands-Free-Headsetfor telephony you can pair it once, then turn it off, after that it is automatically connected to the phone as soon as you turn it on again.
In contrast to that a Bluetooth Stereo headset is not automatically connected, you have to manually activate it in Bluetooth Settings first before you can listen to music through it.
Especially with my car stereo used as "A2DP Headset" (which loses power every time the ignition is turned off) this can get highly annoying.
Is there a way to tell Windows to automatically "use" A2DP-Peripherals when available?

Try A2DP Toggle: http://www.teksoftco.com/index.php?section=freeware
The Today-plugin migt reconnect automatically, but it has a memory-leak...
To easily manually reconnect, you can create a shortcut to the exe:
\Program Files\Teksoft\A2DPToggle\A2DP.exe
Then you can put that program on your today screen easily.
And if you want a nice icon with that shortcut, you can change the shortcut file to:
53#"\Program Files\Teksoft\A2DPToggle\A2DP.exe" "-a2dp:1"?\Program Files\Teksoft\A2DPToggle\settings.exe,-0

Yep. The WM bluetooth stack sucks. It works better with some stereos though. I tried it out in the store with I believe a Pioneer (with bluetooth 2.0) and it was perfect. Turned it on and a2dp connects. Switch to another input and a2dp disconnects. Switch back to bluetooth audio and it connects. It was flawless. I ended up ordering the kenwood built in bluetooth unit (bluetooth v1.2) and it is terrible. I must manually toggle the bluetooth connection (I use a program that I wrote to do so, kinda similar to the above the above poster posted). Also, sometimes after a call comes in it wont reconnect. Sometimes i must power off then on the headunit a few times. Wasnt this thing supposed to make things easier?! A real shame because I love everyting else about the kenwood head unit. It works better with some ROMs on my phone (this is with a tilt; xperia on the way ).

Yeah, A2DP Toggle works for me as well, It's just dumb that this phone cant just do that itself. My old W880i could! I'm using a Sony DR-BT21G headset

A story to learn before you you buy the head-unit I spent almost an hour at Fry's to try many units w/ my Tilt as well (Sony, Pioneer, Kenwood, JVC ...etc) and ordered online w/ the JVC unit. Excellent sound (compare to other model) but disconnect after phone call issue exist. I believe it's HTC fault since my Eten M600 (MS BT stack) and Asus P525 (Widcomm) doesn't have this issue (but others....). But I got to admitted HTC one do have the best sound quality.
BTW, my JVC BT-1 will auto connect my X1/Tilt when I start my car and I think it serve my purpose.

Diamond and car audionavigation JVC NX7000 bluetooth problem

Hi all,
Need help with my HTC Diamond. As my Pioneer car navigation, with which the diamond bluetooth functioned well, was stolen, I was advised to mount a JVC navigation system NX7000 with a detachable front in order to prevent theft. However, the HTC bluetooth dysfunctions. It connects and pairs without problems, but when the diamond goes into sleep or is switched off, it is impossible to establish a phonecall using the JVC car-unit, although it indicates that blueconnection is still valid. When I switch on the phone, even minutes later, it will eventually do the call. If I force the HTC to remain powered-on it will function normally. I am sure that this has something to do with a suspend-mode of the diamond bluetooth part and that this can be solved by the right registry tweak. I tried several tweaks that I found on the forum already but without succes. I upgraded the HTC to the latest firmware 2.03 but no improvement.
I called with HTC and they said that they know the correct registrysettings but they won't supply them because of "licence restrictions"...........
Anybody the same problem? Somebody who has the solution?
Thanks

I have exactly the same problem! Incoming calls work fine, but like you, I cannot initiate outgoing calls from the JVC unit unless the diamond is turned on fully. I there's not a fix for this, I may have to go out and buy an iphone again after selling mine to get a diamond!

there is a fix but HTC won't tell. they suggested to open a thread on this forum in order to get suggestions on the matter. and so I did. When I subsequently asked them if they would post this solution on this forum they said they would not :-(

You may not want to fall back on an iPhone with the JVC NX7000. Not to go too far off-topic here, but pairing an single iPhone works great (once I figured out the overly complicated menus). BUT...it won't let me pair a second phone (of any kind). Once the first phone is paired, all pairing menu options are greyed out ("Search" and "Open"), thereby preventing any further phones from being paired. I first need to unpair the first phone before I can pair the second one. JVC Support is comically unhelpful.
Has anyone had luck paring more than 1 phone (of any brand) with the JVC NX7000?

You are the lucky one! You can succesfully pair one phone but it works

I don't care if I can only pair one phone. I only have one phone! lol.

Hey guys!
kind of the same problem here but with the Volvo built-in bluetooth solution. Actually when the device sleeps and I initiate a call it will take some time, then the device will turn on and it will begin to dial but drops immediately. When the device is fully turned on there is no problem at all. Incoming calls work just fine. Even though it first rings on the phone and after a second or two it will ring in the car and the device will stop ringing. Which confirms that bluetooth sleeps somehow and only connects fully when the device is fully awake.
It really looks like bluetooth goes to sleep, so we need a solution which keeps bluetooth awake even if the device itself is in sleep mode.
Patrick

Exactly the problem I described. It's a sleep or suspend mode of the bluetooth that causes the dysfunction. I can pair nokias wih JVC without any functional problem, they work like a charm. It is really a HTC related problem, I tried a lot of registry tweaks suggested for similar problems in other HTC devices, but no luck so far.
Reply to Guitartng:
storing multiple bluetoothdevices in the JVC for subsequent use can be done by selecting "new device" and then go to "bluetooth setup".

Exact same issue with a Kenwood DNX 8120 double din unit.
If anyone finds out the solution, please post it here. I'll keep searching.

Good News Lads!
Well after blowing my head of trying different roms and radios got a solution.
The solution comes from JVC stereo and not from Htc diamond Phone!
You have to set special phones To Samsung E520 and then pair device with the htc diamond. It works like a charm, know I can make calls through my JVC stereo and NO MORE deep sleep of htc diamond.
Try with samsung, it work for me, if not try with other phones in special phones before pairing!
Cheers!

I just wanted to let you know that I also was able to fix my bluetooth issue by flashing stock firmware 2.03.405.3 WWE with Radio 1.09.25.23. I was previously using Dutty's V4 which is based on 2.03 afaik, but it look like Dutty tweaked something on the bluetooth stby behaviour.
Anyway, it works like a charm now and the whole calling and answering process is also much faster!

Bluetooth - Auto connect?

i've paired a few things (bt headset, parrot car hands free, computer) but it won't automatically connect to anything. i have to manually tell it to connect. is there a setting that i'm overlooking, or a tweak to allow this?
thanks.

Yeah I noticed the same thing in the car today. Maybe because of whether it is discoverable or not? When you turn that on it only does 120secs. I haven't played with it, but i sure hope it can auto connect, or at least with froyo.

It auto-connects to my car, but not to my home phone. I think that's because the car itself initializes the connection... Would be nice to figure out how to fix this, so I wouldn't have to connect manually every time I come home.

in my '10 Genesis Coupe, I cannot get it to auto connect, even though i reset it two times and checked "always allow." This is the first phone this has ever happened with, every other one auto connected (HTC Touch Pro2 with winmo 6.5 AND a hacked android 2.0, htc hero w/ 2.0 and 2.1, n1 w/ 2.1 and 2.2, and a feature samsung phone) so I know its not the car.
Any more ideas?

What I figured out is that auto-connect on this phone just doesn't seem to work at all. The only time it auto-connects is to my 06 Acura when I start it and only if it's not already connected to anything else. But that's because when I start my car, it's the car that initiates a connection, not the phone. If I'm connected to something else (like my home phone, for example), when I start my car, and drive off, Bluetooth connection to my home phone will get dropped after I get away for more than 100 feet, but it will never connect to my car after that. And it never connects to my home phone on it's own. Very painful!:-(

My Captivate will automatically connect to my Parrot hands free device when I get into the car. I don't know which device is pushing the connection. However, I also have a Miccus BluBridge Receiver in my car plugged into the Aux jack. This device doesn't auto connect.
To get things working I have to go to the home screen, settings, wireless, blue tooth, then click on the device. A friend of mine was talking about Tasker as a possible app to use, but I don't really want to spend the money on it until I know it will do what I want. The other annoyance I have is that speaker, headset, and bluetooth volume are all the same. It looked like Tasker would solve my second problem, but perhaps not my first. Has anyone else investigated this?

Bluetooth auto connect
I too thought I had an issue with this. Mine is now working OK most of the time. One thing I discovered is that if there is more than one BT device available the phone sometimes will not connect automatically.
I wonder if this has to do with the fact that it will not connect to more than one device at a time. This is big downside for me that I hope get corrected (but please GPS first)

It won't conect correctly because there is no setting for always visible. The handsfree device searches for your phone to initiate the conection and if it can't see it it won't try to conect.

I also have a Genesis Coupe 2010 (3.8 in case you care) and my vibrant connects just as well as my TouchPro2 and my Nexus One running Foyo.
The Nexus One stock 2.1 never worked, reconnecting every couple of minutes.
My first Vibrant (same as captivate) did not work well either. I expected it was because the BT stack in Eclair did not support car profile, but after I exchanged my Vibrant due to a rattling volume key, it has worked very reliably with the GC'10. It autoconnects ad soon as I turn on the engine, without having to do anythong, followed by "transfer complete".
I leave BT on all the time. My phone is not rooted or modifief in any way, running stock software for everything.

That is not true and it is not necessary, not even during pairing, ad the connection is initiated by the phone. Once passkeys are echanged, visibility is not required.

What firmware do you have on your GC? Have you deleted all phones?
Things to try:
Delete all phones from the car (setup/delete all phones)
Restore the phone to factory settings.
Upgrade the car's radio/BT firmware (see dealership for details or try gencoupe.com)
Call ATT support (?)
Wait for froyo
Get used to
Return/sell the phone
Hope this helps

Never had the problem with any of the Pioneer radios we've had, and my Eclipse doesn't have that problem either. To be fair, I've no experience with MB cars, but that shouldn't be the case.
I know with my Eclipse HU, I had to initiate the connection while in the phone menu otherwise it would connect for BT audio but not for the phone. After setting up the phone it will connect as its supposed to regardless of what input I'm using.

just as an update to my initial problem... my parrot system in my car auto pairs all the time now (it just takes ~30-45 sec to do so), but the phone still will not auto pair to bt headset or computer...

I don't think its supposed to auto connect to the computer. I think its a need based connection.
And on that note, when i send a file my phone does connect. I don't use a dedicated bt headset so i can't talk about that unfortunately.

When you say 30~45 sec, does it mean from powering the car up until BT is usable through the car system? That's is normal and the duration depends on how many contacts you have in your phone book and how many phones per contact. Mine take about the same.

I agree. It is only supposed to autoconnect to devices that support the handfree profiles, if the handfree profile is set as default.

I tired turning visible on right before i started the car and it connected no problem. Really annoying. I have a pioneer as well. Too bad you can't set it to visible always. Other than that it works much better than it did with the Fuze/Any WinMo phone. Never had a phone that worked right in the car, except for my GF IPhone, works great.
I hope it works better in Froyo.

[Q] Bluetooth Connection Issue (Redux)

Hey All,
I've done a quick and dirty search for this problem, but I haven't found anything that's exactly the same.
I have an XT1060, Dev Ed, on KK 4.4.4, and I'm just wondering, am I the only one who cannot get my bluetooth radio to hook up to paired devices easily?
The problem is, I always have to ask to connect manually; this is a bit of a pain, especially after turning off my car, say, for a few seconds. Oh, it'll connect, but sometimes it takes 10-15 tries before that connection is made, and even then, it's often after I have to disconnect then attempt to reconnect a few times because it doesn't connect both the phone and media modes.
I have done the unpair/re-pair thing a couple of times, but nothing changes.
I had an HTC phone before this, and it'd reconnect automagically to my cars BT server, so I suspect it's nothing to do with the car's BT radio. I really miss that...
Thanks for any suggestions anyone might have in how to remedy this. Fwiw, I'm willing to go through a diagnostic procedure if someone would clue me in to just how to do that.
cheers,
john

I've had issues with the bluetooth and pairing. When I was on 4.2.2 (I think..) it wouldn't connect automatically at all, and I used an app to connect for me. I have a Chevrolet Cobalt and it wouldn't connect to my built in bluetooth for calls or a small bluetooth dongle that I use for playing music through the AUX input on the stock radio.
https://play.google.com/store/apps/details?id=org.myklos.btautoconnect&hl=en
Once I was on 4.4.2 it seemed to work much better. I have no real issues now on 4.4.4. The only time I notice it not really working right is when I try to connect to the bluetooth speaker in our bathroom at home. If I turn the speaker on, it almost always connects to my girlfriends phone nearly instantly, even though I open the bluetooth menu and tap the paired device to manually initiate right when I turn on the speaker. It usually takes me a few tries to get mine to connect before hers, or I ask her to shut her bluetooth off for a moment while I connect. She uses the speaker every day because she leaves for work after me, so it only happens to me 1-2 times per month on the off chance that I want to listen to music or a baseball game in the shower, so it never really bothered me much.
I think the bluetooth radio in this phone could be better.. I never had any similar issues with my Droid X or Moto Razr Maxx so I'm not sure what the deal is...
Edit: forgot to mention I also have an XT1060, but not dev edition. My bootloader is unlocked and I am rooted, but using the official 4.4.4 VZW rom with Xposed.

I have never had any issues pairing Bluetooth - on either my car or moto 360 watch (even simultaneously).
However, I have noticed that the Bluetooth connects much quicker on custom ROMs when compared to stock.
I think tour connection issue may be a setting or rogue app related.

Fwiw, things have not gotten any better since I posted my question. I'm getting more accustomed to it, though.
As for the possibility of a rogue app, yes I suppose so, but short of uninstalling everything, and adding them one by one and trying to connect to something via BT, how can someone go about debugging such a thing?

You may need to delete the profile for the Bluetooth pairing in your car. Could be a conflict there.
Otherwise, try looking at your Bluetooth settings on the phone.

Is it *ALL* bluetooth devices, or just the car? What model and year car? Are you connecting to the Hands Free profile, Headset Profile, or doing something like A2DP for music streaming?
How long have you had the phone, how long has this been a problem? Has the symptom ever changed?
Keep in mind, just because your HTC phone connected to the car just fine, doesn't mean the car could not be the issue. While the Bluetooth profiles and protocols should be "standard" I've seen many issues of interoperability issues between bluetooth devices over the years. Especially with car kits.

Guys, thanks for staying with me on this. One thing I've definitely learned is that the bluetooth thing is something I'm pretty ignorant on. I can see that I'm going to have to study it a bit before too long. Gad, that HTC spoiled me rotten---at least in that way.
I haven't tried the phone with any other BT devices. This is mostly because I don't own but two, the car and a travel speaker, and I haven't had the speaker out of its case since I scored the phone six or eight weeks ago. Also, I did some housecleaning, so I have only a small fraction, maybe 20%, of the same apps on the MotoX that I had on the HTC. I have no apps on the MotoX that I didn't have on the latter.
As for some of the car-related suggestions, it's a 2015 Subaru Forester Premium 2.5i, which is really only level up from the base model of that line. I can't find that there is a bluetooth profile setting in the car that I can change; I think that it's too basic. The relevant user manual simply states the following:
Media format
Bluetooth audio devices cannot be
connected if they are not compatible with
the following Bluetooth® profiles.
. A2DP (Advanced Audio Distribution
Profile)
. AVRCP (Audio/Video Remote Control
Profile)
I don't even know what either of those mean!
Anyway, what I did do is go to the phone settings, and uncheck the Media box that shows up once the car's BT server is detected. Then I try to connect with the Phone box checked. It'll still fail to connect several times, but (a) it doesn't take as long to fail to connect, (b) it doesn't take as many tries (it seems) to make the connection, and (c) when it fails, it fails totally, so I don't have to disconnect from 'Media-only Connected (No Phone)' connection. That makes it easier I suppose. Then once the connection is established, it's a simple matter to go back to settings, and check the Media box. That add-on connection happens pretty quickly, but the process is still a little overwrought, imo.
Of course, KidJoe, up until you mentioned a Headset Profile, I didn't know one existed. But when I try to play music on my phone using PowerAmp, well, the app doesn't hook up to the BT anyway. That's a key difference between the HTC and the MotoX. In PowerAmp, I have "Play over Bluetooth on Detection" selected. The headset isn't being detected at all. So maybe that goes some distance to explaining what I'm encountering.
Again thanks to both of guys for hanging in there with me! I'll keep trudging "onward through the fog," as it were...
cheers,

A2DP and AVRC are used for Bluetooth Stereo audio streaming (like playing Pandora on your phone via your car stereo). Not phone calls.
For phone calls, usually a Headset or Handsfree profiles are used, and sometimes BT Phone Book Access (so you can see your phone's contact names/numbers on the car's screen).
I've run into compatibility issues between some phones and some Headset/Handfree devices (mostly cars, but a few bluetooth headsets too). Often times when this happens, you're stuck. Each side will blame the other (i.e. Moto will blame the Subaru car stereo, and Subaru will blame the phone).
I have had issues re-connecting to my car (a 2011 Saab 9-4x with Bose/Nav), IF I had my Moto S11 Flex HD headset connected to my Moto X before I got in the car (even if the S11 was powered off/disconnected from the X before I started the car). Usually toggling the X's bluetooth off/on, and sometimes worst case rebooting the phone, has always fixed it.. Another time I had troubles connecting to my Saab's car kit was when my wife was using her phone to stream audio. The next time I got in the car, I had to manually connect my phone. The car always tries to connect to the the last phone used, so it was looking for my wifes and it took a while before it timed out. When it did time out, it didn't look for mine.
Since you have a 2015 Subaru, I would consider visiting your car dealer, ask them to help with pairing the phone properly, and making sure its working right. See what they have to say.

My bluetooth in my car stopped pairing the other day, and it turns out it was an app that updated and requested permissions related to bluetooth. I didn't notice them because it's an app I trust so I accepted the new permissions without really looking at it.
I used App Settings (Xposed module) to disable the permissions and my bluetooth works fine again.
I could still pair with things if I went to the bluetooth paired device list and manually tapped on the device I wanted to connect with, but it would not pair automatically (like when I got in my car). Once I disabled that permission, it started working again without issue.
May be worth a look through your installed apps to see if anything has access to bluetooth and may be interfering.

Hey All,
Thanks again for the continued help!
It's true, I didn't do any research on app interference before I posted this thread topic, but since a couple of you have brought it up, I decided to do a little research. I installed a permissions app, and took a look at the permissions that allows an app to automatically seek out, and pair with, Bluetooth servers. I have to admit, I got some surprises there. (Who would've thought that Beautiful Widgets needed that permission; it is now gone.)
Anyway, most of the remaining apps are either system/Moto-related, or ones I would really like to keep. I'll report back on what I learn. If there are other permissions that I need to reference besides the two pairing-connecting to Bluetooth ones please let me know...
cheers,
john
