[Q] [DEV REQUEST] Bluetooth stacks - HTC EVO 3D

I know the devs here are working feverishly on new roms but I have a small request that I know sounds like I am asking a lot. It appears the bt stack in the 3d is kinda screwy. What I mean is when you connect to bt stereo its static and when trying to connect to the bluetooth of my GM car it doesn't want to stay connected and wont connect right. I am curious if someone can pull the bt stack from a known working like the evo or the mytouch 4g (both htc phones) and try that out. Just a thought and could help a lot. HTC acknowledged there is a problem but blames it first my car (which every other phone works perfectly on) and my bt speakers (which every other phone works fine on). So it doesn't look like their going to fix it.

My phone works great on my stereo headset, and in all the Hyundai cars I work on (for calls and for streaming audio). Dealing with blue tooth complaints on the cars I work on, I will say that one phone model will work when another won't. So it may be compatibility issues between your phone and car.

That's why I need the by stack from a known working phone thrown in heh. By hardware is the same for the most party but software can be different.

Also for WiiMote
I too would like to know if it's possible for someone to bake in a new bt stack because WiiMotes don't work on the 3D and that's a major part of why I wanted the device (MHL + Wiimote = portable entertainment system)

[Q] Bluetooth in car auto connect issue, major anoyance for many

I know there are a variety of posts of many flavors in regards to OEM in car bluetooth handsfree systems. Some for unbranded i9100, some for the AT&T i777
For anyone out there with the knowledge: Is there anyway to find a task automater (like a macro) to lets say automatically activate the bluetooth button for the paired device, lets say 1 second after Bluetooth turns on. In connection with Auto Bluetooth app (like the ones which turns on when motion is detected) it could be automated. I would do it, except I don't know how to write program code.
I am thinking like "if bluetooth turned on, wait 1 second, trigger paired device input" . Because in that case it would connect (automatically) in most cases I though many many people posting around here.
Anybody any idea?
I am trying to connect my Galaxy S2 with they system in my 2011 Jaguar XJ. I never had a problem with my BlackBerrys. The BlackBerry autoconnects the moment I start the car and all functions work.
Absolutely not so with my S2. It seems that differnet car manufacturers differing systems which use BLuetooth differently. Some work, some don't .
Let me clearify the problem. Phone does NOT AUTOCONNECT and it drives me nuts. Before i just got in the car and never pulled the phone out of my pocket. Now I have to pull it out and manually connect.
I am posting as I may save some of you some time. I tried everything up and down the list. About every Bluetooth apps in the market place. Free or paid. Really pretty much all of them. Nothing worked. I upgraded to the (leaked) UCKJ1 and back to the original UCKH1. I rooted and unrooted.
To no avail. All I can do is use a shortcut widget to save me a few menues to navigate.
So for the ones with the same problem; you know all the things I tried. Don't waste your time.
It takes two devices to successfuly connect. If a connection doesn't happen, you can't blame just one device. My ISGS2 auto-connects to all of my devices (AV receiver, headset, PC, car, portable speaker, G-Tab) automatically every time. I get you're upset, but you can't single the phone out alone. As for cars, in the ISGS2 forum, non-iDrive (older) BMW's were the majority of the problem.
Same here. I have no problem auto connect to my BT devices. But when it comes to BT auto connections, problems are common. Both sides of the BT connection can be the cause.
Well depending on the year, make and model of the car with bluetooth. Really need more information. What Barry said is oh so true and usually anyone can tell you what their experience is. My experience with my daily driver's system *Alpine CDA 9887, Alpine KCE-BT400 made by parrot*, works flawlessly. The only time I ever had to manually connect was right after getting my sgs2 and even my captivate connected properly unless I was connected to my jawbone icon when I jumped in my truck.
HTH,
Charlie
Mine connects flawlessly in my 2010 Camaro SS.
Im in a 2011 Camry SE, and with stock ROM it connects automatically. With CM7.1, I just have to take it out of sleep, by turning on the screen, and it connects. Not a big deal.

Hi, Thanks to all for the responses. I completely agree that it takes two devices to do it right and I am fully keeping that in mind. I have 2 more cars I can try with. So I will check if it works with my wife's Lexus and with my Clarion system in another car I have.
It just is, that my BlackBerry (which I don't miss at all) simply did the job perfect. Obviously I can't tweak anything on the car side as that is next to impossible. There is no open source code and all is so proprietary.
So the only hope I have is to figure out a way to teach my SGSII.
Again thanks for the input. I do absolutely LOVE my Galaxy S2 (i777) therefore this is a simply irritating that I have to push buttons when I get in the car.
Hearing that it works for most of you is well, good for you and not so good for me.

Well, I will experiment a bit more and I will share what I will find in case others have similar problems.
This reminds me of a blog post ages ago called "Bluetooth needs a dentist"
The state of Bluetooth compatibility is abysmal in general... What is exceptionally sad is that 4-5 years ago or so, one of the most relibale and compatible Bluetooth stacks around (BlueZ) got a bunch of nastygrams from the Bluetooth SIG regarding failure to run the "offficial" compatibility/interop tests.
The short summary: Bluetooth compatibility is an epic nightmare, on both sides of the coin (host and device).

Hello,
I have to fully agree with Entropy512. Bluetooth compatibility is a disaster. Especially after all the years around. Not sure who, what and where is deciding on BT specs, drafts and so forth.
I know that with car systems it is a hit and miss. But it doesn't have to be. We all know that. I was digging on my good old Jaguar forum. What I found confirms exactly what we are saying.
Earlier Samsung Androids barely could hold a connection on Jaguars systems. Just with later versions and Gingerbread that was resolved. And none of the Samsungs autoconnect to any Jaguar system. And that is the same for Audi, Merceds and Subaru and probably some others. According to the Jag forum Samsung knows about this and worked on it.
But here is the main problem. On my wife's Lexus and on my Clarion head unit in my van it works like a charm. Automatically connects without a hitch. I understand Samsung can fix that but than it may not work on other cars. But how come BlackBerry was able to do what the Samsung unit can't???
And yes, some features like phonebook, direct dial and so forth are totally hit and miss. How do car unit manufacturers test? With what? Just one phone from 3 years ago? Same with the phone manufacturers. Is anybody talking? Seriously, why can't car head units manufacturers and phone manufacturers not figure out how to get on the same page? Car BT is becoming a standard equipment. So do BT enabled phones, no matter smart phones or what have you. There are not that many head unit manufacturers. So they can't agree on a standard which then can be used by the devolpers for a decent BT stack for phones? Completely ridiculous. Can make phones talk to you like the Apple Siri but can't get a bluetooth connection.
OK, I got that off my chest. Now I will try to get to work. All I can do is working on the i777 side, because there is no acces to anything on the Jaguar side.
Funny thing is, my phone is always stating phonebook request when I get in the car. Eventhoug I turned phone book off in the car. So the phone "hears" the car. Just without hitting the profile for the car it won't connect.
Auto connect to my Mazda 6 no issues. Same with all my other phones.

Do you have problems with the Mazda taking too long to switch from "Music" mode to "Headset" mode, thus the vlingo voice prompt timing out? My mazda has that issue and it makes vlingo in the car pretty much useless.
I don't typically use voice commands but ill try. It has no issues taking and making calls then going right back to google music streaming.

I am also experiencing sporadic problems with my SGS2 and 2011 VW Golf using BT. About 75% of the time, it auto-connects fine when I start up the car. The car lets me know it linked and I can make/receive calls through the car's BT system fine. Address book loads as well (though does require a secondary authorization on the phone the very first time you use it).
However, every once in a while it either can't "find" the phone, or goes into a continuing looping state of "paired/not-paired". Generally when I actually want to use it! When it can't find the phone, manually searching for it (on the car's system) usually rectifies it temporarily, but it may go to unpaired a few minutes later. And on occasion, it simply can't find it at all. When I reboot the phone, or disable/re-enable BT on the phone itself, this problem usually goes away. This makes me think it's more of an issue with the phone then the car.
I too came from a BlackBerry torch and never once had a single pairing problem with my car.
When paired, media streaming generally works well, but occasionally I have to stop/restart it a couple times in order for the car to 'see' the media stream and allow me to chose it as the input.
The problem that I have is that the sgs2 will not report signal level to the car, so the car always shows full signal, even if i have no signal.
And it doesn't connect to the car unless the phone is in the car when the car starts. If bluetooth is turned off, or if I leave the car and go out of range, I will have to open the settings and force a connection.
Problem Solved, Autoconnect now working
Problem solved, read on:
This seems to apply to a variety of other vehicles, namely Jaguar, Mercedes, Audi, some BMW, Nissan and Subaru.
You can get your phone bluetooth auto connect to your vehicle by trying the following:
Attention, I believe this works for rooted phones only.
Get a app such as Titanium Backup Pro or MyToolbox.
under System Apps freeze "Bluetooth Share".
Now my phone automatically connects to my Jaguar XJ and all features seem to work. Having gotten around to check the phonebook yet. But all recent number log show and all seems to work.
Attention: I believe that may only work for rooted phones.

I'm going to try this...
I've been having trouble with it automatically connecting to my 2011 WRX. My iPhone 4 always connected immediately, no problem. But the GS2 has yet to automatically connect, ever. It is paired fine and if I go into the Bluetooth settings, it is paired OK and I can manually tell it to connect. I've tried deleting the connection both from my head unit and the phone and recreating everything multiple times. Still no luck.
I'll try this and report back.
Bluetooth is def one of those technologies that could be enormously awesome but often has so much "fussiness" with it (due to incompatibilities or quirky behavior between varying BT devices) that it can easily become a right-royal PITA, IMO.
I've had quite a few Android phones over the years, now, and tried running both stock OS and many different ROMs on them with one of the expected primary functions of my phone to be as my main music player, including streaming music via BT/A2DP to my car stereo and this one function has ALWAYS proven to be the most frustrating experience. So yeah, I'll fully agree that whomever is "calling the shots" with setting up guidelines and specifications for BT and BT-based devices needs to get themselves an iron fist and put an end to this crap of inconsistent behavior and general flakiness.
When I got my AT&T SGS2 I was shocked to see that Samsung had done something to enable their stock music app to be able to transmit song metadata via BT. Android thus far has only supported AVRCP 1.0 (AFAIK) while you need AVRCP 1.3 (or higher) to be able to have metadata transmit over BT. At first I was ecstatic that FINALLY I could see my song info from my phone displayed on my car stereo while connected via BT. But then I found out that with the SGS2 and the stock music app my car stereo could no longer successfully send play/pause/forward/reverse commands to my phone! D'oh!!!
So then I went back to Poweramp (what I had been using for my primary music app on my previous phone; a Nexus S) and of course it wouldn't display the song metadata. But the big shocker was that it also couldn't recognize control commands issues from my car stereo! Not cool!
I did much tinkering and research and finally found that the music app PlayerPro would successfully work with my head unit (but still no metadata, of course) and so that's where I'm at.
Ridiculous, IMO. Nobody should have to endure such frustrating behavior with BT devices. I really wish somebody could straighten this kind of mess out in regards to Bluetooth and get things to "just work".
No luck for me. Freezing the Bluetooth Share did not fix my auto-connect problem.

OK, you can try one more thing;
Freeze all of those files: BluetoothPBAP, BluetoothShare and BluetoothAvrcp. If you have any other entries you can try freezing them, too. Just everything EXCEPT anything with a name like Brcm or BrcmBluetoothServices.
Just try it. And MAKE SURE to wipe cache after freezing, or better reboot. Also you want to make check they are in a "frozen" state after rebooting. I used "MyToolbox" and it worked perfect.
I haven't checked if I can still stream music, but I never use that anyways. I froze all of those and started unfreezing one by one. The experiment showed that in my case I only had to freeze the BluetoothShare. You may have to freeze the others, too.
Let me know how ot works. I am curious now.

[Q] Sprint Photon Bluetooth Issue

Well I have searched high and low and have not found an answer yet so here goes.....
I have a Pioneer AvicZ130BT stereo in my truck and I have just switched to a Photon from an EVO 4G. I am having issues with connecting to the head unit over BT. It will work some times and sometimes it will disconnect the phone and shut off the bluetooth on the phone.
Q. Are there any updated or legacy BT drivers that I might be able to try to get these two to play nice?
Q. Is there an App that might be helpfull.
Any help will be appreciated.

Are you running on stock?
I know certain rom/kernel combos are having Bluetooth issues. I am on cm9 with the original kernel and connect to my blau deck in my bimmer and a pioneer deck in my blazer no problem.

Yes the phone is stock but has root through the All In One Root just for hotspot. The phone had issues pairing in the parking lot of the Sprint store but I thought I would be able to work it out. I have tried just about everything but can not get the phone to connect automatically or consistently.
My EVO worked perfectly. I spend alot of time in my truck and this will be a deal breaker if I can not get the phone to play nice with the truck.
I have been having similar problems with my Bluetooth. My keyboard disconnects randomly and my headset often disconnects. I posted a question about updating Bluetooth stack, but no answer as of yet. I did try cm9 and the keyboard seemed to work better. However, i didn't use Bluetooth nearly as much while on cm9.
For me not a deal breaker, but i am hoping the motorola update to ics will fix things.

UPDATE
Just wanted to say that the phone is connecting very well now and seems to be streaming Pandora and other audio just fine. I did download some 3rd party apps like bluetooth manager and car dock settings that do help in configuring the connection better. I also think that I may have been a little impatient waiting for the phone to connect automatically and may have been causing more issues than the phone. My Evo connected very fast and this phone is just a little slower but I can live with that. So in short, the phone is working as it should and I will stay a SexyMoPho for a while longer I think.
Thanks to all
What did you do?

YMMV:

This nukes your Bluetooth (bluetooth daemon) stored settings. Handy if you've dirty flashed any ROMs.
I found this here:

Edit: In the interest of due diligence, I have to add that there was also a firmware update for my Pioneer DEH-80PRS. Between nuking the Bluetoothd settings on my Android and updating the Bluetooth Firmware on my Pioneer car stereo, I have had flawless operation ever since. Pioneer has a disclaimer that if you don't have an IPhone, you don't need this update... I think they fixed something they aren't admitting to. You see this often with big companies that throw things in under the radar.

Bluetooth crashes when trying to connect headphones

I have a pair of Motorola S305 headphones and they absolutely will not connect to either of my Flyers. One is running LeeDroid and the other Cool Honey. The tablets see the headphones but will not connect. When I try to click on the headphones under "Paired Devices" I get "The application Settings has stopped unexpectedly"
I am pretty new to Flyer ROMs so I am not sure if this is common or if there is a known fix. It is a major issue as my fiancee uses these headphones to watch video on her commute.
Any ideas? Thanks

Nope, not using it as a phone, just as wireless headphones.
I don't have the tablet in front of me but IIRC one of them IS on LeeDroid 4.3.

Yep will do tonight.
I have S305 headphones too, and I just got my daughter's Flyer back from HTC with stock Honeycomb. I will try to connect my headset and let you know.
No connection problems with stock rooted Honeycomb here. Connected fine, was able to adjust volume, skip tracks, and pause using the headset controls while listening to Google Music.
I have also learned not to mod the Wife's electronic devices... that is why she now has an iPad and iPhone 4s and refuses to let me touch them. She used to have an Evo 4G and called me from work one day because her "customized" phone was in a bootloop and I had to walk her through recovery to flash a stock rooted ROM. She was not happy that day!

Bluetooth a2dp stuttering issue

I just bought a Sony MW600 bt headphones and it seems that there's a terrible stutter when i try to listen to anything. The only fix is to turn off WiFi. Anyone else experience something similar? I am forced to turn off wifi everytime i wanna use this, which is kinda annoying. Please tell me it's an android bug that can be fixed with some hack

FWIW, I have the same issue, although eventually it seems to settle down to one-two stutters every minute or so. Sometimes it is really bad, though.
It could be hardware... my original Inc. did not have this issue. But my old Touch Pro 2 did do something similar if WiFI was on.
I have the same issue with the BT in my car. Can't use the hands-free in the car & streaming music is unbearable. Are either of u running custom roms?

I never meet this kind of problem in my HTC phone with MW600 BT headphone when I listen to mp3 music and browse facebook in the same time.
Is it possible that your WIFI AP signal is too weak to affect BT? I heard that BT and WIFI shares some common resource in HTC phone.

Using stock ROM (rooted, but nothing more than that), playing local music using the stock player. Doesn't seem to matter if I am connected to WiFi AP or not.
I don't want to muddy the waters on this one but I wanted to mention some things that have happened to me with several phones over the last few years. Thunderbolt....BT headset needed to be replaced as it had no outgoing voice but could hear people fine. Rezound.... BT headset (plantronics I believe) wouldn't even connect to the phone, replaced with a jawbone. Wife's Inc 4g... needed a new BT headset (had an older jawbone, replaced with a newer one) it would connect to the phone and work most of the time, but sporadically it would have no sound or voice communication at all.
All of these headsets were tested on both the older phones and the newer ones when the issues were occurring. The headsets would work without any issues on the older phones, but the new ones just wouldn't work correctly.
I'm not sure if it was just a bluetooth version incompatibility (they seem to update the BT version with every damn phone) or extremely bad luck, but the problems were occurring and could be duplicated consistently. I know they say BT is backwards compatible, but I've seen issues over the years.

Hmm. I've played around with a few scenarios and I have not been able to find a stuttering issue on my phone. It's always possible that the ROM (UKB) I'm running is responsible for it but I don't think it is.
just to update everyone, i ended up returning the headset. turning off the wifi only temporarily fixed the issue and it came right back up once i got back in my car.. for the original issue i had (ground loop noise over the headphone cable) i ended up getting a ground loop isolator cable - problem solved

Bluetooth Skipping on 23B

Finding this post has finally convinced me to sign up and participate. Long time lurker...
I have the same problem and have been working on hunting this down.
I have a pioneer deh-80ors receiver with the vs985.
On 12b and previous bluetooth works great but everything after that introduces the problem.
The audio plays normally for 15-45 seconds regardless of the app used, then drops for a second, plays for a second in a hurried mess and repeats until the receiver is restarted or bluetooth is disabled on the phone and reconnected.
I have tried a handful of roms for lollipop without success (I do like skydragon though - nice and lean with the termal mod).
If I flash back to OEM 12b using kdz everything works great. If I load an old rom like jasmine 4 it works great. I have tried enabling and disabling all settings from the hidden menu for bt_test with no results other than it occasionally not working at all.
I have read reports of people turning off the call audio from the bluetooth pairing with mixed results, using an app from the manufacturer of the deck (which doesn't work here since pioneer connect was released like two years ago), disabling driving mode (for the S2 and S3), and all kinds of other snake oil. Based on the fact it works fine with the OEM revision up to the one before lollipop leads me to believe it's some problem with lollipop directly. I'm confident it's not the bluetooth drivers or firmware as flashing between major releases resulted in the modem being broken (intermittent LTE) but the same bluetooth issues. That is, unless the BT drivers are built into the release and are specific to each one in which case replacing the new drivers in a more modern ROM with the old ones may work.
The worst part is that most decks don't work with droid devices nearly as well as apple anyway, if we could just plug them in over usb I would be ok with that. Unfortunately the receiver doesn't even see the thing and no manner of apps or settings changes I could do ever got that working either. If anyone has gotten a usb audio connection working (preferably without USB Audio Pro App which is the one that most people like) I would love some input.
