So, I have searched all over these forums, and cannot find a difinitive answer or solution. I have problems with A2DP when connecting w/ the BT in my car, since installing a 2.1 ROM (currently DC 2.09.01). When connected, the music plays about twice as fast as it should, then slows down, then speeds up again. Conversley, Android 1.5 worked fine. There has been a lot of talk of BT issues, but it doesn't appear there are any solutions. Am I correct, or has someone found a solution? THanks.
ZenEXP works if you dont mind switching.
I have had those problems occasionally with all 2.1 ROMs I have tried. Usually, if I pause and then unpause it solves the problem. Sometimes I have to do it more than once.
I'm currently running ZenEXP and I've had the problem a few times, but it has been significantly less than with other ROMs. However, AVRCP hasn't been working with ZenEXP, whereas it has worked on other 2.1 ROMs, such as DC.
So, with the unrooted stock Sprint 2.1 software, A2DP works?
The Darchdroid ROM actually fixes this problem! I had the exact same problem as you with playing audio in my 2010 Mazda 3 and Darchstar's ROM fixed it for me, it's the only ROM I have found so far that fixes the bluetooth
I have a problem with my bluetooth headset when I'm playing music, the music stutters alot, I almost have to hold my phone a certain way with very little movement in order for it to play decently. Any solutions on that problem?

Turn off/disconnect headset while playing music fixes studdering for me in settings under bluetooth for the connected device. Disconnect the ' phone' while playing. Haven't really tested this on anything but my kenwood head unit.

here's a reply I received from HTC support:
Hello, I understand that you have had issues with your bluetooth since the update for your Hero. With the update, the entire bluetooth stack was updated, and thus some bluetooth devices that previously worked are unfortunately no longer compatible. While we have not heard any information about nor made announcements about any upcoming patches to address this, it is not at all out of the realm of possibility. Otherwise, you may want to try a different bluetooth headset. I do apologize for any inconvenience you may have experienced. If you have any other questions, feel free to contact us again. You can find additional support at support forums at community.htc.com. There is also a customer satisfaction survey for you to take if you are interested.

Bluetooth Stack?
So is it possible for one of the developers on this site to rewrite the bluetooth stack or copy the old one from 1.5 that worked?
I have a Panasonic TH12 bluetooth home phone that worked fine before 2.1. I recently bought an AT&T bluetooth phone and it does the same thing. Will pair but not connect.

I have to call BS on this. (Not on the post, on the reply)
Why would any company not support legacy hardware as simple as Bluetooth. Especially since most devices aren't even Bluetooth v3/v4 standard yet. And Bluetooth 2.1 is 1. Not very old and 2. What 90% of Bluetooth device still manufactured are! and its been around since 2006!
I honestly can't believe a company is going to just say "Oh its to old" instead of fixing their crap. as far as I know v3/v4 is fully backwards compatible to 2.1 because they include "Classic Bluetooth" protocols!
Not to mention I doubt the hardware in our phone is even capable of v4 stuff. I'll have to do some more research on what BT chip is in the phone. Utter BS.
Either Phillip or HTC is a moron.
CDMA Hero Specs for BT:
Supported Profiles: HSP 1.1, HFP 1.5, A2DP, AVRC, (OPP, PBA)
version 2.0+EDR / possibly upgradeable to 2.1+EDR, plus OPP and PBA profiles
2.1 FULLY backwards compatible to v1. Meaning HTC built the crappiest BT Stack allowable by law to say it includes it. May as well have not bothered.
Someone could probably redo things with AOSP and a newer bluez stack.

Yeah, I just bought a BT USB adapter so I could exchange files and synch and stuff. I got it to work ONE time and all it did was pass 200 of my contacts to my phone from my PC. Like it was just waiting to upchuck on me. After that, nothing.
There's three hours of my life and $8.99 I'll never get back.
Bluetooth is pretty much the #1 complaint that users have been posting on the Sprint Community Forums (here's the HTC Hero section). Nearly all of those complaints say that Bluetooth now doesn't work at all or just plain sucks on the stock 2.1 Sprint/HTC release. Which probably also means that any ROM here based on 2.1 stock will also suck it up bad with Bluetooth compatibility. Known problem, no one has done anything about it yet. It sounds like AOSP ROMs don't have this issue, so at least that's good.
All,
Does anybody have any fixes regarding the sound quality when using Bluetooth A2DP protocol? I use my Evo to mate with a Bluetooth receiver so I can listen to Rhapsody over my home stereo. The sound quality is flat. The high frequencies are not present. It sounds like a bad quality MP3. I know that its the A2DP causing the quality issue as directly connection (through 3.5 jack) is awsome.
The Apple 3GS A2DP sound quality was awsome. I am not sure why the Evo is not sounding good. Any help would be most appreciated.
Thanks,
Lance
use the cyanogen rom--this uses a bitpool of 53 giving you the best bluetooth quality possible. the stock/sprint/htc bluetooth drivers are set for a bitpool of 32
Is there any other ROM that has the bit pool set to 53?
Lance
Nope all Sense roms use HTC's ****ty low bitpool setting. This is why I'm running CM as well it's the only rom I can A2DP to my Sony Head unit and get good audio. I attempted to contact HTC about this issue here's the juicy details
Here's my initial question
I have terrible static when streaming music over A2DP on my HTC EVO to my sony mex-bt2800 car radio. If I use CyanogenMod 6.0 which uses a open source bluetooth stack my A2DP is crystal clear to my radio. I have used logcat to look at whats going on I dont know if its a bitrate problem or a bitpool problem or if my radio isn't in your acoustic database.

Here's the response I received
Although the android software has been updated to be more compatible with Bluetooth headsets and car kits. Most of the time a Bluetooth manufacturer will have a list on there website stating devices they have found compatible, but this is not always the case. From the information on your issue it seems that your device is simply not fully compatible. The only thing we would be able to recommend would be to try another headset.
Then my response back
I would like an Engineer to read my question if possible since I don't think you fully grasp what I'm saying here. First My EVO's Bluetooth A2DP WORKS 100% clearly when using a Open Source ROM which implements Bluez Bluetooth stack http://www.bluez.org/
When I run your Sense UI ROM the Stock ROM you release which uses your own proprietary Bluetooth Stack I get static in the background so you cant really say its my phone now can you? Its your implementation that's not working properly. I'm not about to try every car stereo till I find one that works with the EVO when I know my stereo can work perfectly with my phone when using a properly coded open source Bluetooth stack.
Here is some extra info from a logcat that shows how your Bluetooth makes a connection through A2DP and what I believe is too low of a bitrate or bitpool setting
http://forum.xda-developers.com/showthread.php?t=708265&highlight=bluetooth+bitrate
PLEASE DON'T GIVE ME A ANSWER THAT YOU JUST READ FROM A SCRIPT. I would like a true response from someone who understands and can grasp my question fully like an engineer or a developer, when you give me a generic response of oh your Bluetooth headset isn't compatible keep buying new ones till you find one that works, that really makes me upset since you didn't even read my question it's a car stereo and there not cheap.
I await your educated answer.
And there final bull**** reply
We apologies for any inconvenience you may be experiencing. We will document your concern for review in development of our upcoming devices and future software updates.

Well I commend you for trying. This is something that makes me want to tear my hair out so I would love to see this resolved as well.
good on ya mate.
anyone know how to get another bluetooth stack on stock rooted 2.2?
I asked Flipz a while ago but I don't think he's looking into it. I also asked Netarchy he said he would look into it sometime but that i shouldn't hold my breath since he hadn't even looked at the code yet. HTC has released the source for their Bluez implementation so all we need is a dev willing to look into adjusting the bitpool setting.
This is a HUGE problem. I am flashing CM6 right now. HTC I am very disappointed with you..
The cyanogen rom also has great dsp equalizer
CyanogenMod will also make you a tropical island than transform your EVO into a jet plane and take you there ;-)
But in all seriousness, yeah, CM6 has BT fixed. One of my friends nagged Cyanogen about it last month, and he patched it right away.
I wish somebody could help us by increasing the bitpool on the Bluetooth driver. The Evo would be so much more enjoyable (for me at least) if the sound quality was better thru A2DP.

It would be nice if there can be a patch of some sort...
Just an update today I got a call from HTC customer service since i gave a poor review of my experience on a survey they sent me. Talked in great detail about our problem with the Bluetooth stack told him about the bitpool setting how its 53 on CM and 35 on there roms. So hopefully on the next update well get a fix for the Stock Sense UI rom.
^^LMAO!!! dont blv the hype
I read that the CM6 ROM has this issue fixed. I have also read reports that the ROM email client doesn't support word wrapping (which I really do need). Can anybody confirm this?
Also,
Can anybody in ROM land please create a patch or an update to their ROM which increases the Bitpool to 53? I understand that the Bluetooth driver code has been released.
Thanks

That was a streaming issue, not a bitpool issue.
The BT audio was a lot better on my TP2 when I updated the registry bitpool to 48 from 32.
I wish they would fix it.
I was wondering, if anyone has spotted a build/kernel/... with FM radio working?
Especially with finally getting stutter-free sound, a working FM radio app is (for me at least) the only important feature missing from our Blackstone Android builds!
(for example, currently running XDANDROID 2.2.1 AOSP FRX04, no FM radio app to be found...)
I searched a lot, have tried ~10 different builds from XDA and Neopeek over the last month, but no result.
If anyone can point me to what I'm missing, I'd be grateful...
Cheers,
Robbert

XDANDROID 2.2.1 AOSP FRX04 on blackstone (690 MHz), viruscrazy test kernel for audiostuttering fix and camera (3Mpix) test.
There are very few Android phones with built-in FM reciver and AFAIK they all have FM Radio App that is device specific. I don't know if it's even possible to port something like that.

I was just hoping that it would be possible, since over at the Leo threads, all build/roms seem to have FM radio working, but maybe their app was ported from android device with similar FM chipset?
Our radio seems to be BRF6350 Chipset, other devices with the same chipset:
BRF6350 Chipset:
HTC Diamond, HTC Raphael (not CDMA), HTC Polaris, HTC Topaz, SE Xperia X1
(hero, touch pro, tattoo are also found when googling BRF6350)
Could be interesting to look into?

Yeah, was also my first thought, but so far I could not find SD builds/Roms which included radio in any of the threads for those devices, basically Android development for the Leo appears to be in a class of it's own...
On a side note, it seems everyone just streams internet radio, and does not mind lacking FM radio...
Since I currently do not have a data package (always within reach of WIFI at home or at work), I kind of wanted radio for the short trip to work on my bike where WIFI coverage appears to be lacking
(also, in the end, FM traffic information would be nice to have in "offline" route navigation, as I have it now on WM)
I'll look further and report back if I find something of interest, maybe I'll politely bother the guys at the Leo thread
Cheers,
Robbert
I'm in the same situation XD Also I thought of TMC too, IGo8 in WM with it is great.
I'll see if I can find something

Not the same chip though, but I'll have to start with something. BTW, it seems that it needs to be installed via ADB or els it doesn't work. I'll do some tests today.
Edit: 2 problems: Seems they are for Sense UI and need kernel FM support. Hm...
I'm not getting anywhere. Radio FM is supported via Bluetooth chipset.
I'm investigating the htc fm code...
FM radio needs kernel AND android framework support. So you will need: kernel driver, system support for this driver and FM App that uses both. Probably that's why nobody touched this yet. Too many changes since FM radio is not officially supported by google and every manufacturer does FM radio his own way. I'm not saying it's impossible - just not easy.
I've dl'd Cyanogen mod FM app source, let's see what I can do.
Dear friends,
I had read in some threads about the existence of the BCM4329 inside the HD2, that it makes FM receiver AND TRANSMITTER options possible.
So, I was wondering about the chance of having FM transmissions possible, if things had progressed with the years (those news are from 2010, still focused on WM6.5), also thanks to the existence of very updated versions of Android, although it seems to me that nowadays an FM API is still not available to us.
Thank you.
What are you talking about? Where did you search for this? As a Google search you are Fired!
Just instal Spirit FM and you are ready to use FM Radio on your magnificent HD2. Plug the Headphones which are needed as antenna. Also the Radio will turn on Bluetooth because the chip to run FM radio is implemented into it.
Have Fun.

Unfortunately, there hasn't been much progress on that field (as a matter of fact, there hasn't been any progress at all). If you read the replies in that thread, they couldn't make it work. The furthest the could get is to confirm that the HD2 indeed does have the chip.

He isn't talking about the radio receiver, he's talking about a radio transmitter. E.g. You run a special app, ask the app to transmit a song using radio. And then you can listen to that song, say, in a car using the radio. No wires/bluetooth connection needed. Simply tune in and listen. I really wished they did it.. what a pity.

Yeah, I figure out this at the end, my bad. :angel:
It will be a good option but the radio receiver will have to tune to a specific frequency and this part I think will be the issue here. In terms of words so simply but unconventional.
I think they don't do that for a national security.
If you use the Sony stock FM Radio, as good as it is, Sony missed a setting when porting their Radio3.apk from the Z/ZL Qualcomm FM chip and driver to the Z2's Broadcom chip and driver.
If you live in an area with moderate signals, you will notice that although the stereo image is very wide, it doesn't get narrowed by the Broadcom chip or API as the signal strength varies. This results in a noticeable increase in background noise (hiss). Sony forgot to enable Stereo Blend....
The link below allows you to use an FM Radio app that correctly blends the stereo image automatically,
I use FM Radio a lot - this is a vast improvement.
Once you have installed the app, it will run correctly at default. If you are rooted DENY SU permission.
Note that there are some UX bugs to work out at the moment...but it works well. This is only a test release.

Remember to support dedicated developers like Mike if you like their work. Spirit FM is available via G Play. If you like the test release, buy the app.
Thanks for the post. Audio sounds great from this app. I have a weird bug with my phone though and the FM Radio. In both this app and the built in FM app, it will only play audio (through headset or speakerphone) when the screen is off. Is it supposed to be this way? Anybody else have this or know why it might be doing this? Updated to latest .314 update in Canada on an unlocked Z2.

Thanks! Also found this after re-googling it today. Somebody also posted this solution on the Xperia Support forums. Guess it's the always listening "OK Google" that was messing with the FM Radio. Strange but at least I know what the issue is now! Wonder if this will be fixed with future updates to either the Google Search app or the FM Radio app?
