Can we put the 1.5 bluetooth stack into 2.1?

It's like the elephant in the room around here. The bluetooth service on 2.1 is some crazy, broken crap. No matter how many times and how many ways I try to get it to pair to my brand new Kenwood x994 it refuses to save. It will eventually link up BT audio if I search for devices and let the pairing fail, but what a PIA to mess with every time I get in the car. I rolled back to Fresh 1.1 today and I had it paired and working perfectly in 10 seconds.
So here is the question, can we put the 1.5 BT stack into the 2.1 ROM? I already tried the 1.5 libbluetooth.so in the /system/lib filesystem, but it didn't change anything about the pairing problem (obviously I have no idea what I am doing and stabbing blindly at anything bluetooth related).
Anybody have any ideas? Is the BT compiled into the kernel? Can we recompile it with the 1.5 version?

I've asked this question a few times already and the answers are usually 'no'. Gawd I wish we could as no 2.1 roms (I've tried almost all of them) will pair voice (audio is OK) with my Pioneer Avic D3 car radio. 1.5 works perfect

Mine works exactly the opposite. The hands free phone works perfectly, but the phonebook doesn't download and BT audio fails to connect.

It sounds like it may be your phone, your should update with the official 2.1, then take it to a sprint store and have them replace it.
My phone has worked flawlessly to my jeep stereo with any 2.1 rom I have used in the last several months.

So this whole time I thought it was because we had a leaked version, but is this the official ROM that still has this problem. It's not the device cause I've had it replaced twice and my wifes doesn't work either.
I am not able to connect to my Pioneer AVH btw.

I agree, if it was the hardware it wouldnt work with 1.5 either. Besides, Dan Hesse is my boss. He'd get hacked if I took back my phone

Car Bluetooth

Hey guys,
I've got a Kenwood KDC-BT945U car stereo and I'm curious what other people's experiences are using the bluetooth for music. For all of you using a bluetooth receiver in the car, when you play music, does the deck display the Song/Artist/Album/etc.? Mine plays fine. I can pause/play, skip forward/back, etc. The only problem is when it comes to actually displaying the information on the car stereo.
Any similar experiences?
Ps. Besides this problem, the deck is a great complement to the phone. If I can get this problem solved, I can stop using the USB altogether.

I was going to post a similar thread about my issues with the KDC-BT945U. Thanks for staring it. Are you running a custom ROM?
Music for me shows no tag info. My main issue is that foryo is a nightmare when it comes to this deck. Both the deck and the nexus has major pairing issues using froyo. I have not tried 2.1 stock or Cyan's 5.0.7, I assume they work fine. I am no expert, but I think it's the new Radio in froyo causing the problem.
Surprisingly, Paul's desire ROM and this deck work very well for me.
Checking the website, there is a Bluetooth compatibility section. They do not list the nexus. I'm hoping for a firmware update for the deck.
I do have a 30gb iPod in the glove box hooked up via the rear USB and it does display track info on the deck.

Yeah. In my infinite wisdom, I bought a ZuneHD rather than an iPod touch. . . The only Kenwood stereo I could find that was compatible with the Zune was like twice the price. Not exactly doable when I'm 28 days away from being a daddy. lol That said, I'm just using a jump drive for the USB. That's been working flawlessly, tags included. If I can figure out how to get the phone to transmit tag info, then I can drop the need to carry an mp3 player (or have a jump drive hooked up) altogether. I love listening to music from the phone while using the navigation, for the sheer fact that it cuts the music off to make announcements. . .just need to get it working right.
Edit. Btw, I an running eViL's latest FroYo. Noir Tri.

Can you tell me what firmware your deck is running? Mines 3.11
Also can you tell me what Radio you are running? Mines 32.36.00.28U_4.06.00.12_7
Thank you

Same as you. Latest FroYo radio and 3.11 on the deck. Have since wiped and flashed Evil's latest Noir IV (FRF83 based) and still the same results. I have a 16 gig jump drive in there, so I have plenty of music. . . it just kind of sucks for the navigation piece. Phone calls are fine, because they'll interrupt any of the inputs. . . nav doesn't have that luxury. :-\

Thank you for the reply,
I have switch over to Kang-o-rama 0.9 Final (Froyo FRF83). My BT registering is a bit better, but nothing like Paul's R22 desire ROM was. With Paul's ROM, I was able to just keep my phone in my pocket at all times and when I started my car, as long as BT was turned on, my phone and deck synced every time. Now i'm lucky if it syncs at all. I have to constantly re-pair with the phone, and even that is very flaky.
Also, During audio, only 'BT audio' is displayed, no tags.

Did the desire rom display tag info? I have to repair all the time too. . .might be worth switching just for that.

Unfortunately, the desire ROM does not display tag info.

Unfortunately I'm pretty sure that sending the tag info for songs over Bluetooth isn't currently possible. It's a limitation in Bluetooth though, not your head unit.
I have a stock Nexus One and a Kenwood KDC-X994 and after trying unsuccessfully to figure out how to get my song info to show on the head unit I contacted Kenwood about it. They informed me it wasn't currently possible to do this via Bluetooth and that it was Bluetooth that had the limitation, not my head unit.
On a side note, ever since upgrading to Froyo (stock) my phone will only stream music via BT to my head unit with the stock music app, and this is very aggravating. Seems to be an issue with Froyo from seeing other user posts about this topic. I sincerely hope Google fixes this ASAP!

not true, my blackberry storm 2 sends all the song info to my kenwood kdc-bt945u. so the problem is in the phone software not the hu or bluetooth
where are we at on this? im curious as i should have an eris by friday and want to know how compatible it will be with my head unit

Huh. Interesting. I guess Kenwood was wrong, then.

kenwood kind of pisses me off, i dealt with them a lot after i purchased the hd radio unit for the 945u. i was trying to find out why you cannot access the equalizer or any audio settings in hd radio mode (extremely annoying) he said you just cant. i wanted a more detailed explaination and he just made some bs up to get me off the phone. but yeah, just so you guys know, if you get the hd radio for you head unit you wont be able to adjust the terb/bass or anything on the hd radio src. all you get it the direct signal.
but does anyone know if this song info problem has been fixed? in an update or anything?

Bluetooth Issue

So I paired the One with my QED uPlay at home and I'm having issues. The phone has to literally be 30cm away from the receiver or the audio will start getting distorted until it eventually cuts off. I have two uPlays, issue exists on both so its not tbe receiver. Also my iPhone 4s has no issues either. I was hoping the One had better audio than the iPhone since it has aptx, but its quite the opposite. Has anyone tried bluetooth music streaming? Is it just a faulty phone?

Bluetooth and Wi-Fi both use the 2.4GHz channel. Asus had issues with the Prime because of its all-aluminum design where they had to greatly amplify the Wi-Fi signal and use diversity antennas to get through it. HTC uses the latter on the One. When used together, the Wi-Fi signal can overpower and interfere with the BT signal. Try turning off Wi-Fi and see if your connection quality changes. You're the first one to mention a BT issue so it could be unique to your device. Time will tell.

I have had a problem with bt connecting to my car (audi a1) I can hear the call but the other end cannot hear me. Going to delete connection and try again tomorrow.

Thanks for the replies. I switched off WIFI, re-paired the device and bluetooth started working perfectly, so it makes sense it was interference. Strange thing is I turned WIFI back on and bluetooth was still working fine. I'll do further tests in my car tomorrow see how it goes. If I'm not convinced I'll just get the phone replaced.

I have also had issues with bluetooth paired to my hands free car kit. Issues have surfaced when streaming music and also when making audio calls via bluetooth.

The One X had a similar issue:
http://forum.xda-developers.com/showthread.php?t=1688538
It could be that when I was first trying the WIFI antenna was stuck on high power, which caused the interference, but when I reset the WIFI it reduced its power and no longer interfered with the BT. I have changed the WIFI at home to run at 5 GHZ, but work still runs on 2.4.

Apparently 1.29.709.4 has been officially released in Taiwan by HTC, so it shouldn't be long before the update arrives to the rest of us (hopefully).

got the same issue...some times I got no lags in audio streaming, but sometimes they are there...until it (maybe) will be fixed I'm using a widget, my cousin has coded for me yesterday . Quite simple solution. If I press the button, wifi turns off and bt turns on...works fine for me, so far

Bluetooth Audio Stutter / Skips

I have received my T-Mobile Note 4, and I have the infuriating problem of random Bluetooth streaming skips / stutters. Does anyone else have this issue? I know it was a known problem on the S5's, and it never really got fixed...
Does anyone have any solutions for this? I checked out the ViPER EQ mod, could that help?
Currently I am 100% stock (latest version, got the T-Mobile patch right away), and I only use Spotify for music. I have experienced stutter in my Nissan, a pair of Sennheisers, and a Monoprice Bluetooth adapter. What's also upsetting is that the stock Samsung music player often starts playing when a Bluetooth streaming device is connected...
Any advice?

not sure if i ever saw a way to fix this issue.

It's funny because I'm coming from the M8 and it was flawless for me. That is was running 4.4.2, whereas this is 4.4.4... Any correlation?

I really don't know if this an issue. My M8 4.4.3 and had same thing. But to be fair Note 4 is more superior inside my car. I am able to listen to my text msg. Voice commands works really good on note 4.

I have this issue from time to time on my Nexus 5. I have to reboot it to fix it. It happens maybe 1 out of 30 times I use BT headsets. Enough to be annoying but not a deal breaker. I am beginning to think this may be an Android issue and not Samsung. Those that have the issue on Note 4, does a reboot fix the problem?

Every now and then when I play Tunein Radio Pro, it would be a hick up. I already did the 30 sec buffer. But usually it works. Is this what you mean?

In my Jeep Wrangler I have BlueTooth. Every few months when I get a new device, I always have to call my mom for the BlueTooth test. The Note 4 has been the only phone to pass. For whatever reason my mom's phone would always sound like I was in a tunnel with the exception on the Note 4. Even the LG G3 failed this. In my 2012 GTI I had issues with some devices as well as my 08 WRX. It always came down the the BlueTooth stack for phone call quality and skipping and sometimes just dropping/crashing out of BT all together. Hope you guys get yours resolved. I know this is a huge problem. Heck when Note had its recent update, I was worried it would break something its just been too good so far! Best of luck guys.

I believe its a kitkat bug. It happened on my note 3 as well

Might warrant a return.
This is so annoying. I'm coming from an M8 (and previously M7) and use bluetooth for everything. Wireless headphones at the gym, wireless speakers at home, media in my car, and a Moto360.
Never had any skips/stutters on previous devices through any of these. Moreover, sometimes the music just STOPS and drops the connection and I have to repair the two devices in the middle of a workout. Is anyone experiencing the music STOPPING? Might return/exchange mine if not.
This happens through any media app - GPM, Milk, Netflix, etc. Want to throw my device.

I am having this issue in my Outback, but it is not happening in my WRX. I was thinking maybe it just doesn't like one, but now I see this is a larger issue. I haven't had this problem with my S5, so maybe it'll clear up when some Roms are released.

I'm having the same issue with my wireless Bluetooth headphones. I thought it was because I was too far away from the phone, but I'm having the same problem when I'm close to the phone also. My Note 3 does not have this problem.

I used my like at least 6 years old Bluetooth headset for like the 4 hours and in that time I barely had skips it only skipped when I left the room and went a few feet away also
Sent from my SM-T210R using XDA Free mobile app

same here
I'm having the same problem

I find this happens when the screen is off. When it's on, no issue. I hope an update fixes this soon.

This stopped after I went to Firekat Rom. Not sure why or how, but Bluetooth is smooth now

Just wanted to verify if anyone is NOT experiencing this issue? If there are Note's out there that are not experiencing it then I might exchange mine. If this is a software issue for all notes then this blows.

As I reported before, I had a similar issue on my Nexus 5 and rebooting would fix it. It was a rare occurrence but it would happen from time to time.
I have not experienced the issue at all on my Note 4 in the 8 days I have had it. I use BT quite a bit with my Heart Rate sensor and BT headsets while running and also connected to my stereo in my Sonata. Has been flawless so far.

This might have something to do with S-Health. Audio skipped for me every 10 minutes or so. Didn't matter the BT equipment. Yesterday, I decided to Disable S_Health. Today, at the gym, about a 90 minute session...no skips. The guy above using FireKat, by any chance that rom has S-Health disabled/uninstalled by default?

Bluetooth Issues...

I use BT at home daily for listening to music and netcasts. I have a couple of different BT speakers as well as the awesome Panasonic Link-to-Cell phone system for those who have dropped their home hard-wired phone lines. I also use BT constantly when I am in my car.
With my LG G2, BT connection was seamless and immediate, all the time, for years now. It connected to multiple devices as soon as I walked in the door and with my car audio as soon as I started my car.
With the N5, it always needs to be re-paired manually - especially at home where there are two devices waiting to pair with it as soon as I come home. It'll pair with the Panasonic phone, but when I select a speaker, the N5 disconnects from the Panasonic and then I have to re-pair with it. It will work once I spend a moment managing connections. In the car it often pares immediately, but sometimes not.
Another observation is that the N5's BT range is short, and it will drop if a line-of-sight gets interrupted momentarily.
In an attempt to fix, I have wiped the cache for both Bluetooth apps that come with the VZW N5 - that didn't help. Then, I wiped the system cache, also no dice. I wonder if this is carrier-dependent (I am on VZW) or something to do with older BT devices and the newer BT protocol that the N5 uses. I've read that the N4 has similar BT issues.
Overall, it's usable, but not as good as my old G2. Anyone else have these issues? Fixes??

This issue persists to this day. I can accommodate it with some manual intervention when I want to connect to my BT speakers.
Looking to get a BT 4.x speaker to see if it's just a BT version issue.

I only use Bluetooth in my car and I haven't had any issues whatsoever. Always connects as soon as I start the car and never drops the connection or anything. It syncs my contacts and everything just fine as well. I don't use Smart Lock however. Maybe try turning that off?

I think that's the case. For some reason samsung's 4.1 Bluetooth protocol is not backwards compatible. Ever since the s4 Bluetooth meta data has stopped working in my 2012 Mazda. Works fine with my N5 (nexus 5) and my LG G4. If I had to bet I think that's the issue with you. I could be wrong. Just thought I'd share.

Note 5 always works with my car, does not drop or anything but it has an unstable connection to my samsung gear circle headphones. I believe it is the 5.1.1 update, because they work with my wife's note 3 just fine and they used to work fine before the 5.1.1 update.

Did you ever resolve your issue? looks like some are successful after getting their device replaced and others are not and say the problem comes back. All seems to be related to the 5.1.1 update..

Bluetooth and Note 5, horrible combination

Thanks for writing. I found out that if I disable wifi, it connects a little better, though not as good as my wife's phone, Note 3 (my previous phone)
I tried to find ways to change the frequency it connects, but google was not helpful. Maybe some of the experts here could be helpful, I do not know.
Anyways, I tried to connect to our smart bulb yesterday. It would pair, but would never connect, wifi or not. On the other hand, the Note 3 connected to it immediately.
They keep updating the gear circle software but it is the phone fault, since gear circle is able to connect to my laptop from even another floor!

It's not the BT device... I have terrible luck with expensive purchases and my note 5 was no exception. I upgraded from a galaxy S relay (love keyboards) and about 1 month later my Bluetooth stopped working from all through my house to needing a DIRECT line of sight and max range of about 2 feet. Netflix, hulu, audible all pretty much useless with this issue.
I returned it and got a new one (not referbished) and I noticed a slight lag in key strokes. About 2 weeks go by and the bottom half of my screen is going haywire. Trying to scroll a Web page and it would click everywhere. Typing like I am now would result in 100s of extra letters I was never close to pressing. I returned it and got a referbished one and same thing... my 4th one which I'm using to type this just started doing the Bluetooth thing and I'm so mad.
It's not the Bluetooth device because I tried my old Plantronics I used for 5 years, my new Plantronics, my car, and these weird speakers that have water pumps in them and the issue was the same. I love this phone but it seems to hate me...

Quick question, do you have android 5.1.1 or 6? I still have 5.1.1 and thats when it started with the problems. It was all fine and dandy with android 5.0.
My wife has a Note 3 with 5.0 and the same headphones are just fine with it.
I have been waiting for android 6 to see if it works out.

My Note 5 upgraded itself to Android 6.0 and all my bluetooth problems are solved magically. I cannot believe how they can manage to screw up things for so many months and we have to wait for the new OS to have it solved. For Samsung Gear Circle none the less. I know I am not buying bluetooth watches or anything in case they screw up bluetooth again in an "update".
