Nexus One Bluetooth issues (short version: it sucks)

Moved from a MT3G to the Nexus One, and I've been very disappointed by the Bluetooth.
The phone pairs fine with my Bluetooth devices, but it rarely transfers the audio. I've tested it on several devices:
Chrysler MyGig: pairs, but doesn't transfer audio. Carkit DOES show incoming and outgoing calls, but audio stays on the phone. Pressing "Bluetooth" in call doesn't do anything.
Garmin Nuvi 855T - pairs and calls work, but it regularly pops up with "phone connection error"
Spracht Bluetooth carkit - pairs, but same audio transfer issues as on the MyGig unit.
These three products worked perfectly with the MT3G, so I'm curious what Google broke and whether any of the other non-stock roms out there can make Bluetooth work correctly.

having issues myself with streaming A2DP in a 2010 VW. Phone works great but music clips almost like it's buffering. Issue doesn't exist with other phones.

My issue with bluetooth is I cant send files to my laptop anything works fine...

Don't know about your issue, but my N1 hasn't had any major BT problems. Occasionally it drops out while running with my Plantronics with A2DP, but that happened with my G1 too. File transfers are no problem for me either, and I never get disconnect problems. Stock rom was fine too with BT before I installed CM5. Maybe you have some app that's interfering with it? Try killing everything.

I have an aftermarket parrot bluetooth car kit and its worked perfectly with every phone ive ever had: sidekick 3, tmobile dash, bb curve, g1, bb 8900, mytouch. and now with the nexus it says it pairs but wont connect. so its completely useless. and i live in california so i have to have handsfree. bummer.

What annoys me most is a) how this wasn't picked up during testing by Google and b) how they managed to break something that worked perfectly on the G1 and MT3G.
It has been submitted as a bug in Google Code, but that doesn't mean they'll fix it. Sad that I have to use an iPhone just to make calls in my car when I paid $563 for the N1

my jawbone prime works great..
sometimes i have to send a file twice to my mac, but it does send, and i can send from mac back to the phone

Really? My first, and ongoing, impression of the N1's blue tooth is that it's really slick.
It pairs with my in dash NAV on my '09 Jetta TDI before I pull out of the driveway, every time. Phone calls always work and the A2DP streaming is flawless, this is the first device I've seen it actually work and play well with -- consistently .
The sound quality is BETTER than my iphone through the apple A/V cable; with the iphone I had to put an audio filter inline behind the dash to suppress engine noise caused by a ground loop. I'm considering removing it now since blue tooth A2DP streaming would obviously be immune to this problem.
I couldn't be happier, personally. I can control playlists from the stereo head unit or the steering wheel while the N1 is in my pocket. It's been very reliable and has performed beyond my expectations... not to mention the "wow factor" when somebody realizes where the tunes in the car are coming from.
For me, the blue tooth performance has been an unexpected bonus... It wasn't a consideration when purchasing the phone but now I feel it's become a "must have" feature.

- Honda Car Kit
- Philips SHB7100
- Gear4 BlackBox
- two Desktop Docks
are working fine.
"Audio Link" sometimes has "clipping".

Pairs fine with my Garmin Nuvi 265WT, however ALWAYS drops a call around the 5 min mark. My G1 did the same thing with my Garmin Nuvi 680.

My N1 won't work with my 08 Nissan Xterra. Pairs just fine but won't transfer audio. This worked fine with my Samsung Blast, G1 and Cliq.
There is a thread about this on the google nexus one help forum but unfortunately I'm not allowed to post external links. I'd recommend voicing your problem over there to let google know this is a widespread issue.

I have problems with my BMW Bluetooth car kit. It connects, phonebook transfers, try and make a phone call and I get no sound. Receivers phone rings but no sound in the car. Once the phone call is cut the Bluetooth disconnect and won't connect until the car Bluetooth is turn off and on.
The Bluetooth on my old iPhone worked perfect every time. I thought Bluetooth had standards and should work with any device if it supports the profile.
How hard is it, especially for a company like Google to get it to work.

My Lexus bluetooth pairs perfectly every time, and usually the call will last a couple minutes before I suddenly get no audio going to the car, or the car may say "check handset". At that point, I have to click the Bluetooth button on the phone to switch to the handset. If I restart the phone it usually works fine for a while, then this happens again. I never had a problem with 3 other phones in this car.

I've got a BMW with a bluetooth kit and have similar issues.
The way I've overcome it is to always keep the bluetooth in the car "on" and on the Nexus "off".
When I get in my car with the key fob in the ignition, enable the nexus one bluetooth and it works.
It's a pain to enable/disable the bluetooth on the handset but it works until there's a proper fix for it.
Also i recently got Modaco's Desire Rom on the handset and found the above procedure works without fail.
One other thing I noticed since having the Modaco Desire ROM is that when you're in a bluetooth call all phone audio comes from the car speakers.
Never used to happen with the stock nexus rom or my previous Touch HD.
It's cool but would be great if there was a way to enable the bluetooth audio so phone sounds came through the car speakers without making a call.

I have a very similar issues with my Nexus One and my Lexus IS350. It pairs OK. But if I make a call, the cars display flashes "check handset" and then puts the call through. I can hear the other end, but they can't hear me.
This is a "deal breaker". Guess I'll be sending my Nexus One back for a refund.

I have been unable to use bluetooth to transfer files OR to tether.
I paired it with my MotoRokr speakerphone, and it paired fine, but I didn't use it to see if it actually works.
Regardless, there are obvious issues with the BT that need straightened out.

how did you that?? i have a 2009 vw

My Nexus one will pair with my computer, but it won't send or receive a file. It won't even go to the trouble of discovering my jawbone earpiece. I'm really disappointed since this should be the simplest of tasks that such a wonderful phone should accomplish. I thought it was just my phone, but seeing this thread makes me sad that that nothing has been done and hopeful that it's more than just my phone and, therefore, there's the possibility it will be addressed in one form or another.

Ok, I played around some more tonight with bluetooth.
It works with my Motorokr speakerphone great. I can talk, make calls, etc... works well.
I got the bluetooth tether working too.
I still have not been able to get file transfers working though. They look like they send, the phone thinks it sent successfully, but the computer says the transfer was interrupted. I'm not as concerned about the file transfer as I was about getting the tether working.

paired the nexus one to my '09 Nissan GTR ... works perfectly fine ... everything works as it should, calls come in perfectly each and everytime ... i do however, leave my BT running 24/7 on both the car and phone

Bluetooth Streaming Audio from Pandora to Car skipping

unfortunately when i connect bluetooth to my car radio the music skips about every 15 sec. very annoying. Anyone else having the problem.
I have an iphone 3gs that doesnt skip and works great. I love the Evo but bugs are continually showing up.

Its your internet. Try updating your prl.

i did update the prl before i tried it.
still does it.

I have a bluetooth reciever for my AVR and I noticed some skipping as well. Not as frequent as you are saying but if I moved more than 10' away it would be rather bad. The Bluetooth range seems to be poor. In a car I can't imagine you having a problem. I have heard of some issues with factory bluetooth.

I had same problem till I decided to turn off my wifi.. and it started working fine.. it just doesn't have to do with Pandora, its will any Music that you stream over Bluetooth..
Just turn off your wifi and it will work fine.
Thanks

Or just place your phone somewhere else in your car. Bluetooth has very lousy range (isn't it like 10 feet in perfect conditions?), and as such moving it a foot or two somewhere else could make a world of difference.

Its definitely not the internet. I could be at home in wifi with phenominal internet it even laying it off of my SD card. If im in a vehicle or on a bus, its pretty solid and works really well. I walk out the bus and walk around either to m next bus or to work and it fails to play for more than 4 seconds without skipping. And its not like a short, nuisance of a skip. It often stays skipped for up to 3 seconds at a time. Completely unusable. Happens however i connect my phone to any a2dp device. Tried tweaking the /etc/Bluetooth/audio.conference file as suggested in a couple nexus one/s sites, but unfortunately seems to be specific to those phones. This is making me hate this phone. Every other phone I've had in the past two years does this just fine. Whyis it having such a hard time with such a simple task that others have done perfectly? Even other Roms work better but i like also better than sense anyday. Maybe its a kernel issue?. I really want this fixed. But it seems like no one is even trying to work towards a solution. Not on the surface anyway.

Did you try turning off your wifi and any other unneeded services? The only time I have had skipping over bluetooth is when I have my wifi on as well, other than that it streams smoothly through my car stero and computer over bluetooth.

This.
If that doesn't help, then if possible, you should use an aux in cable to prove it's only a bluetooth issue. If it still skips, I'd try a new rom and/or kernel. A2DP performance seems much improved in CM7 compared to Sense roms.. or at least it seems better to me.

I've had the same skipping problem with my bluetooth earphones and evo. The only slight solution that I've had was holding the phone in direct line of site with the bluetooth earphones. When I do that, it doesn't skip as much.

Streaming bluetooth audio to car stereo
Thanks Anku13, your fix works. Just installed a Clarion CZ501 bluetooth receiver in my car, experienced skipping audio every 15 - 30 seconds once my Leo connected/streaming. Killing WiFi was the trick. Love not having an AUX cable lying around in the cabin.

Problem with AUX

Hi,
i have Galaxy S with I9000XWJM5 and have some strange problem when listening to music in my car. I connect phone with AUX cable to my car radio.
The problem is that playback have glitches every few seconds, it's 4-6 glitches per minute of playback. I don't know how to exactly explain that glitch. It looks like you quickly disconnect/connect jack to phone. I've had iPhone, Samsung Wave and several other mp3 players connected that way in my car and none of them had these kind of problems. I've also checked jack and cable and everything is fine. Connection to phone is also fine during testing. Do you think it's because software? Or maybe it's bad checking for AUX signal in the phone?

I'd say most likely software, but I'd be guessing.. There isn't really any way of knowing.. Is this with FLAC?

I'll try change something in my car audio. I think it might be caused by changes of inpedancy.

I don't get glitches in my car AUX unless the files themselves glitch and stutter (which they do with FLAC files). I would check to see if you have any EQ settings in your car stereo on, that is the culprit sometimes.
How is your playback with headphones/earphones? If you don't have same problems with them then it's likely something with the mini cable or the car stereo. If not, then likely something with the phone hardware/software.

Playback with headphones is 100% good (sometimes excluding FLAC playback as you said). I'll try changing EQ in car and if this don't help i'll try changing inpedance and write here what happened.

have you considered using bluetooth in car to stream audio from the phone instead of AUX cable?

I was thinking about it but my car radio don't have bluetooth and I won't change it because it's pretty high end Blaupunkt and I love how it sounds.
Second thing is that a2dp has lower quality that regular aux.
Sent from my GT-I9000 using XDA App

I would also make sure it's not the data/phone connection somehow getting in the way of music playback. Try it on the airplane mode and see if you are getting the same glitches.

i think i know what you mean.
you are refering to those annoying sounds when a call is about to coming, or when a data transfer is in progress, or whenever your phone switches from one tower to another tower
you get the ddddddd...d.d.d.d.dd..ddd.d.d.d.d.d.d.dddd... sound on the speakers, if your phone is connected to the stereo via 3.5
that's one of the reason why i switched to BT in the car.

I've checked line out with amplifier in my house and it's working 100% fine. So i have to check AUX in my car.

Bluetooth Audio Quality

I paired up my new Focus with my 2010 Acura TL yesterday. As I was driving home from work and talking, the volume from the car's speakers ranged from high to low and eventually dropped the call. I thought it could signal strength related but I had 5 bars so I tried again. This time the call didn't drop but the audio was horrible. Since yesterday I've tried to make calls in several areas of town and the call quality is just not very clear. If I talk and listen normally through the handset, the call quality is good. I have an HD2 that doesn't have this issue so I am wondering if this is Windows 7 related...

i have a bmw and have experienced similar results at times. though i think my iphone did have its own set of problems sometimes also. i have noticed the increase/decrease in volume before, though. it would be nice to know the source of the problem. likely the phone, not the OS i would think. my phone has never disconnected yet.
i don't make a lot of calls in my bmw really, but i'm getting addicted to the WP7 so i don't really feel like i will be able to trade in and go back to the iphone at this point if the problem is with the focus and not just needing a software update. though it would be nice to have an answer.

I am also disappointed in the quality of the Bluetooth connection between my Focus and my Acura TL (2009). I had the Focus with the same car, and no problems with the Bluetooth connection. With the Focus, the sound quality is terrible, and I often lose the connection between the Focus and the car. Not a dropped call, this can happen with 5 bars, its the bluetooth connection that drops.
Has anyone been able to improve their bluetooth connection?

The bluetooth in my 2008 Altima is useless with the Focus. It's all garbled up and just unusable. My original AT&T Tilt was the same way. I think it has something to do with the Bluetooth stacks used in these phones. Sadly, Nissan isn't planning on updating the firmware in their handsfree kit for my car, so I just got a good Blueant headset. Not the ideal solution, but it's better than nothing since I drive a stick!

I use mine with a clarion deck. Works and sounds flawless.

I have an aftermarket Sony deck in my car.. Bluetooth call quality is generally good but when it comes to audio streaming..it's hit or miss. I'd say 50% of the time there is always a loud 'hissing' sound in the background which makes the music sound like I was playing it off an old cassette. Other times the music is absolutely crystal clear without any hissing or background noise what so ever..as if I was playing it off a USB drive or CD. I use Slacker to stream music or songs stored on the phone through Zune.. same thing. At times I have to reestablish the Bluetooth connection several times before the hissing disappears.

I use my focus with a Sony BT Stereo and works fine. And all the in/out calls works flawless. Maybe is the BT profile (if the stereo don't have AD2P profile, the phone works in mono instead stereo).

I have the same problem with the sound volume going up and down. 2006 Range Rover. I finally gave up on using bluetooth in the car. My orevious HTC Focus and my wifes iPhone both work fine in the car

I have the Sony MW600 Stereo BT headset and a 2010 Mazda 3, both work flawlessly

Really, really poor bluetooth audio quality?

On my G6, I have really terrible audio quality over Bluetooth connections, I've had two separate G6s, of different colors, received weeks apart, and they both suck for Bluetooth audio, especially my Sony car stereo, and LG Tone Free... can anybody else report on their experience? Does your LS993 sound awful on your Bluetooth devices?

Have a fairly new G6 bluetooth og Bose earpiece working very well, also on 2010 F150 pick up and 2012 Buick no audio issues. Audio has been fine so far.

Mine also is pretty poor. The volume level is about half the level of the satellite radio or fm stations in my car

Hello all.
I had G2 in the past and I use to listen music in my car, using Bluetooth connection to Pioneer head unit. I have Spotify premium account and I have my Playlist downloaded with the best quality. However once I got G6 a week ago I noticed that audio quality from the g6 with the same songs, same Playlist, same Spotify account, is not as good as it was with g2. So I did a short research and found a thread in the net where people reported the same problem.
A guy from the thread suggested to disconnect all other Bluetooth devices from the phone (like smart watch or band) and actually that solved my problem. I have MiBand2. Once I disconnected it the audio quality became as good as before.
So guys, if you have a smart watch, try to remove it and check the quality again. I hope that helps.

I went a couple of months with no issues on my Kia Optima, then suddenly, I started getting really bad aliasing on the highs. As said above, I turned off my Huwaei watch and the sound was normal again. After a bit, I turned my watch back on, and it remained fine.
I had it happen once again many weeks later; and again, a quick off - wait - on, cycle with the watch fixed it. So whatever it is, seems to be a bandwith allocation issue with the bluetooth software. From March '17 thorugh almost Sept '17 and I've only had to do this twice? I think I can live with this.

Hey heres something for you to try..
Download WiFi Scanner from App Store.. Look at your 2.4ghz networks.. then keep in mind your cordless phones, IP Cams, Walkie Talkies, baby monitors in your area.. You may be a victim of signal interference.
Bluetooth operates on the 2.4ghz spectrum along with a TON of other devices now available.
Your sony stereo may be the culprit.. if is an aftermarket "Xplod" deck
Im an audiophile, and my G6 runs better than my Samsungs.. (also no issues with the "preventative volume warning"
What you also may have is an app that is causing the volume to lower...
For example.. when i stream the music player with the stock app, sometimes Snapchat notification sounds cause the rest of the volume to be lower..
Google Maps is another one that can hijack the sound but you can control in settings.
For using music try a different app ( i use Maple Player) and it works great ..
Based on your experiences i think its something outside causing the problem to be honest. but thats ALOT of trial and error to deal with.. if worse comes to worse- you can always get an aux jack bluetooth adapter for your car stereo if it IS the stereos bluetooth receiver .
