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

Does the nexus have a weak bluetooth reciever? My audio keeps skipping.

I have a Motorola S9 bluetooth headset which worked perfectly with my blackberry 8900. I'd have the phone in my pocket, go to the gym and listen to music, it would work great.
But on my Nexus one, ever since I got it in Febuary, any rom i've ever been on (enomther, cyanogen), the audio skips repeatedly if I don't keep the phone like half a foot away from the headset (which is impossible unless I strap the phone to my upper back or something). It will cut out for 1-10 seconds and then return for a second and then go out again, and then be steady for 20 seconds and then do it again, it's very random but VERY frequent..I've never been able to go a full minute without skipping.
I've also had to have my nexus one replaced at one point, and this was a problem on both models, so I don't think I just got 2 defective nexus ones in a row.
Also I have paired the S9 bluetooth with my PS3 and again with the blackberry and it works perfectly with both.
Is there any reason or does the nexus one just have a weak bluetooth reciever?

I'm using the Sony Ericsson MW600 bluetooth headset and I found that the bluetooth range is better than my laptop. Audio doesn't skip even if I am ~10 m way.

I have some Sony ones (the neckband BT ones, not sure of the model) and they only seem to skip if there is heavy EM interference, or if the battery is low and there is something in the way. This was the same with a Nokia E71 (which IMHO had the best radios on a handset I've used), so I think its a headset problem rather than a phone problem. But saying that, I primarly use this combo with the phone in the chest pocket of an ACU jacket, so it only has about 30cm to travel.

I use my Nexus with the S9, and it works great. I often leave the phone playing on my desk at work, while I got to the printer etc. No probs, until about 40 foot away...

Compared to my old iPhone i found it was a little weaker too.

I think you have a second defective unit. My first n1 had the same problem. Since the n1 share the wifi and bluetooth on the same chip, you should notice also some weakness in the wireless signal as well. At least that is what I found.
I would never get full bars on my wireless even standing next to the router. The bluetooth was worse, I couldn't keep my phone more than an arms length to get the bluetooth working.
I returned it and got a replacement
Hope this helps

Well I don't have problems with weak wifi signal. I can be pretty far from the wifi and get great signal. Also for voice calls the plantronics explorer Bluetooth headset I use works great. Its just the a2dp streaming on the s9 that are giving me problems.

Have you tried turning Wi-fi off while using the BT for streaming?

Blue tooth dropouts- sometimes fix
On my N1, both a Jawbone Icon and a Samsung headset will have fluctuating media sound frequently. The sound will vary in volume or skipping up to once a second, giving a very unpleasing experience. The distance to the phone can be one foot or 15 feet with the same results.
I finally correlated this to either turning on or connecting the headset after the media had begun playing, or coming back into range while the media was already playing.
I found that I could get clear sound by exiting the media, then restarting the media while the headset was already connected.
I have trouble also with going out of range, then returning into range, but the media connection not restoring, just the phone connection.

Solutions I found for this on the web were:
- set master=true in /system/etc/bluetooth/audio.conf (worked for me)
possibly also:
- turn off wifi
- carry bluetooth device and nexus on same side of your body
- use bluetooth only for media (not phone)

[Q] Bluetooth Question, multi-android build issue

Hey,
I have been playing with Android for a few months, and still not very good at it.
But one thing i noticed, regardless of the Build (think i have so far all used sd card builds, A darkstone v3, then another, now currently on CoreDroid v.8 i think). May have been another one in there.
This is my bluetooth issue.
My new Camaro and all the builds, so far, seem to work nicely kinda;
I can answer the phone from the car or phone. I can make calls, and have it routed thru the car. My bluetooth stereo, ADP2F? (or what ever it is called, for transmitting stereo via bluetooth) works fine on the car, and headsets.
The one thing i consistently notice, if there is not a constant stream of bluetooth data or packets, the car and the phone seem to disconnect. In translation, if i am listening to music etc, the connection is fine.
If i pause music, and just let driving directions transmit using navigation only, the connection probably times out and disconnects. I am forced to continually reconnect...while driving trying to navigate, makes navigation a royal pain in the A*^*.
Is there some setting to prevent time outs or disconnects? is there a patched file to load, to give me a choice to not disconnect a connection automatically?
thanks

I would also be very interested in a response to this!
I'm experiencing a very similar issue. I've also tried many different Android builds/kernels/SD/NAND and even different WINMO Roms and Radios.
Mine is a little bit worse though in that without exception, the bluetooth on the phone will 'break' after 1-2 days - meaning that it will spuriously drop a connection and will no longer function after that, i.e. will make a connection but will drop it less than 30 seconds later.
The only way I have found to fix it is to reinstall the android build.

[Q] Spotty Bluetooth Performance?

I'm able to connect my Atrix to my JVC double din in car stereo system via bluetooth and it connects and pairs just fine. The problem I have is that the music "skips" or loses sound every few 20 to 30 seconds. It plays the whole music file but seems to drop out here and there. My old tilt 2 played on this same jvc beautifully using bluetooth. But the Atrix cant keep up? It happens no matter if I play music files through the stock android music player, or Power Amp player. What gives?

I also have a JVC Kw-Avx810 with bluetooth adapter installed. I have the same problem, for calls it works perfectly but for music its a bitt frustrating to hear music skipping each 30 seconds. Sometimes I am able to hear the music without skipping and that happens when I first play the music on the phone and while the music is playing on the phone I turn on bluetooth on the phone and the after 10 seconds it begins to stream the music to the Jvc Unit without any problem. I do that every time that I wanna hear music on my Jvc unit. Havent had any more issues so far.

I use it for my ford sync and at times it will do strange things that my nokia n95 never did but for the most part it works well...

I had a similar problem when I had my streak. It was because I was pairing Audio with one device and bt phone with another. If you are doing this it will cause that. I use my Sony stereo just fine, will disconnect occasionally, but quality is great.

I use my atrix with my prius, and so far so good.I haven't had disconnect issues yet.

I think it's something JVC could probably fix with a firmware update. The atrix streams just fine to both my Sony and Kenwood headunits.

I have the same problem.

The key terms: "Usable but not stable" , although it was not tested with Atrix, it is evidenced on both HTC and Motorola phones.
Great move JVC .. you've made your product useless to me and tarnished your reputation at the same time. Couldn't get your guys to write a new firmware ... Cant get me to buy another one of your products.
The same looks very like it will be true with Motorola's Andriod phones. Both JVC and Motorola will soon be wiped off my present or future ownership map. Woooo

Mine drops out/ goes silent / loses bt connection about once every 8-12 minutes when connected to my sony head unit (mex-bt5100). I turn off bt then back on, then restart my streaming radio.

I have a jvc double din unit too. I don't experience any issues with audio... however the phone is a bit garbled when connected.
Have you tried moving the bluetooth dongle to the front USB port?
Sent from my MB860 using XDA Premium App

i Have a single DIN (AVX33), the bluetooth is built-in so there is no dongle.
I read quite a bit about this problem .. it is related to the phone hands free profile sending signals to the headunit in a way that the headunit cannot handle without disturbing audio. It is exasberhated by low signal strength (both bluetooth signal and GSM signal), and also by the fact some andriods will give equal transmit priority to these hands-free signals that it does streaming audio. This is why turning wifi off helps a little (reduces interference). The signals that are interfering with streaming audio are the ones about battery life, and GSM signal strength. As signal strength chagnes, the phone sends out a new value despite the headunit not needing to do anything with it. This is what interupts the audio consistently but irregularly
End result .. it can be fixed by software adjustment on the andriod (do not send updates when streaming audio .. unlikely with Atrix unless Moto gets their thumbs out of their asses), by software adjustment on the receiver (unlikely as JVC is a **** company that does not care about my woes), or by mitigating the problem as I appear to be forced to do. I do this by turning off the "phone" porition of the bluetooth. Or by starting the music and THEN connecting to bluetooth. Unacceptable to me but I have no other options.
I f**king hate how complex our electronics have become and how consumers are powerless to fix these problems DESPITE the fact some of them have a higher level understanding of what the problem actually is. (therefoer I will not be purchasing anything from JVC or Motorola ever again. They prevent me from solving problems and refuse to fix them for me.)

Bluetooth causing video stuttering.

For whatever reason, when I use my Bluetooth headset for audio while watching a video, it causes the video to stutter. It's watchable, but really annoying. The same videos have no issues on wired headphones or the external speakers. Anybody else having this problem? If not, any guesses on fixing it? I have a 3g Xoom on stock 3.1.

Finally, someone else acknowledging this problem. I started a similar thread a while back and it went nowhere - only solution suggested to me was to try overclocking - so I went ahead and installed Tiamat Kernel and overclocked - and no change - still got stuttering video when using bluetooth.
This problem really drove me crazy at first. Spent ages re-encoding my videos thinking it was a problem with the video itself. Then one day I forgot to charge my BT headphones, and was forced to use wired headphones and the video played perfectly. Thats when I realized what the problem was. Since then I have only been using wired headphones to watch movies and have been using my BT headphones only for video podcasts where I don't care about slowdown. Wish there was a solution. I really miss my wireless headphones for movies.
Anyway its nice to see someone else has made the same observation. I was really perplexed that no one else seemed to be bothered by this problem.

Bummer! I was hoping my problem was an isolated one that could be fixed with a reset or something. Guess I'll just start carrying ear buds around and save the headset for music.... Thanks for the reply!

I have a similar issue that I posted in the Q&A section but no real replies. For example when I turn on bluetooth to stream my music to a bluetooth receiver, I cannot surf the web at the same time because it's really slow to load pages. Once I turn off bluetooth, the wifi works at full speed.
It's pretty bad to the point where the page that I am trying to load actually times out. I thought it was my Xoom that was an issue but apparently not. It's impossible to use something like Audiogalaxy to stream music from my computer and transmit it using bluetooth. The constant fighting for wireless/bluetooth signal creates pauses and gaps. I'm thinking the same is happening to your video. Can any one confirm that this happens with another brand tablet? I have until June 13th to return this to Amazon. I already pre ordered the Galaxy 10.1 but would rather keep the Xoom with the expansion slots and usb port if I can.

I can confirm that this BT - video slowdown doesn't happen with my Galaxy Tab 7 which is a single core running android 2.2. So it makes no sense that using BT should demand so many resources that it brings a dual-core HC tablet to a crawl.

Correct. Do you mind streaming music from your Xoom to your headphones and go to a sight like Engadget to see if it is able to load the entire page?

I haven't ever really watched a video with bt headphones, but I use them all every day when listening to music on my Galaxy S and I can say that I get really ****ty network performance for web browsing, and that my phone is noticeably slower while I'm using the bt headphones. This has been the case on two different 2.2 roms and on 2.3.3.
I haven't tried these headphones on the xoom so I can't say there, but at least it's not the only device with BT issues.

I'm still having this problem...anyone else?

I'm having the same problem. Get random pauses and freezing. Guess I'm switching back to wired headphones.

Hmmm...I haven't noticed this issue. I watched Thor in 720p using the HDMI output to my TV and my bluetooth headphones the other night...no freezing or stuttering.

The problem is that BT and WiFi both use the same frequency band, and as such the WiFi/BT chip has to switch control of the (same) antenna between both halves of the chip. Now, BT audio (A2DP) is a stream, so when the WiFi/BT chip has to snatch away the antenna for WiFi (even if you're not actively using it, there's periodic stuff like beacon frames and background data, etc.) the stream gets interrupted from time-to-time, and because the audio system- which gates the playback of video streams- gets "bunched up" with data that couldn't be sent while the antenna's switched to WiFi, sometimes you get these pauses.
It's not really a CPU or processing-power issue.
When I watch movies on the plane thru BT headphones (and WiFi is off), I never get any stutters. I suspect if you turn off WiFi it'll smooth it out.
