WiFi lag with bluetooth? - Nexus 7 Q&A, Help & Troubleshooting

Tonight I connected an Apple bluetooth and mouse to my Nexus and notices that sites seemed to not load as quickly as they do with BT off. Is this common?
Also I couldn't figure out how to get my Magic mouse to scroll even though I saw a YouTube video where one does scroll just fine.

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.

Bluetooth Range

Anyone else having issues with bluetooth devices on the atrix? I use a Liquidaux bluetooth adapter in my car with the Atrix docked in the car dock mounted to the windshield. It plays for a few minutes then the sounds starts cutting out, if I pull the phone out of the dock and move it to within a few inches of the adaptor it clears up. If I dissconect and pe pair, it fixes it for a few minutes then starts cutting out again. I tested with a pair of southwing headphones to see what kind of range i could get and was only able to get around 5 feet.
I have had bluetooth cut out a few times in my car. Music keeps playing with no working audio then a few minutes later it disconnects
My jawbone headset goes as far at 100 ft or more

The Bluetooth on the Atrix seems to be very on demand as compared to other devices. We have an HTC EVO and an HTC Aria in the household as well and they both stay connected to our Benz, but the Atrix seems only to connect when I'm about to make a call (which is all it's used for).

Completely agree with this. Whenever I turn on my bluetooth headset, it does NOT automatically connect to the Atrix. I have to manually connect every single time (Wireless Networks > Bluetooth Settings > Click Headset to Connect)/ Is there anyway to fix this?
Does anyone know if the Atrix BT is compatible with any BT keyboard, or only the one that comes with the Media Dock? I was thinking it would be convenient to use the Atrix with a Generic BT Keyboard and Mouse (which I already have), and not pay extra to get a Media Dock. (I realize I could use the Media Dock and plug in a USB BT adapter to use something like the Logitech BT Keyboard/Mouse set.)
I also wonder if the Moto Keyboard has decent keying? I have found it harder and harder to find ANY BT keyboards with decent keys lately. I really dislike the chicklet keyboards. Unpleasent to type on!
Thanks in advance.

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.

Using multiple bluetooth items with the tab at the same time

So it seems that the tab can only handle one bluetooth item at a time. I was trying to play GTA 3 on it with a bluetooth keyboard and mouse but it seems like when I have one connected and then try to connect the other the first one desyncs ( thats a word right? ) with the tab and I am stuck with the device that I connected second.
Has anybody gotten multiple bluetooth devices working on the tab together? It would just make playing GTA 3 so much better.
I've used a bluetooth keyboard and mouse simultaneously. Never tried it with a game running though. Worked great for evernote and pocketcloud.
I have had 3 going at once. Headset, keyboard and mouse. No issues.
I've had keyboard (Zagg folio), earphones (Sony Ericsson MW600s) and BT link to my Charge for Tablet Talk all going at the same time. Just today in fact. No problems with any of them working at the same time (i.e., typing an SMS with the keyboard then sending it to the phone for delivery while streaming Google Music to the earphones).

Bluetooth audio and Android 4.2

Updated my tablet to Android 4.2 this morning and afterward watching video with Bluetooth headphones it's skipped popped and just been generally awful. Curiously music works fine. Anyone else experiencing this?
Sent from my Nexus 7 using Tapatalk 2
I just tried a few mp4 clips and didn't experience any skips/lag. Can't try avi right now as mx player doesn't work in 4.2 However, it seems there has been some changes to bluetooth. If you have your volume loud enough you can hear it 'stop' using the bluetooth if idle for a couple of seconds. Never heard that before. Also, a bug that really irks me is latency with bluetooth in games. Previously, games like dead trigger would seem to lag well over a second behind, almost 2 seconds. Now it's about .5 of a sec, however it's skips,scratches etc.
Other games fair better. For example, mame has about .5 of a second where it exhibited the 2 second lag previously. Not nearly as many skips as dead trigger but I heard a couple.
Btw, is android the only platform that has this issue? I read old posts of ipad's/iphones having it back in 2009 but I believe they fixed it. My friend has a playbook and it didn't support bluetooth stereo profile (ad2p) but they released an update last year and it works perfectly. I tried a few games on his device and none of them exhibited any lag, scratchiness etc. So RIM gets it right the first time and google has had this issue on all their devices for years? There's a few bugs filed on this on the official google bugs forum opened in 2009 and no response from any developer.
EDIT:
Just tried youtube with bluetooth stereo headset, audio breaking up, stops/starts. It seems to be going quiet if there is even a moment of silence in the video. God damn it, I use this all the time and now it's unusable. This was at least one thing that worked fine with bluetooth. It could be my connection right now but I highly doubt it. I'm at home and this connection is always fine, this is the first time I've experienced this. I bought this headset for gaming, videos, and voip. Voip didn't work because bluetooth mics are basically non-usable in android, gaming has lag, and now videos won't play properly. I think it has to do with using the wifi at the same time with videos as videos downloaded from youtube are fine.
Yep this mimics my issue. Streaming anything results in choppy playback over Bluetooth. This really is not acceptable to me, and its hurting my view of my nearly brand new Nexus 7. I really hope we see another OTA seeing as I can't very well turn WiFi off on a device that relies on WiFi.

I have the skipping too with Pandora over blue tooth, but thought it might be Wi-Fi limit since I am tethering off my rezound which is playing flawlessly over BT. It was skipping as pictures loaded in emails.

It isn't WiFi bandwidth related as far as I can tell. I can buffer a video, play it, and still the audio flips out. This is just disappointing and sad on Google's part now. The same issue affects the Galaxy Nexus, as well. Did no one even bother to test this before it rolled out??
I've been having the same problem since the 4.2 update - the bluetooth issue is definitely linked to wi-fi (no skipping on downloaded video while wi-fi off; skipping as soon as I turn it on). Online bluetooth streaming of any audio whatsoever is basically ruined.
I thought maybe changing the channel on my router would to the trick, but no dice. Google was very sympathetic over the phone but completely unhelpful - "this is the first we've heard of this."
I've only been an android user for a few months. Are they usually pretty good about addressing stuff like this?

bluetooth now working
My bluetooth headset (Samsung) was stuttering the other day as many people are reporting. I did play around with the settings and at this point I have no idea why, but it is working fine.
I had done 2 things:
1. I unpaired every device and re-paired them
2. On the wifi advanced settings, I set it to never sleep and disabled battery optimization
Bluetooth then worked fine using Pandora and TuneIn radio. I changed the advanced setting back to optimize battery and all still works.
Now extremely happy with 4.2 but baffled as to why it now works.
I am going to test more but I read it from someone else and it seems to have helped me, is to disable gps. Others said it didn't work for them so maybe it depends on the bluetooth device as well. But with gps disabled youtube no longer lags/skips and stays in perfect sync, but I'm going to test more.
And with gaming, it's almost in perfect sync, however some games still skip a bit and some lag more than others (mame4droid seems to lag the most). Whereas before 4.2 all games had almost 2 seconds delay in audio.
So in some ways, bluetooth is actually better in 4.2 in that they seem to be closer in getting the lag in realtime apps (games) working. So I hope their fix is not to simply revert to 4.1.2 bluetooth.
Anyway, try disabling gps, it may work for you.
To all those who are trying to use Wi-Fi & Bluetooth, Good luck!
They both work at 2.4ghz frequency most of the time you will only able to use one. Unless you're around 5ghz wi-fi.
I got lag and werid things when my music player (Play Music) tried to play .avi file
It is not BT that is broken in 4.2!!!
First of, 4.1 was working fine with my BT audio, got the OTA update and it was still working fine after first reboot... couple of days later mine started to act up...
It was almost impossible to listen to BT audio... but BT is not the problem!!!
It is either the Audio Effects service/program or Google Music... easy to test...
Connect the BT audio device, go into settings, apps, running stop the Google music service, stop the audio effects thing... BT audio does not skip at all anymore... It is as flawless as it was in 4.1... so the BT is not broken i any way... it is either the audio effects service or the Google music stuff...
I hope someone will fix it... but it is not BT that is bugged...
