WiFi not working while on call with Bluetooth headset - Nexus 4 Q&A, Help & Troubleshooting

Has anyone had this issue? Anytime I'm on a call with my Bluetooth headset I can't use WiFi it won't scan or connect. When I switch to phone speaker or earpiece it connects. Also when I'm listening to music with Bluetooth it connects just not when calling.
Thanks for any reply.

I have a different issue with Bluetooth. Whenever I turn on Bluetooth and am done with it I turn it off. The next time I want to use it I try to turn it on and the on toggle switch toggles to the off position. It won't turn on until I reboot the phone. Then it's on as soon as I reboot. When I'm done with Bluetooth I turn it back off. Rinse, repeat. Any body got any ideas? Hopefully the op doesn't feel I'm highjacking his thread. I just haven't seen any other post relating to Bluetooth troubles on the Nexus 4.

Yup having this issue. WiFi connectivity does when on a call using Bluetooth. Connect to a 5ghz WiFi network so both can work together at the same time or hope Google will fix it.

Having done a small amount of digging around trying to figure out why I can't use my 2.4GHz WiFi at the same time as a Bluetooth headset, it looks like it's most likely due to the change of Bluetooth stack in 4.2.x.
Bluetooth has a feature called Adaptive Frequency Hopping that is supposed to automatically detect which frequencies in the 2.4GHz range are being used by other services, such as WiFi, and then avoid them. My wild and uninformed guess is that this is not working correctly and hence the Bluetooth and WiFi signals are interfering with one another to the point that neither can operate reliably. Fundamentally this is likely to be the same for headsets used for voice calls as well as basic audio playback.
If I switch the N4 to the 5GHz radio on my AP then everything co-exists happily and fluffy bunnies hop around peacefully in flowery fields.
In my case it certainly doesn't just affect streaming audio. If I play a local music track via my Bluetooth headset or speakers, the WiFi connection will usually drop; though even if it doesn't, it's not possible to download any files for example.
I have also tested on a Nexus 7 running 4.2.1 and, whilst it seems this can just manage streaming audio, as soon as I start to download a file the BT audio stutters very badly. That could also be down to the poor I/O bandwidth, though, and I'm not in any hurry to downgrade to 4.1 to prove the point at the moment.
Final test was on an ASUS TF300 with 4.1.1. This happily streamed audio over BT and downloaded a file at the same time. Also no problems playing a local track over BT whilst downloading a large file using WiFi.
There are a few related bugs open on the Android bug-tracker, for what that's worth. There are a massive number of Bluetooth issues overall, but a few WiFi/Bluetooth ones are:

It also happens when using a Bluetooth game controller, the WiFi stops functioning properly!

A2DP issue?

Until today, I've been using my nexus one to play music in my car with no issues ... I got the galaxy tab car mount yesterday so that I can use my tablet. I noticed that the galaxy tab will 'skip' while playing music over Bluetooth. I haven't noticed anyone complaining about this....
Rooted T-Mobile galaxy tab
Sony xplod mex-bt2800
Like I said, works just fine with my nexus one. Does anyone know why it would 'skip'?

Thats odd, I had this issue with some old android phones when wifi was enabled and playing music through bluetooth. But I havent had that issues with the vibrant or the tab. The old phones would skip when it scans for wifi networks. I forget where the setting is, but you could adjust how ofter it scans for new wifi networks which would decrease the amount of skipping. Try turning off wifi while listening via bluetooth and see if the issue goes away.

Yep I noticed this the other day when using the Tab to send music to my car stereo via BT, very annoying!
I also have an HTC Desire and it doesn't have this problem...
I listen to audiobooks several hours each day and the tab does not skip for me.
Except between the chapters because the headset shuts off for half a second but i can prevent that with another app that plays sounds and has its own mixer which i set to 0.
@schmolch, It doesn't skip when I'm using wired headphones or the speaker, only when Bluetooth is involved.

I'm not sure if it's the same as your issue, but mine seems to cut out every once and a while when streming. Seems to only happen when another process is being accesed. It's like BT is on the bottom priority for CPU and Mem.
I have 1 1/2 hour comute to work and before I start the Pandora stream, I stop all other programs from running. Even when 'Sync', well Syncs, it will cause he BT to cut out for a moment.
Good Luck

I have no stuttering, if that's what you mean.
Only bug I've noticed with BT (and I don't even know if this the manufacturer's fault, or the rom I'm running), but sometimes after I turn off bluetooth, sounds that normally go to the rear speaker (like music, the alarm clock, etc), will instead be piped to the ear speaker.
But a simple reset, or going into and out of bluetooth mode usually fixes that.
Make sure that WiFi is off too, that will also make the stream skip.
I have noticed that if wifi is turned on, but not connected to any networks, then the bluetooth audio will cut out every 30 seconds or so for half a second (when the epic scans for wifi networks). If wifi is off, or if it is connected to a network, I never have this problem.
This was bothering me when I used my phone to listen to music in my car. So, I used Locale to disable the wifi whenever it connected to my car stereo. Problem fixed!
Hope this helps
How did you guys get the music to stream over bluetooth?

I have this same issue. It's only on the Froyo beta ROMs.
I have all of the problems above described. The music player issue does not get better when i turn off every running process, including wifi, gps, etc. Same thing with bluetooth or playing from the earpiece. I was hoping that the OTA 2.2 release would fix this because of "enhanced bluetooth support", but i didnt realize it was happening with just the music player alone (at first i thought it was only bluetooth that I was having the problem with).
Does anyone know if this problem goes away if you download a third party music player such as Winamp or one of the others?
I am running 2.1 DI18, rooted FWIW.
Only with Last.fm does it skip. Sirius, Pandora and slacker all play fine. However remote controls don't work with Viper version c.

Your headset has to support media media audio routing.. a2dp I think is what its called.

+1 heavy like Flash Player. I noticed that if I have my BT headphones going, the flash video will stutter like a sumb!tch and it slows the vid to less than half speed. I've noticed this on any and all dk28 roms I've tested. I wish this could be easily fixed.

[Q] Bluetooth Headsets

I haven't been able to get either of my Bluetooth headsets to work with my N7. But before anyone asks, yes, I have searched the forum for answers but there doesn't seem to be any consensus on how to solve the problems.
I have the stock 4.2.2 ROM, unlocked and rooted. Bluetooth sees and connects with both of my headsets, each of which work with my Mint 14 desktop, but the only sound I get is an occasional clicking noise. Pretty much as if all of the audio is being clipped. Also, once a headset connects, I do lose sound from the internal speakers, as expected. But disconnecting the Bluetooth doesn't get it back. I have to reboot to get sound back.
My question is this: Is my problem due to the N7 having compatibility problems with some headsets or is this a universal problem. IOW, does anyone have a Bluetooth headset connected where both the mic and earphone work? And with all or most apps? I'm primarily concerned with having something to work with MagicJack.
I use my bluetooth headphones to listen to music. I just tried using Google Now with it (I put my finger on the normal mic so I would know which mic it was using) and It seems to work okay. Idk if it is the headphone or the connection but it took me two tried to get it to play music.

I just oredered a new headset off eBay that claims to work with the N7. We shall see.:fingers-crossed:
I'd like to know which Bluetooth headsets are known to work and on what models of N7 (grouper or tilapia).
If I understand correctly, an N7 wifi-only (grouper), will only respond to Bluetooth headset button presses and voice input if you modify the bool.xml file in framework-res.apk? Can anyone confirm that any Bluetooth headset will work (button presses and voice input) on grouper without that mod?
I've used my Bluetooth headset with my tablet without any tinkering, i didn't do much with it but it easily played/paused and changed tracks in Google Music. I've got Kinivo BTH220 headphones (yes they're cheap and are probably knockoffs. These had more details than the Artics or any other lookalikes and they work well enough for my needs) and a rooted stock N7. Oh and if your headsets giving you trouble check the pairing type under bluetooth settings. My phone has a habit of sometimes only pairing phone audio not media audio.

My Sony DR-BT22 headset has always worked great with the Nexus 7 providing I do not use the Wi-Fi at the same time. I am using a custom ROM but they worked fine with the std one.
All the headset controls work as well, pause. volume, rewind, skip etc.
But I have never needed to use the mic.
There is an issue when using both BT and Wi-Fi together. Either popping and stuttering BT or greatly reduced Wi-Fi speeds and erratic connection.
I posted about it here, but got no response....

I'm using a set of Motorola s10 Bluetooth headphones on my nexus 7.
I'm currently on the paranoid android Rom.
They work great out of the box.
All buttons work, I haven't tried voice commands though.
One thing to look for is some headsets will only pair to one device at a time.
In order to pair them with another device you have to factory reset them.
My particular headphones allow you to pair with one device for phone calls and a second device for music only.
But beyond that they require a factory reset to pair with anything else.
So if you already have them paired to your desktop you may need to reset them before pairing to your nexus.

I have the same and they work. There was an issue with WiFi and Bluetooth at the same time. Try disabling WiFi and see if you have any better luck.
If you do, the only way I've found that corrects this is to go back to stock 4.1, relock, update to 4.2 normally, then unlock, flash cwm, and go back to your 4.2 custom rom. Nothing else worked.
I had troubles with Bluetooth headphones and controllers when using WiFi yet they paired and worked perfectly on my sons stock 4.2 N7.
After going back to stock and reflashing the same rom/kernel combo, it magically started working. Try that.

[Q] Can anyone use a logcat to help diagnose Bluetooth issues on AOSP?

All AOSP ROM's that I've tried have a weird Bluetooth connection issue for me.
Scenario is that if I'm in my car listening to any music app on my phone, streaming the music via bluetooth to my car. And if I power off my car, wait a minute or two and then power on my car again, I don't get any more music over bluetooth. Even though Bluetooth still says it's connected to my car stereo.
To get it working again, I have to turn Bluetooth off, then turn it back on again (or reboot phone). This happens with both my car stereo (JVC) and also my standalone bluetooth receiver.
I've attached a logcat in case anyone can help me figure out the problem or maybe a workaround.
The cm10.1 based roms currently have this issue. It's across many platforms. It's not your device. You'll have to wait until this issue is fixed.

Bluetooth issue

Hi i use bluetooth in the car I have the phone connected to a 3.5mm bluetooth receiver and the built in hands free in the car.
I only switch bluetooth on in the car.
Noticed today that my battery was going quite quick and checked the wake locks.
Shows bluetooth_timer and I think a couple of others. Even though I had disabled bluetooth from the notification bar.
I then tried playing a video from the Android central app and noticed the audio was defaulting to bluetooth (despite being disabled)
Used YouTube and again audio being sent to bluetooth, YouTube app gave me the option to change to speaker.
Had to reboot my phone for it to stop thinking the bluetooth was an option for the output.
Any one else with experience of this ?
