Does BT and Wifi interfere with each other? - Upgrading, Modifying and Unlocking

I recently bought a x51v and upgraded to the A03 ROM. I did the broadcomm BT stack and can get good audio quality with Wifi off. When I turn Wifi on and I want to hear a streaming video I get a lot of skipping on the audio. I did the registry hack and even the A2DP fix, but it still happens. Is it because Wifi can interfere with Bluetooth activity or is it a problem with the BT Stack?

Hi there,
I suspect there may be some kind of interference. I thought i'd try it out by putting a USB Wifi dongle and a USB Bluetooth dongle next to each other, and tried using them both simultaneously, and both kept dropping out. But when i seperated them, the dropouts stopped and speed went back to normal. (although i'm sure it's not recommended to have them right next to each other haha)
Anyone else seen the same thing?

I do see a bit of trouble with A2DP & WiFi on my Tytn II -- when using A2DP, the WiFi will occasionally disconnect, and the reconnect will cause sound to drop out momentarily. This happens only with A2DP -- the other profiles (handsfree, HID, etc.) don't use enough BT bandwidth to kill WiFi.

Wifi + Bluetooth Simultaneously

OK, I know this is an Android problem from my past experience. But is it me, or are others having this problem as well?
Problem:
Wifi connection on and working.
Bluetooth headset on. I turn on bluetooth, connects to headset.
Wifi connection gone. Wifi still on though.
Bluetooth connects. Music plays.
I force a reconnect with wifi router.
Music starts skipping, controls become jerky. Wifi becomes unstable.
Disable wifi by turning it off completely. Music streams beautifully with full controls.
I'm on my Omnia 7.
I also have another problem with Bluetooth. This thing gives me static interference all the time when in the car, but I think that's a wifi thing. I usually have wifi + bluetooth +3g on all the time. Gonna try in the car without wifi on from now on.
I tried this yesterday but both bt & wifi worked without problems. In regards to static BT in the car.. I have that on occassion with my Smsng Focus. At times I get crystal clear audio (cd quality) when i stream audio to my bluetooth enabled cd deck.. and at times.. there is static or loud hissing in which I'd have to disconnect and reconnect bluetooth a few times before the distortion goes away.
I read somewhere that it may be caused by 3G connection consuming more processing time than BT/wifi or how the priority is setup in the drivers.. don't quote me..it was something I read a while back.

[Q] bluetooth issue?

Is any one with problem for the bluetooth connetion? It will drop after a few min. and try to reconnect have no respond, need to reboot the phone. Is it the setting or bug?

Mine has not done this with my Jawbone Icon, Motorola S10-HD stereo headphones or my Volkswagen Tiguan. Perhaps you might try another bluetooth device?
buletooth issue?
I had try different device and do the same thing, like my audi q7 and jarba headset and the garmin. Can you tell me what buletooth setting you are using?
Mine has intermittent issues as well, I'm using an older Motorola 710 BT earpiece. I'll only turn on BT on the phone when I know I'm going to use the earpiece, such as when driving or needing to be hands-free. I only activate the earpiece after enabling BT on the phone, but there are times when the earpiece does not connect.... the only fix is to reboot the phone. Is that similar to the issue you are having?
I'm having issues connecting to my car. If I reboot the phone and connect it will work. But once it's disconnected and I turn bluetooth off and then back on from the phone, it will not connect. Only way to fix it is to reboot. Don't know how to fix the issue. Never had a problem connecting my Sensation to my car's bluetooth.
My issue is similar in turning bluetooth on and off via the power widget and not being able to re-connect to my bluetooth earpiece after a few cycles. I'm wondering if it may be an issue with it being BT 2.0 versus BT 3.0 on the phone?
I thought it was my car but a lot ppl is having this issue too.
Sometimes it wont connect but it says connected so i have to go to BT settings and click where it says connected n overwrite the connection for it to work if not gotta restart the phone. :/

I'm having problems with a SoundFly FM Transmitter in my car.
At first it took forever to pair. And even when paired & connected it's really glitchy.
I'm using this mainly for GPS turn by turn over the car sound system. But because it is glitchy I can't use it because some of the directions get cut off.
I had a MyTouch 4G before. No problems whatsoever. I don't if it's a hardware or driver or BT device issue.
I'm willing to get a new FM Transmitter but not if it does the same thing.
It didn't work well on stock or rooted w/ Juggernaut rom
this is quite annoying. I wonder why this topic died so quickly, there have to be more people with this problem? Maybe has something to do with a bluetooth power saving sleep feature? Streaming music, pause music for a few minutes, incoming call gets connected but I get no sound through headset.

[Q] bluetooth audio issues - intermittent

Hey everyone. Gotta say, i love this phone its the android device i always wanted. However, im having issues with my car bluetooth which i have not experienced before... namely, that random phonecalls sound completely digitized.
Ive come from an htc desire and htc sensation on the same car without issue and am worried i got a bad BT antenna-or its software...
Anyone out there experiencing the same thing? Any advice (other than buying a new car)?
I am having the same issues on a Verizon Galaxy Nexus V4.02. If I turn bluetooth off mid-call the earpiece sounds fine. The static only happens during voice calls, streaming A2DP sounds fine. There are bluetooth improvements listed in the 4.03 changelog, hopefully this will be resolved.
I had some problems with my BT speaker phone. I turned off the key press sounds and the screen off sounds and that pretty much fixed it.
I have an off topic question for you guys that use bluetooth streaming. Can start the car and press play from the HU to start music? I can with my old D2, but not my TB. I have to actually start the music player on the thunderbolt, then I can control it from my HU. I would like to upgrade, but I don't see a huge advantage in upgrading if I still can't start my music without having to actually take the phone out of my pocket. (Yes, I know it's stupid, but I'm lazy.)
I have this same issue in one of my cars. I ran a number of tests and the issue only occurs on my vehicle when the phone is connected to both for telephony and a2dp music. The static occurs whether or not a2dp is actually being used to stream music or not. This particular vehicle has two separate devices for music and telephony. If I unpair or disconnect the music device, then telephony works without the audio distortion. As soon as I reconnect the music device, the static is re-introduced.

I am experiencing this issue as well and have not been able to resolve it. I've tried disabling the touch sounds, screen off sounds, etc. but to no avail.
It pretty much makes handsfree unusable while driving. What have you guys done in the meantime? Have you been able to resolve the issue yet?
Here's my specific details:
Phone: Verizion LTE Galaxy Nexus v4.02 stock/unrooted
Handsfree Car System (phone audio): Stock 2007 Audi A4
Separate A2DP Module (media audio): Dension Gateway Five connected to factory Stereo
All of my previous phones (Thunderbolt, Droid X, Incredible, OG Droid) have fully supported this setup with no issues whatsoever.
On a sidenote, my A2DP streaming is also unreliable. It first has trouble connecting to the device. If/when it does, audio constantly cuts out when streaming Pandora, Slacker Radio, Google Music... pretty much any streaming over network connection. I have not tried locally stored music yet as I don't have any currently stored on my device. Are you guys experiencing this A2DP issue as well?
I wonder how widespread this is and if it warrants opening an official issue with Google.
I used to have a Blackberry Torch, and I have a Ford Mustang. When I would connect the BT to it, if the Wifi was on, it would "interfere" with the signal. Turning wifi off, fixed the issue. This was a widely known issue with the Torch. Granted that shouldn't have to be a fix, but can any of you verify whether your wifi is on? (regardless of if its connected to anything or not). I'm wondering if the Nexus is using the same BT/WIFI chip that the Torch used.

I appreciate the suggestion but unfortunately, I have the issue even if WiFi is off (I never use WiFi).
I'm going to try and toggle a few of the sound and haptic feedback settings a little more to see if it's pertinent to a certain on/off configuration. It's a shot in the dark but I'll try anything at this point.
ok it was worth a shot. Maybe on a whim turn off 3g/data so basically its airplane mode except BT is on? Just to eliminate any RF interference. Other than that I dont know
Spent quite a bit of time in the car today to try and pinpoint a cause and I have had no luck.
Phone audio will sound great and then all of the sudden turn digitized and distorted for a random period of time, then revert back to sounding great. One thing to note is that the distortion is both ways - the person I'm talking to also hears it when I speak and cannot understand what I'm saying. It's very frustrating not being able to use this feature.
I am on my 2nd replacement phone and ALL of them have had this issue (returned two others to VZW due to this issue and the speaker clicking issue). I am still wondering if it is software/OS releated or if it's due to poor hardware.
Quick Update (kind of):
I messed around with more settings last night. I am happy to report that after I disabled NFC last night, I made several handsfree calls in my car with perfect clarity and no issues. Also, A2DP streaming Pandora worked flawlessly! I was happy that I thought I pinpointed the issue - NFC interference.
BUT this morning, I made a handfree call and it was immediately distorted. Frownie face! A2DP Streaming Pandora still worked great. I am now trying to determine if my success last night was a fluke or if something is different with the phone this morning. The only difference from last night to this morning, that I have been able to identify so far, is I now have the extended battery in the phone. Last night's success had the standard battery. I'll switch them back at lunch and re-test.

I've got the same issue. Even with NFC disabled. Makes listening to Pandora in the car unbearable. I've gone through the same steps as you, but hasn't exchanged the phone yet. I've had previous Androids and it was a hit/miss with the distortion, but with an iPhone or BB never had this issue. Go figure.
thanks to all the replies, will update to 4.0.3 and try out some more options.
- unplugging my music dongle had no effect on call quality
- NFC on or off had no effect
I also find that the music adapter never auto-connects and needs me to go in to the BT settings page and manually select it.
thanks all.
Hello again. So I have an update that adds to the flakiness ...
Updated to the Bugless Beast ROM and Franco's kernel. My intent was to completely reset the phone and hopefully get a new Bluetooth stack in the process.
Initially everything paired OK, but after a while my audio randomly disconnects after about 20minutes and then reconnects depending on its mood.
My phone connection is more controllable now: if the BT is enabled on my phone when I turn on the car, the sound quality is entirely digitized and unusable. If I turn on the car and THEN enable my phone, the sound quality is flawless every time.
Still not ideal, but manageable. For the music audio part, I lay the blame entirely on the Audi Music Interface BT adapter: the thing is crap and always in pair mode even with the car turned off! The telephone BT in the car head unit has seen several phones pair with it without any issues (I do mobile development so I get to play with many phones) so in that case, I can't blame anything but the Nexus.
I really hope someone at Google or Samsung reads these threads since it would be tough to troubleshoot, but there's no doubt an issue exists with general BT compatibility.

Anyone have an update on this issue? Does anyone know of a ROM with a different Bluetooth stack than AOKP? I love everything else about AOKP. I have had the same garbled bluetooth audio from stock - 4.03 with franco and faux kernels with the same result. I had similar problems with Cyanogen 7 ROM I was using on my Incredible the week before I bought the Nexus.
Update - I experimented with a couple of additional devices, and the multiple connections problem with my Nexus is limited to A2DP only devices.
I am now using a Garmin BlueTrip with "phone audio" deselected in bluetooth options. As long as the additional bluetooth device is handsfree profile capable, the A2DP functions perfectly, calls are clear, and the device reconnects after a power cycle consistently. I'm glad this appears to be a software issue and not something we will have to live with for the life of the phone. I'm sure a future update will correct this issue.
I'm also having a problem with Bluetooth calls sounding very digitized and/or choppy. It is bad enough that it can be extremely difficult to make out what the caller is saying. A2DP, on the other hand, has performed pretty flawlessly and the device consistently reconnects each time I get in the car (although it can take up to 30 seconds or so).
I'll have to do a little experimenting with some of the settings mentioned in this thread to see if they have any affect.
On a related note, I feel like sometimes calls made/recieved on the handset can sound digitized as well (although not nearly as bad as over bluetooth). Has anyone else experienced this?

Bluetooth A2DP Audio Stream Issues

Hey Fellas,
Coming from a Note 2, I instantly loved the form factor of this phone. Built well
I'm having some issues connecting my bluetooth and streaming music on it.
My receiver is a Tunelink bluetoothwireless and the programs i'm using on it is mainly spotify. I did try beyondcast, but still having the same issue.
When streaming music or any sort of audio, I'm getting very spotty audio output. I would hear a slight static, then it'll cut out and resume at a different location. It seems to me that there is somekind of lag that goes into the system.
Calls made through my car does not have these issues. I've tested the tunelink and it seems to work fine. Anyone else having this issue?
I'm not understanding where its coming from. A possible fix would be greatly appreciated
Thanks
There seem to be issues with the bluetooth on this thing. Another forum member and myself both have problems staying connected to some of our bluetooth devices. I can connect to my car without any problems, but I can't connect to my bluetooth enabled housephone properly. If I try to make or receive a call, it's instant disconnection.
I'd lump your problem in with what's been described as faulty software.

Yep. And my car will stay connected for over 2 hrs, through phone calls and hangups; never an issue. Then when connecting to my home phone, it's disconnect-mania. Most people don't seem to have problems, but some, like myself, certainly do.
And the reason I blame it on the LGOG is because my old phone (LGOS) always had a solid connection to the home phone. Only thing that changed is my cell.
I have no problems streaming, from a motorokr s305, a nokia bh-505, and a JVC unit in the car. I do get somewhat of a poor connection with the motorokr s305, though. I just figured it was the age of the headset itself.
I do not have issues with my LG stereo Bluetooth, and with my Kenwood head unit, my only problem seems to be auto-connecting. It also has some skips, which has happened on all my phones since I got the head unit. Need to updates its firmware and see if that helps with any issues.

[Q] Problem with Bluetooth headphones and YouTube buffering

Does anyone have a problem with constant buffering when playing YouTube videos (especially HD videos) from the YouTube app while having Bluetooth headphones (or speakers) connected?
This problem seems to only occur when I use Bluetooth and wifi together, as this problem does not happen when I use wired headphones or view videos stored on an SD card. But I can stream Spotify audio while using the Bluetooth headphones without any problems. This makes me think that my wifi connection is slowed down when the Bluetooth headphones are connected, and YouTube videos keep buffering because the tablet cannot download the video fast enough. Is my tablet defective or is this a common bug on the Samsung Note 10.1 2014?
I also have problems with YouTube app...even without bluetooth on. I also have this problem with other bluetooth devices, like my bt keyboard and mouse....

Have you ever reset your bluetooth headset or speakers. It happened to me a couple time. Couldn't connect but after reset my bluetooth devices. It connected and work again. Also sometime my bluetooth headset is connecting to my phone and I m trying to connect it to my note 10.1 2014.

It seems there are some definite issues with bluetooth and this tablet and/or Android 4.3. I've noticed that my headphones disconnect from the tablet if no data is being sent to them for a minute or so, which seems to be similar to the common problem of bluetooth keyboards disconnecting fairly quickly. Although this problem isn't as big of a deal with bluetooth headphones, since data is constantly sent to the headphones.

I tried resetting my headphones, restarting the tablet, turning bluetooth and wifi on and off, but the problem still occurs. My headphones connect just fine to the tablet, and I can see in the bluetooth popup on the tablet that my headphones are connected. I can also stream any audio or video that is stored on the tablet without any problems, as well as stream audio to the headphones. The only thing I can't stream is YouTube videos. Also, these headphones work fine with the other devices I tried them on.

Unfortunately this is a known bug in Android. I am no expert and after doing some light research along the web, I am still not sure if the main problem lays on a physical interference between Bluetooth and the 2'4 GHz wifi signal, in software or in a combination of both.
Some video about this issue: https://www.youtube.com/watch?v=LbB7H0kk5MU&feature=youtube_gdata_player
I asked a similar question in a "forever alone" post when I faced this problem for the first time with my S4. You will find the link to an informative thread about this topic:

Fortunately my GN 10.1 2014 performs very well (no noticeable interference), but I think that my new router, with a wider wifi signal range, did the magic. In theory a 5GHz wifi signal has no interference with the 2.4 GHz Bluetooth signal.
I hope it helps

Thanks so much for the info and the links! I didn't realize that this was a known Android issue. I hope Samsung or Google can fix the issue in the future, although it seems like it has been occurring for at least a year, and it is not clear if it is a software or hardware issue. I'll try using a different router next. My current router is pretty old and doesn't support 5 Ghz, so :fingers-crossed: I'll be able to use bluetooth headphones and watch Youtube videos together.
Thanks again.

I have had the same problem with a bluetooth keyboard and mouse not working correctly, I found if I turn off the wifi radio on p600 I have up to 3 co current bluetooth connection going at he same time. when the wifi is on and active the bluetooth is dropping off think it has to do with wifi 4.0 radio in the tablet or the placements of the attennas in the tablet.
Same thing here
I'm having exactly the same problem. When I connect my p600 tablet to my bluetooth speakers the wifi stops working after a couple of minutes while using my tplink router. If I use my dlink router the wifi speed is greatIy reduced, I can still play "tune in radio" but the conection its to slow for youtube.
Issue RESOLVED on Windows 10 PC
I was having this problem and was breaking my head trying to understand why this was happening...I tested a set of Bluetooth headphones that had no mic and they worked fine, it was only my Bluetooth headphones with a mic when this would happen.
After so much troubleshooting I found that my Bluetooth headset was registering as both a headset and headphones and Windows was enabling the "headset" as the default communication device and the "headphones" as the default playback device. When both were active it made all streaming online videos buffer and never play.
When I disabled one of them the videos started to playback fine after one of the devices was disabled. Hope this helps in some way but I think it is the way the Bluetooth headset is registering as two different devices and causing a conflict. I wouldn't know how to fix this on a Galaxy Note but there may be a setting in Bluetooth connections where you can see this happening in Android like it does in Windows.

thanks this saved me some efforts...I am facing this issue with my Sony TV and Bluetooth speakers.. so was wondering how did it work before and started facing issue now. When I switched to 5G WiFi the issue got resolved. So previously when it worked I must be in 5G WiFi and face this issue when on 2.4G WiFi
