[Q] Bluetooth issues - LG Optimus 4X HD

[Q] Bluetooth issues - LG Optimus 4X HD

Hello everybody,
I hope this doesn't repeat an answered question.
I have a well maintained p880 (stock JB, rooted, frequently factory-restored).
I tried to connect to a bluetooth audio receiver. Connection is easy but the sound breaks very frequently. This is clearly not the receiver's fault because sound transmission from an iPhone or a laptop is perfect.
I have no reference to the phone's bluetooth capacities because it's the first time in 2 years that I try to use it.
EDIT: I just found out that turning off wifi solves the problem. This, however, is not really a solution.
Does anybody have any experience with it? Is there a way to improve bluetooth performance?
Thanks!

Im on Beanstalk and the Bluetooth connection with a car radio does break as well very often (about every 20 secs), WiFi is turned off always. Maybe it's the Bluetooth chip itself that has such bad connection.

Bluetooth Stereo Headset and WiFi Problem

I found a problem with my kaiser phone last night. The problem is that if I listening to music with my bluetooth headset I am not able to connect to my WiFi at the same time. This problem is specific to A2DP because my headset can be connected to my phone and I can not browse the web with WiFi. Has anyone seen this problem before? Has there ever been a resolution for it?

I've seen this too -- when using A2DP, the WiFi connection goes down & won't re-establish itself until I turn off A2DP. I haven't found a resolution yet -- not that I'm looking for one as I almost never use A2DP, and when I do, I'm in the car, where WiFi isn't too useful.

See my post here which may be a related problem. I assume you have the same new HTC ROM: http://forum.xda-developers.com/showthread.php?t=396409

I have a similar issue. If I am streaming music, from my HP media server, over wifi and using my Plantronics 590A bluetooh headphones, after each song I am asked to log back onto the network and as each song comes to an end my device starts to search for a network connection. I don't have this issue when I use wired headphones. Clearly there is an issue when both bluetooth and wifi are used at the same time. I don't know if it's hardware or software but I'm not happy about it.

HTC TyTN II (Kaiser/P4550)
Rom ver: 1.82.707.0 WWE
Rom date: 11/03/07
Radio ver: 1.27.15.32
WM 6 Professional
CE OS 5.2.1620 (18125.0.4.2)

It's normal. Without going too technical, WiFi and Bluetooth operate on the same frequencies. They will live together if they're not using too much bandwidth, but if the usage is heavy there will be problems.
A BT stereo headset represents a lot of data to send and thus bandwidth usage, which means the BT will use the spectrum heavily, stepping over the Wifi. Due to the many packet losses the Wifi connection cuts.
Other way around, if Wifi is under heavy load, Bluetooth might drop.
Nothing we can do, that's what happens when you pack 2 radios operating in the same frequency band so close to each other, or even maybe sharing the same antenna which might be the case in today's phones.

It is absolutely NOT normal. The reason I know this is that VoIP over WiFi has been running almost perfectly on my TyTN II for a year, until I installed the latest ROM by HTC which broke it.
I used to get no crackle on Bluetooth calls with WiFi turned on. Now I do.
I used to get great quality VoIP. Now it is beyond unusable.
Simply, their new ROM broke it. BT and WiFi used to live in harmony, until their buggy ROM came out the other day. I think there are many users who know this, and who expect a hotfix soon.

You're talking about calls, I assume using the BT headset profile, while the other people in the thread are using A2DP wireless stereo. They're very different in terms of bandwidth.
On mine the headset with WiFi is also fine, but not A2DP. You're apparently not having the same issue than what is mentione in this thread. Yours might be due to the ROM, but the A2DP thing is more likely to be related to what I explained. I could myself experience it with several ROMS (all WM6, never tried a 6.1).

My old TyTn II worked fine with BT and WiFi on at same time - never a problem. I always had WiFi on at home for emails etc... and always have my BT headset (Plantronics 8XX mono) working as I hate holding phone to my ear and get a lot of calls.
I recently bought another TyTn II and then unlocked it using advice form this forum (many thanks to all BTW!) and installed latest HTC rom and WM6.1 etc... Now I love many aspect of the new ROM but I can't use BT and WiFi at same time.
So from my experience it MUST be the new HTC ROM software issue.

Okay, chalk me up as another victim of this Wireless + A2DP = Crap Reception. I've tried three other Radios and the effect is the same.
I was using a rom I got in about April, and I could stream music from the internet over wireless listening to it on my Pantronics 590A's over bluetooth no issues (other than battery lol). Now with a rom I got this month, I can listen to music over bluetooth no problem, surf using wireless no issue but as soon as you mix them both it's all bad. Also, I need to re-pair my headphones whenever I want A2DP, where previously I could just turn on the headphones and have them connect. Also, no headset icon in the taskbar.
It's not a CPU issue as there's no excess usage when you both have them enabled. Personally I'm going to point the finger at the bluetooth stack here.

As far as I remembered when I first purchased the ATT Tilt with my Plantronic Voyager 855 I WAS able to stream via Wifi (Winamp Remote) and use my bluetooth without a problem. It's when I started to put cooked roms in the Tilt that it stopped working correctly...
Besides, I use a Macbook Pro via Wifi only and I listen to my Itune via my Plantronic Voyager 855 everyday. If it's true about WiFi overloading Bluetooth on the frequency. Why does it work fine on the MBP?
And Finally.... to make my point...
I also have an AT&T Fuze. Works fine there. Matter affact. I'm currently connected via bluetooth to my Fuze with my Voyager 855... turned off 3G/HSPDA on the Fuze. WiFi on the Fuze using Winamp Remote to connect to my PC streaming from there. Explain that....

Has anyone fixed this problem?
I'm experiencing the same problem on my kaiser aka xda stellar. When Wifi is turned on bluetooth A2DP stereo connection is dropped.

Bluetooth driver from ROM older than JPY?

Hi guys,
does someone know, if it is possible to flash an older bluetooth driver than the one in firmware JPY? Although the speed of JPY-ROMs is great, I'm getting serious bluetooth disconnects from my car audio system. This didn't happen with previous ROMs (apart from JPX, which had the same issues). If it is possible, where would I find this driver?

Hi,
Same problem for me with Mercedes rSAP bluetooth.

+1
serious connection problem too with headset bt.

Ok, good to see, that I'm not alone. There seems to be some serious issue with the bluetooth drivers in JPY. Now, we need to find a solution. I think, if flashing Wifi drivers from older ROMS is possible (which is recommended because of bugs in the Wifi driver of JPY), the same should be possible for bluetooth drivers.

+1 same problem with Android 2.2.1 and never before with 2.2 on my Nissan bluetooth connect. Just tried to go back to JPO and no bug at all

I have BT problems with Darkys 8.0 and MySpace CarKit. I think it is a problem with JPY becouse with JPX i had no problems.
But its very funny. The problems are there and sometimes it works verry good and another day i had problems and it disconnect every times after few seconds.

So, some people seem to have problems since JPY, which didn't exist before. Does nobody have a solution?

Same problem here with JPY and Parrot I9100, random disconnects, no problems at all before. I really hope for a solution...

I also seem to have this problem. Only way to get it to stay connected is to turn off bluetooth and re-enable it on the phone.

I also have a Parrot system BTW, but the I9200.

Just thought I'd link this issue to mine which has a lot of similarities. Oh, and go ahead and check the link to a common BT bug in Android<->Car BT systems.

Sounds like my problem: Connection drops after a few seconds. Strange thing is: when I enter the car at my home adress, the connection stays. However, whenever I enter the car at my work adress, connection drops after a few seconds. Only difference I know: at home HDSPA is available, while at work, it is not. There is apprently something weird about the wireless module in JPY.

[SGS with JPY]
I don't get permanent disconnects, but the audio drops off for a second or two at random intervals. I can't be 100% sure, but I think I noticed it being less of a problem when I disabled Packet Data and also killed any processes that might be making data connections.

Still this problems with my bluetooth, no one has an Eclair bluetooth driver plz ???

I tried JS3 yesterday, but it didn't help. Bluetooth is still behaving strange.

Thanks for checking that. Is there any way to enable debug logging for Bluetooth within the OS itself? The Bluetooth options in Settings are pretty minimal.

Sorry, I just found out about ADB. I'll run the logger while connected to the car hands-free later on.

Whenever Wifi is enabled while I'm connected to my car audio via Bluetooth, I get these frequent periods of silence (about 2-3 seconds each) but no actual disconnects. Each problem correlates to one of these entries in the logs.
E/wpa_supplicant( 9645): No suitable AP found.
I/wpa_supplicant( 9645): CTRL-EVENT-NO-CONNECTION
E/wpa_supplicant( 9645): timeout (32)
E/wpa_supplicant( 9645): wpa_s->scan_interval (32)
W/wpa_supplicant( 9645): scan interval : value of timeout (32)
It happens more frequently when driving through built-up areas where there are a lot of wireless APs. Once I disable Wi-fi, the problem goes away. The problem doesn't occur at all when I use regular Bluetooth headphones inside my house, so I'm guessing it's something to do with the BT profile used for hands-free.
I'm not sure whether or not 3G packet data causes the same issue, but I suspect it might. I'll try more tests it in the car tomorrow and will get more detailed/complete logs.

Interesting. Keep us updated about your findings.

[Q] Bluetooth audio streaming problems

I've had my Nexus S for a couple of weeks now and am really enjoying it.
However, bluetooth audio streaming is proving to be a royal pain.
I am using a Motorola T505 in my car.
The symptoms are pretty consistent.
If I reboot my phone then the audio will stream over bluetooth flawlessly.
If I try to stream without rebooting the phone then it will stutter and stop randomly.
My diagnosis is that there are processes running on the phone that interfere with the bluetooth or take up memory that is needed for the streaming to work smoothly.
I have read that wifi can be a culprit, but even with this switched off I have a problem.
I know that my drive home takes me through areas with varying degrees of reception. The phone does switch from 3G to edge to gprs and there are areas where the signal is quite weak. But if this was a problem then it would have an effect whether I had rebooted the phone first or not.
I have tried installing Advanced Task Manager and using this to kill programs that are running but this does not prevent the problem. Even if I am able to get free memory up to 120mb + I still get the stuttering.
I'm determined to get to the bottom of the problem as it is just about my only issue with the phone and it is a PITA to reboot before my commute.
I am aware that there are all sorts of processes running on the phone and using system resources but I don't know what is safe to kill and what isn't.
Should I use a different task manager?
Is there a particular app which might be causing a problem?
Any ideas on how I can troubleshoot this further would be gratefully received.
I am presuming that I am not the only one who has this issue?
Thanks

I stream via bt to my car stereo without any issues all the time. What is the audio bitrate you are streaming?
Sent from my Nexus S using XDA Premium App

I stream mainly podcasts. The bit rate will be whatever the default is.
Since I first posted I have had fewer problems with stuttering. I did uninstall poweramp. That may or may not have any bearing on things.
I now find that auto connection is a bit flaky. Sometimes it will connect, other times I have to do it manually.
Overall not the best experience but very nice when it works.

I have no problems streaming audio from my Nexus S to my car's audio deck (Pioneer P7000BT) and I play anything from my music apps (pandora, slacker, etc..) to my songs in my mp3 library. If you aren't on a custom rom, perhaps trying CM7 and a good kernel could help you narrow down your problem.
My phone's setup is listed below in my sig.

I have streaming from my nexus s to kenwood kdc-x994 without any problems

Bump!!!
Brand new Nexus S owner with the EXACT same problem, it's driving me nuts.
Unless I do a reboot on the phone or sometimes just a manual disable & re-enable on the bluetooth, it will keep having 1-2 second audio drops right in the middle of playback. I have a Kenwood KDC-BT838U deck. The bluetooth connection between the deck and phone never breaks. It never disconnects or disassociates in any form as far as I can tell. It's clearly a problem with my Nexus S only because I also have an iPhone 4 and it works flawlessly all the time (just not unlimited data on that phone!)
It's really annoying that others in this thread say they don't have the issue at all. I have streamed off Youtube HD and radio stations via TuneIn Radio.
It's super annoying considering I got the unlimited data package for exactly this reason.
It's only been 4 days of having the phone so maybe I'll go try and exchange tomorrow.
Just my luck

First thing I tried!
I've moved on to cm7.0.2 and it is still a bit flaky, although not as bad as it was.
There doesn't seem to be any pattern. Sometimes it's fine other times it's not.

Interesting, I have had a Kenwood KDC-BT945U for sometime now and have used it with many different phones. My Nexus One had a very flaky connection to it, my HTC G2 connected fine but would give me audio drop outs randomly every few minutes which was SO ANNOYING, Iphone work just fine and my Nexus S works without issue also. I had assumed it was just an issue with HTC phones. Are you currently running a custom ROM? The only time I was ever able to get my Nexus One working the way it should was to use a Sense Rom.

I upgraded to CM7 and it's as bad as ever, didn't seem to help at all.
I also went through a full exchange at the store, and the brand new one straight out of the plastic did the same thing. Must be the phone itself is all I can think of.
All I have left to try is a new kernel, I can't figure out which kernel to update to if I'm using the Mobilicity AWS Nexus S

If you are having problems with bluetooth streaming and have a task killer installed... Uninstall it...
Task killers are problem makers...
Android has a built in task killer
Good news: I just saved 500 hundred bucks on a new phone by switching to XxXViRuSXxX
(So easy, a noobie can do it)

There is still no solution to this problem. I'm assuming nobody else here is using their Nexus S for bluetooth audio streaming often?
It has persisted through 2 exchanges which leads me to believe theres a problem with the hardware itself or something.
Rooted, custom kernels, nothing fixes it.
This phone is such a piece of junk, I'm hating it more and more every day

I use my Nexus S every day to stream music over BT/A2DP to my car stereo (Kenwood Excelon KDC-X994) and it works without any issues, and it always has since I got it. I've rooted it and am using a custom kernel and radio, but left the OS at stock 2.3.4. But it also worked fine with my head unit right out of the box before I made any changes to it.
I'm sorry I don't have any suggestions or solutions for you. In my own experiences it seems like certain BT chipsets just don't work well with certain pieces of BT hardware, so maybe there's just "bad blood" (so to speak) between the BT chipset in the Nexus S and your BT car hardware...?
Sorry I don't have any ideas to offer to try and help.

I also stream music over Bluetooth, the blackberry gateway device works perfectly for me, but it requires an AUX port
Sent from my Nexus S 4G using XDA Premium App

What app are you using? I saw you mentioned podcasts and I have seen this problem on my EVO with google listen if i initiate play from the head unit to continue listening. I saw this on stock and CM7. However I have not been able to replicate it as of late. have you tried a differnt program or even just restarting BT? That is what fixed it for me back then.
Hope that helps

To the Gentlemen having problems with Bluetooth streaming. I hate asking but have you tried a different device as the bluetooth receiver if possible? A lot of the users replying are using pretty nice head units and in my experience with my Golf ive had no problems. well thats lie.. i have issues with the turn by turn navigation audio not working. It cuts the music (as it should) but the navigation audio is either non existent or extremely quiet (yes ive checked the navigation volume on the device).
But yeah long story short just wondering what other bluetooth receivers you have tried. Good luck.

I have the blackberry little gateway as well. When it connects it's great (no stuttering etc), but my phone won't always connect to it when I get in my car. Sometimes turning BT on/off will then get it to connect, but it's random. The sure-fire way to get it to connect is rebooting the phone. Not sure why that is, but very annoying. Does your NS connect to your blackberry gateway every time without fail?

HTC One Terrible Bluetooth range .....

Friends ...... , HTC One it seems has a terrible Bluetooth range ....... I have a Logitech BoomBox (Bluetooth spks) and a Belkin Bluetooth receiver connected to my AVR. In both the cases, when connected to my HTC One it looses audio in just couple of feets. Specially with belkin receiver. But when I tested the same with my iPhone 4, it works perfectly, till the Bluetooth's designated range of 30 feet (10 meters) ... with both Belkin and Logitech ....
so it has something to do with HTC One's Bluetooth.
People with HTC One and having any Bluetooth audio device, please test this and report if you are also facing the same issue, Or is there something that I can try to increase the range. Its pathetic, 2-3 feets at the max. I am bitterly disappointed with this ..........
Regards.
Sammy

I think that Android 4.1 had a BT flaw that was fixed in 4.2.

so this means its more of an android issue than HTC One........ any alternatives to improve this, till we have an 4.2 update

I was using bt audio yesterday and it was horrible. I did some googling, try turning off wifi before you connect to the speakers, it solved my trouble straight away. I found if the music was playing when I turned wifi back on it would still be ok. Might help?

whew you had me in a panic here. (o; I'm still a little traumatized from my asus T201 wireless issues.

The Wifi/bluetooth issue is a drawback of the aluminum body design of the One. Bluetooth shares an antenna with wifi transmit. I believe wifi receive shouldn't interrupt bt though.

Then there should also be a problem if I switch on wifi after I connect BT. ,... in which case it works. It only creates a problem, if the wifi is first on and then I connect BT. ...... which is strange

Just for information. I had 3 htc, desire hd, sensation, onex and ALL had problem with bluetooth, weak signal, using a headset with the phone in my pocket already failed. I now have a note2 and this problem does not occur, being used in the same situation. So ....

My m7 (TrickDroid, elementalX 0.11 default overclocking and undervolting) is having the BT issue whenever wifi is on, regardless of whether I connect the BT device while wifi is off, and regardless of whether audio is playing when the wifi is turned back on. In other words, on my device, BT really really sucks if wifi is connected, period. Any suggestions other than not to use wifi if I want to use BT?
Update: My router (Netgear wnr2000v3) seems to use 2.4 Ghz channels. Any thoughts about whether swapping the router with a dual-band or 5 Ghz channel router would work around this issue?

I did pick up a new dual-band router and set up the phone to connect only on the 5Ghz band, and it worked! No more bluetooth issues at home. So if you run into this issue, a temporary workaround until (hopefully) HTC/Google provide a fix is to avoid the 2.4Ghz band.

Strangely enough, my Bluetooth range keeps decreasing with each software update. When I first bought this thing, I was generally impressed with how far I could walk from my BT speakers. Not as good as my evo 4g or 3d, but decent. Better than my gs3 and gn2.
Now I tend to make it about 5 feet or so with minor cut-outs while using apt-x. If I put my hand between the signal at 10ft, I can stop it completely. If I touch the upper-right of my phone with my thumb as I hold it in my right hand, I can kill the signal as well. Very much an antennagate going on here just like the iPhone 4.

[Q] Anyone else having problems with the 3T and car bluetooth?

Mine stutters when connected to my car's headunit. It's especially bad when in a call. Wasn't a problem with my Note 3 and doesn't happen on other bluetooth devices.

I haven't had any Bluetooth issues other than the fact it eats a lot of my battery throughout the day but that's a usage issue than anything else. I also use Bluetooth in my car while commuting around the city. If the audio stutters, that often means the connection isn't stable therefore move closer or remove anything in between.

Does playing a track before the Bluetooth connection is established make a difference?

Not really. It cuts off for a second every minute or so. The phone is right in front of the headunit so i dont think distance os the problem. The case is plastic so that shouldn't be causing interference also.

Well it seems like there was a Bluetooth fix for Mazda cars in the latest OTA, do let us know if that fixes the problem.

I'm having the same issue with Bluetooth not connecting/cutting out when it does.
OnePlus 3T
Android: 7.0
OOS: 4.0.2
Car is a 2016 BMW 328i

Not a problem on my Optima. I actually had to tune it with an equalizer app because stock equalizer raises the Treble louder then the bass. All normal now but not cutting. Had problem connecting phone automatically for a few days but went away

Use my device with a set off speakers and to connect to my in car audio system and I don't experience the problems you have, sometimes I need to stop and start my music a couple of times whilst it reconnects again if I move between devices but after that it stays connected and working.

my phone has trust issues with my car. it always requires a re-pairing whenever I try to establish a connection (means, whenever I enter the car, and try to connect, it requires me to pair the same phone again)

Working perfectly with my car. Maybe updating car stereo firmware could help?

I will try to see if there is an update for the car master today (their site seems to be down atm). I have had it work at times but it usually has issues connecting and will stop/pause sometimes out of nowhere. It's really difficult because I need a Bluetooth connection when driving but it gets to the point that I need to forget and repair my phone everytime I drive....

I just got my my OP 3T . I had issues with it connecting to my VW Passat. Then I read the following at the car's BT manufacturer's FAQ
Some versions of Android use a deviate pairing method. This can cause the problem of a failing connection. The solution is the free tool Bluetooth File Transfer (Android) for a better Bluetooth connection. It is available at Google Play. Establish the pairing once with this app and from then, everything should work as normal.
So after this app connected for the first time to the car's unit, the phones own BT software also started connecting without problems when I turned the car off and on subsequent times.
Might be worth a try.
