[Q] Bluetooth reconnecting every 10 minutes

Hi all,
Been reasonably happy with the z3 so far but I'm having problems with Bluetooth connectivity, specifically in my car. I'm used to an iphone, which works flawlessly, but the z3 only seems to be able retain a connection for 10 mins before slowly reconnecting. It's become frustrating as it restarts some of my tasker profiles(?).
Has anyone else had similar issues? Are there any known fixes for this?
I've tried turning off stamina, wifi, bluetooth timeout, display timeout, re-pairing my device - nothing has helped!
Cheers,
Russ

The normal Stamina mode (not ultra) won't disconnect any connection just limit background process.
This can be bug in firmware So try to repair it by PC companion
+ and a question; is this happen with another bluetooth devices or just with car?
cause if it happen with car it can be software compatibility & ...

Thanks for the reply. I thought I would update.
I did try checking for firmware updates but I found a different solution shortly after. I downloaded the 'Xperia Z1 Bluetooth Fix' from the google play store, installed it and selected the Tune2Air device (when it was in range). Since then I've had no reconnecting problems! I have no idea what the app has done but it has completely solved the issues I was having. I suggest giving it a go if you are having similar symptoms. :good:

I get this all the time, constant every couple of seconds when connected to my Mercedes Comand unit..
I will download this app and test it out, hopefully it sorts it.

I have Volvo V40 and when I step in my car with my bluetooth on, I see on my Z3 Bluetooth connect and then disconnect. This repeats all the time. When I then disable bluetooth and enable, the problem is gone. I don't know for sure, but what I have see on my car's phone menu, although I get these disconnects on my phone , the disconnects are not noticed by my car. But again, I didn't look into that yet. Do you have similar problems?

Hi all,
Great to know im not crazy bcuz im having the same issues in my toyota as the volvo. My phone automatically tries to pair & sometimes this works flawlessly, yet other times it connects, stalls, then spends an age tring to reconnect & all the while the cars head unit still perceives a connection. What i hav noticed is that i get great connections (fast & from where i left off) when i pause before switching off my car. If i dont pause then i need to manually connect even if the phone says its pairing with my car. Iv come from a nokia n8 which worked flawlessly however i could not control the volume from the phone which i can do from the z3 & i was wondering if the problem could be with either the phone or stereo having conflicting memory of what was last played, volume level , etc. As there must be data stored somewhere on either or both devices.

Look at this page for an explanation of Sony, seems to be a problem from the bluetooth version of the car:
https://talk.sonymobile.com/t5/Xper...s-connecting-disconnecting/td-p/853609/page/2

I dont think its necessarily the car as the problem i outlined is resolved if i pause the playing music before cutting power. I should correct an earlier comment. My problem is with playing music from my phones harddrive via a player such as the native music player, vlc music player, music visualiser, etc rather than streaming music so im not sure what peolpe using cloud services or internet radio can do.
Does anyone know why pausing the music before leaving the car is necessary when in my experience using bluetooth 3.0 didnt require this?

Idol 3 Bluetooth + Wifi while driving or changing Wifi

While driving bluetooth stops or some time lag voice if wifi is on. same issue noticed without wifi enable also but very less.
It seems whenever wifi changes to different network or connects or disconnects bluetooth is loosing or lagging voice.
Where as if i put it on speaker i can hear sound from speaker. I tried 5-6 different bluetooth and having same issue. i got replacement of phone also but same issue with new phone also. I could verify with older phone and it seems issue is only with Idol 3. Is any one else facing similar issue?

I tested this using a Bluetooth headset, and I am unable to replicate it. Turning WiFi on and off has no noticeable effect on playback via a the Bluetooth headset. Unfortunately , I have no way to test this while driving .

This issue is mainly happening while driving. It seems like while driving phone tries to goes from LTE to different modes and same with wifi as it tries to connect to different wifi. In this process it starts to lags voice on bluetooth and in few cases sound get disconnected.

Are you listening to music on your phone or streaming?
I haven't had any issues while driving using both Google music and slacker. Those are the only two streaming apps i use tho. I leave my Wi-Fi on all day. My deck is a Bluetooth pioneer unit, though the model number escapes me at the moment. I'm on T-Mobile BTW.

I don't drive anymore but I stream Rhapsody overnight onto my BT speakers and it never has conked out on me yet. There was one time I did lose the BT connection to the speakers before I did the factory reset but no issues with the BT since.

Issue is not with listenting music, it is during call through bluetooth while driving and having wifi and bluetooth both on.

OK I'll test that later on today. How often/with what frequency does it happen to you?

Almost 2 out of 3 attempts i am having this issue. even now in home i started call on bluetooth when wifi was off, then just put wifi one during call and voice from bluetooth started to get blurry and then other party could not hear me. and i had to disable wifi and then disable bluetooth and then on bluetooth again in phone.
Seems like issue is happening when phone is trying to connect to wifi and call is on bluetooth...

airplane mode on, wifi and blutooth on, LG HBS700 oem + netflix = audio lag. firmware update did not help. not ready to switch from s4 just too many quirks.

I do not have Netflix - but I tested with HBO Go - and YouTube - with airplane mode , WiFi and Bluetooth - And I am not seeing any audio lag - or audio interruption when switching from speakers to Bluetooth mid session. I am using Arctic P253BT headphones.

Alright I did a call today. It was only 5 minutes long but didn't notice anything. I'll try doing what you did starting a call in my driveway and turn WiFi on/off repeatedly at various time intervals.

I got replacement, but i can still see the issue with new phone also...

Sorry, my testing is put on hold as I had to send the device in to get a new screen (cracked). I couldn't get it done before because my wife kept stealing my car

I'm having kinda' the same problem. The thing is everytime I connect/disconnect there's a general lag in the phone! after one minute or so, it starts working ok

It's possible the bluetooth is unreliable because the phone gets busy as you indicated...I posted a couple of apps in the idol 3 apps section that help reduce lag and may help this...
Something I've done has made my bluetooth totally unreliable....whether linked to car or home phone system I can answer...talk for a few seconds and then it transfers the call back to the cell instead of the bluetooth device. I'll have to go back through my backups and find a version that doesn't do this.

I have demonstrated the same effect with my bt device (lg). When switching wifi networks bt microphone stop receiving so other party cannot hear me and the audio begins to break up and lag. I can switch off bt then back on and am fine till next wifi switchover. I was hoping the update from Alcatel would address this, was not the case. ;(

I also had the same kind of issue while listening music in car using Bluetooth, strangely it is happening when the WiFi try to connect to open WiFi available. And when that open WiFi is not able give internet accesses, then the phone just get stuck for some time. I have these issues frequently I need to restart my phone

I just purchase Alcatel Onetouch Idol 3 and and am having similar problem. I had a Plantronics M50 connected and people complained that I was breaking up and they couldn't hear me and it happened on my end sometimes too. When I'm calling someone, the ring will be normal at the beginning of the ring and then it will fad out at the end of the ring. Store rep told me this was normal. Has never done it with any of my other phones. Bought another bluetooth to try to determine if it was the bluetooth or the phone. Bought the Plantronics E50 and the same thing happens. Alcatel says it's the bluetooth and Plantronics says it's the phone. Betty at Alcatel also says the Plantronics bluetooth are not compatible with the Alcatel, however, the store sells the Plantronics Marque II to use with the Alcatel. Anyone have any suggestions or having the same problem?

I'm having the problem in car on bluetooth where the caller sounds like they are underwater and garbled and I'm told I do too. It comes and goes, very frustrating. I tested another Android and no problem.

There's a problem with the phone. It happened after the last Android update. My bluetooth was fine until marshmallow. It's so bad I went back to my Galaxy S4. I loved the Idol for just about everything, but horrible bluetooth. People can't hear you, it's a deal breaker.

Issues with Stable Bluetooth Connection in Car

I'm having an issue with my bluetooth holding a connection with my 2013 Honda Civic LX. When listening to music through any music playing app, the connection always stays steady. When there is no music running from the phone, I'll frequently get a message from the display on the dash that the phone has been disconnected. The phone will usually reconnect in a second or two, with another display indicating that it has been connected. This will happen at least two times during my commute to work (25 minutes), oftentimes as many as five times. When I am actively in a phone call, the disconnects seem to be more frequent. It has a timer on the display that shows how long the phone call has been active through the car, and it rarely gets above 3 minutes before the call gets routed back to the phone's speakers while the bluetooth reconnects. The strange thing is that my wife's LG G4, also AT&T, has absolutely no connection issues at any time. I switched phones with her for a week just to confirm since I'm the one generally driving this car, and I didn't have the car drop the connection to the phone even once. Before that week, her phone would have occasionally been used when we were both in the car and she wanted to listen to music through her phone, so it had been connected to the car for more than a week.
I factory reset the phone just to see if there was a strange software issue causing the problem. After the factory reset, the phone and car had a steady connection with no drops for about a week. When the problem came back and was obviously just as bad as before, I tried another factory reset. Once again, the connection stayed steady for about a week before I would get disconnects again. At this point, I contacted AT&T, who replaced my phone thinking that it could be a hardware issue. A week after getting my replacement, the issue popped up once again.
Besides factory resetting, which is the only thing I've found to fix it at least temporarily, I have tried a few different troubleshooting steps. I have cleared cache using the storage screen in the settings menu. I've deleted the phone from the car's connection list. I've re-paired the phone to the car without giving permission for contacts or messages. Also tried to just do a simple reboot of the phone, as well as turning bluetooth off and back on. None of these have any effect on the connection issues once they start coming up.
I can take the car to Honda, but judging on the fact that my wife's phone works just fine in the car, I'm convinced that it is somehow an issue with the software on my phone. My phone is not rooted, and is currently running Android 5.1, S/W H81010o, Build LMY47D.

My guess is hardware problem. My G4 seems to do the same thing with my Jaybird X2 headphones. I've had Jaybird swap them and I'm having the same exact issue of disconnect as with the previous set. I doubt I'd get two bad sets, so its gotta be something hardware related. Sorry I wasn't any extra help. I'm just searching to see if anyone else is having my issue.

My hunch would be whatever the BT protocol is that's being used to pair the devices. Or possibly just an isolated hardware incompatibility. I'm on my second G4 (totally separate reason from BT), and neither has had issues with pairing or staying paired. Even if I were to pause or altogether stop playback of audio, the connection remains stable for me. I pair mine with a Sony BT speaker, a Kinovo receiver for streaming to my car stereo, and even a receiver attached to my Yamaha A/V receiver at home. No issues whatsoever.
For what it's worth: I use PowerAmp Pro when I stream, almost exclusively.

The strange thing for me is that my wife's LG G4 (now 6 months old) works fine in my car under the same circumstances, but I've had 2 LG G4's of my own that essentially showed the exact same symptoms almost immediately. I'm leaning far more towards it being software, with whatever glitch not being present immediately after I factory reset but shows up within a week on my Google profile. My guess is that it's related to the phone related data transferred to the car since it stays connected just fine during media playback but disconnects soon after the media stops, but I can only block contacts to test that theory.

Bluetooth Issue

Hi Folks,
Anyone had any similar problems? When my Z5 is connected to my VW Golf it constantly disconnects and reconnects, tried rebooting the phone, un-pairing and re-pairing still no joy
Just wondered if it was a bug sony needed to be aware, it's as if it's a power save feature that turns it off and on?
Cheers in advance.

Mine stays connected to my van fine

I use one of these in my car -> http://www.amazon.com/SoundBot-Bluetooth-Hands-Free-Wireless-Streaming/dp/B00RH29CJO
No problem so far, it stays connected

I´we got the same problem with my Z5 and Pebble Time

I also have bluetooth streaming issues. Connections initiated by the phone seem to work fine. Those initiated by the car do not. Have zero issues with a Nexus 5. I believe the issue may be related to the "Throw" service.

My Z5 only connects to my Nissan Qashqai 50% of the time. My previous HTC M8 would connect every single time, but Z5 has to have bluetooth turned on/off to work with the car. It's incredibly annoying and I hope it can be improved with software

Sony will probably have to fix it in next update...

I have the same issue with a garmin watch but only since the update I had yesterday, same with the car stereo again since yesterday
Sent from my Sony Z5 ooossshhhh

Tried disabling the "throw" function and it's still doing the same.... really annoying !!!
Hope Sony are reading...

My Bluetooth keeps my device awake, which renders my Android Wear kinda useless

I have a 2014 mini and the Bluetooth doesn't have any connectivity issues, but I definitely have bugs with music skipping, especially if I have maps open or something. Better than the initial 5.0 Bluetooth bugs but still really annoying. Probably my main gripe with this phone so far other than the fingerprint scanner

I have exactly the same issue as the OP with my garmin watch it connects then disconnects every 5min or so, whats weird is if i unpair and repair the connection is good for about 3hrs then starts playing up...
I also have a nexus 6 which i've tested with lollipop 5.1.1 and marshmallow and it works perfectly, my HTC M8 i used to have did exactly the same issue's as this sony, its got something to do with the trusted device settings i think the nexus doesn't ever ask about trusted devices both the HTC and this Sony do so it can't be just coincidence...
Is there anyway to disable the trusted setup on the device ? Garmin are saying to connect via there garmin connect app and don't actually connect with the phones bluetooth directly, i've tried that still doesn't work properly... frustrating...

I also have the same problem in my BMW.
Additionally, when I start call using built-in handsfree it suddenly switches to the phone's speaker then after 10 second back to handsfree.
Hope Sony fix this soon.

Does anyone know if its possible to install a apk or whatever it needs to be so that you get rid of whatever modifications sony have done to the bluetooth process the only reason i ask is i know through my nexus 6 that the bluetooth works perfect from google so replacing the Sony setup with the pure google setup should cure the bluetooth issue's or if there is anyway to disable the trusted devices issue that i'm sure is causing my bluetooth problems this is annoying me enough to consider getting rid of this phone... Excuse me ignorance i'm not clever enough to understand if this is an impossible task...

Don't know if this will work for others but last night i unpaired everything bluetooth on my phone switched the bluetooth off restarted my phone switched the bluetooth on and re-paired and now the 2 things i had issue with are working flawlessly since about 6pm last night... ???

Similar issue with pebble time, every so often it disconnects. My only doubt is which of the two is failing the pebble or the phone.
No problem with car in-calls or audio bluetooth.

I have a Z5 and I have pretty much the same issue with a 2010 Jag XF, phone connects via BT for a differing period of time then disconnects, sometimes reconnecting sometime not.
I've not had this happen during a call, and not with other Sony Xperia Z's I've owned.
Also I don't appear to have this with other items connected Via BT.

'I aslo have problems with the BT. The z5 will pair with my garmin edge 520, after that it can't find it no more and can't connect.
With my Stereo amplifyer, NAD D3020 it can connect as it does not require pairing but the connection is poor and i get alot of artifacts when i play music over it.
For the Edge 520 it stops everytime it ask for Trusted device.
My phone is in for warrenty repair, Was for a cracked rear glass, but i told them about the problems with the BT too. The phone is on it's way back now. Hope this will fix the issue. If the BT don't work, the Z5 won't be usefull for what i want to do with it.

I know with my garmin, garmin told me not to connect with the phone directly just the connect app, weirdly my watch has been working perfect for about 3 days and now this afternoon is playing up again I've installed nothing new or changed any settings baffling
Sent from my Sony Z5 ooossshhhh

Similar problem here with my Android Wear and my Cartio Strip. Continuosly disconnect, B icon on status bar disappear, then re-appear after 1 - 2 min.
Someone known how to disable throw?
Thanks

CM13 (STOCK) - Bluetooth Failed dial up connection & reboot problem

Hi all,
Recently upgraded to Cyanogen 13 (marshmallow) on one plus one and since update Bluetooth connection to car head unit is not stable. I can receive calls fine but if I try to make calls the phone reboots. Happens less if original one plus flip cover is open (sensor not blocked), didn't happen in 12.1 (Lollipop).
Have done the forget and re-pair on both car head unit and one plus, clear cash/data and have done factory reset, nothing works.
Seems to be worse when playing podcasts via BT, not an App problem as all was fine before update.
Have looked through previous posts on a lot of forums, looks like this is not restricted to just oneplus and may be a marshmallow issue. Anyone else experience this and come up with a fix?
Cheers.

I have connection issue too in car, connects for 2 seconds then drops, cannot hold the connection. It worked before I upgraded to COS13. Only thing I've seen is report the bug to developers and hope they come out with a fix..
jira.cyanogenmod.org/browse/BACON-4733

Same for me. Buetooth connection in CM13 is very bad. Phone reboots... Worked fine in CM12.x.

Same for me, the phone reboots if any call is made through Bluetooth & Car when the flip cover is closed. Looks like a bug is reported in jira, but closed with description as invalid.
Anyone knows workaround?

There is a small magnet about 45mm up and 10 mm in from the bottom left corner of the case, (looked at when the case is open) this interacts with a hall effect device. What I did was tape a piece of mu metal 10mm x 40mm over the magnet in the cover so that the phone doesn't turn the screen off or on when the cover is opened. It needed a bit of experimenting as the first time I tried it, enough magnetism leaked after 30 mins to activate the sensor.

Ran into this on my Samsung S3 running CM13. (Seems to be a core CM13 issue....) Only a problem on my phone when connecting to headphones and speakerphones that have BOTH media AND phone profiles.
The workaround (not great, but better than a rebooting phone) is to disable one of the two profiles in the device-specific Bluetooth settings. Then it only accepts/makes calls -or- plays music/audio.
