Bluetooth connection difficulties? - Redmi Note 9 Questions & Answers

Hiya,
I've been using my RN9 with Bluetooth in my Citroen fine for the past few weeks - good stable connection switching between audio and calls just fine, but was driving my wife's Renault yesterday and it kept losing connection time and again. After I pulled over and disconnected Bluetooth to hold the call with the handset, then afterward reconnected and drove on things settled and the link was stable for the remaining 20 mins of the journey. I had a bit of difficulty getting it to maintain a connection a few weeks back but thought it was a one off
I never saw this problem with my Pocophone F1, my Moto g5 or previous phones
Has anyone else noticed any Bluetooth problems?
I wouldn't be amazed if it was the Renault's Bluetooth - it's a bit clunky, but as I say, it hasn't been so problematic before

A2DP Bluetooth Audio interrupts

Hi Guys,
i have this problem for a long time and didn't find anything about it in web or in xda forums.
I have a HTC Dream + HBH-IS 800 Sony Ericsson Headset.
When i listen to music via A2DP the connection is not very stable...
the connection interrupts very often for about 2 or 3 seconds, then works for about 3 seconds.
This only happens when i am outside, not in buildings. I this the reason is because of interferences. The connection gets better when i move the G1 into a specific orientation (upper side up) and don't turn my head to the right
On my old Windows mobile phone i played around with bitpool (=ratio between quality and connection stability by constant bitrate) settings... is there a possibility to get the connection more stable, when playing around with this setting?!
How can this setting be changed on android?
Further information:
-ROM Cyanogen 4.2.5 but same problem on stock ROM
-HTC Dream has been replaced one by a new device -> same problem
-Headset was never exchanged, but worked perfectly on my old Touch Pro with WM 6.1
Thanks for your help
There is a known issue on the Bluetooth stack and is suppose to be fixed in the Elclair 2.0 fix, the temporary work around is to first pair and connect then disconnect and reconnect it again i'm having to do that several times a day when i use my RocketFish bluetooth stereo headset. Hope that helps
thanks for this workaround, will try it tomorrow and will post if it works for me too
hmm, didnt really work for me... no change after pairing disconnecting and connecting again.
i wonder why this only happens outside, not in buildings... another frequencys which interferences maybe?!
Be sure to disable wifi.
Not trying to hi-jack your thread. If you want me to open another i will. However this is a BT question as well.
my G1 is set to connect to my stereo in my car. Pioneer BT head unit. I find that i have to manually tell it to connect every time i get in the car. When i had a blackberry before it would just connect every time on its own without me doing anything once i made the initial connection.
Any ideas?
thanks.

Worked on Dell Streak A1.6
I have Dell BH200 headset as well, and I have the same exact problem its like the audio stutters but when I first connect it its more stutter than music so you can barely even understand the music until after 30secs when it starts to normal out.
ATM im runnning Stock 1.6 for G1, im going to try Cyanogenmod 6.0 tomorrow and see if anything changes.
but everyday I go back and forth with my laptop and phone since my headphones run for atleast 3-4 days.
wow, finally someone having the same problem.
and even the same description of the connection issues.
I recently bought a orange SanFran and, as the device is fairly cheap, a nokia bh-504 along with it.
The connection isnt stable even when I put it in my breast pocket.
As soon as I move my head to the right, the streaming stops. Completely.
I can easily stop the music when holding my hand in front of the right earpiece.
so i will try the disconnect / connect again "workaround", but I don't think that will help.
I paired the same headset with my gf's netbook and I could walk through the whole apartment and the signal was stable even through up to 4 walls.
so no one here knows how to tweak BT settings in android?

[Q] Nexus 6 Bluetooth issues...

I've had my Nexus 6 since Jan. 1, upgrading from an HTC One M7 GPE running 5.0 Lollipop. I experienced Bluetooth connectivity issues with the HTC One after upgrading to 5.0L from 4.4KK, and I knew they were 5.0 related, so I expected somewhat of the same when getting the N6. My problem is, even after upgrading my N6 to 5.01 and then 5.1, most of my Bluetooth issues still exist. I'm trying to figure out if they are indeed software related, or if maybe I have a defective BT radio. I'm rooted, running stock 5.1 LMY47M, with ElementalX Kernel and Nova Launcher. Here is a list of the issues I'm having with my N6 and Bluetooth:
1. Constant dropped connection to my car's bluetooth. Will connect when car is first powered on, then drops connection after about 20 seconds only to reconnect 30 seconds after that, then drop again within 30 seconds. Sometimes it will connect and stay connected for hours. This issue didn't exist with my HTC One running 4.4KK, but did happen intermittently after upgrading it to 5.0L. This issue also doesn't seem to exist when connecting my wife's N5 running 5.1 LMY47D.
2. Problem #1 also seems to exist when connecting my N6 to my Nvidia Shield Tablet running 5.0L, but not as persistent as with Car BT.
3. When my N6 does connect to my Nvidia Shield Tablet, I can send messages using joaoapps' AutoRemote over Bluetooth from my N6 to my Tablet, but not from my Tablet to my N6. Both phone and tablet are configured correctly. This one has me completely stumped and I've spent hours troubleshooting it before just giving up.
3. Audio stuttering when connected to my BT headphones. Again no issue when using said headphones with HTC One 4.4KK or wife's N5 5.1 LMY47D.
3. Bluetooth seems to turn off randomly. At first I thought it was one of my Tasker profiles, but problem still exists even after uninstalling Tasker.
4. My N6 will not connect to my BT OBDII adapter. N6 pairs with adapter, but adapter does not work with Torque or any other ODBII app. HTC One 4.4KK, wife's N5 5.1 LMY47D, and my Nvidia Shield tablet running 5.0L all connect with no issue.
I have tried every suggestion on threads (Reboot, clear Bluetooth Share cache, clear Bluetooth Share Data, forget all connections and re-pair, Bluetooth Auto Connect app) with no luck. I love my N6, but I've hated these BT issues since day one and I've crossed my fingers with every Lollipop update that they would be resolved, to no avail. I'm wondering if anyone (or everyone) is experiencing similar issues with BT, or is it just my N6, and I should return it for a new one before warranty expires. Thanks.
I only use my N6 Bluetooth with my car (ford sync) and occasionally my home phone. I haven't had any issues. Use it everyday on my commute to and from work.
Since you're experiencing this with multiple devices id assume its you phone too. Maybe contact google for warranty replacement?
Are you by any chance wearing a smartwatch? I had similar problem with my OnePlus One and narrowed the problem down to my Moto 360 smartwatch connection. If I didn't have my smartwatch on while in the car, my auto connection worked fine.
Recently, I switched to a Nexus 6 and find bluetooth to be even worse with this phone. Seems as if the signal being broadcast is too weak. Headset audio will start to breakup, with a clear LOS, after just 10-12 ft. Also, just putting my phone in my pocket will case choppiness. With this phone, however, I have yet to determine whether it is my smartwatch that is causing the problems as well or not.

No, not using a smartwatch yet. Holding off on purchasing one until I can get this bluetooth mess figured out. I did another factory wipe and rolled back to 5.01, this time staying encrypted (used no force before). Seems to be a little more stable this time, although I have no way of telling if it's because of encryption or just luck. I think it's just coincidental, I don't see how encryption would have any effect either way. I applied the 5.1 update to LMY47M and so far much more stable than before. Again, I don't know why. I can say I am rather disappointed with Google and the Nexus 6. My wife's Nexus 5 is far more stable and I can't believe Google would allow a 'flagship' device to remain this buggy. I never had any of these issues with my HTC One. I traded up to the Nexus 6 for the Google experience, no bloatware, fast updates, etc., thinking that meant more stability. It seems that trading bloatware for the Nexus experience has an unexpected consequence of being a beta-tester for Google.
Bluetooth is different on the Nexus 6 for sure.

I also use Ford Sync system. For years it has been reliable and worked flawlessly. But starting with the Nexus 6, some of the common applications I use when mobile started crashing the bluetooth stack and giving the error, "Bluetooth Sharing as stopped working."
Before the Nexus 6 which is the first device I've owned with Lollipop, this never happened. The developer of the SMS texting app that is the main one affected by this, has tried everything to resolve the issue but he and I are now beginning to believe it is something baked either into the phone or lollipop, but before this device I never had any problems with bluetooth. I even went as far as to replace my HU in the car with the new pioneer that supports Android Auto, but to my chagrin, it still crashes on that head unit whenever the SMS reader trys to log off and switch back the stream to media. And unfortunately Android Auto currently does not support Pandora which is a must have for me. Pandora runs perfect on the new HU as it did on the Ford Sync as well, but the SMS reader causes BT sharing to error on both devices since the Nexus 6 and Lollipop, so there is something going on with the bluetooth stack and unfortunately no one I can find has any information about what has changed. Hoping Android Auto will soon add Pandora, but Pandora has not given any time estimation about when that will happen.

Funny that you mention that. Previously used my Nexus 6 in the car with no issues. Only thing that changed is that I started pairing with a smartwatch in addition, and now my Nexus 6 crashes a few minutes into using Spotify over bluetooth. Complete automatic reboot.
EDIT: Yep, can definitely confirm the combination of the smartwatch and bluetooth audio device kills my phone. Had no trouble without the smartwatch.
EDIT 2: Turns out Google just sucks at bluetooth. Phone can crash regardless, it's just more likely with the smartwatch.
EDIT 3: RMA'd the phone and the new one works perfectly. Turns out it wasn't the software after all, or maybe the watch update helped.
I don't know if this is the same issue or not, but....
Ever since I got my Nexus 6 I have had bluetooth issues with both my cars. One has a Pioneer headunit (2014 model, not Android Auto), the other is a 2014 Subaru Forester with stock head unit.
In both cases there are days when it works perfectly. Then there are other times when it's a nightmare.
With the Pioneer headunit, bluetooth audio will be playing for a brief period (maybe 30 seconds?) and then something will happen and the headunit will play a repeated beep (bing bing bing bing bing bing) till I turn off bluetooth on the phone, wait a minute or two and reconnect.
With the Forester's headunit, similar situation - i'll be playing audio and it will just drop out. Maybe 60 seconds later it may come back (sometimes). Same applies to telephone calls via the headunit with bluetooth.
The same 'issue' appears with both headunits with one playing a beep when it happens the other dead silence, but both dropping in and out whether it's bluetooth audio or a call.
N6 running latest firmware. Problem has existed since I got it last year. Recently unlocked and rooted, but hasn't made a difference.
I don't know if this is the same as my problem, but it is the closest thread I could find, so I'll post here.
I've had my Nexus 6 about a week. Running 5.1.1, unlocked bootloader and rooted. I've been using a bluetooth headset for phone audio and media audio. It had been working, though I have experienced some audio dropout and stuttering with media audio. I had not been able to determine if that was a bluetooth problem or an app problem, but now I am leaning towards thinking it was a bluetooth problem because of what is now happening.
Today, media audio just stopped playing through my headset. Phone audio is working. I've tried rebooting, I've tried forgetting and re-pairing, I've tried a different headset and I cannot get media audio to play over bluetooth.
I am having the same problem with Nexus6 I have tried two different Plantronics voyager bt headsets and a Motorola Sliver. Motorola said it may be a bluetooth antenna problem
Did a resit on phone and Motorola Bluetooth
I really need bluetooth connectivity so I am stuck
Only other option is either find someone to open up the phone and check the antenna or do it myself maybe replace it myself or look for another phone and use this one as a backup
What would you all suggest?
Thanks

Found another Bluetooth problem (this one involves WiFi)

Got a brand new amazing bluetooth 4.0 speaker so I've been playing the hell out of some music. I've been noticing the phone has been noticeably way slower in internet function.
I was getting extremely frustrated so I ran a test. Turned off bluetooth and ran a Speed Test. 31mbps down without bluetooth. and 4.5mbps down with bluetooth on.
The connection was also bouncing around all over the place and not stable with bluetooth.
WTF?

Bluetooth Issues...

I use BT at home daily for listening to music and netcasts. I have a couple of different BT speakers as well as the awesome Panasonic Link-to-Cell phone system for those who have dropped their home hard-wired phone lines. I also use BT constantly when I am in my car.
With my LG G2, BT connection was seamless and immediate, all the time, for years now. It connected to multiple devices as soon as I walked in the door and with my car audio as soon as I started my car.
With the N5, it always needs to be re-paired manually - especially at home where there are two devices waiting to pair with it as soon as I come home. It'll pair with the Panasonic phone, but when I select a speaker, the N5 disconnects from the Panasonic and then I have to re-pair with it. It will work once I spend a moment managing connections. In the car it often pares immediately, but sometimes not.
Another observation is that the N5's BT range is short, and it will drop if a line-of-sight gets interrupted momentarily.
In an attempt to fix, I have wiped the cache for both Bluetooth apps that come with the VZW N5 - that didn't help. Then, I wiped the system cache, also no dice. I wonder if this is carrier-dependent (I am on VZW) or something to do with older BT devices and the newer BT protocol that the N5 uses. I've read that the N4 has similar BT issues.
Overall, it's usable, but not as good as my old G2. Anyone else have these issues? Fixes??
This issue persists to this day. I can accommodate it with some manual intervention when I want to connect to my BT speakers.
Looking to get a BT 4.x speaker to see if it's just a BT version issue.
I only use Bluetooth in my car and I haven't had any issues whatsoever. Always connects as soon as I start the car and never drops the connection or anything. It syncs my contacts and everything just fine as well. I don't use Smart Lock however. Maybe try turning that off?

I think that's the case. For some reason samsung's 4.1 Bluetooth protocol is not backwards compatible. Ever since the s4 Bluetooth meta data has stopped working in my 2012 Mazda. Works fine with my N5 (nexus 5) and my LG G4. If I had to bet I think that's the issue with you. I could be wrong. Just thought I'd share.

Note 5 always works with my car, does not drop or anything but it has an unstable connection to my samsung gear circle headphones. I believe it is the 5.1.1 update, because they work with my wife's note 3 just fine and they used to work fine before the 5.1.1 update.
Did you ever resolve your issue? looks like some are successful after getting their device replaced and others are not and say the problem comes back. All seems to be related to the 5.1.1 update..
Bluetooth and Note 5, horrible combination

Thanks for writing. I found out that if I disable wifi, it connects a little better, though not as good as my wife's phone, Note 3 (my previous phone)
I tried to find ways to change the frequency it connects, but google was not helpful. Maybe some of the experts here could be helpful, I do not know.
Anyways, I tried to connect to our smart bulb yesterday. It would pair, but would never connect, wifi or not. On the other hand, the Note 3 connected to it immediately.
They keep updating the gear circle software but it is the phone fault, since gear circle is able to connect to my laptop from even another floor!
It's not the BT device... I have terrible luck with expensive purchases and my note 5 was no exception. I upgraded from a galaxy S relay (love keyboards) and about 1 month later my Bluetooth stopped working from all through my house to needing a DIRECT line of sight and max range of about 2 feet. Netflix, hulu, audible all pretty much useless with this issue.
I returned it and got a new one (not referbished) and I noticed a slight lag in key strokes. About 2 weeks go by and the bottom half of my screen is going haywire. Trying to scroll a Web page and it would click everywhere. Typing like I am now would result in 100s of extra letters I was never close to pressing. I returned it and got a referbished one and same thing... my 4th one which I'm using to type this just started doing the Bluetooth thing and I'm so mad.
It's not the Bluetooth device because I tried my old Plantronics I used for 5 years, my new Plantronics, my car, and these weird speakers that have water pumps in them and the issue was the same. I love this phone but it seems to hate me...

Quick question, do you have android 5.1.1 or 6? I still have 5.1.1 and thats when it started with the problems. It was all fine and dandy with android 5.0.
My wife has a Note 3 with 5.0 and the same headphones are just fine with it.
I have been waiting for android 6 to see if it works out.
My Note 5 upgraded itself to Android 6.0 and all my bluetooth problems are solved magically. I cannot believe how they can manage to screw up things for so many months and we have to wait for the new OS to have it solved. For Samsung Gear Circle none the less. I know I am not buying bluetooth watches or anything in case they screw up bluetooth again in an "update".

Bluetooth issue

Anyone else have an issue with Bluetooth audio cutting out every few minutes then works fine again for a few?
Yes!

Took forever to get it to pair with my Onkyo Receiver, then dropped the connection twice??
Just got my device yesterday, and I'm having issues as well. My Gear S3 keeps saying it's disconnected and will reconnect in a bit. Pretty annoying.

Annoying is putting it lightly, It seemed that my Gear S3 and the Onkyo Receiver are fighting for the BT connection??
For some reason this phone doesn't connect well with other Bluetooth devices nearby. I turned off 2 other Bluetooth devices inside the house and now the connection is good with my patio speaker.
No problems here. I always have my Gear S3 connected to the phone by BT, and often have a BT headset connected to the phone too.
I paired both my bt speakers yesterday and ran the dual audio from the phone for hours without issue.
Maybe the problem is device specific. I remember having the same issue with my note 7 and this BT adapter for my Onkyo receiver.
The only time my Gear S3 Frontier complains about being disconnected is when I'm out of range of the Note. The Note connects fine to my car ('14 BMW 535ix) and radar detector (can't have a BMW without one! :laugh, while remaining connected to my watch.
Yes, here also issues with connecting audio to car kit. Funny that I only noticed this after the first samsung oficial update.
It connects to the hands free phone, bit not to audio. Cleared Bluetooth system apps memory and cache and 8t worked again. Short time though. Problem is back again...
Now putting my hope on Samsung update.
Oh my gosh it's driving me crazy! One time BT stayed on 28 minutes. Usually it cuts off the call in 2-3 minutes!
Not sure what Note 8 types have BT issues, my N950U1 (SD), never has an issue. Maintains connection with Gear S2, always connects to car (audio and phone, Volvo XC60) and streams music and facilitates calls to wireless head buts/headphones. No hickups or disconnects whatsoever. Compared to Note 5 a huge improvement.
