[WORKAROUND] EB13 Bluetooth problems

As being discussed in various threads, some people are having BT problems with EB13 based ROMs.
The Problem
Inability to connect at some future time after having paired device with phone. Rebooting doesn't help. Only solution is to unpair, and re-pair, then device will both pair and connect with phone.
Also seen by some people are audio routing problems after disconnecting BT. Not sure if this is confined to devices that support (and connect) A2DP... more investigation/testing needed.
The Workaround
I tested various conditions to see how the BT subsystem behaved under various usage modes. In particular, across boots, turning BT on and off on the phone, on the device, etc. -- and then observed if automatic connection would re-establish after each combination of conditions.
I found that the problem seems to only happen if I turn off BT on the phone. If I leave it on, pair and connect with a BT device, then I can turn the device on and off at will, and it will automatically connect.
This (normal) function persists across reboots, at least for the few I tested.
I don't know how power-hungry the BT radio is when idle and not connected. My gut feel is that it is a pretty small drain, so leaving BT on all the time as a workaround probably won't have much of an impact on battery drain. I use Juice Plotter, and have a good history with BT off to compare to. I'll post JP measurements/results tomorrow after a 24 hour cycle.
Caveats
I also changed my Epic BT device name before I explored this situation with toggling the BT radio on the phone. While the name change did not correct the problem on its own, I can't rule out that the combination of name change and leaving BT on is what is making things work, rather than just the latter alone. So, to try this workaround, you must also change your BT device name on the phone, and leave BT on. Then, clear pairing and re-pair for the target BT device.
My Request
Would people that are having this problem please try this out, and report back in this thread success/failure, and any other observations. What we see in testing these different modes will be very helpful to the devs in trying to trouble-shoot an fix this problem (which I have no doubt they will long before Samsung does).

It should be noted that some folks are having issue connecting to a device, even after un-pairing and re-pairing. If that is the case, you might try this-
http://forum.xda-developers.com/showpost.php?p=12120496&postcount=1392
Also, some folks are reporting an issue with multiple pin requests before a device will finally pair. I haven't seen that one myself, but just thought I'd mention it.
For what it's worth, other than the BT routing issue, I haven't seen any of these pairing or connection issues on my stock rfs Epic. It wasn't until I converted my other Epic to ext4 that Bluetooth had any issues, and they were all fixed by wiping data and have not returned since.

I have tried the workout around before in the past, and it changed nothing. Also I have noticed I seem to have more issues with particular audio bluetooth ear pieces, like BlueAnt Q2. It will show pairing is connected but after a couple hrs on the bluetooth connection is gone, but like I said it shows paired. My cheaper Plantronic ear pieces seem to work much better, except the fact I have to re-pair after each reboot of the Epic.

Ive tried leaving bluetooth on all the time, but after a reboot,
i have to repair ive tried all suggestions to fix it and the only way it seems is once it gets connected is always have the phone on and cant die and bluetooth always has to be on,
even after a long period of time somehow it loses the connection even if bluetooth is on and phone stays on,
There must be somethng the developers can patch with a flashable fix or another work around to get squash this annoying bug.. ill try to get a logcat today and try your method again see if i have luck

I will try to leave mine on and see what happens. Name change did not help.
But short on time. But given the chance I want to go back to bonsai 3.0.1 and see if I have the same problem. I don't recall it giving me a problem.
Edit: of I leave BT on, on the phone and just turn the BT device on/off it will not pair back up.
Edit: May have figured something out. I have been toggling BT with a widget. When I toggle from the notification bar it seems to work (so far). Which would also explain why it quite working as I added apps. As from clean install is used the notification bar and later used my power widget. But I have always used a widget before. I will test this out at work and see if this work around keeps working for me.

I have to re-enter the PIN after every reboot. Mildly annoying.

Having tried the various bluetooth fixes given in different posts, I am now just leaving bluetooth on as described in the workaround above. I have left it on for a couple of days now and have had no trouble whatsoever with my headsets (both regular and stereo/A2DP). They connect as they should and do not require re-pairing. Even if I reboot my phone they have been connecting back up without issue. The only thing I cannot do is manually toggle bluetooth off and back on or the devices need pairing again.
I initially was worried about battery life by leaving BT on, but so far I have not seen any major difference... is the bluetooth radio only consuming power if a device is connected?
I still hope a permanent fix can be found for this as it makes me feel like my phone is "broken" somewhat
BTW, I am running EB13 with CWM 3.0.0.6, Bonsai 3.0.1, and Emotionless Beast theme

In my experience, the BT radio does not use any power when not connected to a device. If it does, it's not noticeable in Spare Parts or in performance.

I fixed my connection problem by doing a wipe and fresh install of my current rom. Now my bt is working perfect. Just make sure not to recover your date from nandroid that may cause u to recover what ever was causing the bt problem just restore your apps only my back up or appbrain.

What rom are you running?
Also did anyone by wiping data all data, confirm that on bonsai rom fix the non connecting issue?

Have the pairing issue with ACS EB13 Frozen ROM 1.0.3/ Twilight kernel. The BT headset I use is Plantronics 975. Never had a problem with any of my phones until now... even my Treo 755 connected properly, not to mention BB Tour FWIW, my headset supports A2DP and I wiped/reflashed ROM/kernel several times without resolving the BT issue. Will leave BT on, but does it mean after every reboot I have to re-pair? That's not good if true, I hope a permanent fix can be found soon.

Update: For me at least, this workaround is still working 3 days later without a hitch, and across more reboots than I can count.
While I don't _know_ with tech/spec/engr certainty, as mentioned above it seems that BT uses negligible power when it is only listening for connection requests, and has had no discernible impact on battery drain at all.
So, this seems to be a viable workaround for the time being for some of us... it's real. What we need to work on as a community is figuring out what the critical difference is between those for which it works, and those for which it doesn't. KEEP POSTING AS MUCH DETAIL AND INFO IN THIS THREAD AS YOU CAN, EVERYONE... DATA IS WHAT WILL GET US TO THE BOTTOM OF THIS.
Personally, I think the key difference between the two groups is the size of your junk -- People with small equipment seem to be having all the failures

I've had this issue on all Froyo builds. I have tried 7 different BT headsets from Samsmsung, Plantronics, Jabra & Blue Ant, all of them a2dp compliant with the same result, after a while, they stop connecting and I have to re-pair. As for the "workaround" since I have several extended batteries I've never turned BT off, and while it does take much longer to lose pairing, it eventually stops syncing or syncs only the headset protocol but not A2dp. For myself, the only solution I've found is to go back to DI18 which, although has its faults, works flawlessly with BT

I have been trying to get my brother's Epic working properly. It is rooted with EB13 installed. If this bluetooth error is not related to what others are having, let me know and I will create a different thread. I got his motorola H520 paired. I press the button and it starts the bluetooth voice dialing. It beeps and says please speak and then immediately gives and error saying the connection to the bluetooth was lost but the settings shows it to still be conneceted and it is as you can answer calls with the bluetooth without having to reconnect it.

My plantronics backbeat is paired and for phone calls is working, but sometimes no audio through music or video players. I had to un-pair, then re-pair then audio will work for a while.
I am using CWM 3.0.0.6 with midnight ROM with its installed kernal

Happening on my Plantronics Voyager Pro+ - It seems that everytime I pick up my phone the BT disconnects and then after about 15 to 30 seconds reconnects as long as I don't push any buttons.
There is also a lag "thingy" that occurs when I'm on a call and then another person calls - while the the second call is coming in, it seems like the packets get interrupted from the handset to the headset. Then once the incomming call goes to VM, the audio from the current call gets restored. Not sure if this is helpful or not, but I wonder if there are some routines in the BT transmission that have common "hooks" which are used when a second call comes in - Hope that is not too much of a noob statement...
Is anybody else having that "laggy" issue in the same circumstances?

Temporary fix to Bluetooth issues?

So... searched pretty much a month now for a solution, so don't flame me if I missed it ..
About 2 months with OPT, and pretty much a working phone on Oxygen 2.1.2 but it is unparallel to my OPO when it comes to OS with Cyanogen, in terms of beauty and speed. Yes, my OPO with less power under the hood works better than my OPT.
Tries Exodus ROM (CM12.1) and it is the one I like, but.. my BT doing all sort of funny stuff.. It turn itself off (symbol disappears from top of the phone) at random times. Events that kill BT are a phone call, deep sleep, and probably other events.
Rebooting the phone fixes it for up to 10 minutes. But obviously I am not going to boot the phone every time I need to use BT. I have a Moto 360 , a car audio , a headset, and a radar detector in the car connecting to my phone over BT. So pretty much I need BT on and up all day long...
What I discovered is if I clear data from Bluetooth share (setting->apps->all-> Bluetooth Share) my BT comes alive for a while again, so something in CM12.1 is messing it up. Obviously , I can't clear data every 10 minutes either... Not manually, anyways..
Just think every time I am getting to the car i need to clear data to hook the phone to the car. As soon as I do, the connection will stay on until I am done driving... and then drops again when BT in the car turns of, in few minutes. Really annoying.
The main problem is the Moto 360. It became a useless smart watch without the BT on the phone. Running it on wi-fi just kills the watch's battery, so that is not an option either...
Anyone else is in the same situation, or better, found a work around ? Somehow i can't seem to find anyone else with this issue.
Thanks,
BigE

Yes I have the same BT problem on my op2 with OOS 2.1.2 in car.
Nearly unusable audio (only phone function connects), audio (if it sometime works) don't stop during incoming call, phone book is not probably synced...
Impossible to fix it on my own! Oneplus must do that.
I hope with marshmallow will something fixed.

Bluetooth keeps disconnecting

Anyone have an issue with Bluetooth disconnecting? The icon disappears from the notification Bar, then reappears when connected again. Happens with my car and Gear S2 watch. Very irritating!

Mine jut started disconnecting a couple days ago, right after the T Mobile update. I thought it was my bluetooth earbuds, but I happened to look at my S2 Gear watch at the same time and saw that it disconnected too, and then reconnected about 5 seconds later...

I got mine to get abck to working normal today. Came across another forum where someone suggested the following:
Head on over to Settings > Applications > Application Manager. Select More and then Show System Apps. Look for Bluetooth Share, then tap on Force Stop, and clear the cache and data.
As soon as I did this all of my issues went away and everything connected fine!

I have the same problem and it is very annoying, bluetooth keeps disconnecting from my car, specially during calls and then tries to reconnect again. This never happened to me before in any smartphone so this is a specific problem from the S7. I tried clean cache etc. but the problem continues. Anybody can recommend something else?

Have you tried un-pairing each device you use and restarting the phone, then pairing? I was having issues as well with Jaybird earbuds and my mini jambox. I did that and they seem to be working. I also followed the directions of resetting Bluetooth sharing. Been 2 days. No issues.

I've been having this issue as well - it happens when I'm not on a call and unfortunately when I am, which really sucks. Have had my car for a long time with many different phones so definitely not the car. Gonna try the bluetooth share tip from above - hopefully, that fixes it.

Yes same problem for me, never had any problem with all the other phones before. If you find a solution please share.

Just today in 5 minutes I lost connection with my car twice during a call, very annoying.

Mine went away after a factory reset and now its returned. ARGH.

I was having massive bluetooth problems that i thought was linked to the system update. I was getting random reboots, disconnects, and just all around flaky performance. I traced mine problem to the Nova launcher beta and night mode. For some reason it hated my bluetooth. Restored the stable version and removed night mode and my bluetooth is a champ now with no issues.

I think I found a solution, go to app manager -> click more (upper right) -> click reset app preferences. Didn't have any problem in last 2 days for the first time.

Didn't work for me. The whole Bluetooth stack just quits and restarts several seconds later. I have a Gear S2 watch constantly connected.

I am still facing the same issue even after i reset every thing. i think it is a software issue as this problem appeared only after the last software updates.

It happens to me when I use Google voice mic icon... it always disconnect my Bluetooth connection.

I feel your pain
I have a Jaybird Bluebuds X that I've been using for over a year now with the Nexus 6 and 7. Never a connectivity issue, and range was never an issue as well. With the S7 Edge, It keeps dropping the media connectivity whenever i'm streaming from either music or video, even when i'm standing a foot in front of it. Stays connected for phone audio only. Then drops completely after a few minutes. I've tried all the solutions posted without any success. Also does this with my bluetooth speaker. Very frustrating. Between this and no ambient display, i'm ready to go back to my Nexus 6. Big and slow, but at least it works. lol.

I have an issue in my car with bluetooth constantly connecting and reconnecting. I found that if I turn wifi off while I am in the car, my bluetooth is fine.

Bluetooth on 8.1 official.

I think the 8.1 is a great update with everything flying along. I have one little annoyance though: my Bluetooth speaker is fine playing something (which is the main thing) but after I switch it on and before I start playing anything on the phone, it keeps bleeping that it has disconnected then reconnects again a few seconds later. My smartwatch is doing the same thing: vibrating that it has disconnected then reconnects again a few seconds later. Bit annoying & never experienced this before update. Anyone got any ideas what could be causing that?

Have you tried going into Developer Mode and Changing Bluetooth versions? There are several choices!

No I haven't. I'll try that thank you. Do you know what version it was before? Worked perfectly for me. Cheers.

I'm experiencing something similar to what you're describing. When I connect my AirPods they keep on playing the connected sound, as though they're reconnecting over and over.

Well, I tried changing the Bluetooth version (AVRCP whatever that means!) and I've only tried it once this morning but so far so good and it hasn't been connecting/disconnecting at all. I changed it from 1.4 to 1.6 just by guesswork but thanks to poster who suggested that.
As I said, only day 1 but I'll report if anything changes.
On another topic, I use a Garmin sports watch which has smartphone features. It works absolutely perfectly all the time while showing up in the phone's bluetooth settings as being permanently disconnected.?

wow this fixed my BT issues!!!

Bluetooth issues after Oreo Update

So I seem to be having issues with bluetooth. Most of the BT devices work, but my TomTom Raider 400 does not seem to want to work.
I was able to pair it to the device, but thats all I get, the TomTom says it won't connect or anything, It was working great nougat now it does not work anymore. I cleared out all network settings, still no go.
Anyone having issues with devices that perhaps require data? anyone have any ideas?

I'm having similar BT problems since the update. Sometimes my car doesn't connect. Quite often my Gear S3 disconnects when the phone is still well within range. My Sat Nav will only connect via BT if I search for it. There is definitely a glitch but I haven't found a fix

Same issues here, with Tomtom GO 510 and with asus Chromebook too (via Bluetooth only)

I've updated to CRC7 today using the SD card update method described here.

I updated to Oreo 8.0 on my S8 today and have had bluetooth connectivity issues ever since. Listening to music in the car, it will randomly drop connection. Also, some track information is no longer showing on the headunit (the playback time and the overall song length). Everything worked perfect before update. Seems to have been a known problem that may have been addressed with the 8.1 update on Pixel and Nexus phones. Unfortunately my carrier (ATT) just rolled out the 8.0 update today for my S8. I'm at a loss for what to do.

It's failing left and right.
I turn it on and it turns off apprx 1 min later.
I turn it back on and it does the same thing (each time).
removing and re-setting up everything fails.
rebooting fails (same as turning on and off)
safe mode does not help.
So far, Oreo has made Bluetooth useless on my S8

After Oreo update my S8's BT became spotty working 20% of the time on calls in the car. So i searched & read that resetting network connections would do the trick. It wasn't under connections->more settings - instead i found it in about phone-at the bottom under Looking for something else-> Reset->Reset Network Settings . Yehey i found it & reset my network settings!
Now my BT won't turn ON! From 20% to 0% function!!!
What a what!
Fix this Samsung!

Same issue here. My S8+ was rock solid on Nougat, but since the update to Oreo yesterday my Bluetooth does not connect 19 out of 20 tries in my car. I factory reset my phone thinking it may have been an issue with the update process, but that did nothing to fix the issue. I really need a solution as I need to talk while in my car.

Haven't tried using Bluetooth on anything else, but my phone stays consistently connected to my Gear watch.

Anyone have any solutions to this? I'm experiencing the same issues. Won't connect consistently with my gear s2, drops certain speakers all the time, although it seems to stay connected more consistently to my car. Really frustrating and don't want to wait for the glacial pace of Verizon update rollouts.

I just installed the update, but up the thread above several people say that factory reset didn't fix this issue for them.

It won't make a difference. I factory reset my phone after the update to Oreo and reconfigured everything from scratch, no restore, and it made no difference. My Bluetooth still does not work with my car. It works with my Pebble, my Sony Bluetooth headset, and a Marley speaker with no issues. Why is it that only my car fails? It is the most important one.

I am having the same issue when listening to music with Bluetooth in my car. The music gets choppy and does not play back the way it should. I have been looking everywhere online for a fix and I haven't come up with anything. If anyone has any suggestions it would be greatly appreciated.

Same issue with Sony XAV-68BT headunit. Music plays through Bluetooth, then drops rendomly, then manually have to reconnect. Very distracting while driving. Phone calls do not seem to be affected though, so... There's another little tidbit.

Actually I did notice the other day that my Gear Sport was on standalone mode instead of Bluetooth, so I was missing texts from people. Really annoying. Samsung better address this.. going to take ages for Verizon to get the update though, I'm sure.

Any chance that the Bluetooth apk file for the Galaxy S9 would work on our phones? Maybe it would help?

I'm having similar issues here too. I was on Nougat with zero problems. Did an OTA update to Oreo and suddenly my Kenwood car stereo keeps losing bluetooth connectdion. Used ODIN to flash back to Nougat and it's rock solid. Decided to flash Oreo instead of doing it OTA, and suddenly the bluetooth is flakey again. Flashed back to Nougat, and it's rock solid. I've also tried factory resetting and reconfiguring the car stereo, did a factory reset of the Galaxy S8, cleared the cache, and nothing works. The only way of getting Bluetooth to maintain a connection to the car stereo is to be on Nougat.
Interestingly though, I have no problems with my Gear S3 maintaining a bluetooth connection.
It appears it's only some devices that have the issue. I don't hold out much hope that Samsung will fix it though. Weren't people complaining about the same thing during the betas?

I guess this can solve your problems too, I had an issue since the oreo update, cant select anything but SBC reverting to default, even with the level u app not showing UHQ, I started a chat with samsungs members app and they told me that is an error in the update, not all devices are presenting this problem. well, the solution: 1. back up your data with smartswitch app(I backed up with a sd card, 10Gb info) if you have whatsapp do a chat backup because they dont backup with smartswitch. 2. delete your samsung and google account. 3. Do a hard reset(witch the phone powered off press volume+, bixby and power, until you see the recovery menu), wiping cache and then wipe data/factory reset(move trough the menu with volume+- and select with power). 4. start the phone and add your google and samsung account, then restore your data with smarwitch app. this will let you select the BT codec again.
worked for me and the bluetooth conection is more stable
