Bluetooth Connectivity With My Car

After searching this forum there is no thread on Bluetooth issues connectivity.
For a wile now i been searching the net and different sites for a fix between my phone and my car bluetooth. Before the epic i had a windows phone and the connectivity was fine including all the phonebook would load up and everything the system was build to do. With Android Epic i been having issues. Sometimes I cant connect to the car and other I am able to connect but phonebook wont load.
With all the Geniuses in the website i am sure someone can come up with a fix.
I figured i open this thread hoping we can find a final fix to retire this problem.
If it helps I am running the latest Viper Rom with Genocide kernel at 1.2ghz
However the rom did not change the statues of my issue.
Any help would be appreciated.
Thanks

I also have connectivity issues with bluetooth, in my case the car has A2DP allowing for music to be played over the car's stereo. It cuts out so much that it is completely useless for music. I mostly listen to podcasts but Pandora would be nice. However it cuts out so much that it isn't worth it. So if anyone does have a solution. To me though I've tried so many kernels, and roms to no avail that I'm pretty sure taht the software Samsung has shipped has faulty drivers. By the way it also seems that the cut outs occur when switching towers, however I could be wrong.

I use this in my car: http://us.kensington.com/html/14484.html
It may cut out every 45 seconds or so but it's the only thing I've used. Got it on sale for $20.

I've got a pair of a2dp bluetooth headphones that I use to listen to podcasts via my Epic. I've had zero problems with those (using DK28 atm, for the record). So I don't think there's a hardware problem with the Epic's bluetooth.
If we're going to get some troubleshooting done, we should get a bunch of details from everyone. Like exactly what bluetooth hardware they're using, and what roms they're running.

Does everything cut out, or just Pandora? If it's just Pandora and other apps that need data connection, it might not be a bluetooth problem as much as a data connection problem.
I would suggest testing it by trying the car bluetooth with something that requires no data connection at all, like pre-downloaded podcasts.

I am talking about connectivity issues with in stock car bluetooths.
this problem is big many people been having this issue and there is a list of stock bluetooth cars that android wont pair with. I had the touch pro 2 for sprint with windows system and it worked fine in my car bought the epic and there we go. Now looks kind of bad that i would need to get an aftermarket piece to listen to bluetooth calls and load up the phonebook from android to my car.
Windows got it right even though i would never go back to a windows phone so i know there is something that android messed up here
Below i will put some links to show you how there is A LOT of people that been having this issue.

I have a 2006 Dodge Durango. It has Bluetooth. My old phone, a Samsung flip phone would connect without issue. My new phone, a Samsung Captivate, will connect most of the time, but often times, once it connects, it drops the call.
I understand this is an Epic thread, but I thought I would add my input as I am having similar problems (and this came up on my search).

If I understand you correctly, you connect some of the time and sometimes not.
Regardless, if your phone is rooted you might wanna try this.
I had a lot of issues with my bluetooth after upgrading to froyo and tried a lot of fixes including wipe3x and odin to stock....this is the one that worked for me.

Ensure that you first
- delete the car from your phone,
- delete the phone from your car,
- disable bluetooth,
- delete the file,
- CHANGE YOUR BLUETOOTH DEVICE name,
- restart,
- reenable bluetooth
- re-pair your phone with the car.

Bluetooth cuts in and out when connected to 2 devices (car's "phone" and "media")

Bluetooth cuts in and out when connected to 2 devices (car's "phone" and "media")
I have a GSM Galaxy Nexus on stock Jellybean, and bluetooth streaming works great in my car (Chevy Sonic) until I also connect the "phone" connection. When it's connected, the music cuts in and out constantly. Phone calls seem to do the same thing if "media" is connected.
If I kill 1 connection, the other works great. Is this a Galaxy Nexus problem or Jellybean? I've tried stock, franco's, trinity, etc kernels but I'm guessing this won't matter (since the source was JUST released for JB).
Does anyone else pair to multiple BT devices simultaneously? Do you have issues?
I just came from an iPhone 4S, and it paired nicely with both connections without them cutting out. I hope this is something I can get working because I use both functions all the time.
Thanks!

I connect to 2 devices in my truck and it actually seems to work better since installing Jelly Bean. On ICS I had a similar problem. My truck connects via the "phone" profile and I connect to a bluetooth adapter for the "media" profile. I could use either of them independently without a problem, but with both connected, my call quality was awful and my music would cut out periodically. I believe that the truck "phone" profile was disconnecting and reconnecting every couple minutes as I would see the display on my truck indicate that a bluetooth device had just connected.
Since installing JB, that behavior seems to have stopped. I can't say for sure as I haven't driven very much yet since installing it, but early testing seems to indicate the problem has gone away. I know this doesn't help in your situation, but I did want to share my experience as it was similar to yours.

Bluetooth auto connect issues - Chrysler UConnect

I have a new Fire Phone running the stock Fire OS 4.6.1, rooted and with Google Play Store Installed.
My vehicle is a 2007 Chrysler Town & Country with the UConnect feature built in. I have successfully paired my phone already.
The main issue is that I have to manually connect every time I get in the car. After I leave the car or the car is turned off, it disconnects as expected, just never reconnects automatically.
I just switched over from an iPhone 4 and this is a major inconvenience. WIth the iPhone it just worked. If I was on a call and got in the car, it would automatically switch over to bluetooth UConnect and come over the cars audio system.
Is there anyway to make this work properly? I have seen a couple apps in the Play Store that seem to state they can fix this, but I am a little weary of them. Like Bluetooth Auto Connect
Does anyone have any experience with this app or have any other general advice on this? Thanks in advance for any suggestions.
I did also check this thread with no real luck http://forum.xda-developers.com/showthread.php?t=1312576

Does your car have multiple ways to connect a device to the car's stereo via Bluetooth? According to this post, using the steering wheel/voice commands makes a difference versus using the stereo's dials.

Car Bluetooth issues (Mazda)

My Pixel XL is having a hard time connecting to my car's Bluetooth (Mazda 3). I had no problem pairing, but connecting seems to be hit or miss. Once it connects, things seem to work fine. Any advice?

My advice is get used to it. Not being mean saying that, its just that Android bluetooth has been hit or miss for a long long time now. Some will work well with some devices and some will not. And it will change every once in awhile after an update.
Toss a Bluetooth toggle on your home screen

If you're not on the latest security update, I'd suggest that you install it. Older GM vehicles had an issue connecting to BlueTooth. It was resolved with the December 7.1.1 update.

Yes, I am currently on 7.1.1.

Is there an official Google PixelXL forum where I can voice my concerns so that Google/Pixel people come in contact with my grievances in a more direct manner?
Thank you!

I think I've noticed a pattern that might be relevant for this issue: After rebooting, connection happens pretty much instantly. It gets gradually slower everytime i connect afterwards, until the A2DP profile stops connecting altogether, after the 4rd or 5th connection attempt. Rebooting the Pixel resets this cycle.
Interestingly, these connection issues happen only with my Mazda car. No other BT devices have problems connecting to the PixelXL, which makes me think that this might be a Mazda issue rather than a Pixel issue. But then again, I had no such problems when connecting my Mazda to my Galaxy S6. Not sure what to think.

Bluetooth always reconnecting in car

The problem is to connect Bluetooth on a Moto Z Play Android 7.1.1 patchlevel 2/2018 (current in reteu, was same result with Android 6.0.1 12/2016) with a Volvo XC40 car.
The first pairing with Bluetooth succeeds for a second. Then, nearly immediately, both displays (car and mobile) show reconnecting for about 10 seconds. It has a connect for a fraction of a second, and then is reconnecting and so on.
Trying flight mode and then only Bluetooth enabled on the mobile did not help. IIRC it showed some message about "My Volvo Carnull not bonded" (the name of the car for Bluetooth is "My Volvo Car" and some message with typo, something like "conecnting not successful". After that I rebooted, result was the state before with reconnecting.
Did try this several times. Also did try to reduce the amount of Bluetooth access types the car tries. There are 4 connected: phone, audio, internet, contacts. Did also not help.
Has anyone an idea how to get a successful connection or what the cause of the problem is? Did search for similar problems with Bluetooth in cars, but could not find anything (except for that hint with flight mode which did not help).

What I tried by now:
- Flight mode, only Bluetooth (as already mentioned). No change
- Remove all bluetooth connections. Pair new. No change
- Delete data for sytem app "Bluetooth Freigabe". No change
All other bluetooth connections are working fine. Another Moto Z Play using Android 7.0 (01/2017) is working flawlessly with that car. Strange for me is that it didn't work on 6.0.1 in the same way it does now fail on 7.1.1, but the other Moto Z Play using 7.0 is connecting stable.
Still the question: Does anyone have an idea how to get the connection working?

Factory reset?
I see that you deleted all bt connection but do you have some apps that are using bt? Like for smartwatch, headphones...?
I have Amazfit and watch must be connected to be able to pair a new device. Drow me crazy first time when I had that problem. I thought that car audio is broken, then phone... After pairing, watch doesn't have to be connected to reconnect.

I was afraid this reply could come. When doing a factory reset, I do following: Pack /data/media somewhere because Nandroid omits this. Backup all partitions using twrp. Backup all apk using adb. Export SMS. Export contacts. Screenshots of the launcher screens. All this takes about 2-3 hours. Then I struggle a week until my device behaves like before. I'd be willing to do it if I saw a reason why it could help.

Headphone, yes, there is August EP650 configuration tool that is not necessary. Thank you for the hint, will try it. Also I read somewhere it may help to delete cache partition, that's also worth a try before doing factory reset. Maybe I'll wait for Oreo before trying factory reset, could be they fixed some bug there.
Edit: BatOn which shows Bluetooth battery for external devices could also be the culprit.

That's a strange behavior indeed. Amazfit seems to do something wrong.

It doesn't get any better if you upgrade to Oreo, I've been having problems with my Moto Z play disconnecting and reconnecting to the radio in my Corolla constantly ever since I went up to nougat. To be honest I just bought a good pair of headphones and stopped using the radio. Good luck though, if someone finds something that helps let me know.

I'm using bt with car audio, headphones, smartwatch... No problems at all, except one with Amazfit. And that is related to their bt implementation, not Moto fault.

Seems the last action to remove Bluetooth related apps was the right one . There were two apps installed:
1. BatOn showing the state of battery of connected Bluetooth device
2. August configuration app for August EP650 headset
Removed both as they are usually not needed and it seems to work now. Will see later if it only worked for the short test I did today (currently I try to avoid driving because of an injury) or if it keeps stable.

Good, you didn't have to factory reset after all
