[Q] Intermittent issue connecting to car via Bluetooth

I have a new Note 4 (Verizon) and a 2011 Kia Soul. Prior to the Note 4 I had a Note 2 (Verizon) that I paired with my car for the last 2 years without issue. I am able to successfully pair the Note 4 and the car and use all of the Bluetooth functions I would expect to work. The problem is, often (not 100% of the time), the next time I try to connect the phone to the car that connection fails. I then have to unpair and re-pair them to get them to connect. Neither side gives me anything useful in the way of error messages.
I'm at a loss as to how to troubleshoot this further. Is there a way to pull Bluetooth connection logs out of the phone?

I have the same issue, but worse. I have a 2011 KIA Sorento, and a Samsung Note 4. The Bluetooth connectivity is very intermittent. One minute is works and then stops. One minute it plays music fine and all of a sudden, the music will start going in and out, like a bad cellphone call and then disconnect. I try to reconnect and it won't. I've gotten in the car and it works great and the next time it works like crap! I've been on a cell call, talking through Bluetooth and it will automatically disconnect, but still shows connected. I have to switch to speakerphone to talk and then it all of a sudden reconnects back to Bluetooth. Does anyone know if this is a known Samsung issue? I saw a previous post from Dec 2014 which stated, " Apparently, the Note 4 and Edge all use the newest AVCRP 1.5, which nobody else uses yet. Nissan told me that they were told by Samsung, that in their next update, they're going to revert the phones back to AVCRP 1.3, which is the standard in the industry." Has this occurred?

I had the same kind of problems with my Galaxy S 6 on my 2013 F150 with Sync. I was only able to fix it by getting rid of the S6. The Note4 I had before (on 4.4.whatever) and the Note4 I have now (on 5.0.1) have no issues.

Anyone having BT connection issues on the Note 7?

Just got my VZW Note 7 and cannot connect anything BT. Anyone else have this issue?

It takes much longer to find devices.

I do not have issues with my Huawei watch, however, when on a call in my car immediately after activating the phone, the connection between the phone and car was slightly crackled at times...happened a dozen times over a 30 minute con call. I could tell it was not service related as it was a totally different sound than my Note 3.

Canadian variant here. No issues, paired 3 different devices. All working flawelessly

Canadian Bell. No issues so far

Sprint type here. No issues here, paired with headphones in seconds.

Mine wont fully pair with my Zen Watch 2 and won't pair at all with my Alcatel One watch. Of course it pairs perfectly with my Gear 2 watch. Pairs with several BT speakers as well.

No issues here. Rock solid with ZenWatch 1, Plantronics headset, and bargain bin Bluetooth speaker.

Ok, I figured it out! When I initially got the phone and logged in with my google account, it attempted to download all my apps and I stopped it. This morning I attempted to install android wear again and connect my zenwatch 2 and it didnt work. So, I force quit google play apps and uninstalled the updates. I rebooted and let it reinstall all the junk and update google play services. Now the zen app works as well as android wear.

No issues at all with my Verizon model

No notifications on Fenix 3 after Oero update

Every since updating my Pixel XL to Oreo*8.0, I no longer receive smart notifications on my Garmin Fenix 3 watch.
I have searched through my Pixel XL phone settings, through Garmin Connect settings, restarted my Fenix 3, re-paired my Fenix 3 to Pixel, reinstalled Garmin connect and reinstalled Fenix 3 watch software but still no SMS, call, calendar and other notifications?
They all worked perfectly prior to upgrading to 8.0, so it's something to do with the Oreo update.
All Garmin Connect app settings are set to on.
Has anyone else experienced similar issues on Oreo?

not that this is much help, but my fenix 5 works fine with the latest updates from both garmin and google

Google has a moron heading their Bluetooth department.
An actual stupid person.

Google has overnight released their September security update for the Pixel XL, which seems to have returned notifications to my Fenix 3.
Let's hope they stay.

MIUI 11.0.3 Bluetooth connection problem

Dear All,
I have bought this phone 1 week ago but I have problem with the bluetooth connectivity. When I would like to connect the phone to a bluetooth car device the pairing code request dialog not shows up and because of this the pairing fails. Do you have any solution for this? With Redmi Note 4 (MIUI 11.0.2.) the car works well. I tried it with other car devices but there was the same problem.
Thank you in advance!!!!:fingers-crossed:

Try going to Settings-Apps-Manage apps-Bluetooth and Clear data-Clear all data. It helped me for some time but now Bluetooth problems appear again and I have to do it every time after answering the call while listening to music via Bluetooth.

Hi! try changing your AVRCP version from 1.4 to 1.6 in developer options

Thanks for reply! Unfortunately it does not work! The pairing request dialog window is still not popping up...

Maybe you need te change the bluetooth notification priority to high and maybe check permisions.allow it to show on home screen etc

Thank you for everyone! I found the problem! The app of my bluetooth watch caused the problem, after uninstalling it the bluetooth works again.

I face a similar problem with skoda car infotainment.
In my case pairing is successful but on the first call connection breaks. Even if connection is broken and car's infotainment starts seeking for a Bluetooth connection Redmi note 8 thinks it is still connected and it stucks there. when connection breaks a message pops up that reads something about AVRCP not supported and redmi note not responding
A have unpair both devices many times but same thing happens again and again.
I have to point that i came from a Redmi note 6 pro, where EVERYTHING regarding bluetooth connections and multiple connections were operated just fluently. I have redmi note 8 just 2 days
On redmi note 8 are always connected an amazfit stratos and a meizu ep51 handsfree and there are some other apps installed like mifit.
Do you thing that i should start first by unistalling all apps?

i unistalled amazfit app and it seemed that was getting better but i assume that phone it cannot deal with multiple bluetooth connections. Unforunately it cannot managed android auto (wired connection) and car infotaimnet (bluetooth connection). On the first call connection drops.
I flashed a custom ROM- based on China roms- but things didnt got better. Having both redmi not 6 pro (which handles all bluetooth connections just fine- even transfering active call via bluetooth headset to the car infotainment as soon as it establishes a bluetooth connection while i am getting into the car) and Redmi note 8 on developer options i copy all setting from Redmi note 6 pro to Redm note 8 but all issues are still there.
I wonder if it can be used the bluetooth app from the Redmi note 6 pro to the redmi note 8 but i dont have the knowledge to do it

I have the same problem. It sucks that redmi note 3 which i had before worked 100% ok...

All these issues make phone quite useless considering that everyone goes wirelessly. I wonder if this disappointing case is claimable from Xiaomi.

just noticed the same problem, both of my RN8pro bluetooth mac is 00:00:46:00:00:01 which is nonsense.
maybe you all got the same mac as mine, which is generic mac.

How can I check Bluetooth mac address ? Do I think there is something can be done?

Settings > about phone > all specs > status.
There's a bluetooth mac near the bottom.

I checked my Redmi note 8. It's seems normal, 28:16:7f:b5:65:2b is it?

MIUI 11 - Android 10 version?

The only workaround i found is to keep one connected bluetooth device at a time. So before i get into my car i have to disconnect bluetooth headphones and reconnect them after. Bluetooth management of Redmi note 8 is a big mess. I assume that is a phone's hardware problem its incapability to manage two or more bluetooth connections simultaneously.
I contacted Xiaomi customer care regarding bluetooth issues and i was finally asked to perfrom a test. I wonder how a test could resolve it

In the attached screenshot in developers options the max connected audio devices option is 2 but it's deactivated so i cannot changed it eg to 3. Could it be the solution to bluetooth connectivity issues? Is there any way to activate this option and change it?

Bluetooth not working

Samsung S20 and Waze doesn't work on Android auto

Hello,
Previously I made with my Samsung S7 contact through AAwireless with android auto and that has always worked perfectly. I mainly used Waze for navigation.
Now I have a Samsung S20 but Waze doesn't work well on it. After a few minutes, Waze freezes and is no longer usable. I have connected the mobile with the cable and then it aldo does not work correct. So it's not AAWireless.
I have adjusted the battery settings as far as I can find but the problem remains. And if I install other navigation systems (TomTom/Sygic or Google maps), then I don't have the problem. So it's really in the Samsung S20 and Waze.
Does anyone have an idea what this could be?
