Bluetooth connection dropping

I've noticed in my xe r sport that when I get in and start the engine the Bluetooth connects fine, however shortly after seems to drop connection before randomly coming back.

It's then fine for the duration of the journey

Any ideas? Using a oneplus 3

Sadly, my Sony Xperia XZ hasn't benefited from the latest firmware update (still on 7.1.1). I hope the latest android firmware is the answer for me also. It's becoming highly annoying when the Bluetooth drop outs. Currently I can get through about 3 mins of a Spotify track before the music cuts out and radio kicks in. May have to resort to music sharing from my IPad for now (that works perfectly).

I have a similar experience..Everything was working fine. Took car in to the dealers for an ad blue top up. I am not sure if they applied any other fix. I don't think they did, however since then the blue tooth seems to be dropping . A few times, the phone didn't connect to the car at all, and i had to re pair the phone twice since then. One time, i couldn't hear my music through the car speakers. the display showed the song was playing, but no sound . Clicking the little speaker icon on the corner made no difference. it fixed it self the next time i started the car. Strange, since i had absolutely no problem, and then all of a sudden bluetooth connection issues started.

Hi all,

Well, it can't be just the phone's compatibility. I use an Xperia XZ with version 7.1.1. It worked fine with my XE 180d until I had my car in for inspection. After that the same error as described here occurred permanently. Jaguar told me it's been verified with version 7.1.1 (41.2.A.7.35), but not with 7.1.1 (41.2.A.7.65) which is my version, and it doesn't matter if it worked with it before. That's something you have to be care of when they update the Jaguar software.

I'm pretty desperate because of their service and the current situation. What to do now? Upgrade to 8.0? And then they're gonna tell me, well, the XE is not tested with this version, too... and so on and so on. But when you come to the dealer, first thing they do, they ask you whether you have the latest version of Android installed on you phone... I don't need to continue, do I?

Have a nice weekend

I had to revert back to an iPhone as I spoke to the android manufacturer who acknowledged the bug but could not confirm when it would be fixed. Spoke to 3 who agreed to change phone to iPhone at no cost. Since then I have had no dropouts at all.

I have had this problem for the last year and a half. This has been a problem with my Pixel 2 from the moment I bought it. I also had problems with my old HTC phone once it upgraded to Android 8.0 (perfect when it was 7.x). Google must have broken the Bluetooth stack at least how it is related to pairing with my Jaguar XE 2017. I researched this extensively including changing AVRCP to different versions etc. I also took it to the dealership and had new software downloaded to my XE. Nothing really helped.

The symptom would be that the phone would initially pair then drop after a minute or so (right after I get on a important call etc.). Then it would generally cycle several times and usually after about 5 or more minutes of this, it would finally establish a stable connection, until i stopped the car and then the whole awful process would repeat. It made it really unusable. I am not a fan of apple so refused to get an iphone (which everyone said worked fine).

I am now happy to say the problem was just fixed. I went into my Pixel 2 to system->Advanced->System update->check for update to get the "MOST CURRENT VERSION". I had to keep doing this as my phone kept installing new updates (I guess they have to be applied in a certain order). You do it until the phone shows "Your system is up to date" and their are no other updates available. It took a while as my phone installed 9.0 and I guess additional security patches. It now is on version 9 Security Patch March 5th, 2019. I am happy to say it now works flawlessly. Pairs perfectly etc. Looks like google finally fixed their bug. I hope this helps the poor people that have been living this nightmare.

Just upgraded to the Samsung S10+. Previously had the S8+ with zero connection problems.

The S10 keeps dropping connection. Does this for about 3 cycles then becomes stable.

Madness :evil:

Hi,
I have a Samsung S9, updated to pie and it keeps dropping the connection to the car. It is does this in our other car as well, so not a Jaguar problem. I thought I'd solved it by uninstalling SmartThings but still drops connection randomly - but not as often. Wish I could go back Oreo, was very stable then!

I took my car in for a service today and I told the service agent about the bluetooth dropping out. He told me they received a memo from JLR that the issue lies with Google and the various phone manufacturers and that the dealers cant do anything.

People need to remember that not everybody is conversant with pie, jam tart or whatever the version is called .
How about we stick to numerical version which everybody can understand without having to look up what it means.
Thanks.

I've got this one now aswell. My Galaxy Note 8 has been fine all the time it was running Android 8 but last week it finally got Android 9 and the issues started. I had a bit of a play yesterday and deleted and then re-connected. I then sat there and watched the car settings...

The bluetooth in the car unticked by itself and the options went grey. Then after about 10s, the tick re-appeared and the options turned white. The phone and car connected and held for a few seconds and then the bluetooth in the car unticked and the cycle repeated.

Interestingly, after about 5 cycles i was about to give up when i noticed the phone was asking confirmation of access to the contacts, despite me having allowed connections when i first re-connected.

This morning, it connected, disconnected, re-connected and then appeared to stay stable.

I'll see what happens over the next few days...

I can tell you now mate, after a week of using it the bluetooth cycles until eventualy it becomes stable. Sometimes it takes once or twice sometimes five or six! It seems to connect ok but as soon as you select bluetooth as source for audio it freaks out.

On a plus note, the audio seems to be louder now than previously and better quality.

Oh joy, i only use the phone on BT so that may be why it appears stable.

Although, the fact the car BT appears to cycle and not the phone does point in the direction of JLR. That said i guess the phone could be crashing the car side but i suspect it's a change in the way bluetooth works that the car doesn't like and they certainly won't want to put any resources into it so we will have the eternal finger pointing exercise.

I just upgraded from a iPhone 7 to a Samsung Galaxy S10+ and starting having this issue.
Also, my colleague is experiencing the same issue on my car with his Samsung Note 8. (happened since the android update)

So after some testing I have found out that if you disconnect the voice, music works fine without interruptions, but when both are online, it seems to crash the car's bluetooth system. (if you look at the bluetooth setting, you can actually see it completely disable -> enable)

I will try to fiddle with the bluetooth options under the Development Options to see if downgrading any versions / settings could solve the issue.
