iPhone 11 on iOS 13 having Bluetooth connectivity issues

I contacted the uConnect support line last week, and I got a call yesterday from them. When I initially contacted them, they asked for some information on my vehicle and radio (specifically the software version that was on it). It turns out that there was a software update that needed to flashed to my radio. They provided the instructions on how to do that, with links to find the updates. They also gave me a couple of methods to do factory resets on the bluetooth module in the car. They also told me that the most recent iPhones are not listed as "100%" compatible with any uConnect products. The most recent one they say is the iPhone X, and iOS 11.x. I'm not sure what to make of that. But I did the update today, and since then my phone has connected each and every time. I'll keep an eye on it for a week or so, but it was nice to see that they did respond, and seemed concerned about my issues.

I found out from Mopar that I had an update that needed to be done to my radio. I did that, but still had connection problems. They also gave me instructions on how to reset the bluetooth module. Since I've done that, the only connection problems I've had is when I have my Apple watch on. Otherwise it's connecting all the time in my 2015 Dodge Journey.

😳🤔 do other Bluetooth devices come up on the iPhone 11 ? If you have your phone backed up I’d try a complete hard reset and then before you restore it try it and see.. if it connects then don’t unless you really need to restore it .. redownload all apps and then try that maybe something like mine, I believe I have a software issue with mine. I’m going to restore it back to factory and see because apple just sent me a new phone and it worked flawlessly and when I restored it same old problem so it has to be something in the software an app or something I’ve never done anything out of the ordinary to my phone.

yes is try that but back it up first!! see if it works without installing anything just like brand new iPhone and if it connects there is something wrong with your backup meaning something installed or something interfering with your connection to your car.

Same here...Watch/iPhone don't Bluetooth together with car Bluetooth since IOS 13 came out...Been working with Apple they do know about it now but there is no conclusive fix right now... Here is how I get around it: instead of leaving my watch at home, I turn my watch Bluetooth off before I get in the car and I can connect Car with iPhone 100% of the time. Then I will turn the watch Bluetooth back on when I get home or NOT in my car...

Still no problem here for me with iOS14.

I deleted the connection both in my iPhone and in the car. Restarted both before reconnecting. I did not use the old faulty connection.

Have you done the same?

I have been running IOS14 for a week now, wanted to wait a test a few phone calls in my car before writing this. Since installation of the IOS14 update I have had no phone connectivity issues in my car

I still think it’s a flaw in the original program. You just reload it when you do a reset and/or a full restore. I pulled the lead when my laptop said I had finished clearing the hard drive. Switched the phone off then restarted the phone and did a fresh reload from iTunes. It cleared it, now works perfectly. It’s worth a try.

An update on this issue for me. I never got my "11 Pro" to the point where it would reliably pair first time with my 2008 Audi. It would pair quickly, hold the connection for a minute, then drop it and refuse to pair until I manually selected the car in /Settings/Bluetooth a couple of minutes later (why a couple of minutes were needed I don't know). After that the connection stayed up and I never had a problem. So it was frustrating, but I could live with it. I never had an issue with other BT appliances including AirPods, Beats, BT in our 2012 VW, Jabra BT speakers etc...

I have since disposed of the "11 Pro" and bought a "12 Pro". This works first time a charm. No issues at all. Just like my old "X" and the iPhone I had before that.

Net net is that there seems to be a hardware/firmware issue on the 11 which causes issues with older (legacy) BT stacks. The "12" has fixed the problem.

Did you try deleting the connection from both car and phone, then re-pairing?

I hate to repeat myself, but I have had issues in the past and that often resolves it.

13.1.1 and soon 13.1.2 hopefully a fix

See if disabling the Wi-Fi while BT is connected takes care of the problem.

If it solves the problem, you can automate it via Shortcuts.

Same here, disconnect my Tag Connected watch and music streams perfectly in the car via Bluetooth. Re connect it and constant sound drop outs

Once you turn off the watch, forget the device you're trying to connect to, then turn blue tooth off/on and reconnect it will work (with the watch off).
