Bluetooth can't auto connect with car audio - Xiaomi Mi 10T / 10T Pro Questions & Answers

I'm on miui 13 and I have annoying issues, the device's bluetooth which unable to auto connect with car's head unit. The only way out is to unpair then pair them again. That being said, if bluetooth turned off, it can auto connect as long as car's engine still on. That did not happen to miui 12.5 which rapidly auto-connect. Anybody has any idea how to fix this?

BMW NBT?
I also have this problem. With iphone works properly.

I managed to get it fixed by putting the car audio in bluetooth connection mode, go to bluetooth app then toggle allow fullscreen app. In connect state it will disconnect then reconnect. In our case, it'll force connect to nearby previously connected device. That leaves another issue, which is media info won't update. So we kinda stuck with first song info or podcast title, then it won't refresh. Probably due to xiaomi policy to limit data transfer or simply unresolved bug. Luckily I have Samsung device which I use most of the time in this regard.

A2DP Blueooth Car Stereo won't reconnect to mobile

A2DP Blueooth Car Stereo won't reconnect to mobile
I have the Pioneer DEH-P9800BT Bluetooth Head Unit in my car, which supports stereo BT music streaming from any A2DP device.
I also have the HTC TyTN II Mobile which supports the same.
I have paired the two devices, and on the initial pairing successfully played music from the HTC through the Pioneer. When that worked, the BT Audio icon appears in the title bar of the mobile (headphones with a musical note in the middle).
However, after switching off the car and later returning, I have 2 issues:
1) It is impossible to reconnect the BT stereo music playback, unless I delete the Pioneer device from the list of BT devices within the mobile phone, then pair them again. Nothing else seems to work. Simply, I just want all music to be routed through the Pioneer whenever it is in range of the mobile.
2) I have set the mobile phone as "Phone 1" in the Pioneer, and have enabled "Auto Connect", yet it does not auto connect. Every time I get in the car I have to manually scroll to Telephone>Function>Connect Phone>Phone 1. You can imagine what a laborious pain that is compared to my previous 5 year old Nokia Bluetooth Car Kit which just auto-connects whenever my mobile is in range.
Are you able to solve either problem?
Im having the same problems with my sony DR-BT10CX and Moto HT820 whenever i turned either devices off. But whenever i turned them back on, i usually uncheck and recheck the headset whenever i want to use A2DP. It's a pain but i never had to re-pair my device with my tilt.
Try unchecking/checking the bluetooth device instead of re-pairing them (although in your case, its a PITA).
Have you tried updating the firmware on the Pioneer (if its possible anyways).
I have an ATT Tilt w/ the my customized HTC rom. But my JVC BT1 never has any problem to reconnect to my phone.
1) I found a program called A2DPToggle which provides an on/off button on the home page to solve this
2) I found I have to leave the phone in 'visible' Bluetooth mode for auto-connect to work. Less secure, but solves the problem
While this may not help, while messing with my Audio linking between my pda and pc , The PC BT adaptor would freeze if I tried to stream an AAC file or a non mp3 file. It would play it for 10-15 seconds then freeze. I imagine not all mp3
s are created equal for BT purposes either.

Mine has not done this with my Jawbone Icon, Motorola S10-HD stereo headphones or my Volkswagen Tiguan. Perhaps you might try another bluetooth device?
buletooth issue?
I had try different device and do the same thing, like my audi q7 and jarba headset and the garmin. Can you tell me what buletooth setting you are using?
Mine has intermittent issues as well, I'm using an older Motorola 710 BT earpiece. I'll only turn on BT on the phone when I know I'm going to use the earpiece, such as when driving or needing to be hands-free. I only activate the earpiece after enabling BT on the phone, but there are times when the earpiece does not connect.... the only fix is to reboot the phone. Is that similar to the issue you are having?
I'm having issues connecting to my car. If I reboot the phone and connect it will work. But once it's disconnected and I turn bluetooth off and then back on from the phone, it will not connect. Only way to fix it is to reboot. Don't know how to fix the issue. Never had a problem connecting my Sensation to my car's bluetooth.
My issue is similar in turning bluetooth on and off via the power widget and not being able to re-connect to my bluetooth earpiece after a few cycles. I'm wondering if it may be an issue with it being BT 2.0 versus BT 3.0 on the phone?
I thought it was my car but a lot ppl is having this issue too.
Sometimes it wont connect but it says connected so i have to go to BT settings and click where it says connected n overwrite the connection for it to work if not gotta restart the phone. :/

I'm having problems with a SoundFly FM Transmitter in my car.
At first it took forever to pair. And even when paired & connected it's really glitchy.
I'm using this mainly for GPS turn by turn over the car sound system. But because it is glitchy I can't use it because some of the directions get cut off.
I had a MyTouch 4G before. No problems whatsoever. I don't if it's a hardware or driver or BT device issue.
I'm willing to get a new FM Transmitter but not if it does the same thing.
It didn't work well on stock or rooted w/ Juggernaut rom
this is quite annoying. I wonder why this topic died so quickly, there have to be more people with this problem? Maybe has something to do with a bluetooth power saving sleep feature? Streaming music, pause music for a few minutes, incoming call gets connected but I get no sound through headset.

Better control of auto Bluetooth connections?

My g3 is completely stock like my last few phones have been.
I am looking for better control of my Bluetooth connections that automatically connect to various objects. All 3 of my connections have call audio capabilities, and I only want to use 1 for call audio. However when I get in the car its a 50/50 gamble of what will connect to my phone as the priority device resulting in me having to go change the settings every time I drive.
Here's the situation:
My car has 3 BT connections I currently use when I drive.
Priority 1: Car OEM Bluetooth connection. No audio streaming available so all I want is automatic connection for hands free through my car speakers and steering wheel controls for phone calls.
Priority 2: Garmin GPS traffic. My GPS uses an app on my phone to get traffic reports. It only needs the BT connection to communicate with my app. The problem is My GPS has hands free call audio also, but i dont use that feature and never want to. However it seems I frequently have to go uncheck the box "use call audio" in phone BT settings because this sometimes connects to my phone before the car BT does.
Priority 3: sometimes when I am not using my iPod for music I use an adapter for streaming music since my car does not offer that feature on its BT connection. Of course this adapter also offers call audio and media streaming. When this is plugged up and listening to music I have to disconnect my cars BT (listed as priority 1) as it will cause static in my music streaming. When I use this device I shut off the connection to my car and just leave the GPS (priority 2) and this connected and make phone calls by hand without hands free since this adapter does not allow me to use my steering wheel controls etc that the car has and its just easier to do it by hand. I don't always use this adapter, only when im board of my iPod and sirius and want to stream Spotify.
I've tried "Bluetooth auto connect" application but it hasn't done anything to help control which device connects and which doesn't or which of them has priority. A lot of the times I'll get in the car and disconnect all of them and start over but usually one of the devices automatically tries to reconnect causing them to interfere with each other while I'm driving. Unfortunately none of these devices have the ability to shut off features in the devices themselves which means I have to use my phone to control them.
Is there any way of controlling my bluetooth connections in more detail or am I just stuck with them battling each other every time I get in the car? Usually I don't have a problem once they are all set but if my phone restarts or I I need to start all over. If the phone would just remember which connection uses "media audio" or "call audio" this all could be avoided but the phone never ever remembers and always resets them all as checked. My Bluetooth is usually always turned on (probably what kills my battery) and I have no other connections besides what I use in the car. I had the same problems on my Xperia Z1 and don't think this is an LG G3 specific thing. I think its an android thing in general.
Thanks for any ideas.

Problem related to watch and in-car handsfree Bluetooth system

My watch is on DP5 and works perfectly but for some reason, when it is connected to my phone, it prevents my car's handsfree system from connecting automatically with my phone. I can easily connect to the car manually by going into my phone's bluetooth menu and selecting it, but it just won't do it automatically. If my watch is not connected to the phone, the phone connects automatically to the car without issue. I didn't have this problem with my Moto 360, so I know it's not an issue caused by my phone or the presence of a watch. Has anyone had and fixed this issue?
EDIT: Fixed it. If you have the "play phone audio through watch" option enabled, the phone recognizes the watch as a bluetooth audio output. Since the phone cannot be connected to two audio outputs at once, the car system will not automatically connect. This option needs to be off if you want the car to connect to it automatically.

OTA May 2018 Update + Car Bluetooth Music issues

Hi all,
Has anyone experienced any weird Bluetooth issues after installing the latest May OTA update (OPM1.171019.011-RZR-180509.5038)? I've realized that the BT controls on my 2015 Nissan Sentra no longer work properly. It doesn't automatically connect to BT anymore and no track information shows on the head-unit. The weird thing is that I CAN get music to play, at least.
I just wanted to know if I happened to be losing my mind after numerous reboots and re-pairing between the car and the phone.
Same for me. I can delete it. Pair it again and it works. Next time I get in the car it won't reconnect.. worked fine before the update at the weekend.

It's a fire an miss actually. Sometimes it reconnects automatically with the car's unit (alpine aftermarket) and sometimes it doesn't. I had noticed that if I get in the car for the 1st time today (for ex), it won't reconnect back and i have to cycle around the input in order to "kickstart" the reconnecting process. If I make a stop along the way, stop the car, get out (thus interrupting the connection) and getting back after a while, it will reconnect automatically without any issues. I'm not even taking it out of my pocket. But this scenario is happening since day one, not necessarily from the last update.
On the other hand, I got a smartband (coincidentally after the last update) and now, while the smartband is connected via BT, when I turn on my BT wireless headphone adapter, it won't re-connect anymore (simultaneously with the smartband) and if it does, it's without media playback. As a workaround, I have to 1st turn off the smartband, clear the BT of any active connection (And also any other device with media playback capabilities), turn on the BT adapter so it will connect full, then turn the smartband back on. And not always works like this.
So, I do have on an off issues with the BT stability and connections with various devices, not just car unit.
Strangely though my smart watch connects no problem and the stereo in my motorhome was connecting at the weekend. It's just the car ( a Vauxhall Astra) that refuses to connect unless I delete and re pair....

I can't get music to play with Spotify or YouTube. The phone connects fine, shows song info but just won't play no matter what I try.
The weird thing is that calls work perfectly. Sound through car speakers and mic works. Just doesn't want to play music.
I've tried unpairing, re-pairing, deleting, even factory reset on both phone and stereo. Worked fine before the 8.1 Oreo update. (I'm on 3 UK handset).
Im having issues as well, it will connect the first time when I manually connect the phone and stereo to MyLink. It will say connected but (No Media) so i try to pair the media and it disconnects my phone from BT and then i have to delete device and re connect device manually. As well if i leave the vehicle or turn it off then it will disconnect. Not just my vehicle but the other showroom vehicles do that as well. Can someone let me know if there is a bluetooth upgrade or a firmware upgrade that can fix this problem? is there anything that we can do for this let me know. Thanks!!
I am having the same issue in my bmw.
I can delete the phone and re-pair... But it sucks having to do that every thing.
also having issues as well. It connects to my headphones and the after market HU in my truck but it will not connect at all to the factory HU in Genesis Coupe. I have tried to delete and re pair and still nothing.
So currently it all works for me with the latest update. It definitely takes a little bit longer than normal though. Not sure how long some of you waited, but compared to my old phones it feels like an eternity during the time it doesn't connect. I also use a smartwatch and it is always connected to that. If you guys need or want any files, let me know. I'm currently waiting for a usb-c to usb-a cable in the mail, so once that is here I can try to help.
I think this is all more of an Android issue. I was having most of the exact same issues mentioned here on my LG V20 on Oreo.
I just for a Razer Phone 1 off eBay this week. I did the Pie update and within a day, the bluetooth issues have returned. Sometimes phone won't connect to car stereo - sometimes reboot stereo, sometimes toggle phone bluetooth off/on, or sometimes just wait 10-30 seconds. Doing the same showing info on car stereo display, but no audio transmitted. I also had similar issues using a OnePlus 3 with both Dirty Unicorns and Resurrection Remix Pie ROMs. I was beginning to think it was my car stereo until I read the comments on this thread. Seeing so many others having the exact same issues on factory and aftermarket stereos (mine is an aftermarket), and knowing it's happening on different devices and both Oreo and Pie , I'm thinking it's an Android 8 and 9 issue.
