Bluetooth Not Connecting - Worked Previously - MTCB Android Head Units Q&A

OK, so I got everything working on my unit back in November. Bluetooth worked fine and connected with my phone and OBD device (OBDLink LX).
Suddenly within the last couple of weeks, it's stopped connecting. I have tried rebooting the radio, unplugging/replugging my bluetooth OBD, unpairing the phone, repairing, etc... Nothing seems to work for more than a few minutes. Sometimes it will work for one trip, but then the next trip it's back to REFUSING to connect to either bluetooth device. Remember - BOTH worked before, and I didn't change anything.
Since it's happening with both my Phone and my OBD device, it appears like it is a fault in the stereo. I really don't want to do a full factory reset as that would entail many hours sitting in the car wasting gas idling while I reinstall/reconfigure EVERYTHING only to not even be sure it won't do this again.
Anybody have any tips on something I can do to fix this? There does not appear to be any kind of "unpair" option in the bluetooth settings on the radio itself. I'm wondering if there's a way I can manually reset just all of the bluetooth settings - blow them away and start over without resetting the whole device.
This is a pretty big deal - one of the #1 reasons I bought this device was for OBD datalogging. If that feature does not work, I will rip it out of my dashboard and ebay it. PERIOD...
Adcice?

Nobody?
I tried changing the bluetooth device name, changing the PIN and re-pairing my devices. They work intermittently, but 90% of the time won't connect, or if they do, they won't stay connected.
This is turning my radio into an expensive piece of garbage...

Try keeping wifi on all the time (even if not actually connected to any network).

I do have Wifi on all the time. I have an LTE Hotspot I keep in the glovebox of my car that powers up as soon as the car powers on. So there's 100% wifi coverage for my stereo no matter where I'm at.
I can randomly get it to connect, but it won't stay connected. When I'm in the bluetooth menu, the devices will actually disappear from the paired devices list. Both paired and available will go blank just suddenly as the devices drop off. Then they'll reappear on their own. So it appears to be the bluetooth stack is crashing - but I'm not sure why.
It is a KLD RK3188 unit. Running latest MCU (came preloaded, just bought it in November - I haven't put a new MCU) and recent firmware, which is a stock firmware, not MalaySK (MalaySK doesn't support the digital display below the screen on my unit)...

At this point this unit is trash if I can't keep Bluetooth working more than 10% of the time.

Some smartphones might show an incompatibility with the radio's BT stack. To be sure try with another smartphone.

I would see if it pairs reliably with just one device at a time. My phone has issues connecting with the HU if I first connect my BT headset to the phone but works fine if I do it after. Also the construction of these seems to be sub-par and it could be the bt device or antenna in yours was not connectec/mounted well and you hit a pothole and now its not attached/broken/loose. It may be worth opening and looking inside for something that broke off or is loose. Finally, I have had (well still have) my factory settings change randomly and have to go in and reset. There are settings in the for BT module and it may be worth looking to see if yours are correct.

I also have problems with mine but I'm running Marshmallow in my OPO. As soon as i go back to Lollipop (CM 12.1) it works again.

Turns out I think it's the OPO. Mine has issues even with 12.1. I think it's based on Modem version not firmware version. Your modem may have been changed when you went back to 12.1.
For me changing modem versions is something I really want to avoid. I hunted forever for a modem version that didn't constantly drop WiFi and LTE, finally found one, and I think that's when the Bluetooth issues started. Every time I flash a modem to the OPO it becomes a nightmare. That phone really does not want you messing with the firmware which is not what I expected when I bought it.
For now I'm back on my old Nexus 5. No problems. I may just sell the OPO and never stray from Nexus again.

Hmmm.
My OPO doesn't connect to the headset but my chinese BT OBD dongle connects fine and works.

I have the same problem with my unit but phone working.Only obd2 adapter some times not connecting.Have you find any solution?

I have a similar issue with the Pixel XL.
Previous I was on a Nexus 5 Bluetooth worked perfectly every time without fail, could make calls, listen to music and sync address book no issue.
Now since moving to the Pixel XL I have an issue connecting to the head unit. The head unit shows as a connected device, but then flashes green then grey, green, grey showing connected, disconnected... I can still stream music from my phone over Bluetooth, but voice is not achievable.
Like suggested it's likely to be the BT stack in the handset rather than the head unit as works fine with Nexus 5. Highly frustrating and likely no fix unless it can be patched by software update

I'm also having the same problem as you noodlemctwoodle on a Nexus 6P with 7.1 developer preview.
I've un-enrolled from the beta program this morning, waiting for the ota to come down, as soon as it does will re-test and let you know if it's working, as I suspect it is a problem with the bluetooth stack in 7.1

MTCD MLT (Xtrons TD618AS) Bluetooth and OBD Reader
I have had issues with the Bluetooth on the MTCD MLT V1.76_1 (Xtrons TD618AS).
I found a work around which allows me to use the OBD reader successfully. I downloaded an Android Bluetooth App and toggled off the Bluetooth. Once the Bluetooth was toggled off I was able to access the OBD reader by using the "Piston" OBD app. I tapped on the car picture and waited for the app to think about things. Once the app finished thinking I was able to start capturing the live OBD data by pressing the play picture. I am only speculating, but I feel as though perhaps the firmware engineers goofed. This is even the OBD reader that Xtrons promoted as compatible with the TD618AS stereo I bought with it at the same time. Not to mention that I continually lose FM radio even though the stereo was professionally installed and no wires were cut. I was very excited, and now only depressed.

Has anyone encountered issues with connecting with a car bluetooth? My wife phone conntects with no issues.. She can use the cars remotes to make and receive calls.. Mine I have to pick a contact from the phone for it to work, it will not work with the car or my work truck controls.. It seems everytime it ask if my car or truck can access my contacts, I always choose allow, but nothing happens, but it works with the wifes.. This is with the Lollipop update, that we both have...

Got one to work, in my truck.. The car it worked for a while, then quit.. I will try it agian to see if it will stcik... Most likely caused by the 5.0 update..
I've noticed a Bluetooth problem that suddenly started in the last week or so. I upgraded to Lollipop when it first hit, and didn't have any problems.
Now, however, after Bluetooth works fine for awhile (I can connect to a Pebble watch, Bluetooth speaker, car Bluetooth, etc) all day long - then all of a sudden it can't connect to ANYTHING. Toggling Bluetooth off\on doesn't fix it.
Restart the phone, then everything works just fine for awhile. Until it doesn't, and I have to restart again.
Anyone else experiencing this pattern?
I've actually had the opposite happen. I have a iSimple bluetooth box in my car. I've never been able to auto connect with either VZW Note2 or 4. The CS rep told me it had to do only with VZW phones and he couldn't help me out. On another forum, another member mentioned he didn't have any issues with his older phone, so I dug out my old HTC Incredible. Sure enough, it would auto connect. Something changed with Lollipop, and now my Note4 will finally auto connect to the iSimple box. I tried using a third party Bluetooth app prior, but it didn't fix the problem.
Finally got the one in the car working as well... Because the wife and I have the same phone, I just simply changed the name of my phone and it works fine..
If your talking about the developer edition one rom update.. YES.. What fixed mine was wiping everything and redoing the one rom lollipop, then twrp, then installing Ricks Rom Lollipop, things have been perfect. I even addressed it in the ricks rom thread the week.
I haven't had any issues connecting devices but since Lollipop, when I am connected to a bluetooth speaker (car, bose, other bluetooth speakers) the audio gets choppy randomly.
I have done some searching and found others (LG g3) who had the exact same issue after updating to Lollipop.
I have tried rebooting, using different music apps, unpairing/pairing, forgetting the device ect and nothing seems to work. Anyone else having this problem after updating to lollipop? Anyone know how to fix it?

Bluetooth Car Sync Issue

Is anyone else having issues syncing to your car? Mine connects for 5 seconds and then flashes phone not detected on my phone screen and disconnects. I am running the deluxe standard model, not the special edition. I have checked the easy stuff like making sure Bluetooth is enabled and successful pairing. I can connect to Bluetooth speakers no problem. My Google music app also froze and could not be recovered by powering off or closing apps. I had to uninstall and reinstall. Let me know if anyone has had a similar issue and hire or if you fixed it.
I listen to music in my car via A2DP/BT Audio & have no issues with either listening, or controlling (fwd, rewind, etc...) music apps like VLC via the car controls.
no problem pairing with my car, mobile, music etc etc.

2 ppl confirmed properly working BT;
1: make sure you're on the latest firmware
2: close any other apps which might be using BT (do you have other BT devices on you? They might be conflicting)
3: make sure your music app is whitelisted in battery optimization options
4: try other music apps, like VLC
5: choose balanced power management
6: factory reset & try BT audio as the 1st thing after a fresh boot; this should help you isolate the issue.

I have the same issue sometimes. My Honda Accord had no issues pairing to my Note 7, and connected to it perfectly every time. The car also initially paired quickly to the ZF3D, but when I get in the car I have to manually select the car in the Bluetooth menu. If I try waiting, it will either never connect, or flash like yours. connect for a second then lose connection.
either way, manually selecting it makes the phone keep its connection throughout the entire drive.
Hope it helps!

Thanks all, I tried all of the tips above to no effect. Manually selecting still drops within 5 seconds. Tonight I will try it in a different car to rule out a compatibility issue with mine. I aIso downloaded VLC and made sure everything was white listed. Phone reset had the same issue with no apps installed. My old Note 4 pairs just fine and stays connected. The Buick Bluetooth (2012) system isn't the most up to date either and has limited capability (phone only, no music) so it may be a car issue.
Thanks,

I am finding that auto connecting to BT in the car and on my Gear S3 is hit and miss, however i have had no issues when doing it manually, but it is a pain in the ass. hopefully ASUS will fix this when they release the nougat update!
My Zenfone 3 will pair with the car and a number comes up that I have to type into the phone but the keypad flashes up on the phone for 1 second and then disappears too quickly to enter it. I have tryed it about 10 times and always the same result. Anyone have any idears on how to fix it.

O update and bluetooth audio

So I had been on the beta version since it was released and participated a few times in the thread here: https://forum.xda-developers.com/pixel-xl/how-to/android-o-beta-issues-t3609335 and others were having the same issue.
The issue is no song/artist information being displayed on my touchscreen stereo, and I cannot use the stereo to pause/skip to the next track (I have to do it through my phone). Ive tried a local audio player, Google Music, and Pandora all to no avail. The deck is a Pioneer double-din AVH-P8400BH.
In my daily car, my phone bluetooth name appears and I can change song ect thru the deck. It is not a touchscreen and it probably 10 years old.
Ive gone into the bluetooth settings and have tried changing the AVRCP from 1.4 to 1.6 (neither work), and audio codec from default to enable optional (neither worked).
Anything else I should try out?
TIA

mine has awful streaming. It has so many skips...snags...audio blanks...whatever term you want to call it....its not "uninterrupted".
I was hoping google IMPROVED Bluetooth. I don't understand why they have this struggle to be honest. Its 2017....Bluetooth is not new technology.
Maybe they should stop expanding their department to provide data to the government to spy on private citizens using smart devices, and they would use those resources to fix bluetooth
Pioneer brand head units in particular I have seen Bluetooth streaming issues when paired to flagship model phones for years...even back as far as my LG G3. I got a Kenwood head unit instead, never had an issue.
As far a the Pixel XL and BT streaming...I have only had issues with dropouts zap sounds or pops, when i am out mowing my back property with my tractor...phone in pocket and BT headphones on. But my previous phones did this...most certainly due to the railroad nearby and high rise high voltage power lines and towers that are above me in that area.

Pioneer uses a cheaper bluetooth and never updates the firmware of the chips to fully support the available Bluetooth profiles even when they are developing their units and new profile updates are available. I have had a very long and annoying history with them to the point where I was in direct contact with their build team after all my complaining. That was back in 2012. Never used another of their products again. :good:
I have the same issue on my Chevy Colorado 2017. Everything works fine on Spotify on my Huawei Mate 9, and iPhone 7. It also worked fine on 7.1.2. Spotify works and music comes through but no info is displayed. I unpaired both things with no success. Frustraring.
I tried unpairing mine as well, no luck either

I have not. Ill give it a shot today.
No idea if this problem is related or not but might be worth a check if you have time. First time I put Oreo on my phone it was fine. Then I screwed something up and just ADB flashed the image again. Everything was fine until I tried bluetooth a few days later. It wouldn't connect until ticking that media box many times. Then I flashed the image again and it worked fine again.
So I just got the 8.0 OTA (not on beta). I see in the dev options that it shows what BT codec it is using.
I have noticed that only the option "Bluetooth AVRCP Version:" is the only value that changin it does it stick. The other setting appear to be on auto and revert to auto depending on what device u pair supports.
My first test on my Kenwood KDC-BT762HD it paired fine and it said it was using AptX. Streamed for a few min fine. Then after I got back in the car and it auto paired, music started skipping every several seconds. I turned radio off then on to repair it and it started streaming fine again....but was using SBC according to Dev options.
When I changed AVRCP version to 1.6.....it connects and uses AptX fine. However, the radio display no longer displays the BT media metadata(title/artist), but the controls on the radio still work. I change to AVRCP ver 1.4 and that restores metadata, but then it uses SBC again. (using ver 1.5 results in SBC and no metadata).
I don't really care about the song info not being displayed on my radio....but definitely seems to be something fishy with BT in this new update.
EDIT Update: so now I am noticing it auto re-connecting and using SBC all the time now. WOnt use aptX unless i delete the device and re-pair it. then it works for a few reconnects, but then drops to sbc cagin.
Thanks for posting, I won't be updating. The Bluetooth has never been right and now seems to have regressed.

i agree and although i dont get the proper song listing on my car stereo it seems everything else is better. on nougat my BT headset i use for work all day (moto buds) would often stop connecting properly and i would make a call and have to select "phone" then "headset" again to get audio back on headset and om Oreo it happens less frequently

If you switch to a rom that uses the CAF based bluetooth (all lineageos based ones should, crDroid does for sure as that is what I use) implementation this won't happen. Still haven't been able to track down exactly why, but for now I'm sticking with CAF based ROMs to avoid this.
Do any of you guys having this issue have an Android wear watch? I've had heaps of issues with Bluetooth streaming being all "jittery" and just skipping since the update. However, I found this is basically completely fixed when I turn my android wear (LG urbane) off, or at least the Bluetooth on it.
Tried all the developer options for BT but hasn't made a difference. At the moment, my solution is turning off BT on my watch when I'm listening to music. Bit crap but it works.
I have factory reset the watch and cleared BT cache on pixel.
Any other ideas?
Is anyone else still having problems with Bluetooth on Oreo? I was hoping the official 8.1 release would help me, but I'm seeing no change. I have a Kenwood BT952HD, and experience issues similar to what the OP describes. Audio is plays fine, no unreasonable stuttering. But I get no song info, and can't skip tracks. Also, the pairing isn't as automatic. Every time I turn on the car, I have to wake the phone up, and wait for the pairing to complete, which takes longer than usual.
I've tried playing with the AVRCP settings, along with clearing registrations at both ends and repairing, with no luck. Is anyone else still seeing similar issues?
8.1 working fine with my Kenwood BT762HD. I use PowerAmp v2 alpha build 704 app.

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.
Sent from my Phone using Tapatalk
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.

Bluetooth and Car Audio

Anyone else having issues with connecting the 7T to their car and getting audio going out of it? My OG Pixel didn't have a problem, but I have to toggle off/toggle on Bluetooth and then manually tap the car's bluetooth listing to get it to actually 'connect' the audio portion.
Rather annoying, considering I'm only in the car for a few minutes at a time, this either eats into the time entirely, or makes me sit in my car for a couple minutes before even driving to fiddle with the bluetooth settings.
Car has stock headunit, 2015 Evo X. Like I said, original Pixel XL had no issues, but this is annoying. I've tried changing bluetooth versions to no avail. I can see it connecting and dropping the bluetooth connection fairly frequently while staring at it and trying to 'get it going'. But once it connects, it stays there.
My bluetooth headphones (Some knock off cheap Chinese ones for $20) don't seem to have an issue.
My connection to my aftermarket stereo is fine. Just seems a little quieter than my last phone. Connecting is kind of slow too when I start my car but it is automatic.
I don't have any issues with connecting to all 3 cars (2014 Honda Accord, 2009 Pontiac G8 Gt and a 2018 Honda Fit) but I do agree that the volume seems a little lower than my previous phone (Galaxy S8).

Hmm. Weird. Is there anyway I can check for logs to find out what exactly is happening? I haven't rooted, just don't know if it's something I can naturally pull from Android as a whole.
I had the same issue, but when I made the phone discoverable and initiated bt from the car stereo it seemed to work.
I also set a custom pin , not the default 0000
My bluetooth is quiet, but its also static-y. I never had any issues with my G6 and now I get static clipping every 10 or so seconds. Its unbearable.

I'm not really having an issue pairing it, but it's just connecting after pairing is the problem.
I have changed the default pin. I can see it popping up and down the car stereo a few times in the bluetooth settings before it just gives up.
As for the other issues, I'm not having a problem at all with audio volume, nor popping/static when it finally does connect.
My volume is super low when connected to Android Auto and streaming music. Have to turn the radio up to max. However, I'm assuming that's an AA issue or Android issue, as it seems many others are having the same problem with different phones. Been thinking of adding an aftermarket amp to the car. Maybe I should pull the trigger. Lol

Be careful that a bugfix doesn't come and blow your eardrums out, lol.

LOL that would be my luck

My OnePlus 7t connects fine and phone works for calls on 2014 cts. The sound comes out of phone can change song on head unit but I can't get audio to play through car. Anyone else get this?
Yeah music stutters with car player... Only calls work. Music works on headphones etc. I couldn't find solution, did network reset, cleared cache. Nothing works.
Seriously!
I've wasted at least two hours already trying all the recommended steps: from flicking icons on and off to a full phone reset.
Still no connection to my Suzuki S-cross car. Multiple previous phones have connected effortlessly.
Even the $50 temporary five year old borrowed phone could handle it.
Anyone got any other suggestions? Yes, tried the AVRCP setting change from 1.4 to 1.6. That didn't work either...
Barebones system reset from scratch running O2 OS 10.0.6HD65AA
Any suggestions greatly appreciated.
I need to be able to talk and drive!
Reset the car radio and clear all pairing data if you can. Then try again.

Thanks for the suggestion.
Tried that.
Tried one other car - no problems.
Tried a tablet and a very old phone with the car and suprise - the car's bluetooth seems to be the problem.
I will try and find out if I can fix the car!
UPDATE: Morale of the story - read the car manual very very carefully and go though each tedious step = SUCCESS

Yep most have lots of tedious steps that are different model to model and if not followed exactly will cause this problem on occasion..
In my case music starts to be scrambled after 10 minutes or so of listening. When I take the phone (so the watch pops up) or turn on the screen it immediately works fine again, but when being put aside and the screen turns off, the issue starts again ..
Also in the early days of my previous 5t I had the same issues but some fix was delivered together with oxygen os update. And now the same story again
I have a different issue with Bluetooth:
- OP7T connects to car Bluetooth fine
- I can make/answer calls
- Bluetooth media works fine
The problem is with Google Assistant & car audio:
- it was working as intended until the latest update - 10.0.15 - I was pressing the button on the steering wheel the google assistant was answering questions through the car bluetooth, no need to switch to bluetooth media.
- after the latest update, when I press the button on the steering wheel, Google assistant pops on the phone , starts to answer question, but cuts off after 5 seconds. the command still goes through and Assistant still runs, but does not come up on the car audio.
- it looks like the Assistant is not connecting to the car as a hands free, but as to a bluetooth handsets.
Anyone experiencing this?
