Sony Xperia M5 dual bluetooth not connecting to android car radio - Sony Xperia M5

Hi
My Xperia M5 dual (E5633) with latest firmware 30.2.B.0.100 doesnt stay connected to my Android 4.4.4 car radio. The radio has the RK3066 chip and latest MCU ver and it is rooted.
The issue i have is, once paired it connects for a few seconds the disconnects repeatedly and it does this until i unpair or connect anothe bluetooth device to my phone. This all started with the Marshmallow update. I can connect ather devices to my phone and radio and have tried a Samsung S6 with Marshmallow and it worked.
I am hoping someone can help as i dont want to downgrade to lollipop just for this one issue.
Regards Matthew

I thought that I was the only one having this issue.
The same scenario, can't conect it to a bluethoot device.
Any suggestions?
Regards

I downgraded back to 5.1. And now it works perfectly. I have tried Sony but haven't heard from them yet. What phone and head unit you have?

I have a E5606 with MM, and already looked for the issue. It's the MM update, I read it here And it seems that a downgrade will do it as it worked with you.

So it seems there is still not resolution for this problem. I am hoping they bring a new update for Marshmallow that solves this.

Looks like it has something to do with the way the link is established. Have the problem where media streaming sound does not come through. Found that if I switch Bluetooth off and on again on the M5, while the radio is on, seems to fix it. Pain that you have to do this every time.

[Q] Bluetooth connecting problems

I got a galaxy gio awhile ago and i´m real happy with it except for one problem......it seem i can´t connect it to bluetooth devices except for other cellphones.
I have tried mine with an OBD2 reader and a wayfinder GPS dongle and a Jabra headset and it doesn´t find any of those 3 devices.
Everything else works fine on the phone and as i stated it can connect to other phones thru bluetooth so it seems to be a program issue.
I really don´t wanna flash my phone with another firmware as i am happy with what i got now and i´m also no pro at reflash this phone so i am wondering if there is a solution only for my bluetooth problem?
I have tried these 3 bluetooth devices with another gio and it connects without a problem to that other one so i know the devices is working in general.
Firmware in my GIO is:
Android 2.3.6
Gingerbread
If you need more to try to resolve this bluetooth issue info just give me a shout.
Maybe someone else have had this kind of problem also!?
Thanks
Try hard resetting your phone.

How? Via CWM or via settings?

Use CWM 5.2.0.8.
It`s really easy.

[FIXED]Bluetooth issues / error with .368 & .216

Hi everyone,
I hope you can help me with an issue I have. It only pops up on the 14.6.A.0.368 firmware. I have tried Customized DE, Customized NL and Customized CE1. And I experience it with all.
When I revert to 14.5.A.0.270 the issue is gone. Also on CM12 I have no problems.
In my search I have not found others with this issue, so keeping to ITIL standards I will not call it a problem .
Here it goes:
Bluetooth disconnects. When connecting to my car stereo ( Renault Clio MediaNav ) the phone will connect, be registered by the stereo ( as indicated by the battery charge indicator on the stereo's screen ) and then disconnect again. With the error: "Unfortunately, Bluetooth share has stopped." See attached image.
I have included the Logcat I made of 2 cycles of connecting and failing. 1 Zipped and 1 filtered on Bluetooth.
Now for the strange part a work arround; If I reboot my phone it connects just fine. But only the first minute after the reboo. Any time longer then that even if no BT connection was made or BT was off and it will fail as stated above.
Well it seems a newer Firmware is out, Not for "My" region yet, but Im going to try Customized DE. See if that fixes it.
If I don't update you can consider it fixed.
Edit: What worked for me was flashing D5503_Customized DE_1279-6978_14.5.A.0.270_R1D prerooted DualRecovery.zip . Restoring all settings trough TitaniumBackup,
Connecting to the Bluetooth device I had trouble with. Verrify that it functions correctly.
and then flash the newest firmware 14.6.A.1.216 ( Also Custom DE ) with flashtool ( excluding Cust-Reset and Fota-Reset ) keeping all user data.
Now BT works as intended.
Why a clean install of the 2 latest rom versions gave issues for me, I still don't know.

wifi stopped working

i have an xtrons hu with kitkat flashed on it. i upgraded to the new lollipop rom and 2 weeks later wifi stopped working. i downgraded back to kitkat today but the wifi still doesn't work. does anyone have any ideas of things i can try to fix it? maybe flashing a mcu or is it likely that the wifi hardware has failed?
I've got the same problem - wifi is dead. An external Wifi adapter doesn't work either although the USB port appears to be OK with memory keys.
It seems to be the same hardware problem caused by a defective inductor very sensible to overheating with the ext USB, look for the solution in my thread,

You dont have an Xtrons head unit, Xtrons are simply resellers, to find out what unit type you have go to settings/about device.

Really, are you sure its not just a case of flashing the latest MCU or re-flashing the latest MCU if youre already running it ? It usually is.

MTCE_MX no wifi

Hello
I bought car with android radio RK3368. I tried most popular roms 9.0 from XDA (also with android 8.0) and always wifi is not working. Also connecting phone by USB cable is not working.
USB is working and I can get internet from 3g modem.
I also tried upgrade MCU and without changes.
How to recognize what model of radio it is ? Maybe it is not MX or something other ?

Cant connect to AndroidAuto

Hello,
I want to use in my car (Ford with Sync3 - AndroidAuto support) a phone with AAMirror.
I found my old HTC 820 with android 6.0.1.
I unlocked bootloader and rooted phone successfully.
Then i Installed AndroidAuto on it (5.5) but when I am connecting phone to my car - car doesn't 'see' phone. Of course with many other phones it works fine.
Maybe somebody had simillar issue and know how to solve it?
Best regards
