Can't connect to Ford Bluetooth handsfree device

Hello,
in a few weeks I'll get my new Ford car - equipped with the built-in bluetooth handsfree device. I tried to connect my MDA 3 to this device at several Ford dealers but didn't get any connection.
The MDA finds a "Ford Audio" but can't establish a connection.
Who has any ideas ?
Thanks in advance - Dieter

I have the same problem with a new mondeo...
Everything works with an old nokia 6630 (with a small nokia application I can browse the phonebook as well) but I'm not able to pair the bluetooth ford audio system with my HTC TyTN...
Any ideas?

try using a newer bluetooth stack.

What is a bluetooth 'stack' ?
And how do I change to a newer one?

As far as I know, you'll need to update the Radio portion of your device's ROM based software (the basic software that drives the device).
The best bet in your case I believe would be to just grab a new complete update for your device by searching the wiki for downloads for your device. Download a newer official ROM, install it and try again.
You will lose all saved data on the device though so back it up>
Wiki is here http://wiki.xda-developers.com/

Did upgrading the bluetooth stack fix this connectivity issue to Ford Audio Bluetooth Handsfree devices?

Same problem. I've tried to upgrade bluetooth stack: my BA finds "Ford Audio" but doesn't connect. Please give us some help

after correct pairing (code 0000), press "Phone" on the caraudio system and then "Menu". After that press left or right joypad on the caraudio to set the "Active Phone". It will search and your phone will be correctly paired.
The last paired phone will be automatically active when you turn on the caraudio system next time.
In some cases will also help to install on the device the JETware application... just try.

Problem Solved!
Thank you dark horse, followed your advice and it worked just fine. I can now connect via bluetooh in my ford.

[SOLVED] Panasonic Link2Cell KX-TG78 Bluetooth connection

I have an Sony Xperia M (C1905) with Root access (locked bootloader) running stock Android 4.1.2
The Sony Xperia M (C1905) supports Bluetooth 4.0 (with added features if we get Android 4.3)
I have a Panasonic Link2Cell KX-TG7873S home (landline) phone.
The KX-TG78 Link2Cell home phone has a USB 2.0 cellular charging port which is a nice touch.
The Panasonic KX-TG7873S provides Link2Cell via Bluetooth.
This supports inbound and outbound Cellular calls (Link2Cell), with inbound caller ID read from contacts.
Calls/communications are transferred to and from your cellular phone via Bluetooth.
Another feature is that the DECT KX-TG78 home land phone can pick up the arrival of an inbound txt messages and alert you on your home phone handsets dotted around the house.
The alert is sounded on all home handsets with "Text message!!... Text message!!".
NOW... The Sony Xperia M (C1905) does support Bluetooth Message Access Profile (MAP) and can be paired and will alert you of inbound txt messages.
Problem
HOWEVER... if you stop/disconnect Bluetooth and attempt to reconnect at a later time (arrival home again) it won't successfully re-pair again.
It prompts with a six digit Bluetooth pairing number which can't be accepted by the Panasonic Link2Cell KX-TG7873S land phone.
I do note the Panasonic OUI MAC address is in a Bluetooth blacklist(blocked) in /data/mics/bluetooth, /data/mics/bluetoothd
Not sure this is really stopping anything as I removed it and it's still removed after a reboot.
Before I removed it the OUI MAC address block, the Sony Xperia M was still successfully pairing the first time with the home land phone.
If I remove any reference to the Panasonic KX-TG7873S (Seen as DECT KX-TG78 in Bluetooth list by default) with MAC OUI 00-08-F0, I can successfully pair again.
The Panasonic KX-TG78 Link2Cell does use a default 0000 Bluetooth challenge PIN.
This can be changed on Panasonic KX-TG78 land phone, but again this makes no difference, that I'm aware of.
I have a Sony Xperia S (LT26i) running Android 4.1.2 which is paired to the Panasonic KX-TG78 on the second line and it's working just fine.
I can just turn on Bluetooth at any time and once paired, it just reconnects without problems the next time using Panasonic Link2Cell.
The Sony Xperia S doesn't support Message Access Profile (MAP)
The Sony Xperia S does only have Bluetooth 2.1
So it may be that the Sony Xperia M is having issues when reconnecting due to Bluetooth MAP.
As this is a long shot, I'm wondering if anyone knows how I could manually alter the Bluetooth connection on the Sony Xperia M so that it'll connect to the Panasonic Link2Cell KX-TG78 without having to manually reconfigure Bluetooth each time.
I've use extended naming in the hope a Google search will invite a wider audience where expertise may come from different practices.
[Update MAR-2014]
Panasonic support did reply and thought it may be something better taken up with Sony.
Fair enough, as I'm running Android 4.1.2 and there is upgrades in the pipeline which may include Android 4.3, so we can look at the problem again after an Android upgrade.
[Update APR-2014]
Upgraded to Android 4.3 on my Sony Xperia C1905 and Bluetooth MAP profile how works.

[ANSWER] Panasonic Link2Cell KX-TG78 Bluetooth connection
Solution
I have upgraded the Xperia M (C1905) to Android v4.3 and now have a robust Bluetooth MAP (Message Access Profile) service.
Bluetooth MAP service now works on the Xperia M (C1905) with the Panasonic KX-TG78 land phone.
After pairing with the Panasonic Link2Cell KX-TG78 land phone, I'm then prompted to 'authorize' a MAP service.
You will probably still have to edit the Bluetooth /data configuration for Bluetooth to remove the blacklisting of Panasonic MAC OUI 00-08-F0
I did this as I have a phone with root access to the /data/misc folder.
When you re-connect the Bluetooth service after a second time the Bluetooth MAP service connects automatically.
There is a notification on the status bar which can not be removed which indicates the Bluetooth MAP service is active.
The notification states, - Bluetooth Message Access to "DECT KX-TG78"
This never appeared on the old Android 4.1.2 ROM where Bluetooth would pair successfully once, but not the second time unless you reset all Bluetooth /data/Misc configuration. This was unworkable using Android 4.1.2 ROM
In the old Android 4.1.2 you still got an audible txt alert notification on the land phone when Bluetooth was successfully paired on the first connection. However, you couldn't get the Bluetooth connection to re-connect on the second time after Bluetooth had been turned off and on again.
Summary
Using Release 15.4.A.1.9 Android 4.3 on an Xperia M (C1905), all Bluetooth services I have tested on a Panasonic DECT KX-78 home/land phone worked effectively.

[Q] Moto 360 can't connect to my lenovo phone

Hi guys,
the moto 360 doesnt connects to my phone. I hope someone knows a solution for this problem.
My situation:
The phone is a Lenovo S920 with chinese firmware. It has android 4.4.2 Vibe UI 2.0 and i flashed gapps-micro. the latest version of play services, google search and android wear are installed. Everything works perfect.
The website from google with the wear compatibility check works.
Pairing with the watch works also but it doesnt stay connected, just for a few milliseconds.
With other phones the watch is working and the bluetooth from my phone works with other devices, like speakers or computer.
For me it sounds there is a problem with the bluetooth. Is there a opperntunity to fix this. I'm wearing the watch since two weeks without any functionality. Well, it just does what a watch does, telling me the time

I fixes it. After I installed new firmware on my phone android wear asked for a permission to use bluetooth. But after any disconnection the pop up displays again. It doesnt remember my choice.

I have got a WiFi enabled ELM327 and it works without any glitch on this same unit.
Have you tried setting up the Bluetooth using the phone menu settings? Do not keep phone connected to unit while searching for OBD2 unit

I have the same problem.. I tried buying the bluetooth and the wifi dongle with 0 results.

Are you trying to run Torque (pro)?
Torque Pro works best with a USB connection

MIUI 11.0.3 Bluetooth connection problem

Dear All,
I have bought this phone 1 week ago but I have problem with the bluetooth connectivity. When I would like to connect the phone to a bluetooth car device the pairing code request dialog not shows up and because of this the pairing fails. Do you have any solution for this? With Redmi Note 4 (MIUI 11.0.2.) the car works well. I tried it with other car devices but there was the same problem.
Thank you in advance!!!!:fingers-crossed:

Try going to Settings-Apps-Manage apps-Bluetooth and Clear data-Clear all data. It helped me for some time but now Bluetooth problems appear again and I have to do it every time after answering the call while listening to music via Bluetooth.

Hi! try changing your AVRCP version from 1.4 to 1.6 in developer options

Thanks for reply! Unfortunately it does not work! The pairing request dialog window is still not popping up...

Maybe you need te change the bluetooth notification priority to high and maybe check permisions.allow it to show on home screen etc

Thank you for everyone! I found the problem! The app of my bluetooth watch caused the problem, after uninstalling it the bluetooth works again.

I face a similar problem with skoda car infotainment.
In my case pairing is successful but on the first call connection breaks. Even if connection is broken and car's infotainment starts seeking for a Bluetooth connection Redmi note 8 thinks it is still connected and it stucks there. when connection breaks a message pops up that reads something about AVRCP not supported and redmi note not responding
A have unpair both devices many times but same thing happens again and again.
I have to point that i came from a Redmi note 6 pro, where EVERYTHING regarding bluetooth connections and multiple connections were operated just fluently. I have redmi note 8 just 2 days
On redmi note 8 are always connected an amazfit stratos and a meizu ep51 handsfree and there are some other apps installed like mifit.
Do you thing that i should start first by unistalling all apps?

i unistalled amazfit app and it seemed that was getting better but i assume that phone it cannot deal with multiple bluetooth connections. Unforunately it cannot managed android auto (wired connection) and car infotaimnet (bluetooth connection). On the first call connection drops.
I flashed a custom ROM- based on China roms- but things didnt got better. Having both redmi not 6 pro (which handles all bluetooth connections just fine- even transfering active call via bluetooth headset to the car infotainment as soon as it establishes a bluetooth connection while i am getting into the car) and Redmi note 8 on developer options i copy all setting from Redmi note 6 pro to Redm note 8 but all issues are still there.
I wonder if it can be used the bluetooth app from the Redmi note 6 pro to the redmi note 8 but i dont have the knowledge to do it

I have the same problem. It sucks that redmi note 3 which i had before worked 100% ok...

All these issues make phone quite useless considering that everyone goes wirelessly. I wonder if this disappointing case is claimable from Xiaomi.

just noticed the same problem, both of my RN8pro bluetooth mac is 00:00:46:00:00:01 which is nonsense.
maybe you all got the same mac as mine, which is generic mac.

How can I check Bluetooth mac address ? Do I think there is something can be done?

Settings > about phone > all specs > status.
There's a bluetooth mac near the bottom.

I checked my Redmi note 8. It's seems normal, 28:16:7f:b5:65:2b is it?

MIUI 11 - Android 10 version?

The only workaround i found is to keep one connected bluetooth device at a time. So before i get into my car i have to disconnect bluetooth headphones and reconnect them after. Bluetooth management of Redmi note 8 is a big mess. I assume that is a phone's hardware problem its incapability to manage two or more bluetooth connections simultaneously.
I contacted Xiaomi customer care regarding bluetooth issues and i was finally asked to perfrom a test. I wonder how a test could resolve it

In the attached screenshot in developers options the max connected audio devices option is 2 but it's deactivated so i cannot changed it eg to 3. Could it be the solution to bluetooth connectivity issues? Is there any way to activate this option and change it?
