[Q] Chaning Bluetooth ID - myTouch 4G Q&A, Help & Troubleshooting

I have three MT4G in the family and last year when I rooted the devices I had trouble with the second one and used some files from the first phone to restore and then rooted. Now when I try to used the Bluetooth to connect with my car both phones show up as the same. I can go into the BT properties in each phone and give them unique names that show up on the car but when I turn the BT off on phone and turn it on on the second the name from the first changes to the name from the second. In my car I can see a list of all the devices that are paired and if one is turned off it does not leave the list it just turns gray.
So I suspect the issue is with the BT radio ID (or something like that) and I ended up with the same ID on both phones when I crosses some of the files. Now the trouble is I don't know at point I did this and how to somehow reverse it.
I hope this makes sense.
Thanks,
Aleem

Bluetooth Issues

Hi, sorry if this has been discussed somewhere else, but I haven't seen it.
I'm on my second M5k (the first one had serious radio issues), this one has bluetooth problems.
I've paired it with my Parrot car kit (which has always worked fine), but recently the car asks me to pair a device everytime its powered on. Likewise, I've just paired a BT GPS & it's connecting but not really seeing the device. In the BT manager, both devices now have a ? icon on the left rather than a headset etc.
Any ideas whats going on?
Thanks
Check on your outgoing port settings in bluetooth settings, if there is a tick in the secure connection, uncheck it and see if that works.
I had similar issue with bt gps reciever
Nope, not ticked.
On a side note, its been sat next to me for an hour with wifi on, connected to the pc & its just shut down with 52% battery left. When this thing doesnt wanna play, it really is the biggest waste of money i've ever had (course, for that 5 mins that it works properly its the greatest thing i've ever spent my money on).
sorry, thats the extent of my knowledge ... just a newbie
best of luck and keep the faith !
when i have a hard reset my paired devices disconfigured only

[Q] Bluetooth and Cars

There are some very old threads about this - but this is now, pretty certainly, a general stock android 4.3/4 problem with "older" car hands-free systems. My kit is a Galaxy Note with OmniROM right up to date. My car is an Opel/Vauxhall Zaphira with a Navi 900 onboard computer. However there are threads on many android forums complaining of the same symptoms for "pure" stock 4.3/4 devices (e.g. the Nexus range, including the Samsung Galaxy Nexus) and a variety of cars, and all describing the same workaround (and a few lamenting that Google haven't been very responsive in addressing the problem). The symptoms and workaround are:
The car recognizes and "partially" pairs with the phone
However, the contacts list and call lists are empty and the phone cannot be controlled from the car, neither for incoming calls nor for outgoing calls (dialing from the car interface always gives a failed message, while trying to receive or hangup from the interface just plain fails).
Calls using the phone work, and show up on the car interface, always as "Unknown" (not surprisingly - it doesn't have the contacts list)
HOWEVER if, after this "partial" pairing up, I make a 30-45 second call using just the phone itself, then, after the call has terminated, contacts and call lists are properly available through the car interface and the phone can be fully controlled from that interface (and, of course, the FIRST time this happens, I get the notification on the phone telling me the car wants this information, which, of course, I confirm)
A workaround like that can be scripted with something like "Tasker" and using, say, my voice mail number (with my provider here in France, plain fake number calls don't stay online long enough for the above to work).
But does ANYONE have any idea where to start looking for the root cause and possible solutions, or have any theories on those points?
EDIT:
Just to be clear - the workaround "make a call from the phone" trick has to be done every time the phone and car reconnect, not just the first time.
Had this happen in my ford the other day and it's sync system.
The fix for me was a not so visible notification upon establishing the Bluetooth pairing in the notification tray asking if I wanted to allow for my phonebook to be downloaded. Clicked yes and everything set up as normal.

I got that notification AFTER I had done the "make a call from the phone" trick, not before.
I should also point out that the "make a call from the phone" trick has to be done every time I want to reconnect to the phone to the car (while the notification only appeared the first time I did the trick - because subsequently the phone and the car "trust" each other).
Aside from maybe unpairing and trying to set it up again which I am certain something you've probably already tried; have you checked the cars firmware?
Could also try resetting your Vauxhall's system as well in case there is a gremlin in there causing a hang up with the sync.
Again with Fords sync I have had to do it a few times over the years when the systems been misbehaving with the Bluetooth and it fixed it.

Indeed I did the resets. And yes, possibly, an upgrade of firmware MIGHT fix it, but these problems don't occur with Android 4.1.n (or, I, believe 4.2.n).
I've logged a bug with the OminROM developers, but would like some pointers so I myself can start looking at solutions and fixes.
Hmm... Unfortunately I don't know who to assign that JIRA bug to.
Problem is - none of us own vehicle headunits that we can reproduce/test this problem on. I used to have a Sony MEX-BT2500 (technically I still do...) but since I sold my old convertible it just sits and collects dust.
I would agree that this will be a difficult one to find. It reminds me of working with 802.11b/g with it's dozens of "pre-draft" variants that just didn't interoperate properly.
If you wanted to dig into this yourself, the first place I'd look is https://github.com/omnirom/android_external_bluetooth_bluedroid and its upstream and parallel variants. That is the code that generally handles the upper-level Bluetooth management functions.
Edit -- Also worth looking at https://source.android.com/devices/bluetooth.html if you want an overview of how Android implements Bluetooth.
The comments on commits there might also be worth reading through. For example
https://github.com/omnirom/android_...mmit/73ce8ab2ddd30cab6499d0062c46b3a16f9130a9
Fact is however, that the use of SDP features value for peer_features
is new since Android 4.2 and breaks existing good behavior on a BMW
2005/E46 car kit (navi professional). This kit never asks for AT+CHLD
and never via AT commands suggests it supports 3WAY (although it seems
to have the flag set via SDP).​
Not the same issue, but there might be clues of that nature in the commit messages.

[Q] android bluetooth paired device origin

I need help finding out where a bluetooth connection originated from. I woke up this morning with a new paired bluetooth connection even though my bluetooth is turned off. Is this even possible?
The name is BLE_nuvi #1234567890 (the numbers are different). After researching the name, I am assuming BLE stands for bluetooth low energy. When I researched nuvi, it looks like its a Garmin model. But I know you can name any bluetooth device whatever you want so this may be irrelevant.
Since I do not have a Garmin, anyone have a theory as to how this pairing was made?
With the exception of me sleepwalking, driving to a store and purchasing a Garmin in the middle of the night, does this mean I got hacked?
I have a Verizon Galaxy S5.

After researching a bit more I found out that there is a setting in Developer mode that allows you to turn on "Bluetooth HCI snoop log". Since this wasn't turned on, does anyone else know of any other logs that record when a bluetooth pair was made and/or with what device? I also found out that in order to read these log files, you can use a program called wireshark.

Bluetooth Connection Problems -- Please help

Hello everyone, I bought a new 2015 Jeep Cherokee Trailhawk, it has the 8.4N Uconnect system installed.
I can connect with bluetooth with any other devices, and everything works properly....EXCEPT my phone which is a:
Samsung Galaxy S4
Branded by Fido in Canada
It is rooted, still using the default rom that came with it, but I'm running Nova Settings instead of Touchwiz
SGH-I337M
Android 4.4.2
-----------------------------------------------------------------------------------------------------------------------------------------------
In my car, I goto Phone/Bluetooth settings, have option to change PIN to anything I like but left it at '0000'
On my phone I goto Bluetooth, turn it on, make it visible, hit scan......it finds UCONNECT
I press on it to connect and THEN.......
On the car:
if it is the first time trying since reboot, you can see the passcode show up (six digits - 3 digits a space and then 3 more) and an ACCEPT button. This immediately disappears and it says 'There was a problem connecting with your bluetooth device. Please try again'
If it is not the first attempt after a reboot of phone, it just blinks that first screen showing the weird seperated 6 digit pin and immediatley goes to the error messager.
On the phone:
When it finds UCONNECT and u choose it, a message pops up saying to confirm the passkey and press OK or CANCEL.
It always shows a random 6 digit number.
At the same time, a system message appears for a couple seconds at the bottom of the phone that says 'Incorrect PIN or Passkey. Please try again'
Pressing OK or CANCEL just returns you to the bluetooth scanning screen which shows UCONNECT as an option.
If i try to set the pin on the car with what was shown in the phone, it doesn't work as each attempt to connect generates a random pin on the phone.
I have restarted phone, car etc. Reset car radio completely. Removed all devices remembered on the phones bluetooth. Checked with UConnect support that my phone is compatible -- they say that it might be that Fido in Canada has done something to the phone to prevent it to connect to cars, as it works fine with Verizon/At&T/ and apparently people on Rogers in Canada with S4 works too.
I have commented out the blacklist entries on the phone in /etc/bluetooth/auto_pair_devlist.conf - no change
I have removed all files in /etc/bluetooth - no change
Other phones connect to Uconnect with no problems.
My phone connect to my TV and a bluetooth receiver connected to my home stereo and a second TV different brand no problems.
This is my main phone, also my new car. It really sucks that I cannot get it to pair. Fido, Uconnect support can't help - they have never seen this issue before.
I don't understand why the car shows a pin of six digits with the space between the two groups of 3.
Also, why the phone says incorrect pin or passkey.
PLEASE HELP!! I am going crazy over this!
I really don't want to, but if there is no fix, I will have to backup everything, format the phone, install perhaps a Verizon or something build of Android and then try to connect with that (hoping it has no issues with phone/data use with Fido network over here)
Updated info
I just tested with anothers car....
2009 Nissan Rogue...works fine (is used as an audio device only...no phonebook etc features)
Also tested with an Iphone 5 to my Jeep and that phone connects fine.
I tried using an app called 'Bluetooth Fix Repair' from the app store. It gives an error at startup:
"Sorry this application cannot find your bluetooth setup folder on this device"
Can this be the issue?
The bluetooth folder I was working with in the OP was on the phone at etc/bluetooth
Should I have another one somewhere...maybe missing or corrupted?
Any help!?! Cannot find anyone else with this same issue here (xda) or on google etc.

Bluetooth question

I am coming from a long history of HTC use and so I apologise if this question has an obvious answer.
Previously, if I wanted to connect to my bluetooth in the car (previously paired with), I would just hit the bluetooth button in quick settings to turn it on and that was it, just like connecting to wifi.
If I do this on my S7E, I then get another screen popping up that tells me my device is visible to others and lists previously paired devices for me to select from, and then I have push the back button to leave that screen?
Is there a simpler way as I used to do on my HTC?
cheers
C.
PS - I am sure this will be the first of a number of questions as I get used to TouchWiz and Marshmallow......Sorry.....

Have you ever *paired* your new phone with your car?
I've only had two cars with BT in them, but in both cases the car and phone had to be paired before they would work together.
Once that was done then it would work as you expect.
Specifics of getting your *car* into pairing mode I can't help with, but once you do that you should be able to select it while scanning from the phone (as you've seen already the phone will list devices it finds) and you can finish walking through the pairing.

Oh yes, it was paired with the bluetooth fine (its actually a visor BT device, not the car itself), and when I turn on the BT it shows up on the list of previously paired devices)
Don't have to make it a trusted device for it to auto-pair?
Why turn Bluetooth off at all?
Just leave it on.

Dave

Nope, just had to be paired.
Trusted Device brings in the Smart Lock stuff, which enables the option of having your phone NOT authenticate you (pattern/pin/finger/passwd) when connected.
For example, I have my car bluetooth set as a trusted device so that when I'm driving I don't get any identity challenge to use the phone (like for navigation), the screen will just come on as requested.
Smart lock is blocked by my exchange administrator as I get my work emails on my phone.
I turn the Bluetooth on the phone off because I don't turn the one in the car off and it's just outside the house and will stay connected.
