bluetooth issues - Redmi Note 2 Q&A, Help & Troubleshooting

looks like Xiaomi made a change in the BT module in MIUI 8 (and maybe in 7.5)
with 7.2.3 my device worked fine with the car's BT kit. and after upgrade, there are problems (the disconnect button in the car kit doesn't disconnect the call)
any idea what was changed in the BT module?
other ideas?
thanks

Jabra 320 A2DP problems...

Hey people,
I tried connecting my Jabra320 up to my Touch HD the other day. The headset should support A2DP for stereo bluetooth, which worked with my old Touch Dual, however, whenever I try adding the headset to my HD I can only see the hands free profile.
Anyone had any problems with A2DP or any ideas how to fix this?
I was thinking about getting a Sony Ericsson headset, but don't want to commit to the investment until I know that I can use the A2DP profile...
I'm using Dutty's v2.5 rom and the v1.12 radio.
Same problem with new duttys roms. It shows me both wireless stereo and handsfree but when i try only to connect A2DP it disconnects. Worked fine on older duttys roms.
I have Jabra 620s

You're getting a little further than I - I domn't see the 'Wireless Stereo' option at-all. Well I believe Dutty is releasing a new ROM soon. Hopefully it'll be fixed then. If not I'll mention the problem when it comes out - hopefully Dutty or someone will find a fix.
Thanks though for confirming I'm not the only one with this problem!
Hope you guys has fixed your problem. if not, let me tell you how to fix it.
I had the same issue before. now it works.
1. make sure your headset is power off and delete the connection on your cellphone.
2. connect your charger to the headset for 4 seconds, then disconnect it.
3. repeat step2 4 times.
4. after that, your headset will be reset. then, reconnect to your cell phone and you will see wireless stereo function enabled.
What I have discovered on my A2DP headphones (Philips SHB7100) is that when I power them on it will automatically connect but only with wireless headset (phone calls only) functionality.
What I have to do is go to the touchflo settings tab, select Menu> Bluetooth Devices and disconnect then reconnect the headset. Once I do that it connects for both A2DP and phone calls.
I also have a Jabra "Dogtag" headset and it ALWAYS reconnects with both automatically unlike the Philips set, so I suspect this also has something to do with the headset itself and not just the OS/ROM.

[Q] Bluetooth Headset not pairing ICS LPQ

So my Jawbone Prime was connecting fine before I updated to ICS LPQ (was on GB LA4 before) and now it doesn't even show up on the devices list even when I try to re-pair or reset the headset.
I tried 2 different sets to no avail.
Anyone know of a solution?
Connects to A2DP BT Headset (Motorola) but only allows media audio to connect. Phone audio doesnt stick.
ICS has some compatibility issues with certain bluetooth devices.
GB my phone always paired with my car stereo and streamed music without any issues.
So far every ICS release, even official, has caused my phone to reboot after streaming music over BT for 10+ minutes.
Its pretty sad they dropped the ball here. GB worked fine, and they borked it.
Well I can connect my BT keyboard fine. I just tried my Motorola BT earphones which are A2DP and it connects but won't allow phone audio to go through the BT earphones. However Media does go through. At least it detects it.
It doesn't detect it at all on the Jawbone Prime (which is not A2DP).
Update:
I managed to connect my jawbone and actually have 2 phone calls on it. After that I had the phone in my pocket and when I checked maybe 15mins later it had frozen and I had to keep power pressed to shutdown/reboot.
It kind of matches Chakker3D's pattern of working then not working. It's like there's a memory leak in the bluetooth stack? maybe I'm just spitballing here.
What I know is that in GB whenever I deactivated BT it took a good 20-25secs. In ICS it's instant to turn off or on. In GB however there was 0 issues.
I just really hope Samsung addresses it. Or if we are lucky, a dev will rework a rom so this problem is gone.
But from what I can tell, very few are having this problem.

Another update:
Without any intervention on my part other than keeping on trying it finally discovered my BT headpiece. In fact it discovered both.
Now it's still not 100% perfect because it discovers it, connects and immediately disconnects. If I press a button on the headpiece while it connects then it stays connected and it hasn't restarted/locked the phone yet. I even connected my 2nd headset (another Prime) and it worked.
Keeping fingers crossed. Now I need to see what happens when I walk out of range and back in range.

AOKP 4.2.2 - Bluetooth Pairing

Hi all. Has anyone tried to pair with a car?
I'm trying to pair with a Kia Sorento. It's looks like it pairs OK and then shows connected but the car doesn't acknowledge that it is connected.
I'll continue to test but wanted to know if anyone else had success. I'll try with other bluetooth devices as well. Please post your experiences with Bluetooth.
Thanks for the ROM update and thanks for your responses.
Well, I've successfully paired and used several different bluetooth devices. Didn't think I had this many:
- bluetooth mouse
- bluetooth keyboard with built-in trackpad
- OBD II reader
- Music headset
I have a phone headset and my car. It looks like both of these pair but don't connect properly. The headset is for phone profile only. After pairing, clicking on it does nothing. Doesn't even try to pair. For my car, it pairs and I'm able to enter the pass-phrase/key but then it doesn't connect.
It looks like there is an issue connecting to devices that use the phone profile. When looking at the settings for the paired items, there is a profile for phone audio. It has a checkbox which is not checked and is disabled...cannot check it.
I'll post screen captures when I get a chance.
Thank you
It looks like the HFP (hands free protocol) is needed for using a headset on a mobile phone as in the case of a earpiece or to use a car as a hands free for a mobile phone as well.
It looks like Blues does not support HFP. There is mention of an oFono project that works with Blues to support HFP but no mention of Android support. I also found some mention of Blues adding that support. Maybe it's available and needs to be configured. Didn't dig too far into it and I'm not that familiar with these technologies.
Hopefully, one of the devs can follow up on this or another group has done it or figured out how to do it.
I'll keep looking and will post if/when I find anything.
FYI, Bluez just released a new version April 12th.
I found some configuration files in /system/etc/Bluetooth
The audio.conf file has several settings referring to headset and hfp. I tried some variations but no luck. Good news is that it looks like Bluez supports headset and hfp out of the box/built-in.
More testing needed.
I also read that after changing settings you will have to unpair and repair your device to pick up the change.
I wonder what the stock files have?
It looks like, ideally, there are other profiles that should be there to have a good experience. PBAP, phone book access protocol, is needed for transferring contacts, for example.
it fix on next release, but have reboot afte call =(

So my reboot after a call is related to bluetooth headset. Right?
Any ideas about overcoming this?

Amazfit Pace (1.3.6d-stock) cannoct connect any bluetooth headset

Hello XDA-Devs,
i bought a brand new Amazfit Pace (International) and updated firmware to latest stock. Setup was quite fine and watch paired with my Phone (Redmi Note 3 Pro) and Amazfit Watch App without any problems. I was also able to connect via MTP from Windows 10 PC and store some music on the watch.
Now i tried to connect my bluetooth headset (Bluetooth Bragi Dash Headphone) without any success. I put the Bragi Dash Headphone into pairing mode and in wacht BT menu it opens BT overview with blinking "Searching" indicator. After a while the blinking "Searching" indicator disappears and thats it. The Headphone does not show up. I also tried with a Bluetooth speaker with same result. Both, the Bragi Headphone and the bluetooth-speaker are working without any issues with my Phone, Windows tablets and other devices.
Any clue or same issue? Actually i like the design of the watch, but possibility to pair a bluetooth headset was a buying decision for me ..
thx and br

1. Make sure the BT devices aren't paired with any other devices before trying to pair with watch;
2. If BT on watch is working fine, you should stay connect if you go away from your phone about 10m (without barriers), if connection drops 30-50cm from phone then maybe you have a problem with the watch's BT (weak connection due to bad antennae or BT chip);
3. Put phone and any other device around in Airplane mode (or switch other BT devices off), do the same to watch, then enable only BT and try to pair again. There are some known cases of WiFi/BT interference.
If everything fails, maybe the phone/speaker simply aren't compatible if they pair with other devices. Watch should be able to list other BT devices nearby, if the list is always empty, looks like BT is damaged. Try an unpair (reset) and pair again with another phone and/or account on Amazfit app. Good luck.
Hello lfom, thanks for fast reply. I did a factory reset and it still does not work with my Bragi Headphone (150€) (https://support.bragi.com/hc/en-us/articles/115000132569-The-Headphone-Technical-Specifications)
But one good news, i tried with a very cheap bluedio BT-Headset (9€) and surprisingly this headset i could directly connect to my Amazfit Pace watch and works fine...
... so it seems there is some general incompatibility... maybe related to BT 4.0 A2DP version. As you see here http://www.phonemore.com/xiaomi-amazfit/specs/3497 the Amazfit Pace should support BT 4.0 A2DP. I assume the Bragi Headphone does handle the protocolls correctly (had never any issues with them) and they are premium product... so unfortunately it seems we have to wait for fix fom Amazfit side.
Anyone else can report incompatible BT devices? Or maybe anyone else out there tried to connect a Bragi product?
Thx and br
Probably it cannot be fixed by Huami, as the the limitation is the hardware used in Pace (4.0BLE). I have read somewhere that Stratos uses a different BT chip and supports higher version, not sure if 4.1 or 4.2. There is a list of known compatible and incompatible devices in a Facebook group:
https://www.facebook.com/groups/HuamiAmazfit.Pace.Smartwarch/permalink/344737925947591/
Thx lfom, i joined the group and seems that Bragi The Headphone does not work in general (others report that too). Sad that a standard protocol like bluetooth still seems to have compatabiliy issues. Have to live with it and use different BT-headphone. Thx for your help
Hi... my Kaidi headset will not pair Amazfit as well. I can pair Amazfit with iPhone and can pair Kaidi headset with iPhone but never Amazfit with Kaidi. Sad...

Bluetooth issues - connected (no media)

i am facing this issue when i connect my bluetooth headfone BlueAnt it shows as connected but with no media..in setting i tried to check uncheck media option and reconnected and even restarted the device but to no success
Any guidance is appreciated
i tried it on Oreo Roms as well as EUI both giving
this issue
Heyyo, reading up on it? It could be related to A2DP.
I'd recommend going to other Bluetooth devices your BlueAnt is paired with and disable media on them and then try pairing to your Le Max 2 again as it seems to be more of an issue with the BlueAnt and other devices causing issues. I've seen on Google that others note for devices with A2DP that Bluetooth car audio tends to be the main culprit.
I tried the same device when it was on stock chinese 13s rom and then it was
working properly...
i then flash different roms ... and then when i settled down for the one
i liked .. this issue arrived... BlueAnt headfone has no issue with my MATE 8, only
it shows no media for a few seconds and then it disappears and then i can
normally use it.
Will try your advice
