Bluetooth pairing and BLE

Hi anyone else having issues pairing to Ble devices... Eg heart rate monitor?
I am running CM12. 1.1 normal Bluetooth pairing doesn't see these devices.... I was starting to think p8000 not really Bluetooth 4 compliant....
But apps like Ble tool off play store allow me to see these devices and even display heart rate....
But many apps appear to need paired devices to work Eg Runtastic strava etc.... But I can't pair....
Any advice...?

Bluetooth and WIFI interference on Xiaomi Mi 6

Hi everybody,
since I bought my Xiaomi Mi 6 last year I am having the following problem:
If I am using WIFI and connect a bluetooth audio device the connection always lags drastically and it is not possible to listen to music properly.
I didn't have this issue on my LG G2 before and in addition, other people who use my WIFI in combination with the same bluetooth devices do not come across this problem.
Furthermore there is no such thing if I am using my computer to listen to music via bluetooth.
Is there anybody who has noticed the same problem and found a proper solution?
Thanks in advance!

Huawei/Honor - compatibility problem with car audio Kenwood BT305

Hi,
I have Honor 9 and now bought a car radio Kenwood BT305: https://www.kenwood.eu/car/receivers/all/KMM-BT305/
Pairing with phone is OK.. But I have some problems:
1. Sorting contacts with radio has no logic. The names are differently shuffled, not in alphabetical order.
2. When calling, only a number is displayed, without a name.
I tried other Huawei / Honor phones and the problem is the same. Samsung and Nokia phones working correct.
Can anyone help me? Does this have any solution?
Thx!!

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?

Note 8T bluetooth issues

My girlfriend has something called FreeStyle Libre 2 which is a device to monitor glucose (diabetes). This communicates via bluetooth to the phone if there is any problem. Alarms are disabled because it can't make a proper bluetooth communication with the phone.
When we bought it 2 months ago, it was working somehow, perhaps working the majority of the day and then at night (when you really need it), it stops working. I believe an update to MIUI made it works even less.
So now we have a new phone that doesn't really work for us.
Could a new rom / kernel make it better? Or the BT chip sucks? I read something about BT / wifi issues.
Thanks.
