Very short Bluetooth range with BT 5.0 Audio Receiver - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Just got my Ugreen CM110 bluetooth 5.0 receiver to use with my 9T with Eu miui 10 rom i believe. works great, except that the range is a joke.
started using normally and got skipping, pauses, artifacts in audio while walking with it. then realized that if i put both phone and receiver in the back pocket it works fine. if i put the receiver on the front pocket, the problems appear.
basically, my body in the middle is enough to disrupt the transmission.
tried tons of combinations of codecs/profiles etc, from the developer options about bluetooth audio, battery saving options, higher priority in player applications, nothing helped.
any tips for possible fixes?
thanks in advance.

Bluetooth Car Quality

Anyone else having horrible quality (static, brief silences) when connected to Bluetooth? Also it seems like if the screen is off and the song switches, the data doesn't get transmitted. I've tried several music apps and all the same so I'm assuming it's a firmware issue. Rebooting the phone, unpairing, adjusting equalizer for sound quality. Nothing.

No problem here, no disruptions, or Bluetooth range problems unlike note 2 that I had before. In the action memo, do you have a pin symbol, to pin memos to desktop? I saw it in numerous reviews but it is absent on my n910c
My Bluetooth keeps unpairing after I pair it. When I get back in car it says pairing failed.

No problems or quality issues with car bluetooth here.
Yes, I have exactly the same issue. SM-910U, no root, Spark NZ version with pretty much everything default.
I can't get a reliable Bluetooth A2DP connection to my car stereo (and it worked perfectly with my S4)... It will work mostly, but experiences lots of dropouts. Range isn't an issue - it happens even when being held 10cm away from the head unit. It also happens in or out of the case, and either being charged or on battery.

Really, really poor bluetooth audio quality?

On my G6, I have really terrible audio quality over Bluetooth connections, I've had two separate G6s, of different colors, received weeks apart, and they both suck for Bluetooth audio, especially my Sony car stereo, and LG Tone Free... can anybody else report on their experience? Does your LS993 sound awful on your Bluetooth devices?
Have a fairly new G6 bluetooth og Bose earpiece working very well, also on 2010 F150 pick up and 2012 Buick no audio issues. Audio has been fine so far.
Mine also is pretty poor. The volume level is about half the level of the satellite radio or fm stations in my car
Hello all.
I had G2 in the past and I use to listen music in my car, using Bluetooth connection to Pioneer head unit. I have Spotify premium account and I have my Playlist downloaded with the best quality. However once I got G6 a week ago I noticed that audio quality from the g6 with the same songs, same Playlist, same Spotify account, is not as good as it was with g2. So I did a short research and found a thread in the net where people reported the same problem.
A guy from the thread suggested to disconnect all other Bluetooth devices from the phone (like smart watch or band) and actually that solved my problem. I have MiBand2. Once I disconnected it the audio quality became as good as before.
So guys, if you have a smart watch, try to remove it and check the quality again. I hope that helps.
I went a couple of months with no issues on my Kia Optima, then suddenly, I started getting really bad aliasing on the highs. As said above, I turned off my Huwaei watch and the sound was normal again. After a bit, I turned my watch back on, and it remained fine.
I had it happen once again many weeks later; and again, a quick off - wait - on, cycle with the watch fixed it. So whatever it is, seems to be a bandwith allocation issue with the bluetooth software. From March '17 thorugh almost Sept '17 and I've only had to do this twice? I think I can live with this.
Hey heres something for you to try..
Download WiFi Scanner from App Store.. Look at your 2.4ghz networks.. then keep in mind your cordless phones, IP Cams, Walkie Talkies, baby monitors in your area.. You may be a victim of signal interference.
Bluetooth operates on the 2.4ghz spectrum along with a TON of other devices now available.
Your sony stereo may be the culprit.. if is an aftermarket "Xplod" deck
Im an audiophile, and my G6 runs better than my Samsungs.. (also no issues with the "preventative volume warning"
What you also may have is an app that is causing the volume to lower...
For example.. when i stream the music player with the stock app, sometimes Snapchat notification sounds cause the rest of the volume to be lower..
Google Maps is another one that can hijack the sound but you can control in settings.
For using music try a different app ( i use Maple Player) and it works great ..
Based on your experiences i think its something outside causing the problem to be honest. but thats ALOT of trial and error to deal with.. if worse comes to worse- you can always get an aux jack bluetooth adapter for your car stereo if it IS the stereos bluetooth receiver .

Erisin Es5060pb Head Unit Brief review and questions

I have posted questions about getting the unit on another forum but thought I'd post my experience, findings and also any questions raised to both help others and maybe get answers and help.
I went with the Erisin Es5060pb. Its the best spec I could find. Runs full android 6.0. Octa core processor. 2gb ram. 32gb storage.
Overall it went in much easier than i thought, simply plugging into the standard connector. We wired the included ext mic and routed it close to my head in the drivers seat. Routed the gps antenna close to the windscreen. I also connected the rear usb and put through a hole in the glove box which I connected the separately bought 3g dongle (might eventually just use wifi tethering from my phone) and that works well.
The amount of things it does are fantastic. Dvds, cds, usb thumb drives for both music and videos, and the same for micro sd. Google maps work ok, see below, as does youtube.
Issues -
1) The radio sounded terrible at first and needed a lot of tweeking in the equilizer app. Much better now (still not great though) but oddly is a little better with music played from files. I can't find an app that actually uses the FM antenna to see if it's better. It is also odd that any app's equilizer such as Pi Music player effects only that app and the radio is only affected by the inbuilt equilizer.
2)The fader thinks I'm in left hand drive so doesn't sound right if changed to only driver. Also when moved to only rear speakers it also still plays in the front centre, only turning off the front sides
3)When playing audio /video while accessing Internet via either wifi or data, (such as a YouTube video) there is low volume interference in the background. After a while this stopped but was annoying.
4)Due to having the 'Loud' option enabled in the inbuilt equilizer app which improved sound not just volume, it is only for music such as the radio, all other sounds are much lower. This means that if i have google maps on while playing the radio, the Google maps voice is way too low. By turning the volume up it increases but so does the radio which then gets too high.
5) due to all the messing with audio i have started to realise that i havent got a clue how to get the best out of an equilizer. i prefer the 'pop' type config of a higher setting on the middle sliders and a bit lower either side but i just cant get it right. any suggestions?
Hopefully this helps others and if anyone can help with any thoughts on the issues , I'd appreciate the help

anyone?

I have a lot of problems with this device, too. I'm using the custom rom from Malaysk.
1. FM signal and sound quality are terrible. I think there is no way to optimize.
2. If I'm connecting an usb-device while music is playing, music begins to stutter for a little time until the usb-device is loaded.
3. Bluetooth streaming quality is very poor! This was the reason why I had installed spotify directly on the unit.
4. Bluetooth pairs only every second time of unit boot to my mobile phone. Sometimes you have to connect manually...
5. Wifi connections sometimes can't be established although strong signal is available.
6. By using a 3G dongle for mobile internet, the unit freezes sometimes so you have to reboot it... I think this is caused by changing the cellular power of the dongle (3G/2G, 2G needs more power)
Im afraid i haven't had any of those issues. My sound issue was sorted by removing the 7th speaker that should have only been used for voice like factory sat nav.

Samsung S8 Crackling Bluetooth audio and Bluetooth Codecs

Hi Guys.
I've seen a number of posts on this subject so here's my story and my experience thus far.
I've been using an iPhone 7 since it came out. I've been very happy playing music in my car (Fiesta with SYNC2 system) all this time. My significant other has been using an S8 for some time, and her music always sounded 'crackly' (for lack of a better word) in the car. I thought this was just her Spotify or something.
2 Days ago I bought my own S8 and I had exactly the same issue.
Now from some research I've been able to deduce that this is down to the Bluetooth Codec the phone uses. I changed mine to aptX yesterday and the music quality was great. Didn't sound like a 200KB MP3 downloaded in the early 2000's anymore.
However...
Last night I had to reboot my phone for reasons, and the developer options reset completely, which I believe is normal behavior. But now I can't set my Bluetooth Codec anymore? I change it, the moment I close the menu, it reverts back to SBC. I tried this with Bluetooth off, Bluetooth on and not connected, Bluetooth on and connected, no joy. It keeps reverting. Same goes for all the other Bluetooth settings (i.e bitrate).
So gentleman I ask you humbly, wtf? Why does the settings not stick and is this normal behavior? Is there a way I can force it to use AAC or aptX once more? I really have come to enjoy this phone but playing music in my car is a very very big factor and since AUX and USB (can't seem to play Apple Music/Google Music via USB) isn't an option, I'm stuck with Bluetooth.
Thanks in advance,
Have you made sure dual audio is disabled???
If not, go to Bluetooth, turn it on, hit the tripple dots in the top right and tap on "Dual Audio"
Make sure it's off and now try changing to AptX or whatever codec works best for you.
Disable / re-enable Buetooth and see if it sticks. (Try rebooting too)
Also, Bluetooth codecs will automatically change if the device you're connecting to doesn't support your choice of codec.
Keep me posted

Hi Corey,
Thanks for the response. Unfortunately, the above didn't work Dual audio was disabled, I enabled it and disabled it again. I tried changing the codec and bit rate but the result is the same, the moment I close the menu or turn on Bluetooth, it reverts back to SBC and Best Effort bitrate. I should mention that when I turn on the Bluetooth, it doesn't connect to anything, the only paired device at this point is my car.
Interestingly enough, if I don't close the menu but just hit the middle button, the settings will stay as is and the audio is great. What I haven't tried yet is closing the menu after a 'good' connection is made to the car. It may be that the setting sticks but the menu says otherwise. But I can definitely confirm that if I close the menu and then connect, the audio is garbage.
As for the compatibility of the car's Bluetooth, well it's a Ford SYNC2 system which from what I can see is actually quite basic. I am starting to this the problem isn't as much the codec, but rather the bitrate at which the phone is playing/sending music across the Bluetooth.

I'm not gonna' lie, I'm not very impressed by the Bluetooth on the S8... or Bluetooth in general.
It's lousy most of the time, mine always distorts and especially around emergency vehicles... (Could be interference from their coms???)
If possible, just stick to good 'ol copper wire
I can't imagine wireless audio not ever being interfered with and will always stay wired.
Also, try a music app called Poweramp.
It has many settings involving latency etc. It has a trial for 2 weeks and is worth EVERY penny if you decide to buy IMHO.
Try the build version first, if that doesn't have settings that you need, try the alpha version.
It has lots of latency settings etc
I'm guessing higher latency = better results as it has more time to be pushed over BT before the sound is reproduced.
I'm probably wrong though.
Can't beat lots of settings tho aye.

Morning Corey,
Yeah so my situation at the moment is to have my old iPhone in the car at all times as a glorified bluetooth player. I've also gone out and bought an auxiliary cable for when the iPhone's battery dies on me (happens more often than one would think). And to have a charger for the iPhone, charger for the Samsung and aux cable for the Samsung all plugged in becomes really messy.
It must be something to do with the Bluetooth 5 feature. I don't know what version the iPhone is (cba to check) but it works like a dream.
Wish we had some form of backwards compatibility or a feature to force an older version with Samsung. Just sucks buying a phone which is really not cheap in ZA just to have the music sound like a 300kb MP3 played on Winamp with the treble bars turned up all the way.
I'll try out the app you suggested mate, thanks!

No worries and if you are referring to a USB cigarette lighter charger/USB charger then try the multi-cables.
Try one of these: https://www.amazon.co.uk/Poweradd-L...coding=UTF8&psc=1&refRID=59QBSADVWM0NKGZGTQ4K

car bluetooth problem

i have a 2013 Toyota Yaris with the manufacturer stereo system.
audio is a bit skippy, but at the end it works (maybe a buffer issue) - but when i try to call someone it always sounds like the oerson talking to me is underwater.
very bad sound quality.
does anyone know how to fix this?
(i've tried: clearing cache, turning off the wifi, clearing data from bluetooth, disconnecting and reconnecting)
thank you!
I have the issue with the audio skipping. It seems to only happen when certain conditions occur, like when I turn the car off for a short period of time. It's a Mazda 3 and the issue happens on both my wife's car (2014) and mine (2017).
I don't notice it that often anymore because I use Android Auto and regular audio seems to go out USB in that setup. I don't have issues with call quality.
my problem keeps going.
in rare situations i can talk, and sometimes the audio actually plays fine
it may be a buffering issue of sorts?
i tried using developer options to change USB settings but that doesnt seeem to stick for some reason (aways reverts back), and i thought that myabe the "best effort" option was a bad choice - but i cant check...
Just to check i tried to stream from both Spotify and YouTube and both works fine with Renault Clio's MediaNav system.
(approx half hour each)
Hi everybody, I think i'm facing the same issue.
I create a bug report on the official MIUI website. It could be great if you can Confirm the bug on the following page.
You just have to connect with your MI account on the website and click on Confirm. It's the only way to be more visible to developpers.

Thank you very much
Tom.
So there is no solution till now??... I cant have a conversation in my car !!! Only music plays well. Its a Toyota RAV4
Any help?
