[Q] Asus Memopad HD 7 572C K007 WiFi Bluetooth interference

Hi all,
I have bought this tablet recently. One thing that does not seem to work, is the simultaneous use of Wi-Fi and Bluetooth. When I stream a radio station, it works fine until I connect to my Bluetooth speaker. Then the app loses WiFi connection all the time, and has to reconnect all the time.
I tried other apps, all behave the same. When I use my Acer tablet (same app, same location, same network, same speaker, same radio station etc. etc. ) everything works perfect, so the Asus seems the problem here.
I narrowed the problem down to interference between Bluetooth and WiFi: when I do a speedtest, WiFi speed drops from around 35 Mbps to 5 Mbps at exactly the moment sound starts coming out og the bluetooth speaker.
Is this a known issue, , anyone experience this, how couldthis be solved?
Thanks.

music lag (freezing) through bluetooth headset

Hello to everybody!
I am currently on the latest Viper rom (7.1.2) with soda kernel b1.2.1 installed. I've tried different ROMs (miui 9.2.2.0, latest developer rom, latest Pixel Experience, latest AEX mod, AOSP by jdc and some others) and always face the same issue.
I have music lag while listening it through bluetooth headset (music freezing). I've tried QCY QY8, 1more ibfree, JBL T110bt - and I always have the same problem. Most commonly music starts to lag while I use the phone to surf the Net via Wi-Fi, so it's like Wi-Fi interrupts Bluetooth connection. I've tried 4 different routers - it's all the same. But even if I am listening to music being not connected to Wi-Fi, music still lags 1-2 times every 3 minutes in average (and sometimes even more often). I noticed that it most commonly lags when I unblock the phone, so maybe it's something like lack of phone resources used on bluetooth connection? But anyway most commonly music lags when I use BT and Wi-Fi at the same time. It's very uncomfortable to use Youtube through the bt headset
I've already tried switching to other governors in KA, increased buffer parameter in Poweramp - it doesn't have any effect. Of course I made clean install of the Roms (including Miflash and format data). I tried firmwares 7.9.22 and the latest one.
Can you please help me to fix it somehow? Or maybe mi5 is just not good for BT headsets? I tried that headsets with lg g5 and xiaomi mipad - no problems.
Thanks in advance!

did you update your firmware?

Yes, except for 7.9.22, I've tried all January firmwares. I am currently using the latest one (8.2.2.), but it seems to have no effect

Bluetooth & WiFi Issues

Afternoon all,
I have the 512GB US Unlocked Note 9, and I have noticed two problems with the phone:
1.. On WiFi at my home (UBNT Access Points running latest firmware/software) I observe very poor WiFi performance on 802.11AC/5Ghz radio. If I switch to the 802.11N/2.4Ghz radio in the same AP, I get near wireline speeds when running a speedtest (about 175 down and 7 up). On 5Ghz, I barely get 7-10 down. No other WiFi devices have this issue.
2. Using Bluetooth audio in my truck (Dodge RAM with UConnect running latest firmware) I get audio dropouts/stuttering of about 1-2 seconds every few seconds, but this only occurs about 50% of the time. Sometimes it works flawlessly. I have no BT audio issues whatsoever when I pair my iPhone XR to this stereo.
Is anyone else having these sorts of wireless issues with their Note 9? The cellular/LTE speeds appear to be performing quite well and is very fast in an area with a good signal.
Thanks!

Very bad Bluetooth LDAC connection

Hi guys,
is anyone else using Bluetooth earphones with LDAC?
I have some 1MORE triple driver earphones and the connection is very bad.
At first I thought that problem are my 1MORE but I tried them with Pixel 3 device and had no same problems.
Is this a general problem or could it get fixed with update or another custom ROM?

I'm using Sony WH-1000XM2 headphone with LDAC and Xiaomi.eu ROM. The connection has been very stable for me, with no noticeable drops in quality and no drops in connection. I also had no problems on stock MIUI 10 either.

I can speak the same for XM3

Likewise no issues (aside ldac typical high battery drain) with fiio btr3, Sony wh-1000xm2 and wi-1000x

Hmm thank you all guys so far.
I tried the same headphones with Google Pixel 3 and had more or less no issues. Now it sounds that my device could be the reason? But it is just a software thing, aint it?

Bluetooth audio dropping out with Hotspot active

I just gone my Pixel 5 rooted and set up, but I've noticed annoying audio drops fairly regularly while having the hotspot on with not much going through it. Has anyone else noticed this, and is there a solution?

Nobody else noticed this issue? There seems to be shared bandwidth between the wifi and bluetooth. Fairly common for them to be on the same chip for sure but it's pretty unusable if I have tether active. Just got some new headphones that use ldac and the bandwidth requirement is so high it chokes immediately and is just unbearable garbage.
Any chance there might be a fix or is this hardware? It might have to do with using 2.4Ghz for tether. (Older devices)

BT and Wifi both operate in the 2.4ghz range.
See if tethering to 5ghz solves the problem.
My guess is that it's related to all that data transmission on two technologies that share a similar spectrum.
Could also be power consumption, being that this is not a flagship processor.

If rooted with a non stock firmware all bets are off... the firmware controls nearly all aspects of the chipsets programmable operation.
