Bluetooth and HotSpot problem after Phone update to Android 8.1 - MTCD Android Head Units General

I have an MTCD PX5 unit using SVA ROM Android 6 and I have been using it with my Phone for calling over Bluetooth. I am also using WiFi HotSpot on the phone to share the Internet Connection.
After the phone has been updated to 8.1 (it's a Nokia 6) Bluetooth only works well (not perfectly) if the HotSpot function is disabled. When enabled, the bluetooth connection is lost after I make the first call (which fails actually, the sound moves back and forth between the unit and the phone).
Does anyone else use a phone updated to 8.1?
Thanks.

[Q] Mildwild 5.0 - Bluetooth issue

I'm using Mildwild 5.0 as daily ROM. I noticed that even though bluetooth is on, the phone does not connect to the remote audio device.
The pairing process is successful, however the connection is not automatic.
I need to manually connect the phone to the device using the Wireless settings menu.
Did anybody notice the same behavior?

i have the same issue, i could not transfer photos to another device through bluetooth, haven't checked a handsfree because i don't have one, but there is a bluetooth issue
I had used this ROM for couple days and I don't have this issue. Maybe try with MV 14.

I had a similar problem with this ROM and my car's audio/phone system. I suspect the problem was on the side of my car's bluetooth, because after erasing the link on car's side, I was able to setup it again, successfully.

I'm still experiencing the same issue with MW 14.
My car kit is most probably a BT 1.1 device.
Here's the relevant logcat information
Code:
E/BluetoothEventLoop.cpp(167): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1081/hci0/dev_00_14_09_13_51_33

[SOLUTION] Fix for 4.3: unable to power on WiFi and/or Bluetooth

I update my Samsung Galaxy Note 2 to Android 4.3. Sometimes the WiFi goes off without reason and it was not possible to switch on WiFi or Bluetooth. I found that this was caused by two of my Bluetooth devices. I had to go outside out of range of Bluetooth devices and then switch Bluetooth on and then delete pairing I had in the phone (since previous Android 4.1.2 version). Hope it helps somebody as I'm not alone as I saw when digging through Internet forums.
BTW: WiFi & Bluetooth share the same chip, so it seems like a bug in Bluetooth kernel driver or library that manage Bluetooth connections. THERE IS NO NEED TO FLASH ANYTHING!

Automatic bluetooth connection with HFP

Hello, I have some problems with the bluetooth connection to my Seat Leon (2016). Pairing worked fine but once I return to my car only the A2DP profile gets connected. In the car menu media control is working correctly but the phone part is shown as disconnected. The bluetooth connection state in the phone settings shows "connected (no phone)" then.
To fix this I have to manually disconnect and reconnect bluetooth on the phone - afterwards everything is working as expected. This is very annoying though and I had no such issues with my previous Nexus 6P (stock 8.1).
Any suggestions? If there is no solution I try to fix this with tasker, however I'd clearly prefer a "native" solution.
Thanks in advance.
Seems like it's working with the app Bluetooth Auto Connect, will test it more intensively in the next days. But I'm still wondering why it's not working out of the box...

Zlink v. 4.0.8

I can't get wireless android auto working on my PX6 MAX 10.
I have the Bluetooth connected to my phone and my phone connected to the head unit's hotspot but nothing happens.
Works over wired though...

zlink bluetooth connection

Helo.
I have chinese android navigation mcwauto 8001 for Audi Q5 8R.
My issue is lack of bluetooth connection when I am using Zlink app.
I am able to connect phone with naviagation via bluetooth, but when I establish android auto connection using USB port the bluetooth connection is lost.
Because of that I am not able to make a call using android navigation/zlink. The call is make by phone speaker instead of bluetooth (android navigation).
What is more I tried several times to force bluetooth connection with my phone when I am using wired android auto, but even I am able to connect bluetooth the connection is lost every time I am trying to call.
When I call I have the message "you are not connected with bluetooth"
My zlink app is 3.9.31 - according to my navigation this is the current version of zlink. I found few newest upgrades but I am not able to install it. Few of them stop installing in about 80%, the rest even installed properly not working, the app just stop responding, and the hard reset are required.
Does any of you know solution for my problem?
The red android auto icon (two triangles) on my navigation are showing and disappearing constantly, does anyone of you know what this is mean?
