A-MEDIA AUTO MTCE_CHS_V3.76_1 Bluetooth Problem - MTCD Android Head Units Q&A

HI all, I have a problem with Bluetooth on the following A-MEDIA AUTO head unit:
Model
PX6(1280x720)
Android version 10
Build number rk3399-userdebug 10 QQ2A.200305.004.A1 eng.hct.20210902163038 test-keys
Kernel version
4.19_111+
#158 Wed Aug 11 15:57:41 CST 2021
MCU version
MTCE_CHS_V3.76_1
May 13 2021 15:42:50
CPU
Dual-core Cortex-A72 @ 1.8G
Quad-core Cortex-A53 @ 1.5G
Memory
3841MB
I know Bluetooth problems appear to be legion on these Chinese head units, but maybe someone can help me sort this out. Now there is no problem pairing any device with a PIN: mobile phones and OBD2 dongles pair up just fine. But I have a lot of Bluetooth devices and applications that communicate directly - no pairing required - such as battery monitors, BMSs, mobile phone repeater units. These devices/applications used to work on my old Android 9 head unit (different chipset entirely), but now on this new Rockchip 3399 Android 10 unit, none of them can communicate at all.
I'm not sure if it's an Android 10 problem, or (more likely I suspect) a broken Bluetooth implementation in the MCU. Another problem is that audio pass-through from the mobile phone doesn't work at all, even though all other phone operations work as they should.
The Bluetooth driver setting in the unit is set to WQ_RF210. I've tried all of the other settings for fun, but of course there was no improvement.
Is anyone able to shed any light on this?

EONON G2110F or G2110ZV Firmware Update Caused RADIO and WIFI to be non operational

I need to restore the operation of my Radio and WIFI for my EONON 2110F after a Firmware Update. The Radio APP displays and responds to user input, but no sound, the WIFI fails authentication. Below are all the specifics that I thought would be helpful to anyone who could help.
I was told to update my firmware by the Manufacturer and now the Radio and the WIFI do not function. The Bluetooth and DVD function, but I can’t enable the Navigation without the WIFI, so the GPS is uncertain.
Any help would be appreciated

I purchased an EONON G2110F or G2110ZV Head Unit from EONON EBAY. There were a few issues I had with the Head Unit, some were my lack of understanding and 3 were the unit.
1-The Steering Wheel Control would not work reliably with my 2004 Honda Odyssey.
2-The Weather App was not finding the region I entered so it never updated.
3-I could not connect my music on my Apple iPod Touch to the Head Unit, the iPod is Model A1288 with IOS 4.2.1, although my iPhone 4 with IOS 7.2.1 music could be played.
These were minor issues compared what I am now dealing with the Head Unit.
Asking Support at EONON was very aggravating. They would not answer my questions correctly. Such as if I asked them about my problem connecting my iPod Music they would send me a video using an Android. If I asked them about the Weather App not working, they told me to perform an update without providing the files or instructions. If I asked them about wiring up the Remote Steering Wheel Control, they would send me a video showing someone with a phenolic perf board with buttons on it performing the remote control operations, with no wiring detail.
Any help would be appreciated
Just installed same unit myself today, will share info as I learn more...
Okay, everything spec. wise and operations-wise is on the Eonon site...
http://www.eonon.com/Android-Car-GPS/2-Din-GPS-Navigation/G2110F.html
Now, I myself am running a custom Lollipop ROM on it, that's also got root access. Only thing I don't like about it? The notification bar on KitKat has an icon which switches the screen off, so making the car interior dark during night drives. I'm hoping to get a message to the custom ROM's developer, Malaysk, and ask him about including that feature in any new ROM he makes for the RK3188 800x480 head units, like ours.
To find out more about our unit, visit the Android Auto section here at XDA. Malaysk's ROM, and others, are available there.
g2110f in a bootlock
I had that same problem, and corrected it by holding the "HOME and POWER BUTTONS" together holding until you hear three beeps, release and short press the power button.
It booted to the system set up or recovery, Use the power button short press to scroll down to recovery and clear cache. Long press power button to start the recovery process.
When prompted finished, restart the unit. Mine booted up normally!!!!!!
You'll have to reset your clock and other operations.
Goodluck!

I'm working with DRL problem all 2 months of this android multimedia.
I'm turned on DRL in PP2000 and it works with original peugeot radio. Multimedia turns it off.
I guess this is Canbus problem and it seems that today it is still not solved.

Hi,
is there a verified CANBUS that works well with 407?
I have following one:
PA-SS-07 20191229 SW:V1.00.012BYPS P/N:1814600028
used with PX5 9.0 4+64
rk3368-userdebug 9 PI 20200103.122402 test-keys Kernel 4.4.167 #193 Fri Dec 13 17:27:06 CST 2019 MCU version MTCE_MX_V3.41_1 Nov 15 2019 12:50:10 Octa-core Cortex-A53 @ 1.5G memory 3940 MB
I don't have parking sensors, so no issue there, the problems I observed are:
- no DRL (lights stopped switching on automatically, options in the Android app don't have any result)
- temperature not shown, I see no options to activate that in radio
- HU doesn't turn on on ignition ON every time, sometimes it's needed to start the engine first
- climate temperatures seem to be wrong - in the original controls it defaulted to 21 deg when turning on ignition (Webasto parking heater resets it), on the Android device it shows 23 deg, I don't know if 23 is equivalent to 21.

Erisin PX5,Android 9.0 Bluetooth issues

Hi,
I was wondering if I could get some help with my issue. I bought an Erisin ES8049U head unit that I am trying to connect to my cars after market engine management system via Bluetooth. The head unit discovers the engine management system but it's quite troublesome to connect to it. Sometimes it connects, sometimes it doesnt. The Bluetooth connection to the cars engine management unit works fine from my Samsung mobile, so the problem is in the Erisin head unit.
Also when I finally get it to connect, no data comes through to the engine management system, it's like its not even connected and sometimes it flashes connected/disconnected.
Here are the info on the system:
PX5
Android 9
Build: rk3368-userdebug 9PQ2A. 190305.002 20191113.183229 test-keys
Kernel: 4.4.167
MCU: MTCE_LM_V3.43_1 / DEC 17.2019
CPU: Octa-core Cortex-A53 @ 1.5G
BT chip that has been selected in the system by default is: SD-8350
I've read some of the BT connectivity issues and they mostly have had different BT chips installed, at least originally. Any idea which chip I could test from the list, or is there a MCU that would fix connectivity issues? Or any other things I could do?

OK, I got it to show the data from the engine managament unit when I disabled Wireless and after that it started connecting. But if I restart the car, it doesnt want to connect to the application. With my phone it works flawlessly. I wonder if it's an application error or something to do with the head unit.

Help: Audi a3 with android head unit

Hello, all good people, professionals, beginners. I am Slovak for the introduction and therefore your language is not my natural so I apologize in advance. What i can't write, translate in google.
I have audi a3 12.2009 sportback gen2. My original radio 8P0035186P.
Air condition 8P0820043BH
Central electrics 8P0907279N
Gateway 1K0907951
Parking assitance 8P0919475B
Steering assistance 1K0909144C
Dashboard 8P0920931T
I buy android head unit px5 1024x600 rk3368 A10 octa core cortex-a53 2gb ram 32gb rom. (mtce_chs_v3.67_1 Nov 7 2020) (core 4.19.111+ Nov 23 2020) Canbus decoder CHS 20201201 A3/A4/TT HW:v3 SW:v1.
What works: steering wheel control, day / night mode change via sensor, battery/alt voltage - that is all. Used CANBUS protocol audi A3 simple 1/2 gen in factory settings.
I have the following problems and questions: The car does not communicate with the radio at all. Radio does not display vehicle management, applications or something for any communication between the vehicle and the unit. When I change the canbus protocol to golf7 or high class audi in factory settings, will be displayed after restart - vehicleapp and controlsettingsapp. When I run the application in canbus golf, turns on but everything is unavailable. As a layman i tried to pull the app from canbus golf7 to my audi a3 simple canbus and install. The application will install, but stop immediately. What I'm doing wrong or where I should look for a mistake according to you? Why I don't have these applications there at canbus a3 simple?
I called Audi support and I asked them supports my vehicle these things: Parking radar/assistant, open doors, air conditioning, tpms and more.. They said yes but only if you have rns-e radio. Rns-e dont have bluetooth and other good staff so i buy this and I am unhappy. I use obdeleven when I turn on a function, for example parking ilustration the function will disappear from my dashboard and for me logically sends the sensor control to the radio. But no and why? it's radio too waste or audi just can't do it? I will answer every question by attaching any file ask anything.

IDOING PX6 Pro zlink freezing problem

Hello, I have an IDOING ROCKCHIP PX6 radio ( https://es.aliexpress.com/item/1005001556699902.html?spm=a2g0o.order_list . order_ list_main.74.21ef194dVBJqix& gatewayAdapt=glo2esp )
I am having problems with the ZLINK version 5.3 app that when I connect to my android phone wirelessly it freezes the image every 50 seconds and then refreshes again. Sometimes it doesn't update right away and I have to go back to the start menu and open the android auto app again.
Complaining to idoing via aliexpress I no longer have support and a solution on their side since I have to send the radio to China and the cost is higher than the radio, could you help me solve my problem
I am afraid of making a bad update and the radio will go black without recovering it
