Eonon Android 5.1.1 bluetooth issues & canbus issues

hi guys
new to the forum, hopefully someone will be able to help me
my unit has stock MTCC-KLD6-V2.97 Aug 02 2016 with a RK3188 and 1024x600 screen
Firstly the Bluetooth is not working, quite a lot of apps hang at the part where it try's to turn the BT on, especially one app i really need to work.
I honestly don't know what model of BT chip is installed in the head unit, apparently its BT 4.0 as listed on there website
I have been into the factory menu and changed the BT from WQ_BC6 to WQ_BC6B (as suggested somewhere in this forum) but it has made no change and the BT is still hanging at powering on.
Eonon have told me that the Bluetooth only work with devices that don't require a pin and the radar detector device i need to connect does not require a pin but still it does not work.
Not quite sure if eonon has set the setting wrong and i need to change it or i need to goto a custom rom or I need to pull the unit apart to find out.
Found someone else having trouble getting there ALPconnect app to work aswell on these units, in know ALPconnect wont work on older unit like the 4.4.4 as they only had BT 2.0 and the ALP BT only supports 4.0, but this android unit has 4.0 so it should not be a problem but it is.

The app I use, ALPConnect, does the exact same thing. Fortunately, the hardware on mine includes a hardwired speaker and GPS setup that work standalone. The benefit of the app was to get a nice big visual notification of a trap, as it would come into focus, duck the audio and play an alarm. It would also report the frequency of the radar and the type of laser hitting me. While I can get by without all that, I can't have the music blaring like I usually do, as the little speaker is only so loud and the Joying head unit doesn't have Mute Input wire to duck the audio.
While this is going slightly off topic, you may want to look into the AL Priority, it can interface with your V1 too and you will also gain laser protection. This thing has saved my a** countless times and paid for itself already many times over.

Secondly the control menu in the android head unit for accessing the cars buttons via cambus does not work, all steering wheels button seem to communicate back and work, but i cannot set my clock on my mazda 3.
Also have noticed that the radio wont mute when notification occur or when using other apps like google maps, no way to set the different volumes in this stock rom. Have played around with the factory menu volumes but it makes no diffidence.
Is it viable and worth changing to a different ROM, like Malaysk? or should i message eonon?
any help would be much appreciated
thanks

I'm having exactly the same issue with a Pumpkin MTCC-KLD6-V2.91. (RK3188/1024x600)
The device I want to pair with appears in Bluetooth settings (with a phone icon?) but connecting to it does nothing. It's just a Bluetooth SPP device, like so many other devices.
Malaysk's ROM (from 7/25) doesn't change anything here.
Any suggestions would be most welcome.

Waiting on a reply from Eonon, but initial news is not good.
Some serious BT issues in this model the MTCC
Anyone know if any Malaysk's Rom's avalable for the MTCC-KLD6-V2.91 that have no BT issues

I'm having the same issue, though my unit (MTCC KLD6) does not show any devices at all to pair with, and the car unit does not appear on my phone.
I'm wondering - if I take a usb BT dongle and attach it to the usb cable, would that work?

I think it might be another issue with your BT, it should connect to your phone at very least.
Have you had a look in your factory menu to see if the MCU has the Bluetooth option set?
Password for me was 126
Unfortunately the unit does not support external USB Bluetooth and probably never will, unless the manufacturer MTC/Klyde adds the required drivers to the unit or a Awesome developer by some stroke of luck here adds it to the unit. I doubt to see the feature in this unit

Thanks for the reply. Yes, i checked to make sure Bluetooth was enabled in the system settings. I've tried a few of them (change setting, reboot, attempt pairing), i guess the next step is to try them all one by one to rule that out. I've sent an email to the seller to see if they have any ideas.

The vendor told me to connect the Key-1 & Key-2 wires from the canbus to the car, not sure why they'd think that would solve BT issues?

Did this fix the issue? I'm unable to see any Bluetooth devices and other Bluetooth devices don't see it.

Sorry to dig up an old thread
I have the Eonon GA2180a (android 10) - and having similar issues to here
I want to pair a bluetooth remote (read, steering wheel controls) to the head unit, but the bluetooth search just shows blank! I can connect to it using my phone but it appears some things are hidden to connect to with these android units? Looks like the bluetooth 'app' is the only way to connect too, theres nothing in the android settings to access a bluetooth menu or anything.
Did anyone get anywhere with this ?
cheers

Joying PX5 Android 8 4Gb Ram 32Gb - google voice services not working

I just installed a joying JY-UO138P4 (https://www.joyingauto.com/joying-l...ouble-din-car-audio-system-with-4gb-32gb.html ) in a 2006 Pontiac Grand Prix.
Most things work - I am still working out the steering wheel control wiring with Metra Axxess and Joying - I think this is an issue with Metra identifying the car correctly, I had a similar problem with an older metra unit on a Sony receiver.
One thing that doesn't work is accessing google voice services when I click on the microphone, I get a message 'Cannot reach google at the moment'. I am connected via wifi and can open the Chrome browser and get to google. All other internet access I tested works fine as well.
Does anyone have any suggestions on this?
p.s. I'll probably have other questions on improving the UI - would like a better blue tooth phone client, and something better with the radio.

Search the forum. This has been mentioned several times. Google voice currently doesn't work. Joying is working on it.
A lot of us have questions and remarks on the UI, on a lot of aspects, and on the functionality. Most/some of us are already pushing Joying 2 years for improvements. Some improvements and bug fixes came, others not.
Please help pushing by directly mailing to Joying ([email protected]) about your comments and questions, but don't think you're the first.
You don't mention your issues with the Radio, but if it is about layout: see here.
Those radio mods are made for the Sofia units, but work just as well on your type of PX5. I'm using one of them (and the PX5 models ending on P2 or P4 can use the exact same software)

Thanks for responding, I did find a rom on their site (have the link on my home machine) , not sure it is for these devices, just says for 2gb/4gb 16gb/32gb Octacore, but from the looks of it, it is an AOSP build.
After trying an older 'personal assistant' app AVX Extreme, I found out the google speech to text module is missing. - this thread (https://groups.google.com/forum/#!topic/android-building/Gu8c8JLMo6w) shows that it is not part of AOSP, so if we can figure out how to get the speech to text module installed, I think it will work.
As for the Radio, it is a layout thing, it is not a bad layout, but I feel it could be better somehow. I'd like to find a launcher that supports the OBD-II input for speed/etc, a nice clock, radio/volume control, and navigation
I see you also have a thread on the 8.0 build so I will follow up on there.

You have a FYT hardware model (models ending on P2 or P4). The firmware you see there is for the QD models which are completely different and completely incompatible with regard to the underlying hardware, drivers, etc.

Hello
i have received the P2 unit and Google voice not working
Some news from Joying about this feature?

Dit you managed to get the steering wheel control wiring with Metra Axxess to work on your Joying? I also need a canbus decoder for the joying i'm planning to buy. Can you recommend the Metra Axxess, and is it difficult to connect the wiring?

Yes- I got it to work, though don't ask how I had multiple back and forths with Metra on it- for some reason the Axxess could not properly detect my car, metro told me the instructions printed and on the pdf could be wrong and I should try ""VOL UP, SEEK UP, BAND, MUTE, VOL UP"" - but that didn't work. At one point I got frustrated working on the car, and reset the Axxess for the 20th+ time, and didn't notice the steering wheel was turned, so i hit the buttons 'upside down' - I am not sure the combination, but once that happened everything is working good.
In my car, two of the buttons overlap - so I have 6 buttons I can assign instead of 8, but the important one (Seek/Volume/Mute) are mapped so I am happy.
I am not using CANBUS on my car, so I can't speak to that, though I am trying to find out if there is any information anywhere on connecting to the build in HUD in my car.

bmw f30 android 7.1.x head units

Hi,
I am trying to buy an android head unit from aliexpress for my bmw f30 2013. Very few sellers answer questions and not to the point.
e.g.
1) does it supports after market front camera through RCA input and how easy is to select it? (e.g. does it appear automatically right after reverse gear)
2) does it support can bus messages or do I need a can bus converter. I have already tried 2 multimedia interfaces (IW06B-N23 and QHI-BM12) but they dont trigger the camera. So how to be sure that the same will not happen with the android head unit
3) which MCU is used in order to see if I will be able to find updated firmware on xda forum
4) will I hear oem radio during google maps navigation (hearing also google maps directions)
5) will it connect automatically to my iphone hotspot for internet
6) will it work for iphone 11.2 mirroring
7) will it show perfectly the oem screen
8) would I be able to use steering wheel controls for bluetooth and which bluetooth will I be able to use? the OEM one or the Android one?
9) would I be able to use idrive in google maps
All of the above I believe are very basic information that you cannot get from sellers. I dont understand how they sell or I am missing something here.
Is there anyone here with similar problems so we can help each other?
Regards,
Mike

With a name like Mike, you're maybe English or American? I really suggest buying locally. You'll pay £/$30 more but you'll get a warranty and protection from your local trading laws. Buying from China is a game of Russian roulette. I bought an Erisin from China before and it was absolutely fine. Lucky that, because one I bought from England was not fine, and I had to return it. Had it been the other way round, I'd have been in a world of trouble and £100+ down the ****ter.

On mine, there's a setting for it to switch back to the front camera after the rear camera has been operating.

It will come with a canbus decoder unit. Any unit worth it's salt will work correctly with your PDC system. Mine does.

MCU is not important. It's the brand that puts out firmware updates. Xtrons, Joying and Eonon have fairly solid reputations for their updates. Xtrons have put out 5 so far for my unit. Erisin have a fairly flakey reputation. The rest are going to be a complete gamble and more likely you'll lose.

OEM radio? You're removing the OEM radio and replacing it with this. If you mean will you hear the radio and maps, yes, the maps software dips the volume in a very polite way

Firstly, sack off the iPhone, it's crap and there's so many things you can do with Android that work with this unit (mine triggers the hotspot on and off when i get in and out of the car). In answer to your question, yes, you can connect it to your hotspot.

You're mixing two entirely different software packages up here.
To conclude, if your car has iDrive. I wouldn't go anywhere near one of these systems, it'll be a ****ing minefield making it work. If yours is non iDrive, like mine, then it'll fit perfectly with no issues

Thank you for the supplied information. I am from Greece/EU and locally there are no such products.
Chinese solutions for BMW F30 are mainly changing only the screen (which is detachable) and the new one includes all the features inside the screen, so the main OEM function remain in-place.
I would take a look at xtrons as I have seen various posts here and they have a decent website hoping to receive updates but I dont know yet if they have an EU warehouse because import taxes is my country are very high. My concern stays for idrive and canbus integration mainly because I have already tested 2 other types of interface and non of them worked.
Lets see if xtrons will reply on aliexpress with more to the point questions!

Your car has iDrive? Be very careful. Those systems are so much more complicated. The reason the non-iDrive works is because it's actually still a simple system. It's just a whole bunch of relays triggered by other relays and a few more relays and then somewhere there's a computer that does it all. iDrive has it's own dedicated computer which does so much more and offers so much more functionality, and that's where you might find problems. Getting those two systems integrated could be an absolute minefield.

Not sure if you are still around or found more info but the above posts are incorrect. The unit you are buying is more than likely the 10.25 screen upgrade with Android built in. It will work in tandem with idrive....everything works and it is easy install and upgrade.
https://www.aliexpress.com/item/10-...00a8-4760-8b00-b2efeaa2fb7e&priceBeautifyAB=0

So a stupid question, it seems there are several Chinese companies that sell these 10.25" Android panels for the F30 BMW. Though the interface looks exactly the same despite who made the tablet, is there really a difference in the ROM image between makes? The one I have is from COG Android (atleast that is what the Bluetooth ID says). I have had in other cars Joying and ITOPWay, are they really something different ( I almost suspect they are the same company)?

Joying Head Unit (4GB, PX5 Octa Core) - Bluetooth Tethering

Hi All,
Recently purchased and installed a Joying head unit (4GB, PX5 Octa Core) (link to product)
As this head unit runs android I am trying to tether the mobile data on my android mobile over to the head unit via the bluetooth tethering function. Problem is I dont think its working. Does anyone have any experience with this or know how to get it working?
Steps:
On the mobile, make sure its connected to mobile data
On mobile, turn on bluetooth tethering
Pair mobile and head unit via bluetooth
Still no internet access

Can you access data via hot spot? Make you mobile device a wifi hotspot and connect the headunit to your hotspot.

Yeah I tried this and it works fine. I just though it be better to use bluetooth tethering seeing as the phone is already hooked up to the head unit via bluetooth. Using the WiFi hot spot option just adds another process to the mix.
Because Joying remove a lot of the standard android setting I was thinking there might be a way to access the default android settings again to be able to play around with bluetooth properly. While writing this thread up however I did email Joying about the ability to bluetooth tether and their response was:
"Our head unit can not support Bluetooth tethering"

Hi, I am trying to achieve the same solution however I do not think it's possible. My understanding is that the bluetooth connectivity allowed by the hardware in the head units doesn't cater for the 'full stack' of bluetooth functions, so we're stuck with telephony and audio only with no data transfer.
I would *really* love to be corrected though! It would be great if it could be solved by software alone.
Failing that, could a bluetooth USB dongle work to provide full BT support?

I consider this a bug. It did work on the Sofia 3GR units on Android 6.0.1.
It (currently) does not work on the Android 8 PX5 FYT units (like the OP has as well). Can't say anything about the QD units.

Well that gives me some hope at least.
I did note at least 3 'Bluetooth' apps running on my device (that I've been playing with since my previous post).
Perhaps a custom mod may be the answer...

Sorry proto, I've had about five units and all the same. You're right and it sucks. I don't think it's a big as I've come across it many times and only in a few eBay postings did the seller actually specify it has a general bluetooth connection. Otherwise toy even have to buy their obd to get that to work

Ok thanks for the replies. Hopefully it will be fixed with a firmware update in the future or something.

Is there are any news about this Bluetooth tethering?
I am really interested because my WiFi is really really slow...
I saw that some Bluetooth function are missing, like the possibility to remove paired device or select Bluetooth tethering.

It’s highly unlikely Joying will fix the Bluetooth, they would need to produce a seperate rom with normal BT configured and u would not have access to the Joying BT app.
Currently Joying route all Bluetooth communication via a service called btlink, from there it goes to the joying bluetooth app.
Joying have fundamentally changed the way the Bluetooth is configured so it functions with only their software.
All these headunit manufactures do this to the BT so it functions with their software and they never offer a fix

From which library/framework/binary/whatever is this btlink service started/called?

Remember that it only worked with a HACK. Joying intentionally disables this functionality.

Bluetooth information
Init.sy.rc
Service blink /vendor/bin/blink
Init.connectivity.rc
Chmod 0666 /dev/tty (This should be tty00)
Now I have modified mine but I think the system/vendor/ect/Bluetooth/bt_vendor.conf is set to
- UartPort = /dev/tty00
Blink is interacting with /dev/tty
Android system is interacting with /dev/tty00 ?
Hopefully all the information is correct as I have modified my unit lots to try give back the Bluetooth to the system and I didn’t keep many notes.
But in short the the system is trying to access the Bluetooth on the wrong Uart port, where as the blink is attaching to the tty device, allowing the joying software to work.
This prevent the android system & apps interacting with the Bluetooth.
Also this is the test app I have been using to try to get it to allow permissions to turn BT on, but it get denied every time
Bluetooth Discovery : Bluetooth LE Scanner
https://play.google.com/store/apps/details?id=com.manjul.bluetoothsdp

i have the 10.1 american version.
if i remember correctly, bluetooth has an issue when your using it as a "media" access point
i think the bluetooth is set for A2DP... probably physically somehow.

Did you try to create a symlink like

And is it indeed tty00 or tty0?
Did you give the scanner root access?

Bumping this for a slightly odder issue. I'm trying to connect my Joying stereo to a Hondata KPro ECU, it sees the ECU but refuses to link to it in settings, rendering apps like Hondata or RealDash useless, so in turn I'm using a crappy $20 tablet until someone can show how to fix this BT issue.
Joying was no help other than to tell me to buy their OBDII adapter, which I did, but LONG story this is a 2008 Honda engine in a 91 MR2 that has no OBDII port. I've bought an OBDII port off eBay and tried using pinouts from the ECU to hack together an OBDII port but no luck.
Having it via Bluetooth would be easier, it sees the KPro, so there must be a way.

same problem
dont buy this joying head unit
its rabish

Custom or modified rom to enable full bluetooth use?

Hey guys so I have an Alfa 159 and bought one of these head units:
Edit i cannot post a link however its the generic A-media Auto alfa 159 head unit which can be found on google
now I was speaking with a friend of mine who explained that the roms are "cut back" and removes some features and full blurtooth control/ support is one of them
I am reasonably ok with computers but never ventrued into any sort of custom android stuff and the extend of my knowledge is " i know you can get custom roms" i hdon't know how to do them or use them etc.
I have some bluetooth modules i can control from my phone in the car (lighting and actuators) but would love to be able to do it from the head unit
Would it be possible to get a custom rom for this head unit and if so any guides at all?
I would like to point i did have a search but honestly i am not totally sure what I am searching for and searching sepcifically for this head unit didnt help.
Thank yoiu very much

It's not so much that the ROM removed bluetooth features as much as it is how the bluetooth module is integrated to the HU. There's 2 system boards that make up the HU. The SoM has the Android system and is basically a tablet motherboard with only a display, audio and USB connection. The MCU provides a USB hub, audio preamp and power amp, connectivity to the car and the bluetooth module. The bluetooth module is treated as a headset controlled through a serial connection with AT commands and this is where the problem lies with using bluetooth with any apps other than the built in ones. It works for ODB dongles so it is possible but if the functionality you're looking for is not already implemented I doubt someone else would be able to add it to the MCU ROM. All I can say is try and see if it works.
Maybe you can try to connect a USB bluetooth dongle the issue here would be Android drivers.

Thank you, sorry for late reply.
A friend of mine figured out with his that it was "nuked" in the software allegadly. the bluetooth module is a generic module but unfortunatly I am not massivly clued up on reflashing roms or even where to start especially on a head unit which is a shame.
My friend unfortunatly has since moved country so I can no longer ask him to take a look

I don't suppose anyone else might have an idea to this?

this comes up often apparently nobody give f*ckall to address this issue.

^ Thats a real shame

i know, my radio is great, does everything great. I just want to connect bt to my ham radio and use this as the head unit. and I was thinking about using those bluetooth valve stems so i can see the air pressures in my tires, looks like those wont work either.

Have you considered that these units work for the intended use and if it doesn't work for some obscure use case the desire to solve a problem for single users is limited. To expect others work on an obscure problem for you seems a bit entitled.
Have you considered taking the lead on this issue.

Bumping to see if ANYONE has came up with a solution, maybe an external dongle?
