how to connect internet via bluetooth? Thank you
[Android Head-Units] marchnz:
You don't.
[Android Head-Units] MarkOrkenyi:
I have the 11/04/2020	os_update_KC1E0110-P01-1.1.4.3.1_20200411_110825.zip equalizer empty no flat rock etc for an Eunavi HU. Therre is EQ, but text is black.

Also, i tried to install the mcu-20200103-1001KC6-1027.upd, but the MCU version remains the -33. Did anyone success with this?
[Android Head-Units] Dape84:
I do not?
[Android Head-Units] Michalec:
Maybe he meant that you cannot do that?

I've tried but didn't worked. Bluetooth module is somehow broken in those HUs, because I cannot connect more than one device and seller is dump because he says that "multiple devices is not possible with Bluetooth by standard". I've sent him screenshot showing 2 devices connected on my old headunit and he said "impossible how did you do that??" [emoji23]
[Android Head-Units] OperatorB:
Just a note: Technically only BT5.0 can connect 3 devices together. Below 5.0 only two device can connect to each other at a given time. (You should be able to PAIR as many as u want.) :fingers-crossed:
[Android Head-Units] Michalec:
Yea, I know. And this happens on that HU:
[Android Head-Units] Dape84:
I only want to connect 1 device, but take the internet via bluethoot instead of wifi
[Android Head-Units] cmo_sec:
For me bluetooth tethering is working, but I have to disable wifi at first:

Disable wifi on your HU

Enable bluetooth on your smartphone

Enable bluetooth tethering on your smartphone

Wait some seconds... Connected + internet is working.
[Android Head-Units] Dape84:
many thanks!! was that, you have to disable wifi:risa:

it's always same mcu file ! stupid Chinese
[Android Head-Units] camnop:
My head unit works very nice, my wifi, my cell phone and OBDII connect at same time. my ob2 is a little bit large so I bought and tested two others obdii and my HU didn't connect.

How can I know which Bluetooth version is mine?

Details of my Head Unit:

Bosion - no DSP - 9 inches

[*]Android 9 API Level 28

[*]RK3399 - ROM 64GB - LPDDR4 4GB - 1024X600

[*]Kernel Version: Linux 4.4.167+ - Fri SEP 27 09:08:20 CST 2019

[*]OS Version: KC1E0101-PA1-1.1.4.3.1 - BLINK161 - 20190926 - 701F

[*]MCU Version: STM32-20190918-11-KC6-37

[*]Radio Chip Module: MPU Control.7786

[*]BT Module: BLINK-161

[*]Display Type: HD(1024*600)

[*]No sd card
[Android Head-Units] OperatorB:
To simply verify you need two BT5.0 enabled audio devices (headphone/speaker) and connect to them one after the other, without disconnecting. If the HU streams audio to both simultaneously than it is 5.0 or above. (It is called dual mode.)

Actually your BLINK161 module is BT4.x I can grant it.
[Android Head-Units] pinotuning:
so it's fake !! the seller declares BT5.0 on head unit with dsp ! on my I read BLINK161 ! means that bleutooth module is 4.0! always fake Chinese

Boison headunit issues

I bought a Boison branded headunit from AliExpress recently and the main issue I have is that it does a full shutdown everytime the ignition is off.

It takes about 25/30 seconds to boot up every time which is very frustrating. Is there a way to get it to quick boot instead of a full boot every time?

Shouldn't it go in to sleep mode? When I delay the shutdown from the menu the music keeps playing when I take the keys out which isn't right either.

Any help would be really appreciated!
[Android Head-Units] krefo:
I also have a Bosion from Ali and I saw somewhere in settings option with chooses for shutdown setting. Something like "fake shutdown" and "full shutdown".I do not remember the exact wording
[Android Head-Units] Hol47:
Ill have a try now and see if this fixes it. Did this fix yours?

Does it drain the battery with this setting?
[Android Head-Units] Hol47:
Update - There are 2 settings 'False Shutdown' and 'Really Shutdown'. I cant see any difference to the functionality when changing between these two however.

Surely it shouldnt take 30 seconds every time you swtich it on?
[Android Head-Units] Michalec:
I have the same problem. Seems like software issue, because on my old HU sleep mode worked just fine. On Boison/Eunavi HU it's broken and indeed annoying...
[Android Head-Units] Hol47:
Its very annoying. Think i may need to send this back if i cant resolve it. Does anyone know of a fix?
[Android Head-Units] OperatorB:
Guys are you sure that ignition line is wired to the corresponding line? If not it could easily explain why is your issue.

If you can get a bench PSU you can experiment with the HU before further action. You need only 12V, GND, and Ignition which is usually 12V when ON and 0V(GND) when OFF. (Hint: mute the HU as soon as it boots into android, safety reason)

As far as I know this functionality is handled by the STM32 IC and its firmware, not the android OS.

:fingers-crossed:
[Android Head-Units] Hol47:
Im pretty sure that isnt the issue. The unit swtiches on and off with the ignition and maintains all the memory. The only problem is it does a full boot every time rather than coming on from a sleep mode.
[Android Head-Units] OperatorB:
Ok I see, I hope you get the right firmware soon!
[Android Head-Units] Michalec:
I'm pretty sure that [MENTION=10715529]Hol47[/MENTION] connected his HU using canbus, that handles everything, just like I did. In my previous HU connection was the same and everything worked.
[Android Head-Units] fordcamper:
boisson radio

I also have Boisson radio and I had the same problems, it turned out to be the connection via canbus, I took it out and connected it again via the standard method, the key wire also directly connected to key 1 of the car, everything works now before I found out. a few days ago I almost also used my previous radio again
[Android Head-Units] Hol47:
This sounds promising. Do you have more details on what you did exactly? So you didn't use the canbus at all?

I'm not connecting anything to the key wires currently?
[Android Head-Units] krefo:
I haven't tried this yet
[Android Head-Units] fordcamper:
Hi to me the problem was via the cable harness, it turned out that he got power in two ways, namely via the canbus and I immediately separated that when it turned out that he worked better without the canbus as it had to, only the steering wheel control did not work but I solved that. by connecting the wire of the canbus directly with the plug of the car it is the wire from key 2 to key 1 it worked then so I have removed the canbus now it does as it should, with canbus it keeps on staying permament , I must mention that the car is a Ford transit
[Android Head-Units] Hol47:
This sounds like a different issue to mine. My issue is that the headunit does a full shutdown when the ignition is off rather than a hibernation/sleep mode which means everytime it's switched back on it has to boot for 30 seconds rather than switching on instantly.
[Android Head-Units] MarkOrkenyi:
There is an option somewhere called "ACC off delay" or something like this. I set this to 30sec and it resolved this issue. If i crank the engine, the HU resets, but in a second it is working. After turning off the car, it indeed takes 30secs for the HU to power off, but that's okay in my opinion.

Another issue i found probably is that the sound quality is "less-than-ideal". I'm waiting for the ROM to try it with Viper4Android....

I would recommend everyone who bought this unit to ask for a refund ASAP and/or wait for Malaysk ROM. All my hope is in that ROM :D
[Android Head-Units] Hol47:
If I set the ACC delay then music still plays when I turn off the ignition and take the keys out. It's definitely wired correctly. Seems like a fundamental issue with these head units.

---------- Post added at 08:36 AM ---------- Previous post was at 07:57 AM ----------

Will this ROM fix the issue of the device having to do a cold boot every time? Will it be able to sleep properly?
[Android Head-Units] MarkOrkenyi:
Depends, for me, with spotify it does plays for 30seconds, then turns off. The radio however turns off immediately, and i can see that the HU turns off completely after 30s. Yes, 100% software issue, but until there is a custom ROM available, you can't do much .:)
[Android Head-Units] Hol47:
Think I'll send it back in favour of getting an xtrons. Noticed today that the split screen on mine only refreshes the half that's currently selected.

E.g. gps wont update position while music is active in the other half.

Seems way too buggy at the moment.
[Android Head-Units] pinotuning:
I don't have these problems! in my opinion the problem is canbus
[Android Head-Units] Hol47:
So you think if I remove the canbus completely it will sleep instead of shutting down? are you sure you have the same unit as me?
[Android Head-Units] DreadfulDrummer:
Mine is set to 2 hour shutdown delay and, if I don't pause Google Play Music before removing the key, it continues to play silently for 2 hours. It's quiet annoying... get it? It is quite annoying though. Along with the gimped Bluetooth and other, more minor issues like the fake however-many-band EQ they've put in there... Is it my fault for buying the cheapest PX6 head unit I could find?

I've no canbus, btw
[Android Head-Units] Hol47:
Yeah my Bluetooth stopped working yesterday too. Had to do a full reboot to get it back. I'm going to see if AliExpress will refund me and I'll get a proper px6.
[Android Head-Units] pinotuning:
I don't understand what problem you have !! in my unit I set delay to 10 minutes and when I start the car after a stop my unit starts immediately without booting! in the morning the first time I turn on my car ... my unit starts with the boot in about 25 seconds! this is all normal !

on aliexpress I saw that on the vag group there are different connections of canbus ... maybe the problem is this !? these units all have the same firmware but the canbus is managed in mcu software to adapt units in other cars
[Android Head-Units] Hol47:
That isn't normal for any other headunit than these STM32 units. Happy to be corrected but I believe other units should go in to a sleep mode and not have to cold boot from scratch taking ~30s even if left overnight
[Android Head-Units] pinotuning:
my unit is eunavi with mcu stm32
[Android Head-Units] Hol47:
So yours will do it too. 30 seconds to boot in the morning isn't what others do.
[Android Head-Units] Michalec:
Mine is Eunavi too. My old HU was connected the same way, the same canbus option in factory settings - sleep mode was working as it should.

On Eunavi it's still playing music and button panel is turned on. I'm not gonna change connection - that's why I bought that HU with canbus support... It's software failure for sure. Maybe VW/Skoda canbus is broken on MCU side, and that's why for some people there is no problems?
[Android Head-Units] pinotuning:
I do not understand what you mean ! even my old "mtc" unit was like this! if the unit starts in 25 seconds in the morning it's fine for me! I set a delay of 10 minutes and it's perfect for me! why should i leave my unit on at night ?? explain to me the reason!
[Android Head-Units] rudix78:
Try to choose different canbus in HU options.Maybe different config option will work. For me I have 37 years old truck without canbus support and shutdown delay works as it should.
[Android Head-Units] pinotuning:
another confirmation that the problem is canbus !! we all have the same firmware so the problem is in the mcu software that manages canbus! my unit is universal without canbus ... shutdown delay works fine
[Android Head-Units] pinotuning:
i found this on aliexspess for headunit group vag ! maybe it can help
[Android Head-Units] Michalec:
I have connected my canbus the same way as in picture. So it's definitely software problem with handling canbus.
[Android Head-Units] pinotuning:
in your car canbus is necessary? if it is not necessary to remove the canbus module, put yellow wire + 12v battery, red wire with ignition key and you solve everything
[Android Head-Units] Michalec:
I'm using canbus functionality a lot ie. ACC voltage, climatronic status, oil status & other useful stuff
[Android Head-Units] pinotuning:
sure but i mean if canbus is needed for headunit...
[Android Head-Units] Michalec:
I'm not sure what you mean. By using canbus I can see a lot of useful information on headunit - Car Info application for example. Without canbus connection those informations are not available.
[Android Head-Units] donbrisko:
Hey everyone,

did someone experience random crashes aswell? I wasn't able to see any relations to temperature or specific apps yet. Even without workload it sometimes just restarts or crashes with completely distorted screen.

Having the 110 unit with recent firmware + software from this thread (same behaviours before update)
[Android Head-Units] Majster25:
Hi,I need an update file software version? " KC1E0110-P01-1.1.4.3.1 - BLINK161 - 20200104 - N3" ?

I would like to update my radio.

I have a problem I installed the latest version

KC1E0104-PA1-1.1.4.3.1_20190929_181347

but the radio freezes on the welcome screen

MCU VERSION: STM32-20200103-11-KC6-33

?
[Android Head-Units] rudix78:
Crushes no, but failure to boot from time to time. In my case HU does not start properly. Sometimes it is stacked at boot logo and more often it is stacked in Android logo. I need to switch off radio wait 30sec (acc delay set by myself) and restart radio again. Yusually it helps and radio loads properly second time.
[Android Head-Units] Michalec:
I had to use reset button two times. Once when screen was turned off and nothing worked (stopped working when using reverse camera) and second time when screen was distorted (after reboot everything is fine). From my side it's more stable that my old HU.
[Android Head-Units] pinotuning:
sometimes I turn on my car and the radio starts and steering wheel do not work and the key light remains off ! sometimes it remains black screen...

to resolve momentarily I have to remove "delay" turn off the car and everything goes back to work .. seems to be an absorption of the battery and my unit in tilt ! my battery is perfect and this problem was not with the old unit
[Android Head-Units] MarkOrkenyi:
Just thought to share my finding with you guys.

Using spotify i was unable to get an okay-ish sound quality from the HU, but with the radio app it was kind of okay.

By launching spotify first, THEN launching the radio and switching back to spotify the sound becomes much better. (I'm using EQ for both apps, but that's not enough)

Seriously, i think they used monkeys to develop the software for this...
[Android Head-Units] donbrisko:
For the case anyone wants refund aswell via AliExpress:

They offered me a full refund without any discussions after describing the random crashes and software issues I experienced.

Don't want to bother myself anymore with all the issues or wait until a custom rom has been released.

Actually I was suprised that there are other MCUs apart from the MTCx ones - bad experiment.
[Android Head-Units] starfarer:
I recently bought one after bricking my other HU. All seems fine and much faster on everything compared to old unit. Few issues:

1) The harness provided lacks the connection for radio antenna pic attached. there was no manual so don't know how to connect. I'm using the harness from old HU for now.

2) Is there anyway to change theme on these? The notification dropdown is almost invisible due to having same or similar color of txt and background.

3) is it possible for some kind of plug n play external mic? if yes can you share link pls.

thanks.
[Android Head-Units] pinotuning:
you didn't specify anything! what model is your unit ?? mcu stm32? what car model do you have?
[Android Head-Units] starfarer:
oh thought it'll be obvious posting here will be for STM32 MCU. Sorry and anyway I bought it off ebay as it was available within EU zone and price was similar without the worry of custom charge. Unbranded as can't find any kind of name anywhere on the box or unit itself. The about screen:

[Android Head-Units] Hol47:
Has anyone managed to allow these to sleep overnight and boot up quickly the next morning?
[Android Head-Units] pinotuning:
strange that kind of antenna cable! never seen in my life .... in the wiring of your unit you should have a jack cable to put microphone! there is a female jack on mine,

unfortunately you are right The drop-down menu of notifications is almost invisible and it is not possible to resolve for now ... we are waiting for a custom firmware!
[Android Head-Units] starfarer:
Thanks. Received reply from seller and he has provided where external mic need to plugged in but gave link for 3.5mm mic products. As for antenna harness which is missing, I've attached pic. I can cut it off my existing and spare harness but don't know where does that blue wire connects to.
[Android Head-Units] pinotuning:
the blue wire is usually a + 12v electric antenna or antenna amplifier to be connected to the blue wire of the radio on the iso connector! do you have ISO connector?

New files from Ali

Just got a firmwareupdate from Ali;

this one "os_update_KC1E0113-P01-1.1.4.3.1_20191221_143639.zip" which is here;

https://mega.nz/?spm=a2g0s.imconver...L!dIHCO1mhiThFOfs4d2riJhSIUFyQ5LK1T6BYj3pvj4k

and this one "mcu-201910281001KC6-1453.upd' which is here;

https://mega.nz/#!S5QFRSKK!qhs0yTKRdoAfHl28vqYHwz2B3eS0IoM7-b20-1a4bcE

Got these because I complained about the unit not remembering radio presets or equalizer settings.

It does hold wifi and bluetooth, though and also where I left the music playing on USB stick.

Will try and update this weekend.....

I bought the boison unit with Android 10, advertised as 8-core. There are some apps I cannot reach: SWC and Car logo changer for example. Anyone knows how to get there?
[Android Head-Units] Michalec:
Try searching for it in factory settings. Tap OS->Kernel 3 times in About phone. But I'm not sure if it's the same on Android 10.
[Android Head-Units] Endurance99:
figured it out. There is a car symbol on main screen in the lower left corner. There I can get access.

Thanks.

But: I don't get any other MP3-Player app to work. Poweraudio Pro can't find anything whether it's sdcard or USB Stick. Winamp too. Freeamp finds all songs, but cannot play. Man, that is really rubbish.

[MENTION=644758]malys[/MENTION]k: Will your mod support Android 10 devices too? (Perhaps downgrading BL?) Thanks a lot for your efforts.

While I uploaded the video, there are links to downloading firmware in the description of the video. Do not mistake! There are 2 types of firmware - with a DSP sound processor and WITHOUT DSP! In the archive along with firmware there is an instruction!

Can someone confirm of this fixes the auto sleep issue I would really appreciate it.
[Android Head-Units] rudix78:
Installed lite version yesterday, works like a charm. Beautifull launcher. For me key problem with Chinese ROM was that it not always started and freezed. We will see if this wil be solved. Regarding acc delay it worked for me on original software so

i don't know if it helps to others with delay not working properly. big step forward, it looks really professional now.
[Android Head-Units] DeVolga:
Hello dear! Is it possible to somehow upgrade from version 8 to version 9 of the android to take advantage of your work? I would be very grateful for the help. Maybe you can somehow contact for this (maybe 4pda) for this?
[Android Head-Units] Endurance99:
Hi Malasyk,

at first a very big thank you. Donated today and full version is great. Nearly everything works as it should. The next days i'll install rear cam. There is one thing that is bad at stock and i don't know if you can fix it. I have that blink 161 BT Module and just one device can be connected at a time. But that is not all. My garmin HUD not the Hud + cannot be paired. Device is shwon shortly and as soon as i tab on pair, HU tells me it's trying to connect for about 5-10 seconds. Then message disapears and Garmin HUD as device disappears too. That is even, when Garmin is the only device available. And it is only shown in stock BT search, not in yours under connection -> bluetooth. Under your Mod settings i can neither name the HU nor can i connect anything as bt search is always empty.

Again thanks a lot. Really appreciating your work.

/Edit:

By the way: RDS works really smooth on your rom or radio application. The first time I see station names on my device. Did you adjust the AF algorithm? Maybe it's just imagination, but I think, that device does not make a hard "disconnect and reconnect" when switching to alternative frequencies. At least I didn't realize.
[Android Head-Units] Malaysk:
Service firmware for devices without DSP, who mistakenly installed firmware for DSP and lost sound.​

Install only to those who can not return the sound !!!​

Based on my LITE mod for devices without DSP with full Root access and a modified launcher.

ATTENTION: after the firmware, everything will be reset for you - the touch will become mirror and will change LEFT-RIGHT. The buttons on the panel will not work!

And maybe all the settings of the device will be reset. You need to rewrite all your settings as they are put on a piece of paper or take their photo.

After flashing, you need to configure the touch and configure the buttons again. I am enclosing the photo below where it is located. Go to Settings - Car-related settings - Setting the touchscreen and button on panel. As you configure, you need to reboot.

I want to warn you: everything that you do, you do at your own peril and risk, and you decide whether to do it or not.
