Hello,

What do you mean when you said it still repeats the code 3 times ?

When the multiple key-codes delay is activated, the logs still continue to print the keycodes 3 times, it's a normal behavior.

But when you press the next button, do the player skip 3 tracks ?

And of course, this option only works if you are using a 3rd party player, not stock player.

hi

Hi guys,

Just got two "2Din pure android 4.2" radio unit for both familly cars.

In my Kia ceed I have this one:

Ok, can't put picture or link, as I'm a new user...

Will show you in a few post.

It looks like the huifei you are talking in this post, I am going to take some picture of the menu to be sure.

And this one in my wife's car, a KIA Carens:

Ok, can't put picture or link, as I'm a new user...

Will show you in a few post.

This one looks different, can't change button colour, but contrary to the first one it plays radio as soon as it start. (cool feature)

I am going to take a few picture of this one.

Hope you can help me identificate those two bastards, because I'm very interrested in tweaking them.

I'm pretty happy with the product, but there's lot of room for improvement.

Just go to the "about" screen in "settings" as on any Android device and it will say the MCU version which tells you the manufacturer.

I dont know what theyre playing at - your version has no ADB, other versions dont have proper bluetooth . . . assuming other version of the KGL and KLD 4.4 DO have ADB, has anyone checked I wonder ?

Just a thought - I wonder if your hardware is slightly different ? That could be a possible reason for the BT differences if not the unable to root problem, dont spose youve opened your unit up ?

Have you pm'ed coudu and asked him how he rooted it ?

Thanks for your work BTW :)
[MTCB Android Head Units Q&A] KeiserSozeyFr:
Did you try CarService before upgarding to 4.4 ? did it works ?

As I never had this problem, I don't really know how to fix it. But some people on this thread had same problem, please, do a search about it, I know somebody talked about changing the default music player.

You can try to uninstall all the 3rd party music players and install just one player (try poweramp first, I know it works with CarService)

On last resort, try activating option "ignore play state". But with this option activated, music will not be resumed after phone call, mute off, etc ... And it will not be possible to play with 'next' button when music is not playing.
[MTCB Android Head Units Q&A] coudu:
I did not root the unit "online" I pre-rooted the image by puting the files needed for root in the system.img.

If you we wanted to dump system.img, boot.img and kernel.img from a non rooted system the solution would be to build an update.img that would just flash the recovery with TWRP and no other parts, then from TWRP we could backup or dump system.img, boot.img and kernel.img.
[MTCB Android Head Units Q&A] Tung_meister:
I already tried 'ignore play state' but the same thing happened. I didn't try with 4.2.2 as I've only just bought the unit. I'll see if changing MCU makes any difference. Surely though if the app is detecting the key presses it has to be a problem with the app not correctly sending the next/previous track commands correctly?
[MTCB Android Head Units Q&A] webdude12:
Basically my idea. There is one thing that concerns me. There is talk about Touchscreen not working on TWRP, yet when I loaded the Rockchip 800*480 generic image on 800*480 unit before it broke. The touchscreen worked just fine. It just wasn't mapped to the right memory locations for the partitions, so didn't work. So I'm going to have to play with trying to build my own TWRP images, just don't have the time right now
[MTCB Android Head Units Q&A] KeiserSozeyFr:
In fact, I just send standard signals for next and previous. And it works with most people in this thread.

Try what I said about uninstalling all players and installing poweramp.

I don't really think it's a MCU problem if the key codes are displayed when you press SWC buttons.

Let me start over :o

I have CarService_2.0.2.apk installed on my KGL head unit. When opening up CarService and viewing the log on the left the key presses give me the following output when using the steering wheel controls:

The third party audio app i'm using is VLC

When pressing any of the control keys the input is repeated numerous times.

Key code are as follow:

VOL+ = 19 (repeated 3 times)

VOL- = 27 (repeated 3 times)

NEXT = 45 (repeated 2 times)

PREV = 46 (repeated 2 times)

MUTE = 4 (repeated 3 times)

I then applied different delays using the app, but this did not make a difference.

I will try downgrading the Kernel to 1.77 as suggested by [MENTION=456516]typos1[/MENTION] and see if that works. Now idea how to do this yet, but i'll read up some more. :D

I have JY HU. I have similar problem with SWC. If I use MTC app the SW left button make next command, the right button the previous command, these two buttons are changed. I don't modify this setting with Steering wheel key menu/app, because this app does nothing.

[IMG="SWC"]http://kepfeltoltes.hu/141121/20141119_152125a_www.kepfeltoltes.hu_.jpg[/IMG]

Do you see the Steering wheel key menu/app yellow button icon, can you redefine the button to command on your HU?
[MTCB Android Head Units Q&A] Tomcsyy:
You have right. :( The HU connected to the obd reader via bt (in the upper statusbar shows the obd logo) but the torque app doesn't see any bluetooth device. :(

---------- Post added at 10:55 AM ---------- Previous post was at 10:50 AM ----------

Is there anybody who can use the Spotify with the SWC?

For me doesn't work. My SWC works perfectly with Music and Poweramp, but with Spotify nothing happen.

Any idea KeiserSozeyFr? :)
[MTCB Android Head Units Q&A] Tung_meister:
How is it possible if you send the standard commands for it not to work. If the toast displays the correct correct command the button has been correctly intercepted so it has to be an issue with the app doesn't it?
[MTCB Android Head Units Q&A] KeiserSozeyFr:
The "Steering wheel key menu " (on your screenshot) is only to define the buttons when your car don't have CAN-BUS.

I think there is something wrong about you MCU configuration. There is a configuration file on the HU to redefine the buttons, please make a search on this thread about it.
[MTCB Android Head Units Q&A] typos1:
I dont understand your problem.

Just update the unit to Android 4.4 (DO NOT change the MCU unless you have a JY MCU update image - MCUs cannot be changed to anything other that an MCU version from your manufacturer, any Android version can be flashed, however, this is in the guide on the first page)
[MTCB Android Head Units Q&A] KeiserSozeyFr:
Ok, I will explain how CarService works :

When some buttons are pressed (next, previous, play etc...), CarService catch the events and get the code of the button.

When it receive "next" key code, It send a standard signal (broadcast intent) to the system to request for jump to the next track.

The default music player supposed to listen to this signal and execute the request, i.e. jumping to the next track.

Same behavior with previous, pause and play buttons.

I don't know if VLC listen to these signals or not, but I know it works with Poweramp and N7 player as I already tested CarService with these apps.

It seems that, when several music players are installed, these signals are not triggered from the player we expect. And sometimes, from none of them !

If the "key code filter time" is activated (not null), when a key code is received, the signal ("next" for example) is send on the 1st reception, after this, all the keys with same code are ignored until the defined time is elapsed.

Purpose of CarService is not to override the received key codes but to catch them in order to control a 3rd party music player. that's why you will continue to receive the key codes events on the logs, even with filter activated.

Vol+ , Vol- and Mute are not managed by CarService as these buttons are supposed to work from SWC without CarService.

The key code filter will not fix the "multi key-code" bug, it's just a work-around to avoid the tracks to be skipped several times.

So, what happen with VLC when you press next button on SWC ? nothing happens ? 3 tracks are skipped ?

I was planning on installing the latest KK version last night but wanted to make sure I could get into bootloader.

The screen is black but doesn't seem to respond to the power button.

Is the device installed correctly to the computer - should it show up as "class for rockusb device" in my device settings?

Or use USB to OBD, its faster and more secure, reflash 4.4 and see if the BT with phone problem persists, if it does, downgrade as uncleg says. The BT to OBD is a known problem, we (and hopefully the manufacturers) are working on it, the BT stopping altogether has not been reported by anyone else.

I got shuttle music player to work with the steering wheel control (SWC).

First after installing kk_ pre_rooted_preparted_v2, i installed com.dr8.xposedmtc_v148_cffb82.apk then i installed de.robv.android.xposed.installer_v33_36570c.apk.

second step, i updated the framework module.

third was to install the CarService_2.0.2.apk. open the app and click the ON in the top right corner.

press vol up (+) 3 times, Press vol down (-) 3 times.

press next/seek down (\/) 3X and prev/seek up (/\) 3X times and watch the numbers on the left side of the screen.

while you are doing this, the music player should start to play music, and when you press next or previous it should change the songs track.

Now open xposedmtc and pick the music app of your choice and set it as default player.

either use es file explorer in super/root mode or root explorer app to access /System/App/MTCmusic4.apk and rename it MTCmusic4.org, do the same with music4.apk---> music4.org

reboot your system.

make sure your sd card has atleast 2 songs then start your music player (in my case i am using shuttle music player from the google play) and you should be able to control it with your SWC buttons.

hope this helps someone :D
