Cannot sync contacts from phone to HU via bluetooth

Hi All,

I'm Marc, newby here on XDA (and still a bit of a noob...:rolleyes:)

I hope somebody can help me: I've downloaded the new Malaysk MTCD rom on my Joying 5.1.1 HU. Everything seems to work OK except for 1 thing: I cannot sync my contacts from my phone to my radio using bluetooth(I'm using a Oneplus One phone on Cyanogen software (6.0.1).

I click the double arrows in the bluetooth app on the HU but nothing is syncing. In Xposed installer there seem to be no modules I can uncheck.

Can somebody help me out?

Thanks in advance!

For me, MTCD_LM power button doesn't work propperly.

Sometimes after sleep i only do get black screen, music etc playing controls working.

Pushing power again shows "shutting down", changing volume with rocker is displayed. nothing else until i do force a reboot.

Anyone else?
[MTCD Software Development] karmacop:
Seems that the JY SWC app doesnt work in V5 for some reason, service says its running but doesnt interact with Poweramp at all. Also did a reboot of the unit and lost my radio stations for some reason. :/
[MTCD Software Development] masri1987:
works fine for me and power amp, i did a clean install though
[MTCD Software Development] karmacop:
That's weird, maybe i will try clearing the data for the app and see what happens.
[MTCD Software Development] f5f5f5:
This is most likely not a network issue, but a long standing TomTom GO on Chinese HW issue that can't handle device ID's longer than 12 characters. Change your serial number with Xposed and it'll work. ( source ).
[MTCD Software Development] pitu120:
In v5 You added app " JY SWC app" I can bind my stering wheel keys and it detect it fine. Is it possible to use it in spotify? :)
[MTCD Software Development] masri1987:
the app is only for poweramp.
[MTCD Software Development] pitu120:
I know but if is possible to control this app from stering wheel, isnt possible to control spotify?
[MTCD Software Development] deedeebulldog:
Malaysk,

I have an MTCD and MTCB unit. I noticed on your last MTCB update I could dial in a radio station and also save the stations if i had to reset. Is this possible with the MTCD or is it something you could add later?

thanks mate ...always done several times, it doesn't change the ID (upgraded to v 1.53 Pro too). I will try several times hoping well.:confused:
[MTCD Software Development] karmacop:
I manually re-installed the JW SWC app over the top of the baked-in version and the steering wheel controls for Poweramp now seem to work. Must have been something to do with the semi-data wipe that happened when I upgraded from v4 to v5.

Hi, on your cell phone in your bluetooth settings, look for your paired head unit and click the small "gear" icon next to it, look if contacts sharing is authorized.

Hi. i m new. Just recieved my 10.1" joying 5.1.1 unit. Can i install V5 rom on it. Is this better than the stock one it comes with.?
[MTCD Software Development] stbeut@yahoo.fr:
Hello.

Really better than genuine one on my 5.1.1 7" Joying unit.
[MTCD Software Development] HVB83:
I have a KGL unit, expect it won't be much different from Joying. At least not in the beginning, when all suppliers are rushing to get their 5.1.1 units out.

The Malasyk firmware is a very, very big improvement over the official one. Much faster, way less bugs and more options to play with on top of that.

Keeping in mind also that this has only been worked on for 2 months or so, we hopefully have even more goodies to come!

My question is if I can install this firmware .It is that I do not really understand the issue of .mcu

Thank you very much.
[MTCD Software Development] stbeut@yahoo.fr:
Hello,

this firmware works on all MTCD RK3188 units.

Don't change your mcu: it is tied to your hardware (each company tune the hardware to their requirements: buttons or not....).
[MTCD Software Development] albertito00:
Ok. Then, I have to put the image on the micro SD and install it from the recovery , right?
[MTCD Software Development] avionaru:
Yes, choose the third option from the menu, as instructed in the document you downloaded together with the image. I just did it 30 min ago and it works fine.

You can update your MCU if you find your corresponding one in this list: http://xdaforums.com/showpost.php?p=61291848&postcount=14139 . Apparently there's a MCU version with quite a jump from our v.1.53, maybe someone can confirm we can install HA-BN v.2.85 from that list.
[MTCD Software Development] albertito00:
Thank you very much. Regards
[MTCD Software Development] zoppa:
Don't use them, these MCUs are for MTCB devices.
[MTCD Software Development] Dec64:
How do you update the MCU? same way as you install this rom? Would i then need to reinstall this rom over the top or will it be a updated MCU with Malaysk's rom?
[MTCD Software Development] zoppa:
Exactly, file name is dmcu.img.

Oft course, only flash MCUs that match your manufacturer/OEM and device class MTCD.

B -> bad, D -> dope! ;D
[MTCD Software Development] ikerg:
I did read that ha and bn were compatible...

I have just received my 2din universal MTCD from hotaudio as well but mcu firmware is 1.63

You can ask for a mcu update to hotaudio or somebody to tell me how can I backup the mcu firmware image from my headunit in order to share and create a repository for mcus with some kind of description about the change log

Are mcus compatible between MTCB and MTCD? The corresponding thread says that there are compatible between rk3188 and rk3086...but nothing related to MTCB and MTCD

For your information I have MTCD_HA_1.63c

Thank you very much! This did the trick indeed. Contact are now syncing OK! :good:

Imho, you should read this thread from begin to end. If someone says B and D MCUs are exchangable, than ask there.

Or just try it and report, if it did work. [emoji48]
[MTCD Software Development] Dec64:
The widget on the main menu to control the radio never works for me? It displays the correct frequency but the buttons do not work. Also, when i scan for FM stations, it never saves them, when i come back to my car later they are all back untuned? Is this a bug or is there a way to save them permanently ?

I think it's a new behavior with Android M 6.0

[MTCD Software Development] trap63:
Malaysk is on hands to solve this trouble, wait next release. Otherwise you can try to solve with Serial Id Changer (if on your unit runs). If your serial may save up to 12 digit, GO runs.

I have serious issues with v5 on my GS unit (Xtrons PF85MTVA). Spontanous reboots, loss of key function (need to hard reset), cannot activate WiFi (need to hard reset) and one spontanous wipe (!), so far.
[MTCD Software Development] Dec64:
I have a GS Xtrons unit too, using v5. Just used my card today to be welcomed by booting into a full wipe?

Not had any loss of function on the keys yet or wifi issues.... Hopefully the wipe does not happen again as it's not fun to redo all the setup.
[MTCD Software Development] hadeone:
V5 is somewhat buggy for me. I keep getting "JY SWC Service has stopped", "Google Play Service has stopped" and the brightness randomly goes to the dimmest setting often. Also Waze is unbearably slow with the last few versions of this ROM. It actually seemed faster with the stock rom. Now it take a long time to start up, goes to a black screen sometimes and freezes and is slow to open the keyboard. Runs fine once it gets going but doing anything in the menus slows the whole unit down. Any ideas?
[MTCD Software Development] HVB83:
On my unit this method doesn't work either. Hoping that Malasyk is able to resolve this soon. ?

---------- Post added at 05:49 AM ---------- Previous post was at 05:42 AM ----------

I had the black screen after wake-up too, but that seemed to be related to JY SWC. I've now turned off the autostart for that and now it seems fine again.
[MTCD Software Development] hashtowent:
hello hvb83,

what autorun-manager do you use? The one preinstalled is russian only!

thanks!
[MTCD Software Development] samm000:
hi, i have a r16 quad core, mcu MTCD. I'm running now on 4.4.2 can i savely update to 5.1.1?

Regards
[MTCD Software Development] HVB83:
I won't have access to my unit until tomorrow, but if I remember correctly, there is indeed an app in there which is called autostart, but is in Russian.

The system configuration now has a menu option called "autostarts" or something. All app that are allowed to execute after system boot have a tick box saying "has allowed". After unchecking the JY app, the black screen after cold boot has vanished.

Anybody got a solution for assigning the hardware buttons to Poweramp instead of the standard music app?
[MTCD Software Development] raceart:
I have the same problems, I will wait for the v6, for the moment I'll come to the stock firmware. kgl 1.63.

I think the problems started when I've changed the status bar settings. (but I'm not sure)
[MTCD Software Development] masri1987:
Flash V5 of this rom if you want 5.1.1
[MTCD Software Development] mpalastea:
hi guyys,
[MTCD Software Development] zoppa:
Could you please read this thread from the beginning and use the search? Don't get me wrong, but this is not the "ask basics and get a step by step walkthrough" department. Do your homework, as we all did as well.

Thank you.
[MTCD Software Development] sterod:
I would ask the manufacturer before you do that. If its anything like a Joying device, you CANNOT go from MTCD 4.4.x to MTCD 5.1.1 without a hardware update. And no, I do NOT mean MTCB 4.4.x to MTCD 5.1.1. I remember reading about someone who had purchased the Joying 10" MTCD unit on the Joying Forum and it had shipped to him with 4.4.4 installed as at the time, Joying still didn't have 5.1.1 working 100%. He was quite disappointed that Joying told him he needed to purchase a hardware upgrade to get 5.1.1. So, be careful here.
[MTCD Software Development] masri1987:
I had no idea a hardware upgrade is required to run 5.1.1 on MTCD.. i didn't even know there was KitKat MTCD units.
[MTCD Software Development] sterod:
That's not surprising as there were very few MTCD units shipped out with 4.4.x. It was these early adopters that got screwed. For Joying at least, they sent the owner's the parts but they had to pay for the shipping. Gotta be sure before you hand out advice :)
[MTCD Software Development] samm000:
A have read it, but it should be possible to port over a rom.

I dont know if my radio is like a joying device, the specs of my radio are R16 allwinner sun8i, manufacture TW, mcu 5.3.18 (the manufacturor say its MTCD)
[MTCD Software Development] ikerg:
Some strange .. if it is allwinner it is NOT a rockchip device as are all the MTCB and MTCD units here covered (rockchip rk3188)

So the manufacturer is not telling the truth.

You have to go to device information to see if it is a mtcd or not.

Edit --> it seems that your unit is covered by this forum

[MENTION=3590033]Malaysk[/MENTION] since the Bluetooth problem is still ongoing is it possible for you to modify the ROM so that it will accept a second Bluetooth device, such as a USB Bluetooth dongle so that maybe the applications we are having problems with that think bluetooth is off can connect to this secondary Bluetooth adapter rather than the one on board that is causing all these problems
[MTCD Software Development] samm000:
in the system info i see mcu 5.3.18, i have an account at 4pda (http://4pda.ru/forum/index.php?showtopic=721863&st=1560)

i have allready try some roms, but i want to upgrade to 5.1.1. I have mailed with the manufacturer about the mcu and he told me that it is a MTCD.

It should be possible to port a 5.1.1. rom to the R16 allwinner and rockchip rk3188.
[MTCD Software Development] Dec64:
Another complete wipe of the system this morning on v5....very very annoying. Hopefully this can be solved soon?
[MTCD Software Development] l0aded:
Maybe a nub question but I just want to be very sure before I root and rom.

I purchased and installed a Joying 5.1 Toyota (RK PX3 1.6GHz Cortex A9 Quad Core, Resolution 800*480)

I assume it is MTCD since it is 5.1.

Can I install this series of roms on my HU?
[MTCD Software Development] mpalastea:
Hi zappa, thanks for your kind advice. I already have read this thread from beginning but I didn't find answer to what I need to know, so I asked. If you would be so kind to point me to where I find answer for my question I would be very grateful to you. I also asked my seller where I bought this unit, but he couldn' t tell me, so I hoped I would find help on this forum, and not " smart" answers. After all, that what forums are for, right? ..discussions and support for others..". Thanks in advance for your upcoming assistance.
[MTCD Software Development] ikerg:
Don't assume.

Just go to "device info > version info" and see by yourself.

[MTCD Software Development] nvertigo:
so ANY headunit, as long as it says MTCD, is applicable to these roms?
[MTCD Software Development] ikerg:
Initially yes...but only the ROM...not the mcu because mcu is dependent on the letters after MTCD

In your case you will have MTCD_xxx_yyyy

Xxx is the manufacturer for the mcu....only mcus for the same manufacturer are interchangeable

Wish List

Here are the following things that this ROM (and MTCD 5.1.1 devices in general) need to be perfect (in my opinion, of course)

1) The Bluetooth bug fixed which affects applications that communicate directly to BT devices that are NOT paired with the head unit. These apps are told that BT is off (when it isn't), and show a permission request popup to allow it to be turned on which results in the app hanging/crashing when selected. An example of this is an app named ALPConnect which I use for laser and radar warnings. This app communicates via BT directly to the BT dongle attached to my radar detector which is not (and should not) be paired with the head unit.

2) We need a way to backup and restore the radio station presets which for some stupid reason are stored in the MCU instead of an XML file on the NAND. Its ridiculous that the presets are lost any time you "touch" the MCU settings, such as by re-assigning steering wheel control keys, or accessing the factory service menu.

3) The JW SWC Service app modified so that it can pass on the steering wheel controls to any multimedia app, not just Poweramp. I use Doubletwist for my music and nothing I've tried has made it able to respond to the steering wheel controls, I think its the INTENT's that are wrong.

4) A 2-3 second shutdown override so that the head unit does not go into a "Shutting Down" state when the 12V Accessory power is temporarily lost, such as when cranking the ignition if the head unit was already on.

[MTCD Software Development] Dec64:
This is crippling now.

Started my car to travel to work this morning only to get the same thing. Android man saying "erasing" a reboot into "starting android apps 1/55" for it to finally load into a clean wipe.

I did do a Titanium Backup this time, and when I went to put the backup it said the devices ID had changed due to a factory reset or similar and I needed to change that back as well. There are some really bad issues atm:

1) Radio NEVER saves presets at all. always have to retune.

2) Random wipes of the entire device (with no obvious cause, All I did yesterday was install a new app, no root, system settings ect)

3)ODB bluetooth as reported already by many.

4)Startup options never seem to work. appears to boot into maps sometimes, sometimes not.

Also boot times are slow, including the time you have to wait for the UI to become responsive enough to use

Any at least have any fixes or advice on these issues? I may try reverting back to stock and see'ing if that helps.

I also experienced an issue with my unit restoring itself to factory settings. Running the 06292016 build w/ V1.65_1 MCU. I did have the unit rooted and had previously received a notification about malicious software or something like that, so I was wondering if perhaps the self format and restore was related to that.

I am having an additional issue I was wondering if anybody was experiencing. Bluetooth audio quality when playing music through Bluetooth music app is crap. Sounds like audio files are being transcoded on the fly to 96kbps, so much audio artifacts it makes you wanna slap your mama.

Would make a new thread about that but cannot due to post count. Anyone know what's going on with that?
