I have been thinking about buying that one too. Only problem is that my radio has a double fakra connector. So the wire trough the car is probably fakra also. Seems a big job to replace the antenna and wire

Hi,

I have upgraded the software in the headunit (CAN+MCU+system), but problem remains. With the newest master piece release, it still stutters even when running in foreground. I have checked that "Show notifications" is enabled, but no notification shows in the pull-down bar at the top. It even asks for USB access every time it starts. I am concerned that the unit is running a too slow hardware, the A31 is rated at 1200 MHz and 4 cores, but according to AnTuTu it only runs 749 MB of RAM and has a total score of 16000 which is low end. I find it stange as this is a new 10.4" unit with car-specific connections and adaptions (BOSE fiber optics and stuff). Is there a way to figure out if the DAB+ program is using too much resources?
[Android Head-Units] Chevy68:
This is my first post and I had to join after discovering this thread! I have just fitted an Autojeta unit (Octa Core, Android 6.0) which came with USB DAB+. Install went great and unit runs perfect, except for poor quality and basic DAB+ app. I also got the skipping, stuttering playback when I tried to run DAB+ in the background. This was all solved once I uninstalled the supplied DAB+ app and installed zoulou's Masterpiece! What a great job!

I only have one issue and question. How do I get Australian Station Logo's? Looks very boring without any logo's!

Thanks to zoulou once again!

DAB reception great one day, terrible the next...

Hi all,

I'm using zoulou's brilliant app as well, and its all been fine until yesterday when the reception went to s**t. The reception was good for a few days, but last night driving around Manchester it wouldn't stop making all the horrible DAB burbling noises. Can bad weather affect DAB signal perhaps? Or is it something else?
[Android Head-Units] astra gtc:
i thought these dab modules didn't work with amplified antennas?????
[Android Head-Units] GO-R:
I too have had this issue. Has been working for a few weeks perfectly and then a few days ago started to get bad reception again. I am in Australia. Any ideas?
[Android Head-Units] hans.vinkers:
The fm part has double fakra. The superbat antenna has din

[Android Head-Units] Helgeo:
The module does not care if the antenna is amplified or not, and will work very well with an amplified antenna.

However there is no phantom power from the DAB+ module so one must add some kind of power inserter to achieve this. I'm currently using a cheap DVB-T power inserter powered from one of the USB ports on my head unit. There are also dedicated 12V power inserters that may be better to use as the USB port may not provide enough power for some active antennas.

How to create my own station logos

You have to collect them yourself, and copy them to /mnt/sdcard/DAB/logos/user (or similar) on your head unit. If you use a file manager, the path may be DAB/logos/user instead. Make sure the alphanumeric characters (case insensitive) and any '+' character of the filenames match the respective station labels. PNG and JPG formats can be used. After that, you go to the settings and SYNC the logos.

For instance, for the station "ABC Jazz" you can download the image http://www.abc.net.au/cm/lb/8785730/thumbnail/station-logo-thumbnail.jpg and save that as ABC_Jazz.jpg. And so on. I prefer using underscores for blanks. Blanks in filenames have a tendency of creating trouble in some circumstances.

I have done this myself for Norway. You can look at my latest collection as an example:

https://www.dropbox.com/s/ouo4dskp76am9jk/NOR_DAB_20171129.zip?dl=1

Good luck,

Egil

What am I doing wrong? A lot of times the dab app starts in the background when I was running music since the last time I had the radio on. Should I have installed the nousb version?

Verstuurd vanaf mijn Z2 Pro met Tapatalk
[Android Head-Units] Chevy68:
Thanks very much, I now have station logos!

However, I have become aware of a problem with the Masterpiece, well more an annoyance really. Before I installed the app, the head unit would automatically start the last open app when the car is started (typically the FM radio in my instance) and immediately start playing. Now everytime since I installed the Masterpiece, at power on the head unit goes to start the last open app as normal, but after a second or two, "DAB+" flashes on the top of the screen and the unit then goes back to the main screen. I then have to manually launch Radio, Media Player, whatever and all works ok. Like I said, more an annoyance than a problem, but annoying nonetheless. My guess is the DAB+ App launches in the background when the unit powers on, which shuts down the startup app. I have checked all the settings and I cannot stop this from happening. The option to automatically launch the app when it detects the USB DAB is switched off also.

Can anybody shed some light on this?
[Android Head-Units] egilkv:
Did you try installing ZOU-DAB+171119-nousbdf.apk?
[Android Head-Units] astra gtc:
can you show your full setup and post some pictures for me please?
[Android Head-Units] egilkv:
I do not think you can make any assumptions about how good the core of your unit is based on anything other than hard facts. Perhaps you could install the "Hardware info" app and tell what is says under System, Processor and Memory?

I do not have any hard data on what is good enough or not, though. My guess is that 1200Mhz and quad core should be plenty good enough, but possible your unit may be low on memory. I do not know for sure. I have a Joying unit based on Intel Sofia with 2GB where the DAB works fine. I also have another unit based on Allwinner T with 1GB, and here the audio stutters. Both of them report around 15% CPU load when DAB is running.
[Android Head-Units] binar1:
Firstly this masterpiece version is a great improvement over the stock app however after testing for several days I have the same problems that others have reported.

1. Dab+ app playing along with other music apps.

This seems to be related to the run in background setting. Once turned off problem is gone.

2. Poor sound quality, digital static.

I've had this a couple of times. Closing and reopening the app seems to sort this.

3. App closing and reopening every few minutes.

This is my biggest problem, on a 15 minute journey to work that app has done this a dozen times no changes to any of the settings seem to help.

Video to show the issue.

I have a non rooted xtrons head unit with a xtrons Dab+ usb dongle and a roof mounted powered aerial.

Any help with things to try would be great.
[Android Head-Units] Chevy68:
I installed this version and it fixed the problem! Thank you very much!!! :good:

Can anyone tell me if it is possible to control the volume of the DAB+ independently? For example, if I adjust the volume of FM Radio at the desired level, and then switch to DAB+ it is barely audible. If I then adjust the DAB+ volume up to the desired level and switch back to FM Radio, BAM! Too Loud! My old WinCE unit had a level mixer to adjust each source so they were all roughly the same volume level. Is there something similar for DAB+?Android 6?
[Android Head-Units] egilkv:
I am not aware that the DAB+ app has a setting for volume. But perhaps you could try https://play.google.com/store/apps/details?id=com.spycorp.appvolumecontrol&hl=en or similar apps?
[Android Head-Units] delray70:
Thanks [MENTION=7838245]realzoulou[/MENTION] for your reply, both issues are not a big pain, I just wanted to give you some feedback. I'm developing apps for my own and made the experience that the users use my apps differently like me, so I never noticed some of the issues they have.

Did you change the way you're scrolling in the listview to the 170909 version? Using this version, scrolling is much faster and less noticeably.

[MENTION=8753210]astra gtc[/MENTION]

I also have the astra gtc 2012 , and the DAB+ with amplified antenna works perfect
[Android Head-Units] astra gtc:
my gtc antenna is the factory fitted sharksfin. i only see a brown fakra connection at the roof..

however is see blue fakra connections at the back quarter pillar at the right hand side beside the boot lid

and there are black fakra connections below both back seat quarter panel windows...i think one side joins to the other side. there is antenna built into both windows here...

both blue and black fakra travel up and below the carpet along the drivers side where they go into some box under the drivers legs...

i don't get any dabs signal when i connect the antenna at the radio on dash to the android ...nor if i use adapters to connect up the dabs module............only a faint fm signal

so I'm stuck at where the signal goes to ,from the factory fitted sharksfin
[Android Head-Units] realzoulou:
You seem to reproduce this easily. If you could root the unit, install SysLog from PlayStore and capture the traces using SysLog right after this happened, I will look into the logs and maybe see what is going wrong. The audio beeps in the youtube video shortly before the app restarts are strange. Does this always occur shortly before the app restarts?
[Android Head-Units] realzoulou:
No there was no change. But the station logos of course make a difference. For a quick test you could disable the station logos in the list in Settings. I expect that this speeds up scrolling.
[Android Head-Units] Rick V:
I had the same problem. I took off the sharkfin (GPS antenna, your FM antenna is in the side windows) and replaced it with the DAB+ / FM antenna..

Auto start

Hi There

Great app thanks for all your time and effort.

I've got this app installed on a Xtrons pcd760loa-b running android 6 marchmallow. It's all setup to autorun on bootup but for some reason on bootup it runs for a few seconds then when the main menu screen comes on it stops.

Any help would be much appreciated are there any other android settings I need to look at to keep it running?
[Android Head-Units] WILLJE:
Anybody got any ideas how to solve the above.
[Android Head-Units] binar1:
Which version have you installed the normal or no usb?
[Android Head-Units] realzoulou:
If you have rooted your device, please install SysLog from Playstore and take logs right after this happened at startup. Send me the logs or attach them here. I will have a look then.
[Android Head-Units] realzoulou:
Because another user shared SysLog traces with me, I think I found the root cause also for your issue.

It seems that since I finally fixed the "Connecting..." issue, a new type of issue in the App comes to front, which I cannot fix because it is inside a native libdab.so library.

This behavior that you noticed starts when Android detects a Configuration Change (e.g. when a 3G USB modem registers with the mobile network). Then it currently re-starts the DAB App. However some crappy code inside of libdab.so cannot deal with this and crashes (maybe even invisibly to you).

I guess I can work-around this in my next release.
[Android Head-Units] WILLJE:
Device is not rooted but if it helps my problem I can look into rooting it. would you have any links to show how to do this.

---------- Post added at 02:18 PM ---------- Previous post was at 02:12 PM ----------

It's the normal version which as far as I know it's setup to auto run. Has previously stated it does start on bootup but then stops when home screen starts.
[Android Head-Units] realzoulou:
No, sorry. I give no hints for rooting, because every device is different. I am glad that I found posts from other great forum members that showed me how to root my Joying Sofia.
[Android Head-Units] typos1:
For help with rooting you would need to know what unit you have - Xtrons are a seller, there are no "Xtrons" units - they sell units from a variety of manufacturers, to find out what unit you have look in settings/about device, the MCU will tell you who manufacturers your unit, post the MCU and people will be able to tell you where to look for advice on rooting your unit.
[Android Head-Units] WILLJE:
MCU is

5.3.19-36-81-E50201-170104
[Android Head-Units] typos1:
Ok, you definitely DO NOT have an MTCB/C/D/E Rockchip/Intel unit, or an Intel "009" (Joying Sofia) unit, I can tell you that much.

You need to look in the Android head unit general section for threads with units with the same type of MCU you have (dont bother looking at the 009 Joying Intel thread and dont bother looking in the MTCB or MTCD forums as you dont have one of those units).
[Android Head-Units] WILLJE:
Processor type is quadcore-r16 is this any help.
[Android Head-Units] typos1:
Ok, that will help you find what unit you have - the R16 is an Allwinner processor, so you need to look for a thread about Allwinner R16 units with similar MCUs to yours.

THANKYOU

Just thought I post a THANKYOU to zoulou for all his hard work on the app, I first installed an older version of it several months ago and was instantly impressed. After a few weeks of using it I posted a few request for a future revision on this thread but no one including zoulou posted any comments about it so I felt a little disheartened. Last week I checked back on the thread and noticed a new version had been posted. I've downloaded and installed it, WOW! a massive improvement on an already great app with pretty much everything I had asked for included (and more). Unfortunately its not really the best time of year to be sitting in the car fiddling with car audio as its the middle of winter here in the UK with snow on the ground and temperatures below zero. I've downloaded the station logos via the app but had to do some manual downloads via my PC and transfer them via USB flash drive. I've still got a little bit of work to do with tweaks the some logo files but its not that important as I very rarely listen to anything but "Planet Rock". Thanks again zoulou.

Hi ive just installed my first custom Rom how do I install this dab app ant help appreciated
[Android Head-Units] typos1:
Put it on your unit via sd card or usb or download it via your unit and click on the app, it will ask you if you wanna install, click install.
[Android Head-Units] fsmotorsport:
Hi,

Thanks for the modded app, its a big improvement over the original.

However is it at all possible to fix the biggest problem I have with this USB DAB+ solution.

The problem is that when signal level is low, you get a horrible squealing broken up noise from the speakers. Why can the app not cut the audio when signal gets too low?

Is this a software issue or a lacking in the hardware?

The old style hard wired Klyde DAB adapter cuts the audio when signal is low. Just like any other proper DAB radio.

Unfortunately Klyde have opted to use the USB type adapter for all of the later head units.

I would like to use the old style adapter in my Klyde 7.1 unit but it wont even allow me to install the apk.

Does anyone know if it is possible to use the old style adapter in the new head units?
[Android Head-Units] typos1:
Possibly, but youd have to know which wires do what, but even if you found that out theres no guarantee it would work unless you knew what mods Klyde did to the motherboard to make it work - it doesnt work on earlier Klydes without the modification.
[Android Head-Units] binar1:
Finally got round to installing Malaysk ROM for 5.1.1 your app works a little better but still restarts every few minutes.

This rom is pre rooted so I have installed SysLog. How do I get the traces you need exactly?

Btw the beeps happened to be on the radio station at the time sorry for the confusion.

Big Thanks,

Brilliant it is fantastic.....just want to say Thanks for all the improvements and all the hard work, it really is brilliant.

Many Thanks.
[Android Head-Units] Olav_888:
Thanks a lot

I found over a friend this thread and I'm really happy. Good work, it's working perfect in my IceBox/Witson radio

But I'm cuming from a native DAB+ Radio and so I had a smal wischlist for future Versions:

- Failover to UKW, if the DAB+ signal is missed

- a list, which are show me directly Informations about Station, album, title

All other is perfect and on a high level for me
[Android Head-Units] harthoric:
I was wondering if there's a way to mute the high pitched static sound?
[Android Head-Units] realzoulou:
After the issue happened, open the SysLog app and press the "Take Logs" button. Then you either send the resulting tar.gz file to yourself via email, or copy it from the <internal SDcard>/SysLog folder manually. Attach the tar.gz file here or provide it to me somehow via a file hoster link.

I am currently working on that topic. I believe I can provide a solution for this topic.
[Android Head-Units] realzoulou:
a) DAB <-> FM Service Following : Not possible. The DAB App has no idea about the Radio App and vice versa.

b) Swipe the station logo or slide show picture to left or right and you will find some technical details about the current station.
[Android Head-Units] realzoulou:
I am unsure if this is a hard or software issue finally. But as I wrote above, I think I can provide a software workaround for when this issue occurs. I plan to "replace" the high pitch sound by "silence".

No, not possible. This App only works with the USB adapter with USB VID/PID = 16C0/05DC (decimal 5824/1500) ("VOTI", "Van Ooijen Technische Informatica", "shared ID for use with libusb", "wshtyr@126.com"). See Post#1.
[Android Head-Units] Olav_888:
hmmmm, then must implementet the UKW in the APP ;)

Ok, this is not so easy, I know

Informations: Tecnical I found, I had also see, that Artist and Title scroll througth the screen, only, if you had once a native....., but not necessay
[Android Head-Units] surfer63:
Actually it almost impossible.

Radio in these android units is always on. The standard radio app (non standard android app) can only read statuses, frequencies some RDS-data (on some MCU firmwares really incomplete) from the MCU out of that radio chip, and (un)mute it. It has nothing to do with the android layer the real android app and usb DAB implementation functions on.

Next tot that: It can be different for other chipsets like PX3/PX5 or T3/T8 or Sofia 3GR, etc.

Finally: realzoulou did some great improvements on the DAB app, but it is mostly reengineering of a Java app. He needs full source code access to the analog Radio stuff. He would also need full access to some native libraries (C/C++) (which are cumbersome to decompile and more cumbersome to read).

So if I realzoulou could make this work he would be a real champion (well, actually he is already :), but even more is required)

And no: I don't have a DAB stick in my unit.
[Android Head-Units] typos1:
What do you mean by "these Android units" this thread is about an app for generic DAB dongle that works on almost any Android device, plus there are 1oos of different types of Android headunits, many of which behave in different ways so a blanket statement such as "these Android headunits" doesnt make sense. On MTCB/C/D/E units the radio isnt always on.

This DAB mdule does not have FM capability (unlike the Shinwa DAB box that Klyde used to use on its MTCB/C/D/E head units).
[Android Head-Units] surfer63:
Yes, the radio, as in hardware, is always on. The radio app controls whether you hear it or not. It is a piece of hardware outside(!) the android layer, that switches on as soon as you turn the key in the contact, also in the MTC units.

And with regard to "almost any Android Device": yes, I know that, but maybe you did not realise you were in this (sub-)forum "Android Auto -> Android Head units". My reference to "these Android units" is far more accurate than the wildly inaccurate "almost any Android Device" of you. We don't discuss tablets phones or "almost any Android Device" in this (sub-)forum

Installing app on Joying DE-JY-UM124N2

Hi realzoulou

Will the app also work on the Joying DE-JY-UM124N2

Keep up the good work !
[Android Head-Units] typos1:
No, the MCU controls whether you hear the radio or not, not the radio IC itself - the MCU controls the radio IC.

I m fully aware what forum I am in, the point I was making is that this dongle/app works on any Android version from 4.0 up, regardless of whether we are in an Android head unit forum - this app will work on any device that the dongle is compatible with because the device is not Android head unit specific.

And its precisely because we are in a general Android head unit forum and not a specific one that I made the point - you cant make blanket statements about Android head units and their radio tuners because there are so many different types and they all behave differently.

I did not "discuss" Android tablets or phones in this forum, or even suggest that we discuss them, I just pointed out that the DAB dongle/app discussed here is meant for ANY Android device running 4.0 and up, it is NOT specifically for Android head units (which is the root of many of its problems). Having said that, as the app and dongle will work on ANY Android device from 4.0 up, if someone is using it on an Android device other than an Android head unit, this thread is the only place where they can discuss it.

---------- Post added at 01:17 PM ---------- Previous post was at 01:15 PM ----------

There are no "Joying" headunits, Joying is just a seller, your MCU will tell you what unit you have, although you dont need to know - as mentioned already the app/dongle will work on almost any Android device from 4.0 up and all of the headunits joying sell are at least 4.0
[Android Head-Units] Olav_888:
I'm not a developer, I'm only the guy with the stupid ideas, that must implemented the others ;)

I understand, that the DAB modul is not possible to receive the UKW signal, but the head unit should have a receiver for this and the DAB+ App must "only" access this receiver.

I known, really stuppid ideas from me :laugh:

If you would more stupid ideas, send a PM, then we can discuss this in german, my english is not so perfect
[Android Head-Units] typos1:
Its not that it isnt a good idea, its just that it would be very, very hard to do because the app would have to be able to open the AM/FM radio app and then tell it what station to tune to.
[Android Head-Units] Olav_888:
Thats right, only switch to the native radio app is not the solution, because

- there are no trigger available to switch back to DAB

- the DAB app don't know anything about the available FM stations

so must be the FM implemented in the DAB app, always scan the FM band for identical stations and switch to FM on failed DAB. After DAB is recovery, the app must be switch back to DAB

I know, a really stupid idea from me, not so easy to implemented, specally because this is only the hobby from you. But If you don't know, what you are making in the holidays.........:laugh:

There is easier create a third card with the station informations about title , artist, album and so, but htis is also only a nice to have feature in the wunderful app
[Android Head-Units] typos1:
The problem there is that this little DAB module does not have FM capability.

There are AM/FM/DAB radio modules available - they are used in OEM car radios, but AFAIK no Android stereo manufacturer has yet used them on an Android stereo (despite quite a few Android stereo manufacturers using other components that are used in OEM stereos).
[Android Head-Units] Olav_888:
Ok, stupid question: Why the app can't access to the (external) DAB modul and the internal FM-Modul parallel. One app, two modules for receive DAB and FM.

I'm not deep enougth in the android development, so i don't know, if there are restrictions about this
