Ps. Zoulou is it an option to change the buffer size? That way a poor reception would be less annoying

This app is still full of bugs of the current existing functionality. My goal is to minimize the bugs, not adding new functionality to it.

FYI: To change a few buggy lines in the code takes me hours of work. Adding new functionality would take me weeks and month in the way I have to modify the app.
[Android Head-Units] hans.vinkers:
Ok thanks for your quick reply. I actually have no idea how the programming works, I just have ideas [emoji4]

You lucky guy, you can use your steering wheel this the app?!? I cannot with my current unit (JY-VL130N2).

This is because the DAB+ app is not prepared for the non-MTCD system apps on these JY units. But I may have found a way to fix this in the app and may be I even find a fix for the "scrolling" issue. I agree this is very annoying.
[Android Head-Units] binar1:
You have done a great job with the app. Only problem I find is if I remove my ignition key and the head unit powers down sometimes when the head unit powers up again the app hangs on the connecting screen, I then have to close the app and restart, then all is well.
[Android Head-Units] PSRL:
Will this app work on android 6.0?
[Android Head-Units] realzoulou:
I looked into the buffer sizes when I was working on the "stuttering in background" topic. The buffer sizes are ok as they are. A poor reception is a poor reception, you cannot overcome this issue with a bigger buffer size because the DAB audio samples missing due to the poor reception are simply lost. With a bigger buffer you hear the audio drops out later than with a smaller buffer. And when switching between stations the time before you can hear the audio would be longer because of the increase time for buffering.
[Android Head-Units] realzoulou:
Yes it does so on my unit and many other users with other units running 6.0 also confirm.
[Android Head-Units] PSRL:
Thank you... will try on my dasaita unit asap
[Android Head-Units] tds4u:
Hmm, so all is made by reverse engineering? Maybe it's better to analyze the functionality of the DAB+ USB stick and build an own application?

It's like Linux began in former times: Look how it works, e.g. put USB stick on PC, and start programming step by step. If you need tester, write me :)
[Android Head-Units] MariusOX:
Does not work on my MTCC-KLD6 V.2.97

Android 5.1.1.

It only shows and spinning animation and says: connecting
[Android Head-Units] realzoulou:
This is when the DAB USB adapter is not recognized. Which adapter do you use?
[Android Head-Units] MariusOX:
This, says it's Model:Y0102. It is not using USB. Or it might be just with non standard connectors.
[Android Head-Units] rigattoni:
You are not able to install both.

Try one and if it does not work correctly try the other one.... and you have to deinstall the old one before.
[Android Head-Units] realzoulou:
Yes, I would start with the "normal" apk and if you have problems, try the "nousbdf" version.

I have put a text file into the zip, where you find more infos about what this nousbdf version is all about.

The temperature and the network throughput is a builtin feature of the Joying units. The temperature is read from CAN bus.
[Android Head-Units] ch_swat_89:
Hi realzoilou

Is it possible to add an short buffer time (5s or something) to skip these signal problems? I think my factory vw dab applicaton had this feature....

Regards

[Android Head-Units] Lynara:
Buffering a broadcast signal won't help you with that.

If you lose signal the frames are lost. A buffer will not help you with that since lost frame stay lost. Thats the nature of a broadcast, you can't request a retransmission.

DAB is a onewaystreet.

I have a seicane allwinner t3 unit i want to buy a dab receiver for US any suggestions on what i should buy?
[Android Head-Units] ffthe01:
Man you are awesome. The app is much better than the original one. i have installed nousbdf version. Anyway just one problem whenever i run the app it stucks on connecting so i have to exit then open the app again to make it work. I have changed the settings from the settings panel of the app but it stil does that. Any idea on how to fix it?
[Android Head-Units] SkyBeam2048:
I suspect the antenna has a built-in amplifier which is phantom powered (12V supplied via antenna cable).

Likely the OEM head unit provides phantom voltage and the Android head unit does not

Try to get a phantom power injector. These are small devices put between the radio input jack and the cable going off to the antenna. Powered by 12V and consuming few power you can connect them to the blue amp wire provided on most android head units.
[Android Head-Units] ch_swat_89:
That makes sense :D

I think my factory radio (VW) took the FM-Signals while there was no DAB Signal.
[Android Head-Units] realzoulou:
Have you tried the "normal" version instead of the "nousbdf" version?

Seems I cannot fix the Connecting issue for all and everyone. The USB devices detection and permisson granting behavior seems to be too different amongst the head units, although all Android devices should behave the same according to Google's documentation. Nevertheless, the Internet is full of questions of developers on how to implement it correctly.

So, if the "normal" version also shows a strange behavior regarding USB, then I am afraid I cannot help you.
[Android Head-Units] hans.vinkers:
Can anyone tell me the name of the connector on this? I think sma or smb but I want to buy an adapter to f connector so I can experiment building an antenna

[Android Head-Units] Kurt Lund:
As a follow up on an earlier post. The DAB signal was turned off and all channels transfered to DAB+ in Denmark on 1st October and since then I have not had any problems with the squeeqing or peeping noice when there was no signal. Now when the signal disappeares there is only silence. The funny thing is that before I had the squeeqing or peeping noice also on channels which were already beeing broadcast in DAB+, that has now disappered too. So the noise must be related to the DAB signal itself and not the actual transmission.

Regards
[Android Head-Units] syk02jcb@hotmail.com:
I can confirm same behavior on my adapter in Norway (also only dab+), no “squeeqing” sound in my case.

DAB+ app

Hi zoulou, Thanks very much for the great app, I've been using it for a few months now and lovin it. I'm in the UK and I'm using it with a DAB+ USB Dongle I bought from Amazon for £32 (sorry can't yet post links as I'm a new member)

which is connected to my modded Jaguar touch screen head unit (thanks to Ben Willcox from the Jaguar UK forum)

I'm using a Kinetic MagnetwiG DMA-1004, bought from dabonwheels for £19.99

(sorry can't yet post links as I'm a new member)

I get good reception from the only station I'm actually interested in PLANET ROCK (I'm in the North East of England and find approx 70 stations when carrying out a scan, some strong & some weak)

I have a few request for your next version of the app if possible please

1) Could the app be configured to start with the Full Screen page where the settings icon is (rather than tapping the DAB logo after launch)but also include the signal strength indicator.

2) Could you add the facility in the setting menu to change the on screen text size for the scrolling data (I'm old and wear reading glasses but can't drive with them on)

3) Could the increase the resolution / DPI of the "world DAB digital audio broadcasting" logo as it looks a little blocky when on full screen mode

4) I think it may have already been asked for but I'm not sure. Can album artwork and additional data be displayed in the UK.

If you could manage ANY of the above requests it would be greatly appreciated. Thanks again for the GREAT app.

Why don`t you buy a DAB+ / FM roofantenna from Ali ( 22 euro), then you know for sure that it works. Instead of experimenting. It works for me in The Netherlands.

I need a double fakra connector for my headunit and I cannot find that one. Otherwise I would have ordered it already

Verstuurd vanaf mijn Z2 Pro met Tapatalk
[Android Head-Units] Lynara:
Double fakra is only useful / available if you've got multiple antennas.

You won't find a single antenna with double fakra, since it simply doesn't make any sense.

The double fakra is for antenna diversity (switching between two antennas and using the one with better reception), if you just connect one fakra plug the diversity will only use this one antenna (since it will always have the best reception compared to the unconnected input) and everything should be fine. (did the same with my headunit)
[Android Head-Units] syk02jcb@hotmail.com:
Anyone of you guys that have mounted a universal roof “Ali-antenna” on a Ford? I have a Mondeo mk4, seems that the hole in the roof needs to be bigger with the universal antenna? I’m pleased with my glassantenna, but I’m looking for the perfect solution :)
[Android Head-Units] davetaylor85:
I have a mondeo mk4 and i haven't mount a new roof antenna. I used this splitter <<Antennentechnik-Bad-Blankenburg-Frequenzweiche-Splitter-Schwarz>> on amazon. Works great and pushes the signal strength of FM a bit, too.
[Android Head-Units] hans.vinkers:
The double connection is standard available in my car, the original antenna is for am fm and GPS. The GPS had a separate connection. Did you find the superbat antenna with fakra ?

My car is seat Leon 2008 and the headunit erisin 8015 (Volkswagen)

[Android Head-Units] syk02jcb@hotmail.com:
Inside the fakra it’s really just a smb plug, the plastic housing around it is just for avoiding wrong connections...

---------- Post added at 08:13 PM ---------- Previous post was at 08:08 PM ----------

My Mondeo mk4 has a combined fm/dab antenne already, but I can’t get a good signal to the dab adapter. My original Sony head unit gave 12 volt out to the dab part, I have tried with a phantom adapter without luck.

But of course I can try your suggestion and just go with the fm part of it. I’ll check it out, thank you!
[Android Head-Units] Helgeo:
I still get the high pitch sound when loosing reception on either one of the only two channels in Norway using 128 kbps: P4 and Radio Norge. All other channels are fine.
[Android Head-Units] syk02jcb@hotmail.com:
Ah, ok. I do not often listen to those channels, but I will check it out soon and give a feedback...
[Android Head-Units] davetaylor85:
Yes, i had the same. The issue was solved by the solution i gave you. The antenna of the MK4 has the perfect length for DAB. The biggest issue is, that the DAB-Box from Pumkin always was on and gave a small induction on the antenna, which was shuttering the signal on FM. I tried several things:

- Just phantom adapters (active and passiv)-> no signal boost

- 2 different FM/DAB-Antennas from Amazon -> very good signal on FM and DAB, but there was no antenna of the right angle for the Mondeo roof, which would have caused a disaster at the car wash.

The Spiltter i named you, is active and gives this 12Volt output (i soldered it to the 12V cable at the cigarette lighter) and seperates the induction from the dab-box and the antenna, so the signal for both FM and DAB would be the best. For me, it was at the end the same signal strength as with the new rooftop antenna, without loosing the original look and angle.

And besides it's even the cheaper solution;)
[Android Head-Units] syk02jcb@hotmail.com:
Ok, great! Thank you!

I have a 10.4" Android 4.4.2 unit for Porsche Cayenne. I first installed your version as it worked flawless on my Samsung S6, but on this Cayenne unit it stutters extremely. The original app doesn't except when running in the background. What can be wrong?
[Android Head-Units] realzoulou:
You are the first that reports such behavior.

I cannot explain that.

Do you see that there is a notification of the DAB+ app when you swipe down the status bar? If not this might be a symptom.
[Android Head-Units] syk02jcb@hotmail.com:
Confirms the high pitch sound on the two 128 kbits channels for me as well. All other bitrates ok
[Android Head-Units] ynorynor:
No, I don't see a notification of the DAB+ app. Actually, I don't see any notifications on the status bar for any app. I do see the notification when I run the app on my Samsung S6, but not on the Cayenne unit running 4.4.2.

I wonder if the hardware of the Android unit is running too slow for the DAB+ app? It has a Quad Core 1.6 GHz A31 series, 1 GB RAM
[Android Head-Units] realzoulou:
Your hardware is powerful enough. No worries.

Not every app automatically comes with a notification bar entry. It is usally not needed. But if an app wants to consume some significant amount of CPU in the background, like the DAB+ does, then Android requires the app to show a notification to the user that this app runs in background and may drain the phone battery.

Can you double check that in the DAB+ app info (Android Settings -> Apps), the check box for "Show notifications" is enabled?
[Android Head-Units] ynorynor:
Thanks! Yes it is enabled but DAB+ still doesn't show in the notification bar.
[Android Head-Units] rigattoni:

[Android Head-Units] Bose321:
Finally installed the ****ty antenna I got with my receiver, and it's pretty bad as expected. However, it does work great for a few stations in a small area.

Anyway, any way I can display the currently playing station? I do have the notification, but that only displays the static and useless text about making DAB great again. Also when I press media buttons (pause/stop/next/previous) nothing happens.

edit: Running an older version of the app it seems. Gotta try a new version tonight!
[Android Head-Units] MrAndersen83:
Hi

Most glass mounted antennas come with a piece of copper foil that you are suppose to stick to the window frame, however the frame is usually painted and the copper foil has the adhecive between as well, but if you solder some wire to the foil instead and connect it to the nearest grounding point you could get an inorovement in signal.

I've got an OK signal inside my apartment block garage.
[Android Head-Units] Bose321:
Interesting, I didn't pay attention while fitting the antenna, and I didn't put the copper bit on the frame. I thought it wouldn't matter, but now you're making me doubt...

[MENTION=7838245]realzoulou[/MENTION] I have installed the latest app, and it seems to work a lot better now! However I have one question, can we get an option to disable the notification at all? I could disable the rights to the app, but an option would be cleaner. I don't need to see the current channel name in there because I want to integrate it in my media app: https://xdaforums.com/android-auto/...-development/app-fm-radio-controller-t3625038

I've checked the broadcasts and it seems easy enough to implement this as well. I currently support the default music and radio app, and your adding DAB app would be a great extra feature.
[Android Head-Units] MrAndersen83:
Does anyone have their steering wheels keys working with this app or do I need to configure this someware on the head unit?

[Android Head-Units] realzoulou:
No, I can't remove the notification because otherwise audio stuttering when the app is in background would be back again.
[Android Head-Units] Bose321:
That's interesting. Isn't the app using a proper background service?

Would the stuttering be there if I would disable it in the Android settings?

---------- Post added at 10:58 ---------- Previous post was at 10:05 ----------

Is there also an option to stop/pause the playback?

Also, is there a way to check if the DAB player stopped playing? The radio app has a power intent that's broadcasted with a boolean with power on or off, and the music app has a playback broadcast (0 = stopped, 1 = playing, 2 = paused). Would be great so that I can see when it's no longer playing DAB. Or do you maybe use "com.android.music.playstatechanged" as well? You have a playing boolean, but that's always true according to your txt file.
[Android Head-Units] realzoulou:
It is using a background service. But when a background service wants to use a significant amount of resources from an Android system, it has to fulfill what Google documented here in “Running a service in the foreground” https://developer.android.com/guide/components/services.html#Foreground

At a glance: The background service "DABService" in its onStartCommand() creates a Notification and then calls startForeground() with this Notification and then returns START_STICKY.

Never tried myself. If you tried it, please let us know.

No, there is no option to stop/pause. Honestly I don't see why this would be beneficial. Would you expect play/pause from a FM/AM audio app? DAB is a broadcast service just like FM/AM. It makes no sense for me to pause or stop it. If you want to stop listening to DAB, then exit the App.
[Android Head-Units] Bose321:
I obviously don't want to pause it, but I mean you have a 'power' switch on the FM app which enables and disables it. And when it does that (whether you do it manually, or another app is playing music which makes the radio stop) it sends a broadcast in which power is true or false. That's what I use to know when the radio is playing or not. It would be nice to have that as well in the DAB app so I can see whether it's playing or not.
[Android Head-Units] rigattoni:
Just a second...

If DAB is in Forground and I switch to my FM radio, DAB is stopped automatically as well as if I use any Media player.

DAB looses the Audio focus and that leads to switch to the new source.

So what is your point now? Seems that we didn´t get you right...

Do you want to keep DAB active in background, without ending but in pause?
[Android Head-Units] Bose321:
No, I just want the DAB player to send a broadcast notification that it has stopped. For my app I need to know if the DAB player is still playing, or that something else is now playing.
[Android Head-Units] realzoulou:
I can change the "playing" to false when the DAB app finishes. I guess this is what you need, right?
[Android Head-Units] Bose321:
Yep! That would be great.

I have the same problem on my xtrons td101as device - sw knobs are working with every app but not with the dab+ app. When trying different mcu / android version files there was one combination where the buttons worked but unfortunately I do not remeber the exact versions. Now using newest GS mcu / android version sw buttons do not work with DAB+ app in background :/
[Android Head-Units] syk02jcb@hotmail.com:
In my case when it stopped working in background, the reason was Spotify. Spotify seems to override other apps with my swc. Uninstalling Spotify didn’t help, a factory reset without installing Spotify make swc work with dab in background again...
[Android Head-Units] OnkelDeffe:
Thanks for this tip, but I don't use Spotify at all - only the standard apps coming with the radio.
[Android Head-Units] syk02jcb@hotmail.com:
Ok. I guess you don’t have changed anything, but it could be an idea to check that the “steering key assign” (ish) under other in factory settings is enabled, and/or check your canbus settings as well...
[Android Head-Units] OnkelDeffe:
As I wrote the key assigment works in every other app but not with dab. I assigned my "+" and "-" steering wheel keys in the sw app to "next track" and "previous track" function. When starting f.e. the media player reading from usb and then the navigation app I can switch tracks with my steering wheel knobs when navi app is in foreground. Same works with fm radio app in background, with playing from dvd in background aso. So I think that technically everything works fine - the only app that will not react is the dab app. As I wrote: during testing differrent android / mcu versions there was one combination where the dab app did react as expected but I don't know, which andoird / mcu version this was. Maybe that the neccessary android message is not send to the dab app - perhaps a log from the dab app for testing could help here
