No video signal. 4

Hello All,

Great app. I wish I could use it (or use Appradio for that matter). I've searched the forum and Google for +20 hours now.

I cannot see the white calibration dots. No video is being transmitted. The screen remains black/grey. I can touch where they "would be" on the AR3 unit and successfully progress to the next dot (i.e. Bluetooth is working). I still get no video signal.

Yes, the parking brake connection is being cycled.

I'm using an official Pioneer CD-AH200 MHL kit. The MHL cable has been proven when connected to a TV via a Pioneer SC-65 receiver, with no video issues.

I have tried uninstalling ARU and installing Appradio. No change.

I have tried connecting the MHL adapter usb up to an alternate power source. No change.

I have tried a bunch of other stuff. No change.

HTC One (M7); rooted; stock 4.4.2. Do I require any special fix???

I have stumbled across similar posts; no solution.

Any help would be appreciated.

Hi,

As fare as I can read, your problem is the HDMI connection between phone and appradio. Even with no Bluetooth connection, your appradio will change from black/grey. So check HDMI cable from appradio to MHLI adaptor, and again be sure to connect your phone properly to MHL adaptor. (I assume that you have power cable to your MHL adaptor)

PS!! I have had problems with the HDMI cable from the Pioneer kit, so first try and change HDMI cable

[Android General] lankinbra:
Thanks for the reply. I have no issue with Bluetooth. It connects every time. With the Pioneer CD-AH200, the MHL adapter is powered by the HU usb output (though I did try an alternate supply - in desperation). It's power supply is not an issue. I did spend four hours removing and re-installing the HDMI/MHL adapter to test the HDMI signal (PITA). There were no issues. The exact HDMI/MHL that feeds the HU had no issues supplying video to my TV. I suspect I will need to source/try an unrooted phone with only Appradio installed to troubleshoot whether it is a phone issue or not.
[Android General] basmand:
HI

I still think that it has nothing to do if you are root or not!, the only thing this icon on the screen shows is: are there HDMI input to the unit. I normally runs an HDMI stick and not a phone, and I have changed 2 HDMI cables during the time I have worked with appradio

[Android General] Area51©:
Actually A2DP is not necessary for AppRadio mode. In AppRadio mode audio is sent to the radio via HDMI and communication for touch/keys/GPS is done using SPP.

With Samsung from android 4.3 and up only rooting is not enough. It's also required that Knox is switched off and SELinux is in permissive mode. This has been discussed in this thread multiple times. So please search for it. One way to fix it is indeed to install another kernel that is in permissive mode by default.
[Android General] Area51©:
It could be the HDMI cable but also an HU internal error. One way to check is to connect another HDMI source (laptop, dvd player or the like), the Apps icon will light up, hit it and then press ignore for the BT connection. Basically it should then show the HDMI source on screen. If that doesn't happen it's either the cable or an internal HU hardware error. If you checked with a few cables, only HU error remains.
[Android General] 400ixl:
[MENTION=5847205]lankinbra[/MENTION] - Does the Official AppRadio application work OK? Uninstall and unpair, then go through the process with the OEM application first. If that works then your cables / HU are fine and we are into finding an issue with your phone. If it doesn't, then its cabling / HU.
[Android General] lpasq:
[MENTION=324146]400ixl[/MENTION] you still on your N4? I recall you helped me way back when getting into the AR2 with N4 and ARL. My N5 and AR3 with ARU is near flawless and hope people who really want to experience hacks and bleeding edge solutions note that Nexus class devices should be their first option.

It is nice that you take time to help out users on this ARU thread and still help nurse along the ARL forum. Not meaning to hijack thread but mostly wanted to hear what device you have and how your HU mirroring is going.

Thanks for helping noobs and lurkers, and not feeding trolls ;)
[Android General] bk73w:
For Samsung devices it's something else. Not exactly sure how that goes I believe they mentioned it a few posts back.
[Android General] 400ixl:
Yep, still on the N4 and AppRadio 2, haven't had the need to change it, tweaking it here and there keeps it performing. Will look at the next Nexus phone probably, or whatever is available towards the end of the year.

Thanks for the comment, more than happy to help where I can and share experiences. The more people doing this, the more seriously the manufacturers will take advanced functionality.

One thing I have found with the slimport adapters (Analogix ones) is they are great for a while and can then start to suffer with interference. Have switched to a different one which has a much longer fly lead, but no ability to side charge (this is what is causing the interference on the Analogix). Power is now supplied by a QI wireless charger and keeps up with navgation etc power drains. Might even have a play with Miracast soon and make it truly wireless in the car.

Seen you helping plenty of people too, so good on you for passing on your knowledge as well. Glad to hear the N5 and AR3 are working for you as well. Its a good setup when you get it right.
[Android General] RubenRybnik:
Finally got around to getting this all setup. I'm using an AT&T LG G2( Stock Rooted ) with slimport and the android connection kit from Pioneer.

I have a Tasker profile setup to force rotation lock, disable wifi, set screen brightness and media volume. When everything works its absolutely fantastic. However I'm having a problem that others seem to have run into but the solutions I've found don't seem to work.

AppRadio Unchained and Mirroring aside my bluetooth works great. When I start the jeep it auto connects, both phone and media, and I can play as you usually would. However when I physically connect to the App Radio I get the "Establishing Connection" message and 8 times out of 10 it will fail, leaving me with mirroring but no touch controls.

I've tried disabling auto connect, I do have it set to "Other", I've tried first bluetooth connecting then Slimport connection and vice versa. Nothing seems to be reliable. I just sat in the Jeep for 15 minutes trying to get the thing to "Establish" the connection correctly with no luck.

Does anyone else have a solution? Maybe something with Tasker? I'm at a total loss here, don't even understand why it needs bluetooth since audio is over the HDMI... It would be nice if this "check" could be disabled but I'm sure its there for a reason, or its hard wired into the head unit.

EDIT:

Just wanted to add, I have the slimport adapter, on recommendation on this thread, from http://www.amazon.com/dp/B00DWGB6CU/ref=pe_385040_30332190_TE_M3T1_ST1_dp_1

And the HDMI cable( also on recommendation ) from http://www.amazon.com/dp/B003L14WUE/ref=pe_385040_30332190_TE_M3T1_ST1_dp_1

I did by the GPS Injector just to support the project but currently this is an unusable setup for me, can't be fiddling with the phone for 15 min every time I want to head out lol. Hopefully someones got something for me that I didn't find searching. Thanks all!
[Android General] HueMann:
Delete and re-establish a new bluetooth connection. This time tho, do not click the "never to show the contact and history requests again" . Sure, every time you hop in the car you'll have to allow the HU access but the problem is solved.
[Android General] lankinbra:
I was not aware that could be done. I will test with my laptop.

---------- Post added at 01:35 PM ---------- Previous post was at 01:30 PM ----------

No. AppRadio produces the same unfortunate results. No video. I am going to do some more cable investigating.
[Android General] 400ixl:
OK, first up, is the output on the HU set to other rather than iPhone?

Secondly, does the phone display to a TV using the same cables?
[Android General] RubenRybnik:
Actually I may have found out what the issue is( may ). I did what you stated above but I usually click "Allow" and "Do not show again". This time I clicked the "Deny" but still checked "Do not show again". I just went 8 for 8, both bluetooth first then HU and starting the car while plugged in. Every time worked. Either testing was a fluke or "Denying" it fixed the issue, at least for Stock ROM on LG G2, no idea about others.

I'm thinking of leaving my nexus 7 in the glove box so it will always connect then I can just pick up the phone normally ( not sure if the HU will play nice with Nexus 7 connected as media and phone as 'phone', I'll have to play with that later ). The bigger question is automating a hot spot on the phone( I guess I will need bluetooth for the context for that ), then auto connect with the Nexus 7. Not really asking a question I guess, but if anyone has some tips feel free to chime in ;)
[Android General] codee:
I will be checking this out after work hopefully, and if that is the issue/resolution I really think that should be in the FAQ/common issues area? Samsung is one of the most common phone manufacturers and with the s5 just coming out and the s4 getting upgraded to kitkat a lot of other people are likely to have the same issue. Would have saved me a LOT of time as the FAQ, common issues, and links to the ARL forum are the first things I looked at as the thread directed... Follow proper forum etiquette by reading the FAQ and I got nowhere lol
[Android General] bk73w:
You could also use the tools of simple common sense, delegation, and the search bar.
[Android General] codee:
Oh guess what? I did search but thanks for the helpful and constructive tip. I have 66 posts since 2010 so I wouldn't say I exactly ask a ton of questions or just signed up to post a question and didn't read anything.

Thanks though!
[Android General] HueMann:
Well after many test and roms, Trials and errors, I've come to the conclusion that the GT-i9305 will not work with ARU. The phone works fine with the official appradio software but not with unchained. The problem I have even after all the tweaks and tricks is that after the initial I stall and The display adjustment, touch stops! I can see my display but touch does not work.

Official Samsung fw rooted with autoroot.

My s4+ works like a charm but not the s3 4G! Why??

Any help here?
[Android General] bk73w:
No problem pal, I'm here to help. Please don't hesitate to hit the thanks button if I've helped you in any way in your endeavors.

---------- Post added at 07:37 PM ---------- Previous post was at 07:34 PM ----------

S3 has been proven to work, don't give up yet!

Did you try " With Samsung from android 4.3 and up only rooting is not enough. It's also required that Knox is switched off and SELinux is in permissive mode. This has been discussed in this thread multiple times. So please search for it. One way to fix it is indeed to install another kernel that is in permissive mode by default."-Area51
[Android General] HueMann:
Yeah, I read that as well. I've put the official kernel in permissive mode but still not working. I also tried custom roms and they didn't work either.

Very strange that the official app works but not ARU....
[Android General] 400ixl:
Not strange at all, the official app doesn't need permissive rights for the touch functionality. That is why it works without root.

Some people have solved it by running a custom kernel. Problem is that it is different for different Samsung phones in different regions on different operators. Searching and trial and error is currently the only way. Someone should build a list of devices with solutions.
[Android General] HueMann:
Hear hear! ;) been pulling my hair out the whole last week. CM11 has no mhl support which sucks the big one! Official Sammy works the best for my wife because she doesn't want alot of change. Got that, did that,, and still... Hmm

I'll try some other kernels but I still think the problem should be solved in ARU.

EDIT : I mean, the idiots who installed the stereo can't even get the back camera working without my input! And they are supposed to be pros at this stuff. When I showed the installer how ARU worked with my s4+ I think he **** himself! Lol
[Android General] bk73w:
Did you try the Pandora trick?
[Android General] HueMann:
Please! Do tell. All ears here.. :)
[Android General] 400ixl:
Why should the developer of this app try to resolve a security layer the provider of the phone you bought has put in place? Thats like saying the app should be able to root every phone that may be compatible with the app.

Not reasonable and not going to happen. Blame the manufacturer of your phone, not the developer. In the same way as it is down to you to find the right way to root your phone, it is also down to you to unlock the SELinux enforcement. Samsung are the only manufacturer to go down this route.

It is not even remotely reasonable to expect the developer to sort this problem for you.

---------- Post added at 09:31 PM ---------- Previous post was at 09:29 PM ----------

As mentioned lots of times in this thread (search would have found it) some people have found installing the Pandora app sorts some connectivity issues. Mainly US based people.

Doesn't need an account in Pandora, just for the app to be present on the phone.
[Android General] HueMann:
OMG!!! HAVE I JUST BEEN FLAMED BECAUSE THE OFFICIAL APP WORKS BUT NOT ARU! WHICH I WOULD AND WILL CHOOSE TO CONTINUE TO USE EVEN I CAN NOT GET MY WIFES PHONE WORKING WITH IT!!?

I AM HERE ASKING FOR HELP AND I KNOW THERE ARE A FEW PEOPLE HERE WILLING TO HELP OTHERS! INCLUDING ME.

"Pandora trick" tells me a lot. I forgot that meant I should shut the **** and solve my own problems because there are so many people here who are so tired of helping those who have just now! run into the problems that may have been solved so many posts ago!
[Android General] AgentJz:
Hi...I looked but did not see which exact cm11 rom I can use on my Verizon S3.

Any help is appreciated.
[Android General] leobg:
Official app is not trying to inject touches on system level (hence no security preventing it from doing it).
[Android General] 400ixl:
So you are now saying I have not been trying to help you? You were the one saying that the app developer should sort your phone issues that are not caused by his app which is completely disrespectful. You then have a go at the people who ARE giving you help and have helped dozens of people on here get it working.

Get a life and a perspective or people will very quickly stop trying to help you. Shouting at people and being a keyboard warrior is a very quick way to stop people offering advice.

If you try the things that have been suggested and report back, I'll try to help you further. Continue to make unreasonable demands of the dev and throw abuse at me then you are on your own. Your choice.
[Android General] HueMann:
Please, please please please ask for information about the "Pandora trick"? Please!

I did a search and got 10 pages worth nothing! " appradio " and " Pandora " triggers only.

What is the Pandora trick even though I never use, or have any need to use Pandora?

Any and all of you who are willing to help me, please excuse my sarcasm. It's just that sometimes the kids in these forums today have forgotten what community means.
[Android General] ikerg:
I don't think you can use cm11 on s3 because of lack of HDMI drivers.

You should move to samsung's stock or other stock based custom Rom. You can switch to a kernel that allows selinux to be in permissive mode.

I don't have appradio yet, i am planning to buy it (AR3) but i read all the posts. If i am wring, please smbdy correct me.

Is i just commented i do not have my appradio 3 yet.

My intention is to connect it permanently to a android tv stick (i have a imito mx1 - dual core 1gb Ram with bt)

I have a mazda cx-5 and i can use the armrest usb connector to plug it to the usb connection on the tv stick

Additionally i plan to buy a hdmi switch in order to sometimes change the input video and touch from imito to my phone (sgs3 international version i9300)

When android tv is switched on i could perform calls by bluetooth, so i supposed there are two independent bt connections on the AR3 to do that. Is that correct?

If so, i could be fine to connect an Ipod for additional music source. Is there any android app that could emulate the "made for ipod" feature of common headunits and use the android tv usb input to control an ipod and see the playlists/artists/songs.?

Many thanks in advance

[Android General] 400ixl:
Cyanogenmod 11 does support HDMI, but can be flaky on some phones and not work on others. But you are correct that some have found that changing the kernel on the OEM ROM works.

If you haven't taken one of the later OEM updates, you may not have Knox anyway. Best to avoid OTA updates if you haven't and go for custom.
[Android General] ikerg:
Now samsung is rolling out the kit kat version for the s3. It started with sprint version, but it should be available for the rest of operators and for free operator in a short term.

Additionally is is recommended to wait for the cookers to adapt the official release to an "un-knox-ed" version of the official Rom.

Thank you for pointing that out for me. As I posted before, I have been pulling my hair out trying to fix my wifes phone. My phone works like a charm. If I have to install Pandora on her phone to get ARU to work as it should without any help or input to or from the dev then I guess that will be the next thing I do. But really, shouldn't this be considered an issue which deserves a little more looking into?

Pandora? I don't need no Pandora! .. Just a joke! Just kidding! ;)

GS4 i337 (4.4.2 stock, rooted) connection issue RESOLVED

Ok, well this is a revelation! Seriously... based on my previous experiences, the last 5 months running with 4.3 (stock, rooted)... I always needed to get an A2DP connection for the touch part to work. No A2DP, no touch. 100% of the time.

But you're right... not needed. With that new understanding, I was able to search for a solution and I found it. I used Tasker to create a script that disabled Knox and set SELinux to Permissive, and Hey! Presto.

The only other thing I should add here for other folks having the same issue is that you need to do this every time oyu reboot your phone (which is why I used Tasker) and you have to start ARU after the script runs and the permissions are set correctly. This actually takes a few seconds. So you either have to shut down and restart ARU manually, or incorporate an ARU kill and restart into a Tasker profile. That's my next step... not that I should need to reboot that much any more.

Thanks for the point in the right direction.

JD

PS, just as an FYI... it's not that I'm averse to using search functions. In fact I'm rather good at it. It's just that without your hint, I would never have known what to search for.

No solutions yet. HU is set to "other'. My laptop connected fine through the Pioneer HDMI cable that came with the Pioneer MHL kit. Actually watched Netflix on the HU with good picture and sound.

Phone connects to Panasonic TV using the supplied MHL adapter and cables. Watched Youtube. Video and sound both good.

Strange part: Phone has difficulty connecting to Pioneer home receiver. Video cuts in and out and the audio is not transmitted (stays on the phone).

After trying the laptop on the HU, there was a brief moment when the phone screen made it to the HU. But the image cut in and out and had no audio signal (as with the Pioneer home receiver). I was not running AR or ARU and had the MHL adapters power connected to a different source. I thought it might of been a power drain/supply issue; but, I've not been able to duplicate these results. ?????

4000 NEX phone screen too big

Hey all newbie here,

So I have a 4000nex and installed the OEM Appradio on my Galaxy Nexus using the Pioneer kit. Everything works, but when I go to calibrate the white dots are sometimes not completely on the screen of the HU. So when I touch all the dots and app mode starts I can't see all of my screen on the HU, many things are off screen.

So then I uninstalled OEM and installed ARU, gave it superuser, and I still have the issue....Is there anyway to fix this? I'm using cyanogenMod 10.1.3 toro.

Thanks
[Android General] codee:
I tried using the recommended program to set SELinux to permissive but I couldn't get it to stick on my phone even between reboots so I installed a different kernel with SELinux set to permissive from the get-go and knox is removed and I apparently created a different headache for myself. After installing the AEL Kernel I can't connect to my netgear Push2TV wireless display. Before it would connect 10 out of 10 times and now it connects 0 out of 10 times. The Pioneer MHL kit doesn't work with my phone without an extra adapter either so I can't try that currently.

I am downloading a different ROM and wiping the phone so hopefully something just got tripped up and I will be able to connect wirelessly again after I flash and set it up again...

GS3 CM11

CM11 and HDMI work pretty well on my Sprint GS3. My main problem is that Netflix causes my phone to reboot just about every time I try to use it, or it gives me a network error. Usually have to wipe Netflix data and try again.

On another note, I moved the GPS injector to system, but it seems I still have to open the injector and toggle it off and then on again to work. I just noticed that CM11 has selinux enforced with my default kernel. Curious, as ARU seems to works fine. I guess I'm still a little confused. What exactly does selinux prevent again concerning ARU?

BTW, thanks to Area51 for your work and to the others in this forum. I've been lurking here quietly for a long time.
[Android General] codee:
From what I've been told, SELinux enforced (along with Knox which I removed) is what is preventing Samsung Galaxy s5s and s4s above 4.2 (I think its 4.2) from allowing the deck to control the phone via touchscreen.

I installed a new kernel based off of that thinking and then after the fact I found out that apparently you can only do screen mirroring (I am trying to use the netgear push2tv adapter) on the stock kernel/rom. For me, this means I either need to use the phone to control everything over wireless or else switch to using a MHL cable instead and using a custom kernel and rom.

appradio 3 responsiveness

is the appradio 3 that much more responsive than the x8500bhs?

or should I say how much more responsive?
