[Q] Using Nexus 4 with External Display via...

Hello all, maybe you can share some suggestions to a challenging situation I'm facing:
I want to use my Nexus 4 with an external display, a Bluetooth keyboard and a Bluetooth mouse so I can work on documents on Google Drive. However, I do not have access to a good up-to-date display in the location I want to achieve this set up.
Currently, I have an older display that only has an older VGA input. I've seen some negative reviews for a slimport-to-vga device available on Amazon, so I'm on the ropes about ordering one.
Alternatively, I may be able to get a monitor with a HDMI imput. Would a slimport connection on that be recommended? Or, should I get creative and try to connect to a Chromecast-to-HDMI, if such a thing is even available.
Also, I'd like to find a reliable keyboard and mouse for this set up, or would any Bluetooth devices do the trick?
Last, are there any limitations to how many devices can run to the Nexus 4 simultaniously? Ideally, I'd be using a T-mobile 4G data connection with a wireless mouse and keyboard while outputting via the slimport.
Thanks for any thoughts you might like to share.

Via USB you can connect only one device. Display and 4G Stick is not possible.

DVB-T

Any chance to use an USB DVB-T DONGLE with NEXUS PLAYER?

Maybe. You want "TV" on your Set top box ?
Software is the tricky part. Does this work ? : http://www.geniatech.com/pa/pt115m.asp
I recall a decent thread here on XDA somewhere but can't find it right now and seem to recall the app wasn't going anywhere too fast.
And there's at least one 3 star app on Play, but doesn't work for many people.
I'll be happy just to get FM radio, with SDR Touch or whatever...

thanks, can be a thing like that but I want to use any usb dongle that I want and not a single choose like that.
For example I'v build for my daily use, a mini barebone with a small debian distro with VDR, in this way I can play divx and dvb-t as I want but, if my dongle usb dvb-t for any reason broke........I can buy the first dongle usb that I found on any market online, compile kernel module for that dongle and put in usb port it, it's so simple.......
I love nexus player, 99$ about, remote control, android marke, playing game, youtube, and more infinite possibility, but at TV DVB side I want be free to use any usb dongle DVB for desktop pc as I made today
There's any chance to get, nexus player kernel, enable DVB module for dongle, put inside usb port of nexus player, and watch tv?
At software side, is need an app or Android TV S.O. is capable to manage DVB correctly?
Thanks in advance!

Do you have any other Android devices? If you're already comfortable recompiling a kernel to support your hardware, I'd suggest trying that on a different Android device first. Then you would know if the Android framework could handle such a device.
EDIT: Here's a link to the Android TV developer site about supporting live TV in Android TV. It appears it's designed around that being possible, so if you can add your tuner hardware support to the kernel I don't see why it wouldn't be possible to make it work within Android.

ok tnx

Car Install - Mitsi EVO 9

Hi Guys,
Recently put the finishing touches to my Nexus 7 install so thought i'd share some pics.
Im running 5.0.2 lollipop and Timur Kernel, with the following attached;

Audio Volume is controlled with this - http://www.amazon.co.uk/gp/product/B00RM75NL0?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
Power supply is from a 2amp (5v) cigarette usb socket, which is wired up behind the dash and not using the original cigarette socket in centre console.
I installed the amp under the passenger seat and run all the cabling under the carpet and out, where needed, behind the facia panel, the dac is also situated there and i ran the usb hub into the glovebox. You literally cannot see any wiring bar in the glovebox as i wanted to maintain a stock look throughout the car as best i could, everything is also revertable back to stock if the need ever arises, the only thing i had to do was screw the amp into the carpet under the seat, but the small holes left would never be seen anyway.
The facia panel was designed and made by a lad named reece who runs http://www.rtafabrication.com/ - top bloke and did an amazing job and the finish and quality of the panel is top notch. I went for a wired dash panel but he can also do wireless panels too!!! - if your thinking of a car install contact him to see if he can design a facia panel for your vehicle.
android apps i use
poweramp,
sat nav is navfree
video is archos Kodi.
As you can see, also for fun have a megadrive emulator with ps4 pad to play games lol. Also can use either torque pro or OBDlink II for my OBD Link LX bluetooth OBD port reader. (http://www.amazon.co.uk/gp/product/B00H9S71LW?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00)
Had an alpine before which was a great piece of kit, but nothing compared to this.

Got any videos of it all in action?

Awesome job

I'm planning on doing the same, but not spending as much as you lol. I see so many integrations with android to car, but no discussion.
Great integration btw!

You installed your wheel on the wrong side! A common mistake on these installations

Great Job!
Dis the same on my S2000

Haha, I see why you did there[emoji23]

I came running once I saw Evo in the title, That's my favorite car of all time, and to do that with a nexus 7 gets me hyped to do the same once I save up for one

Now just get digital car app ....gotta sign up on g+ for it ...

Nicely done! I'm running a similiar build in my car, using glitch kernel not Timur's. How are you finding Timur's? Reliable? I find glitch occasionally needs rebooting as it fails to mount my USB DAC.

In terms of Timur ROM reliability, its great and had no issues worth mentioning so far

Im thinking of buying his rom when i can afford it. But i have it in my car without a usb otg. So the rom is not fully functional to what it can do once i get around to get a usb otg.

What the advantages of having Timurs Kernel? I have ElementalX.... Thanks

I have never used Elemental X but my understanding of using Timur over any other Kernel was that it uses his own Powerevent Manager app which can do things like wake up when power is applied and deep sleep when power is removed, something i believe Tasker can do. Also not sure if Elexmental X allows simultanious USB hosting and charging + Fast Charging. Supports certain Rear Camera's. Automount of upto 4 FAT32 drives, custom boot animation and shutdown video's, block wakeup alarms. People using other kernel may tell me otherwise but this is what i came up with when researching which to go for.

Just a question to be sure I understood everything.
Without USB Hub, you plug the OTG cable to the tablet and USB DAC to the USB port. Then the USB DAC is connected to the amp using RCA correct?
Currently my setup is not using a DAC (rca to jack directly connected to the amp) and I have interferences because of that so I'm thinking about using a DAC. Is it natively managed by Android?
Thanks,

Yep that is pretty much it, OTG cable then USB DAC straight into USB port, and connect it to your amp / stereo via Red & White RCA jacks, or as i did - - - - - Nexus 7 - OTG cable - USB Hub (4 port) - USB DAC - AMP
I believe Lollipop handles USB audio natively, anything before needs a kernel to implement it - again if anyone knows different then please let me know

Is audio taken from usb? I didn't think any Android can send audio from the usb? Or is that why I need the OTG-cable?

That looks amazing, stock even, imagine having Andoid auto on there.
Any pics of the evo?

modification Nexus 7: HDMI instead LCD

Hallo,
i have a old Nexus 7 1nd 2012 and the LCD is broken.
I would like solder a HDMI-Output instand the LCD.
1. Is that generally possible?
2. Where can I find the LCD interface description?
3. Do I need or where can i find a kind of "gateway" / Converter?
Thank you very much

IIRC the n7 2012 has slimPort, no soldering or modding required.

No, only 2013 model has slimport. The 2012 has only simple USB 2 port.

If it doesn't support slimPort or MHL, then I doubt that you can connect an hdmi cable to the LCD port, as the LCD uses a very specialized input and no adapter will make it work with hdmi. Have you checked out software screen mirroring solutions thru USB or network?

Yes, I tried Mirror beta from Clockwork Mod. Sometimes it was working but I had some lags. Now the app is called Screen Recording and Mirror but I don't use it anymore. May be the thread opener want's to try it. But with broken screen it will requiere keyboard or mouse on the N7 and a second device as receiver to use it.

I was thinking about solutions working over adb or some other usb interface, all the network ones I've tried are like mirror and have huge lag.

@all Thx
1. The Nexus 7 1nd 2012 has a 2.0 OTG-USB
2. Screen mirroring over USB should only work with a Hardware USB-Port: MHL or Slimport --> Maybe it exist a USB 2.0 Converter to HDMI/Nexus 7 without Charging-Function, but this is not known for me.
3. Network mirroring is lagging.
4. adb = im asking google. I will report ...
--> What im searching for, in a kind of this:
http://www.ebay.com/itm/M-NT68676-2...ontroller-Board-Diy-Monitor-Kit-/110977522562
But i dont now, if the LCD interface description/pinout/communication are the same.
==> The seller answered that: The Nexus 7 LCD is not supported

I found out, that screen mirror ober ADB is very lagging and the second disadvantage is that i need always a PC (https://youtu.be/DTPR_wOXNcA).
I want to transforme the Nexus 7 to a Android PC ..

IPOD Cable

I have purchased an Xtrons PF75ATTA. As I understand this information is some what useless so other information includes (MCU Version: MTCD_GS_V1.75_1 and Build Number: rk3188).
As I am sure most owners of similar headunits find even basic technical support is some what limited. So to my question
On the back of the unit I have a 8 pin connector titled D: split machine 3 ipod. In the factory settings it says ipod = yes. and there is an ipod app as part of the stock rom.
xtrons tell me the unit doesn't support ipod but I get the impression that is not the end of it. The back of the unit looks identical to other units and the cable for a pimpkin hu device looks like the cable I need (Unfortunately I am to much of a noob to be trusted to post links at the moment). So I guess my questions are as follows
1. Does anyone else have a unit which specifies it doesn't support Ipod yet has ports for it (other than USB)
2. Has anyone successfully got this working?
3. If so where did you get your cable from or did you make it?
4. If you made it what were the pinouts?
Thanks

i could never get an iPod to work right on my Joying and when I posted on the Joying forum, seemed like no one else could get it to work either.
Prior to getting the Joying, I was emailing with RoadNavi.com's support about the S160 series, and they also said their units didn't really work with an iPod

With your joying did you have a specific ipod cable with ipod connector on one end and proprietary connector on the other end or were you using a standard ipod to usb connector and plugging it into the usb port? This can't be that difficult to do. My old Parrot Asteroid did it with no problems.

i used an iPod Classic with a 30 pin connector. I had a 30 pin to USB cord that worked fine in 2 different cars. I tried that on both the USB cords with no luck.
Road Navi does have an iPod specific plug and cable, but they said it didn't work right either

Yes, I can understand why a standard ipod 30 pins usb connector may not work. Can anyone share there experiences with a hui fei unit with dedicated ipod port and cable. Does it work as expected?

From what I have researched so far :- (Feel free to add or correct me) -
Standard IPOD Classic 6th gen works fine with the current Honda head units, which are still in the dark ages and running a Honda version of Android 6. !! (heavily LOCKED down so that nothing can be added with rooting)
Same device does NOT run on a Eonon GA2170B, running Android 8, even though the IPOD app is pre-installed, even when IPOD support that is turned off by default in Factory setting, is turned back on.
Turning on Ipod support still does allow Ipod Classic 6th gen to communicate with the installed Ipod App.
From what I have read, this is because the Eonon GA2170B is Android 8, and the "old" Ipod firmware is not compatible with the later Android versions.
There are Firmware alternatives for the Ipod (either permanent of via a dual boot), that claim to make the Ipods work with Android 8, with varying success, depending on the Model Ipod.
I have chosen to not mess with my Ipod, but rather to copy all its music onto a Mico SD card (or USB stick), and then use that in the Eonon unit with a suitable player, that can select Title, Album, Song, Artist from the Mp3's meta data.
Some many advantages of this are:
(a) Music is always in the Car,
(b) Ipod is NOT in the Car, getting HOT (or stolen)
(c) No need to worry about charging the Ipod.
(d) Far easier to add additional music (ITunes sucks )
I did find an OLD IPOD emulation Player app, that had a user Interface looking like the Classic Apple Ipod UI, but it was no longer on the Play Store, and when I got it from the author's website (5+ year old ), it also did not run on the Eonon Androis 8 unit.
BTW: My Eonon GA2170B is advertised as having 3 USB ports, but in fact it has 4 !
1 standard USB Port on the Back = USB 1
2 additional ports on a plug in cable to back = USB 2 & USB 3
1 Port on the front ( next to the front Mini SD port) USB 4
So, plenty of Ports to add USB storage devices with Music on them !!
