will we ever get screen mirroring? - Nexus 7 Q&A, Help & Troubleshooting

From what I understand, Miracast support is off the table due to the wifi hardware on the current gen of nexus tablets. With that said, do we expect to ever get screen mirroring support through WiDi, the pogo connections or the micro usb port?
I know that these guys, http://esrlabs.com/ , had created a custom rom for the n7 and raspberry pi such that the n7 could screen cast and the pi would recieve. However, I reached out to the developer and understand that work has ceased since Miracast was announced.
If the consensus is that this capability will not come to CM/AOKP in the near future, then I'd like to sell my n7 and get a tablet that does or will support mirroring (i'm willing to invest on hardware on the reciever side - but between the tv, xbox, cable stb and raspberry pi I'm finding that my home theater receiver is running out of spare hdmi inputs /firstworldproblems ). I do not want to invest in a 1 off product that is not a standard, like a MirrorOp receiver.
So what are your thoughts? Is something coming to the N7? If not, what hardware and software should I get instead?

Universal Remote?

Looking for a remote I can use with my TV (not connected to the internet ) to control smile functions such as channel and volume up and down power and input. Is it possible to download one from the play store or side load one if there is none? I need it to work on a Samsung plasma tv.
I appreciate your help!
I don't believe the Nexus 7 has the required IR Transmitter to accomplish this. If, however, your TV supports Bluetooth, then it very well may be possible if your TV company has released an app to do this.

[Q] Nexus 7 as display for TV dongle possible?

Hello everyone,
I am attempting to set up a Tronsmart MK908II TV dongle as a portable sandbox and web development environment. For my first attempt I'm using the stock ROM and apps from the app store such as Bit Web Server and Terminal IDE. I've had a fair amount of success, though very tempted to install Pi****u (Ubuntu) for a more powerful environment.
One of my main objectives have a miniature HD monitor so I can have direct access to the device if necessary even when I'm on the go. Before I go out and buy a suitable device for this, I'm trying to get my Nexus 7 to act as the display, since I will always have it with me and it's the perfect size. I believe I may have all the necessary cables and converters to make something like this possible... I'm just a bit stuck at the moment on getting it all to work as I want and I suspect its a software/config/capabilities limitation more than a physical one. I have already attempted this a couple of different ways, including using a USB cable from the dongle and an OTG converter for my Nexus 7, but could not get the Android USB Serial Monitor Lite app to recognize input from the dongle.
Does anyone know of any tools or knowledge that might help me achieve this? I can probably find an app that will allow me to remote control my dongle from my Nexus, which is plan B, but it's far less desirable since there are some circumstances that a purely software solution might not work from the dongle end.
Thank you for your time!

[Q] OS and BT questions

Okay, the first question is aimed at Mad Catz Rich as from what I gathered he is a Mad Catz rep.
Can we expect an OS update to the MOJO? An update to at least 4.3 is important because of FSTrim which seriously affect performance in the long run.
The second question is about the bluetooth and aimed at anybody who can answer. Supposedly the MOJO supports bluetooth but I've also seen mention of a dongle. Do you actually need the dongle to use the controller or is it only for when connecting it to a PC (if it's a requirement it eats up an entire USB right?) So does bluetooth on the device work without the dongle? Can you easily connect devices such as a mouse and a keyboard?
I'm interested in the MOJO but gaming is only third on my list. I want it more as a low power (HT)PC running android so I want to know if my logitech K810 (great for only using one keyboard when switching between the phone, tablet, and PC) would work on it and an actual mouse would be nice since it might take a while to get accustomed to using the mouse mode on the C.T.R.L. (plus I saw some comment somewhere where the person was concerned with the durability of the switch as it would get constant use and a mouse would avoid the need for constant switching).
I'm not sure whether to wait or not as game compatibility is only semi important for me for me (plus I have several humble bundle android games which might avoid the need for play store compatibility). But video playback is important as is the keyboard and mouse. If those work then despite the limited game selection it might be worth it for me.
We have connected a BT keyboard and mouse with no problem to ours. Logitech keyboard, Microsoft mouse & both work well. Neither use a dongle.
I do have the controller's dongle taking up a USB port, but not sure if it actually needs it...I just sort of plugged it in because it was there and I'm a fan of sticking things into other things.

Thanks! And yeah, many people are of that practice...
Now let's just see if Mad Catz Rich can give us some info on the OS front.

Controller has built in blue tooth. Just flip the switch the the far left(blue tooth) and hold start button for 5 seconds. Controller will light up and seek nearby Bluetooth devices and sync.

I use this mini BT kyboard/mouse:
shinatro Mini Bluetooth Keyboard
Works fine, a bit treaky to get used to but very functional.
I haven't tried removing the BT smart dongle, I would say it does need the dongle for the controller only because of android 4.2.2 doesn't support it.
On the new egg TV vid, there's confirmation of Android 4.4 kitkat coming, so I guess that's coming, and when it does the dongle wont be needed on the mojo, as from 4.3 it does support BT smart natively.
Well that's my understanding.
Hi,
The CTRLR included with MOJO has Bluetooth Smart built in, allowing it to take advantage of lower latency and lower power consumption from the Low Energy profile of Bluetooth 4.0. Unfortunately, the Android OS won't be able to take advantage of this until KitKat is made more widely available. So, in the meantime, the USB dongle is included to make up for this connection. This will be similar for other Bluetooth Smart devices that don't have the OS/hardware matching up yet. The Bluetooth 4.0 built-in, however, is backwards-compatible with all Bluetooth Classic connections.
Regarding USB ports, using a USB hub should be just fine for connecting additional USB devices. Ie, wired keyboard, wired mouse, usb dongle wireless keyboard or mouse, xbox 360 controller, external hard drives, thumbdrives, etc.

When will you be updating MOJO to KitKat?
No news to share regarding this yet. Sorry. :C

Just to clarify this even further, whilst 4.3 adds Bluetooth Smart support it doesn't have support for all Bluetooth Smart profiles. 4.4 adds support for HID over GATT which is what's needed for Smart mice, keyboards and game controllers.

Hi MC Rich, happy new year
Thanks for the clarification.
Oh the same HID over GATT which iOS has?
I know it's not officially supported, but I did try pairing with iPhone5, but it didn't find it.

Gamepads have to be specifically created for iOS in order for them to work so, no dice there I'm afraid. The CTRLR will pair directly with one of the following:
Android device running 4.4 + Bluetooth 4.0 chip
Windows 8/8.1 PC with Bluetooth 4.0 chip
Macbook running Mavericks with Bluetooth 4.0 chip

Yep - I did say directly
With the dongle, of course, you can connect it to anything that supports a USB gamepad (and which doesn't require some other form of authentication, such as Xbox 360), which even includes a Playstation 3 (although the button assignments will be all kinds of wrong).

That would mean, I could use the controller with my LG G2 and Nexus 7 ? Both are supporting USB gamepads, keyboards and mousecontroll.
If the Mad Catz BT dongle would act like any other wireless to USB keyboard transmitter, it should work " out of the box ".
That's not the case.

It should be - the dongle conforms completely to the HID USB standard so it doesn't do anything funky or out of the ordinary. That said, I've noticed on our Nexus 7 that sometimes you have to unplug/replug the OTG cable a couple of times to get it to recognise correctly, depending on the OTG cable that you use. You can tell if you've got a good connection because the home button LED should illuminate blue rather than flashing.
So yes, provided you've got a good OTG cable and all other things being equal it will work on any device that supports USB game controllers.
I've used this OTG cable on many different devices. It's definately full working. Before my former post, I have rechecked if my wireless keyboard with USB dongle works. Sony Sixaxis on USB are fine working. On both devices. Both devices even have enough power output to run harddrives.
The LG has JB 4.2.2 and the N7 has the actual 4.4.2 running. The controler simply can't pair.
In terminal lsusb didn't even list the dongle as recognized device.

It's clear that it's not getting initialised through that OTG but can't explain why that is happening, I'm afraid. If it's working through your M.O.J.O. then we know it's okay and we don't do anything specific at all on M.O.J.O. to support it - it really is just a USB HID compliant dongle.
Strange, if I connect the bt dongle through a passive hub, it will be recognized by my G2 and N7.
It's not a really handy solution.
edit:
I bought another OTG cable and now, the dongle is recognized to my LG G2 without the HUB.
So, you're absolutely right. The C.T.R.L.R USB-dongle should work with any device. :good:

sm-t580 with video-projector

Hi,
I have a SM-T580 and i'd like to connect it to my video-projector (it's a basic projector with hdmi/mhl connections).
My goal is to do some android application demonstrations.
I know that it doesn't support MHL so i can't buy a simple micro usb to hdmi cable. And after reading a lot of things on the internet i'm getting a little lost.
There a similar question here but it's for smart TVs https://forum.xda-developers.com/galaxy-tab-a/help/samsung-galaxy-tab-support-screen-t3177088
For the moment i think the best choice would be to buy a miracast or a chromecast but do some of you already have a similar setup ? because i don't really wan't to buy it if i'm not sure that's it compatible with my tab A. And what do you recommend between miracast and chromecast.
If i missed some possible solutions i'd love to know them.
Regards,

Nvidia Shield TV questions

I am probably going to buy one of the 16gb Nvidia Shield TVs but I have some questions or want feedback if I am on the right
track with this.
I currently have a Roku Premiere Plus(with problems with HDCP 2.2, etc) but it works with the Spectrum App which gives me local channels that
I think the Shield can't do or can't do easily without side loading the app with bugs.
I have plenty of IT hardware(have worked IT for 40+ years) so I will probably use one of my spare PCs as a Plex server...can I connect an OTA antenna
to that(locate it near the antenna) instead of having to route coax through my house to the Shield? I am also on the distance border for this at about
45 miles from nearest towers(Rochester, NY).
Is a separate Plex Server better as I don't need additional hw attached to the Shield but can still access it via my Meshed WiFi environment(Ubiquiti)? Or
will my wifi performance be slower than a usb 3.0 connected drive on the Shield? If I don't go with a separate Plex Server then should I go with a powered
USB Hub to allow more toys to be connected to the Shield at one time?
I will add the Rii keyboard to ease use...any best ways to manage a single(recommendations?) universal remote to get down to just one remote for my
TV(Samsung 4K HDR), Denon AVR, Shield, Samsung BluRay DVD player, etc? I also have two XBox 360 controllers that I will add to my list of things to
try after figuring the device out better.
What else am I missing? Thanks in advance for any feedback/tips.
