nexus 7 USB radio FM

hello guys I wanted to ask if the nexus 7 support via the USB OTG FM radio
there someone who has tried it?

Yes, certainly!
Just get one of those cheapy RTL2832U based USB DVB-T dongles (they can be as low as £5.60 from eBay - http://www.ebay.co.uk/sch/i.html?LH_BIN=1&_fcid=3&_sacat=0&_from=R40&_clu=2&_nkw=RTL2832U&_sop=2)
Then download SDR Touch - https://play.google.com/store/apps/details?id=marto.androsdr
You don't even need to root your Nexus 7.

OT: Would it be possible to get some IR dongle from Ebay for applications that need it to work properly on Nexus 7?

And as an added bonus (other than bringing a one year old thread back to life), works as an scanner for aviation, police, HAM radio, CB (with a pinch of luck) and anything else in the ~25mhz to 1 gigahertz range. With a proper antenna, you can even capture weather satellite images.

[Important] USB OTG / USB2Go - host mode for Nexus 4?

View the last 2 pages for good information, ATM USB OTG DOES NOT WORK, but maybe (or propably) it is a software issue, which can be resolved...
View last pages
=============================================================
I think the last Nexus devices were able to host USB drives such as usb sticks etc., so do you think that it will be possible with this one?
16gb would be more than enough for me if I only use it for rom, apps, pictures and music but 720p movies won't have enough place (maybe just 1 or 2).
Is USB host mode maybe available for nearly every device (maybe only after another kernel)?
And I read somewhere that it is possible to host usb drives with "Nexus Media Importer", but it is also possible to access them via ES File Explorer for example or maybe even with Play Movies / Play Music?
At the moment I use HTC Desire (smaller movies at ~1gbyte), slowly it's time for an upgrade and this would be a must-have for me otherwise I won't buy it atm...
Maybe with USB OTG I could buy only 8gb, that would be really nice because 50€ (65USD) for 8gb is really expensive :/
Thanks for (hopefully incoming) answers

Planned to ask the same, but you opened a topic already

Also with this if anyone knows. Can you access a OTG source from a recovery like CWM or TWRP? That would make the 16GB meaningless.

Yes the Nexus 4 supports usb OTG (and you probably won't need a custom kernel for this)
Yes you can use ESFile explorer and run everything from your hard drive
I think latest TWRP offer OTG support but I'll probably never use it since you may "brick" your phone if the flash fail and not sure if otg is perfectly stable...

Thanks for the answer :good:
Is the USB drive automatically mounted?
And is the media on it displayed in medi player apps like Music or MX Player or do I have to click on each single file with ES file explorer to play it?

Where have you got this information?? I can say out the box OTG is not working. Anyone have any ideas yet?

Would it be possible to have a Nexus 4 case with a microSD slot that connected via USB OTG?

For me an attached normal USB Flash Drive (8GB) did not work. Even the light of the flash drive did not a single blink.
I am not sure if the Nexus 4 provides Voltage for usb devices.

Just to confirm, the Nexus 4 does not support USB OTG out of the box. Just tested it myself - works fine on the missus' Galaxy S2, but not on my Nexus 4.

I'm fairly certain that you still need to be rooted for it to work properly, as with the Nexus 7.

There's an app called "nexus media importer" on the play store for otg

It is listed as "not compatible with the device"

definitely does not work

i've read/heard somewhere that not all usb otg dongles are the same. some work better than others? i ordered a cheap 5 pin on ebay. don't have n4 or the dongle yet to test.

Hope it does cause if not...not buying it.

[Q] get mouse working broken digitizer

Ok need a little help with a nexus 4 with a broken digitizer.
Everything looks like it works but no touch.
Cost 150+ euro to fix, not going to happen buying a nexus 5.
But would love to use the nexus 4 as a media player with xbmc.
I just need to get a mouse working and then I am good.
BUT HOW?
how do I get a mouse running on this thing I have a OTG cable, I have plugged in a power usb hub.
But I get nothing.
Any help please
King Regards,
JP

There's no way to set it up without a working touchscreen. Your best bet is getting a friend with a Nexus 4 to let you borrow their N4. You replace the board and setup everything using the touchscreen to automatically connect to a bluetooth keyboard and mouse and then put the mobo back in the bad nexus 4 and there you go.
Or you interested in selling it?
Also, for OTG you need to flash Franco Kernel and use it's companion app (nonfree) to enable it. Not sure of any other way to do it. That also requires a touchscreen.
I think maybe your best bet is somehow installing a VNC server for android. Maybe via ADB install? *shrug* You can flash recovery and that will remain fully usable without touch.

that kinda sucks.
what you offering for my nexus?

If you still have a problem/your nexus 4:
if you aren't rooted, find out how to root [nexus root toolkit], if you have fastboot already it should be a breeze
You need a usb-otg Y cable so that power goes to the phone
install franco kernel and ziddey mod (search forums should come up quick cuz they are awesome)
then should work like a charm (plug and play)
My nexus 4 runs a mouse and 1tb hdd off an externally powered hub, but I could never get it to run with my normal otg cable only the Y cable... I think it's because nexus needs the power surge to know it is connected or something (more complicated that I don't understand).

[Q] Wacom graphic tablet via OTG, possible?

Hi, I bought this tablet because of the stylus and the drawing capablilities, but on youtube I stumbled across a video where one guy attaches a wacom graphic tablet to a Nexus 7 and works even with pressure sensivity, I tried this with my EVGA Tegra Note 7 but didn't work, do you guys know if there is something I have to do before connecting it via OTG? maybe I have to install Wacom drivers to the tablet. The wacom lights up when I connect it to the tablet but doesn't recognize it like a mouse input.
The title of the video in question is "Google Nexus 7 Tablet & OTG Cable for USB Host Connection" I can't post links so please search for it :silly:.
Thanks in advance.
Please forgive my english, is not my natural language.

It's possible the Nexus 7 had a custom rom installed with some kind of drivers added. Impossible to tell without the video. All (well, almost all) of the source code for the Tegra Note 7 is available so that you may compile your own version, including drivers if you find any. I doubt that the stock AOSP kernel supports Wacom tablets out of the box.

On Linux (and therefore Android), the drivers are part of the kernel, so unless someone develops a kernel with the Wacom drivers included, it won't work. Perhaps someone could take Shaky's kernel source and add those drivers and see if it works? I'd give it a go except any time I try anything involving code, a baby unicorn dies.

Yeah it happens to me too, Peta sued me for the unicorns. But a friend of mine that has the same tablet is helping me to make it work, we have the drivers (I think they are the right ones) and maybe we can get it to work.

Can someone can try "Headunit" ?

Hello everyone !
If I understood well, it's possible to install Android apps on a Nook Touch ?
If yes is it possible for someone who has a Nook Touch to try this app : http://forum.xda-developers.com/general/paid-software/android-4-1-headunit-android-auto-t3125252
It's an app to connect a Android phone using "Android Auto" to a tablet. I really want to know if this is working as the EINK displays are way better to put in a car (for the sun) and we don't need a high refresh rate !

Nope. It says it's for Android 4.1+
The NST runs 2.1

Too bad .
Thanks.

Of course the new Nook Glow Plus would probably work, it's 4.4.2
It's a quicker display than the old Nook and at 300 DPI, sharper too.
Also, the light is pretty good.

That's good to know !
Does someone has it and can test this app ?

It works. Well, it installs and give a nasty error message about not supporting USB Host Mode (Renate can probably help understand what that all means). Attached is a screenshot...

Not to dissuade you from your pursuit of an eink unit for the car,
but the Nexus 7 2013 is a pretty good device, nice car size,
good USB host working already, Marshmallow (6.0) and you can find them new for $150.
In any case, I'm certainly interested in getting USB host working on the NGP.

I already tried tablets in my car but same problem with any phone : the sun .
I have a cab, so I'm looking for a screen which can be used if there is a lot of light ! (and I also like to play with new things ...)

It's funny, I've never had any dealings with the USB API in Android.
I've just used the underlying Linux layer.
I wonder if there are cases where there is actual USB host mode, but the Android API was never implemented correctly?
The simplest test for basic host connectivity is connecting an OTG adapter and a regular USB keyboard.
The shift lock key should turn the shift LED on and off.
What does the headunit software want to talk to over USB?
Could it be done over a serial link instead?

Ah sorry I did not understand your question.
For this you need to plug a smartphone (android 5 at least).
It transforms the tablet in an Android Auto display (like a radio).
But if you have technicals questions about the app you should see with the developper, I'm only a single user .

Oh, I'm a little slow on the uptake.
The idea is to just mirror the display on your separate mobile phone?
I looked a bit more into the USB host mode.
I could be wrong, but it seems that the PCB is not even populated to connect the ID pin on the USB connector.
Of course there must be some software hack to force it into host mode.
