[Q] Wifi-Direct, USB-OTG

hey guys! does anyone tried this functions on razr i?

theres no wifi direct option...
havent tried otg

No USB-OTG @stock. If I plug and USB stock, nothing appends
Maybe with something like Stickmount
About Wi-Di, as it's an Intel Device, maybe can we hope some support on day. I don't know if the Medfield SoC is WiDi compliant.
The Lenovo K800 is WiDi, no reason that the Razr i will no be..

I am so longing for USB OTG.... can't wait to use DSLR Controller with this cell phone.
:/
Maybe Motorola will release a ROM that includes USB Host functionality?

Mmmh, still no USB OTG with JB.... dammit

I've heard OTG doesn't work because the razr I as it doesn't output any power and usb devices need power, I have ordered a lead which has a separate lead to supply power to the usb device and I'll update when I receive it and have tested.

So the lead came and to my sadness doesn't work for my razr I :'(
I was looking forward to that too

I'm currently using an powered OTG cable to connect my mouse and keyboard on my xt890.
the pen drive is not working im gonna test some mods on that,

OTG is working but only devices like mouse, keyboard, pad etc. USB drives doesn't work cause kernel has no option for that. To use OTG You need to connect devices through powered USB hub.
Wysłane z Motorola RAZR i.

For WifFi Direct you can use this app : SuperBeam
Cheers

I tried it but failed to connect with Galaxy Mini II.

Did you switch on your WiFi ? Even for me it works only on certain devices but most of the time I forget to turn on the WiFi.

Yes I did. :/ It fails starting to transfer file.

Hmm. That's weird. Maybe you could try their IP Address method. I'll have to get back to you later because I don't a spare android smartphone. If it works I'll give you a description of what to do. Maybe its the new upate that's causing it. You could also try an older version of the app.

USB DAC and Nexus 7 2012 wifi only

Hi there just joined this wonderful forum and basically i am an Andriod noob :victory: I am very late to the party and never owned a smartphone or andriod device but with people going for the 2013 Nexus 7 and offloading their 2012 models at a basement bargain price i finally decided to jump on the Andriod bandwagon
Ok here's the thing : i bought a 2012 wifi only Nexus 7 and the seller stated that it has been rooted. I have a Fiio E7 USD DAC that i am using at home with my desktop and with the laptop @ the office. From what i read with some tweaks a Nexus 7 works fine with this particular USB DAC. Thing is i have downloaded apps like games, ebook reader, FLAC player, etc and more importantly files. From what i understand i have to "flash" to a new kernel that is USB DAC friendly? Could someone dumb it down so i could understand what exactly i should do to achieve this? Would all my files be lost if i flash to a new kernel? Thanks in advance ya

Hi, hodak...
Much of your post doesn't mean much to me I afraid... although I do remember reading years ago, that DAC stands for Digital-to-Analog Converter and FLAC stands for Full Lossless Audio Codec (I think)... but that's about the limit of my knowledge concerning technical digital audio related stuff.
With regard to "flash to a new kernel that is USB DAC friendly". I have no idea if such a kernel exists. But if one does exist, it will almost certainly be in .ZIP format (which, by the way, you don't unzip), and would be flashed via a Custom Recovery.
There are two such Custom Recoveries available; ClockWorkMod Recovery (CWM) and The Windows Recovery Project (TWRP). They both do pretty much the same thing... with such a Recovery, you can flash Custom Kernels, Custom ROMs, root your device, and perform Nandroid backups (which are 'carbon copies' of your Nexus 7's state at the time the backup was made... even right down to the last app icon or widget you last dropped onto one of the home screens). Nandroid backups are extremely useful for returning your device back to it's last working state, in the event of a ROM (or kernel) flash gone wrong.
If you've never used a Custom Recovery before, you're probably wondering which one is 'best'. Well, the answer is a rather unhelpful 'neither' . Like most things Android related, it's very much a matter of personal taste. CWM has been around for years, and is favoured (mostly) by Android old timers. TWRP is the new-kid-on-the block, so to speak, and has a more intuitive interface than CWM, so I guess I would recommend TWRP as this is your first foray into Custom Recovery related stuff. Anyway here are the download links...
(It's important you get the right version for your device, so if you have a WiFi only Nexus 7 (as you do), you're going to need the 'grouper' Custom Recovery...and 'tilapia' Custom Recovery, if your Nexus 7 is both WiFi and 3G capable. Download the correct one to your PC.
TWRP for 'grouper'
CWM for both 'grouper' and 'tilapia'
But before you can fastboot flash a Custom Recovery, you must first unlock the bootloader on your Nexus 7 (and this is the bit you're not going to like so much)... unlocking the bootloader, performs a full wipe akin to a factory reset. So before proceeding you must first back up everything that is important to you on your Nexus 7 to your PC or some other external location.
However, none of this might be necessary!.
In your post you say "...and the seller stated that it has been rooted.".
Unless the seller rooted the device via the motochopper 'exploit' then there's a very good chance the bootloader is already unlocked... which means you won't loose your stuff. If there is an unlocked padlock symbol at the bottom of the screen, underneath the Google logo at boot... it means the bootloader is already unlocked.
So, to summarize...
* Backup your Nexus 7. (Might not be necessary if the bootloader is already unlocked).
* Unlock the bootloader with fastboot oem unlock (Might not be necessary...).
* Fastboot flash a Custom Recovery with fastboot flash recovery custom_recovery_filename.img
* Using that Recovery, flash your Custom Kernel.
* Restore your stuff back to your Nexus 7. (Might not be necessary...).
To reiterate... if the bootloader is already unlocked, then only the third and fourth steps listed above are necessary.
The full details of how to use fastboot and a link to the necessary drivers are available here. It looks more complicated than it actually is... but that's only because Comminus (the OP of the thread) is thorough in his explanation, and covers a lot of ground.
--------------------------------------------------
One other possibility occurs to me... If you're already rooted, you can use either one of these two apps...
Flash Image GUI or Flashify.
...you can use one of these two apps, to flash a Custom Recovery DIRECTLY FROM THE NEXUS 7 itself, without recourse to a PC or the need for fastboot. Just download the Custom Recovery .img file from one of the links above, directly to your Nexus 7... and then use either Flash Image GUI or Flashify to flash it.
Once you have CWM or TWRP installed, you can then download, directly your Nexus 7, the Custom Kernel of your choice... boot into CWM or TWRP and flash it.
How to boot into your Custom Recovery
Shut down the Nexus 7 completely. Press and hold VOL-DOWN... whilst holding, press POWER ON (hold both for about 5 seconds). This will boot the device into the bootloader. Using the VOL-BUTTONS, navigate to the RECOVERY MODE option, and press POWER ON to select. Your Nexus 7 should now boot into your previously installed Custom Recovery... CWM or TWRP.
--------------------------------------------------
And that's the Cliff Notes/Reader Digest version of how to flash a Custom Kernel. All you have to do now is find one that fits your digital audio requirements... and that, I'm afraid, I can't help you with... unfortunately.
Hope this helps... and good luck.
Rgrds,
Ged.

I think this rom might work for you
"USB audio kernel driver enabled
USB audio plug&play patches for DAC plugged at boot"
"USB audio plug&play handler for DAC plugged post boot"
"Supported USB audio devices
These are just some of the supported USB DAC's: CM106-F, FiiO E07 + E10 + E17......."

I won't iterate what's been said, just add a few things you may find useful.
In addition to a kernel that support USB Audio (here's the one I use), you'll also need an OTG cable (On The Go). I just got this one to replace a POS cheapo cable. The StarTech is rock solid and, for my $$$, worth the price. I'm pretty sure most FiiOs work with the N7, but you can always google to be sure.
If you any high resolution FLACs (24-bit, 96 or 192 kHz), I'm pretty sure this is the only player that will play them at their native bit depth and samplerate. I'm just getting into USB audio on my Nexus 7 2012, but I tested the trial version of USB Audio Recorder Pro (UARP) with my HiFimeDIY Sabre U2 Asynchronous DAC, and it played a 24/96 FLAC perfectly. I haven't had a chance to test USB audio with any other players, but UARP is unique in that it has its own USB audio driver that bypasses (or attempts to; no problem w/the N7) the Android audio chain.
There's this USB-centric ROM available, if you're inclined to explore. Seems quite popular and has some nice features.
If you have a lot of apps installed, Titanium Backup Pro might be worth buying. It can be handy for restoring apps if you decide to try other ROMs. There's a free version, too.
Lastly, as a noob, you might appreciate WugFresh's Nexus Root Toolkit (NRT). Handy if you don't want to use the commandline and Android SDK. I started with it, learned the principles behind what it does, and now use the SDK for most things, but sometimes his NRT comes in handy.
Hope that helps! Good luck

ThurstonX, I'm actually thinking about buying the Hifimediy Sabre U2 but had a question. Say if I was playing 16bit mp3 songs or using Google Navigation...would you actually hear sound through the Sabre or does audio only work through UARP?

Wish I could answer your question. I never got the DAC to work with any other player. I use the stock 4.3 ROM and vorcers' V7 kernel. I have Timur's USB ROM (which uses his kernel) downloaded, but haven't had any time to test it. Hopefully tomorrow, but whenever, I'll post another reply to let you know.
My understanding is that if you get the DAC working, it handles all audio out, if you have a player that will do it. Maybe that's why people love USB ROM. I mean if guys are using it for their Nexus 7 car installs, with Bluetooth and other audio apps, and are using USB DACs, I would assume all audio will go that route.
Sorry for being so vague.

External DAC

Does someone tried an external dac on the G2? Does it work? Every DAC is compatible? I ask this because I have to buy an USB DAC for other purposes and, before buying, I want to choose one (if exist) that can be compatible with g2

You'll need to provide more details. Are you trying to OTG connect a DAC? If so, it probably won't work. Those not intended for Android use will not contain drivers for Android phones.
If you're looking to buy a NuForce Icon or FiiO E18, those will work because the G2 supports OTG, and the majority of custom ROMs retain that functionality as well.
So just post what DAC you're looking to buy. You're got every reason to be forthcoming. There's no way to tell without knowing the specific model DAC. If it's intended for Android use (i.e. the manufacturer advertised it as compatible) then it should work.

There quite a few that work with both nexus 7 ...so i wouldnt thinkg it being g2 would matter as long as its comptatible with other android over otg should work for g2 ..... Im getting a fiio e17 or e18 soon.
Sent from my LG-D803 using XDA Free mobile app

I don't have a dac but I need to buy one to be used with my hifi. I don't have choose a specific one and I ask here if there is someone that tried and get a dac working on g2.
Edit:
I have a usb headset, the corsair vengeance. That is not a dac but act like an external sound card. I connected it with usb otg cable and get the sound, but only the music played throught 'usb audio player pro' trial version. Is possible to get all the system soud directed to the external sound card/dac?
Edit2:
Found this thread

That means that we need modified kernel?

I have an fiio E17. It works with the G2 but i have clicks sometimes. For more than 16/48 I need USB Audio Player.

Hifimediy Sabre Asynchronous here, on CloudyG3 with the included kernel. Works fine, clicks sometimes when I start playback.

Got rid of clicks with the following additions to build.prop, normally used for Viper4Audio:
lpa.decode=false
lpa.releaselock=false
lpa.use-stagefright=false
tunnel.decode=false
Edit: False alarm unfortunately. But I have much less of them.

although this is a G2 FOrum I have a G3...
was looking for some answer to find out how to get rid of all the clicking or pops with an Asynchronous DAC/AMP. I have a HRT Microstreamer.
Anyway to fix or we all waiting for L?

Here dorimanx dev made a kernel that supports audio out to every usb device, so now every dac or usb soundcard are supported.

And here no lags or microshutters.

NuForce uDac 2 works well. Tested also cheap Beyerdynamic's USB soundcard and played too.

[Q] Connecting HTC One to LAN port

I would like to connect the HTC One to a LAN port via a usb-ethernet adapter, for wired internet access.
I know some phones such as Nexus 5, and tablets like nexus 7, 9, 10 have the functionality.
Does the CM on HTC One have this functionality? Can it be loaded?
Thank you.

Very much so.. I've done it myself using a USB otg to ether adapter.
With a off and root with the rom of your choice (revolution, coin etc) - install the kernel from flar.
Elemental × version 14/20 depending on whether you're phone is Google edition, sense 6 or 7.
The kernel allows all sorts of capabilities. I have even played games using xbox gamepad. This kennel recognises way too many things to list.
Long as your ether adapter is compatible with an average win 7 or Ubuntu then it should auto install drivers on phone. Certain Chinese cheaper accessories aren't recognised as their chips are probably incompatible.
Any search should get you to the download link. Read it, understand it thoroughly before flashing kernel. Nothing should happen if common sense is used. I'm not aware of your experience in this so just letting you know not to yell at me if something is installed incorrectly. ?

Thank you for the reply and information. It is great to know such a possibility exists.
Unfortunately I am totally new to this, and have no clue how to install kernels or change settings at that level!
If you would know of a tutorial on the web that is geared for novices like me do let me know.
Also, are there kernels to enable using the ppp2 widget with a usb modem for phones?
Thanks again,

External screen?

Hey!
This is my first thread I've ever created, so don't be too harsh on me
As far as I know, the new Android 10 includes a so called "desktop mode". So you can connect a compatible device via USB to an external screen. I think thats pretty cool and samsung already implemented this idea from the S8 upwards with Samsung Dex.
I understand that this needs USB 3.1, but the Motorola G7 Plus only has USB 2.0!
According to the datasheet of the build-in Snapdragon 636 processor, it does support USB 3.1!
So here comes the question: Is it possible to "activate" the required functionality in order to use the desktop mode?
So like changing a few things inside the root files (Like you can activate for example OTG)?
If not, is the hardware build that way, that it just doesn't have the data-lines?
And also, if all of that doesn't work, you surely saw such USB 2.0 to HDMI adapter, which do work on older computers, but do they might work with Android 10 connected to otg?
It would be really cool if something of that might work.
Thanks for your response!

Thanks for your answer. But I knew that before. I am trying to finde some "workarounds" for this, because I do really like this phone!

Found a solution
So, after a bit of research, I found a solution to add external screens to any OTG compatible Android phone!
There are so called "DisplayLink adapters" and those seem to be compatible with any Android phone that supports OTG.
After installing the official app "DisplayLink Presenter", you should be able to get everything working.
I din't tested it yet, but I hope that this will help someone in the future.
