Hi guys! I don't know if this thing belongs here, but since I'm an owner of a Blue Angel device, I'll put it here anyway. Is it possible to create a simple device which has the following components:
- An IDE adaptor (don't know if this is the right term, but what I mean is a cable which can be connected to standard HDDs', CDROMs', etc.)
- A power input to provide external power to the HDD or CDROM connected to it.
- A bluetooth radio allowing a device (PDA, cellphone, laptop) which is bluetooth enabled (like my Blue Angel) to connect to it via bluetooth. I think the directory bowsing profile, or network profile should be supported.
The purpose of such a device is to allow my Blue Angel to read CDs' and copy data from hard drives. I know it would mean carrying an extra device, but considering the advantages it would give me (reading CD's and HDD's without the need for a PC) I would surely consider adding it to my gadget bag.
Does such a device exist? If not, is it possible to make something like this?
Sorry, but it can't be done. The Blue Angel's USB port is only a USB Slave port, meaning it only works if plugged into a computer.
I dont think a bluetooth drive adapter exists, but maybe something wireless could be used??
e.g.

I would also suggest WIFI. Bluetooth is way too slow
Toshiba used to sell a Bluetooth hard drive called the "HopBit". I don't think it was ever sold in the US but Dynamism imported it for a while. It seems to be discontinued though.
Is there a way to get midi input recognized on our phones? On my pc I use the rock band 3 keytar connected via a midi to usb adapter and I can do midi playback.
Is there a way to do this on our phones via an otg cable?
EDIT: got it done! check my post below.

it works beautifully and way easier than I expected.
connected my otg cable and the phone said usb connector connected (since when is this a thing!?), plugged in the midi-usb adapter to the otg cable and right away it prompted me to open with the software I linked above and another midi software I had installed.
and bam, it was working. I messed around a bit to find the better settings for my keytar, but this thing works. over Bluetooth and with the headphone plug. there's a little bit of lag over Bluetooth but for my uses I wanted it straight to the speaker so i'm using the stereo cable. now I don't need a pc to get sound out of the keytar.
mark this as one more day i'm amazed at what my phone can do.
by the way, it functions as a synth using the software I mentioned above, so I can play harpsichord, organ, piano, etc. and the sound keeps on playing even with the screen off.
happy camper = me.

Looks like you had some luck... Wondering if you can help me?
I am trying to make my Android, Huawei p20 Pro, accept a MIDI signal via USB too.
I have an OTG adapter, and have tested 2 OTG adapters and 2 cords.
All work into my PC (even via an USB type-C to standard USB adaptor )
The issue seems to be that I cannot select the USB in type to be MIDI.
I have also experienced that on another Samsung Galaxy S10
I have tried opening developer settings and changing the setting "Disable USB Audio Routing" ON as per https://help.joytunes.com/en/articles/2636638-troubleshoot-midi-on-your-android-device
I have tried using it with 3 apps that accept MIDI.
Simple Piano by Joy Tunes, FlowKey and USB MIDI Monitor
Any ideas?

Does anyone know if it is possible to get a digital audio output from this tablet? Stereo is fine - don't need surround sound or anything fancy, although that would be nice too!

Yes, I was surprised that when I plugged my Fiio E17 in it just worked with the standard LG ROM. Recent custom ROMs also now support USB audio.

You need a USB "on the go" (otg) cable, £1-2 from famous "auction" site.
Then (something I haven't used) you'd need a USB to coax converter - which seem to exist. I just tried a cheap (£11) USB sound card that I have and it happily converted the USB output of gpad into optical or analogue (not coax).
An alternative could be to look at a Bluetooth solution.

As you say it seems like an OTG connector plugged into a sound card would do the trick. But is there a more direct method? E.g. my old laptop has a straight digital output. I am trying to avoid latency apart from anything, as one application would be to use it at the same time as Miracast (my surround sound pre-amp is very good but doesn't have HDMI so my blu-ray player's HDMI goes to a projector, and the sound is handled separately via coax - works surprisingly well). Would like to replicate with the LG.

I've not come across a tablet with direct digital audio out via optical or coax. This is now a different question from how I originally understood it (I assumed just wanting to listen to audio).
Can't you get the audio via Miracast (I'm not getting it ATM but I thought it did when I've tried previously)? I suppose it really depends on what you are trying to play and what to, there are all sorts of possibilities.
I use the Netflix and YouTube apps on tablet to control play on recent Samsung tv / Chromecast dongle (not actually streaming). You can play audio/video via dlna to appropriate players, you can stream to Apple TV with appropriate app. etc..

I guess I have two needs, one for straight audio which now seems fairly straight forward (and thanks for your help), and then it would be nice to get video as well. I thought the LG was Miracast, not Chromecast or can it do both? Either way I would need to get a dongle for HDMI into my projector, and separate sound to the audio processor.
But how would it do DLNA? My Sony blu ray player BDP-S570 does DLNA and that would be a really neat way to do the video as it would handle sound at the same time...

Miracast is the screen mirroring system, Chromecast is Google's dongle for playing some streaming video sources on TV. Matching apps on tablet/phone can control the playback on Chromecast, some recent TVs use the same control protocol (DIAL) so their respective streaming apps can be controlled in the same way

I use the BubbleUPnP app, it discovers media servers and playback devices on you home network and allows you to control play. It also acts as a dlna server itself, so video stored on phone/tablet can be played on dlna player (TV/blu ray/streaming box/other mobile device).
Note that dlna doesn't guarantee playback, the rendering device needs to understand the format of media from the server, the more recent the equipment the greater the chance of success (eg my recent TV plays streamed video better than the two year old bluray player, my 4 year old TV won't even play video via dlna but will music and jpegs).

So I can buy either a Chromecast HDMI dongle or a Miracast HDMI dongle and both should be compatible with my LG G Pad? I see in Settings on the LG there is a Miracast toggle, but no Chromecast setting. Sorry - I guess I am a bit ignorant about all this! Ill try the DLNA when I get a chance...

It really depends exactly what you want to do.
Miracast mirrors the tablet display, so anything you see on the tablet will appear on TV including games (but lag is too much to really be usable for this).
Google's Chromecast dongle doesn't allow you to show any random video, there needs to be a matching Chromecast app. (I've only used Netflix and Youtube). You start the matching app on the tablet, tap an icon and choose where (on which device) to view the video, you can then pause/play rewind etc. using the tablet.

Thanks again. I get the difference between the two, but I just want to make sure that my LG G Pad is compatible with both Miracast and Chromecast dongles. I have to say that these dongles don't get very good reviews on Amazon but I guess Ill have to get one or the other ...

If you don't mind the cable you could use a Slimport adapter to get HDMI out of the USB socket - have never tried it so don't know the pros/cons.

That could well be the way forward - at least it should work! I am surprised there are not people commenting on miracast etc.
I accidentally sat on my galaxy note 8 yesterday (damn it) and the screen is now broken... i cannot see anything (part of the screen is dark and other part is "scrambled") ... anyway I now want to convert the device into an android tv device as repair will cost too much...problem is I cannot navigate with the device touchscreen as I can't see nothing....
what do i need to completely convert it into an android tv? software, cables, etc... I bought the mhl hdmi cables from ebay but none worked... recommend me the correct cables to buy plz.. thx
You're in a "catch 22" scenario, you could use an OTG cable and a mouse, to enable Bluetooth and pair to a Bluetooth keyboard and mouse, but you can't see the screen to make the pair and you can't use the MHL cable and the OTG cable together.
You'll be better off getting a new screen off eBay and replacing it yourself.
Sent from my SM-N9005 using Tapatalk
no way to "navigate" using adb something like that and set up a bash script that outputs/tv mirroring with mhl?
Replacing the screen seems quite pricey (I am going to use that money to buy a budget chinese dual boot android/win8 tab instead)
As for using it as a TV...
Seems like the stock video player does pass 1080i 30pfs well, all other players paid or not only passes 720p.
As most all streaming services push 720p as High Def, using 1080i would be very rare, and with today's standards to allow Cable to choke our internet. There is a monopoly going on, and if it were the 70's Comcast and Verizon would be heading to court just like AT&T.
You can get a MHL HDMI adapter, and use it to use a TV to connect. I have a Samsung TV, so Anynet+ will automatically turn on the TV and switch to the input when connected to the tablet.
All you need to do, is make sure the MHL HDMI adapter is connected to the USB power before connecting to the tablet. You can either plug in the MHL adapter before powering on the tablet or plug in once the tablet has been booted up. If plugging in while off, give it a few minutes to display on the TV.
The nice thing is that the adapter will work without need of any settings changes. I use Miracast as it does not need cables and works a wee better. Though many complain about how it functions, i think it is because of modded ROMs and the lack that they do not use Samsung's update to fully optimize the workings of their tablets.
If using Miracast, you will need a MHL adapter to configure the tablet for syncing... once configured you wont need to connect the MHL adapter. Though if any Miracast settings get changed your not going to be able connect and use your tv, since your tablet's display is broken.
I prefer a stock ROM, as it is fully working, and don't having to fix what others break.
thx for the reply but the problem is I cannot use the screen as it's broken... any ideas are welcome
ok guys some progress!
using
https://code.google.com/p/androidscreencast/ and http://www.mymobiler.com/
I am able to control my galaxy note 8 from pc now with a usb connection
https://code.google.com/p/androidscreencast/ is straightforward but it is very slow and could not get keyboard and mouse to work. I used it to install mymobiler app and grant root access to it... with mymobiler, i can use mouse and keyboard and it is faster but still lags... if anyone knows better/lagless screen mirroring app, let me know.
Now, next step is to connect physical bluetooth mouse and keyboard and hdmi so that i can use it as an android desktop/tv pc

You may have to check for PC mode on your telie... My Samsung has the capabilities to run PAL or NTSC through the PC input or HDMI 3, though it is undocumented. Once set at PC, you may have it sync properly.

My TV was made in 2008 and has 3D capabilities... Since it is Samsung, there are some features Samsung uses with HDMI connectivity. Such as AnyNet+, as it will detect and switch to the input automatically when connected.
Samsung has a few hidden features on my telie that not all telies have... even within their product lines.
To enable DVI/HDMI for PC use, you must go into the user menu to label the inputs.
There are preset labels, one being PC. That has to be set on HDMI 3 or a DVI/HDMI input.
If your teli has a DB15 SVGA connector, you may have to use an inline HDMI to Analog converter. As used in older projectors.
There can be issues right away, since Samsung uses AnyNet+ and other features within HDMI 3.1 Spec for the tablet and telie.
These issues can be the lack of detecting the tablets output or visa-versa in linking. Also modded firmware don't pay well at all for me.
I reverted to stock so I can use all the features that the tablet offers without having issues.
The stock video player does a great job at delivering 1080p @ 30fps, I wish MXplayer did that, but it comes in handy for video formats that the stock player can't do. The best I can get from MXplayer is 720p @ 60fps. So it seems that MXplayer may be an option if resolution detection is not syncing between stock player. Also the tablet does a great job at converting frame rates with all video players.
Another hidden and undocumented feature, is that my telie even being yank, will do Euro frame rates so I have the ability to play all frame rates, 24, 25, 30, 50, 60, and 75. Yes 75 fps... only when using PC enabled on DVI/HDMI. So I can push odd frame rates without a conversion between DVD/Blu-ray players if connected using PC analog connections or just connecting a PC to play videos.
As for connecting... I plugin the MHL / HDMI adapter to the tablet and then plug in the power adapter to the side of the MHL adapter.
Some telies will deliver 5v though the HDMI cable to power the MHL to HDMI adapter and tablet. Mine is too old and does not deliver 5v though its connection.
Hopes this helps with understanding some limitations with telies and connecting the tablet.

Hi, I think I mis-understood about the monitor connex... Not all monitors have full HDMI security built in. HDCP compliance may be your issue.
I suggest taking your tablet with the MHL adapter to a store to have the sales person assist with finding a monitor that will work for your needs.

Yes it will work on any Monitor with HDMI.
Just TV was on the top of my head when making a quick setup.

Depending on Monitor settings, some will auto fit or allow for edge to edge adjustment.
Also if using video player, the Samsung video player does do edge to edge, while MXplayer will not through MHL. I gave up on Per App settings in Xposed, before I could ascertain that MXplayer will do edge to edge with H/W or Software decoder.
One thing with SecondScreen, it may adjust for proper scaling with Monitors, though with my TV the built in PC input scales to have a boarder to compensate for the 5% overscan most all TVs use to keep encoded signals from showing at the edges.
Not all Monitors and TVs are perfect, but I am able to use edge to edge with some adjustment with the display or using a 3rd party app such as secondscreen.
what is secondscreen? I can't find it on playstore ... yup when i play youtube, it plays full screen... will try to play a game.. I am glad I have been able to convert my galaxy note to an android tv! lol ... another issue though... my monitor does not have speaker ... so there's no audio atm.. the galaxy note does not seem to output audio when connected via hdmi?

Well the other option is to connect your tablet to your A/V receiver and pass the video to your monitor, or to get a signal splitter that will allow audio output. Depending on the quality and performance they can run as low as $20 and up to $150 so in some ways it is best to get an A/V receiver. If your A/V receiver is limited by inputs BlueJean cable has various HDMI switchers.
I have the link to the free app a few posts above this... just read the pages back till you find it. I am running the paid version so updates may be faster and better than the freebie. I went a head and updated to 1.4.5 just to see how much of a problem it is as for workarounds with Touchwiz. I still prefer 1.4.4 as it seems smoother at transitions between on and off / off and on. May revert back and just keep the old version as it does its job very well in automatic mode.
I can't find the link to Secondscreen app. Will check out if i can get a cheap av recevier

One note about secondscreen... it will shrink the display to have borders. Some TV / Monitors have zoom or scan adjustments to remove most of the borders.

I want to know if Fire tv rooted would be perfect for my requirement. I plan to use this as audiophile audio streamer. It already have the most imp thing i want . A Ethernet port to connect to network (can't use wifi) , and USB port (to Audio output from it). Things i am not sure is and reason for asking help here is following.
- Can the USB port can be used to output Audio that would be connected to a DAC. This is main reason.
- Also can we switch audio from USB to HDMI ( case when i want to use FTV2 for watching movies)
- IS there a remote app that is available so that i dont have to turn on the TV for selecting songs.
- Once rooted i should be able to install any app , specifically USB Audio Player PRO.
Thanks

anyone?
I just did it...
I think it doesn't work or at least it's not that simple.
I have an audioquest dragonfly that works well with my LG G3 running stock marshmallow rom and my fire tablet.
I side loaded USB Audio Player PRO trial. It seems that you don't need root to make it work.
The DAC goes into error when I plug it and remains in error even after I start USB Audio Player Pro...
I think it's better to have another DAC with optical input.
