I need to install a physical network adapter on the Holo2. I purchased a high-quality adapter from a reputable vendor. I've looked everywhere and Googled quite a bit but can't seem to get an answer. The adapter does show up under the 'Devices' section, but if I click on it, nothing happens. Also, if I try to add a device myself it never finds it. I just get the screen that reminds me to turn it on make it available.
Any guidance is enormously appreciated!
If the device requires additional drivers then there could be a problem if you would see connect devices. You should check the information provided in the associated chapter regarding your device.
Does it have to be an adapter on the Hololens itself. I would rather suggest an Ethernet to Wifi Adapter on the PC, if this is in any way possible.
I hope this helps in any way.
Networking should just work plug-and-play. If you need help with your device please open a support case at http://aka.ms/hololenssupport. Device configuraction issues are off topic on StackOverflow.

I want to create a TAS that can play the Nintendo Switch games that are only compatible with the joy cons.
There are turbo pro controllers in the market but there is no turbo joy cons, so my next idea is one of two:
To use the Bluetooth to connect a devise that I could control with my PC and can be connected to the Nintendo switch via Bluetooth (or USB) and trick it into thinking that it is a joy con and not a pro controller.
Use the idea above but the devise is the joy con itself, in this case, I would have to connect the joy cont to the PC and command it while it is still paired with the Nintendo Switch
Is there any way to achieve what i'm looking for? Thanks in advise.
Also, if there is a better branch in stack-overflow to post this question I will move it.
Looks like it's already been done, and you'll need a product called vJoy.

Looks like you'd need to reverse engineer the communication protocol used by those controllers and then emulate that protocol with software. Here is a resource I have found regarding RE bluetooth. Another one I have found here. Redfang may help you in that endeavor, it is software that helps you find bluetooth addresses of devices that you you can't discover normally.
Another idea I would have is to open your controller and solder on some wires to a micro controller, such as an Arduino, Raspberry or something similar to the buttons and analogue controllers and 'input' the commands that way.
Unfortunately I can not offer you any more advice. I hope this helps in some way.
One possible way is to use JoyCon Droid app in Android to controll the Nintendo Switch. If this app can work, it should be possible to make one as PC software too.
Luckily, there are a few easy ways to control Android from PC such as using AirDroid which allows you to touch the Android screen from PC. You can refer to How to remote control Android device from a computer with AirDroid?. It can both mirror the screen and give you the touchscreen control, which you can utilize it to control the JoyCon Droid app.
I've just found another way which is to use a microcontroller as a USB controller here.
I have a Raspberry Pi that acts as a BLE peripheral. I want to add Apple's HomeKit Accessory Protocol (HAP) to the Raspberry Pi's BLE code, to control the BLE device using Homekit. I would like to avoid implementing HAP over the internet.
The closest resource I found is https://gist.github.com/KhaosT/6ff09ba71d306d4c1079. However, this gist makes it seem like there are many unknowns with that process.
Does anyone know if this is possible? If so, any info or resources would be greatly appreciated. Thanks!
As mentioned at https://developer.apple.com/homekit/ under Accessory Developers, you need to first sign up for MFi and then you will get access to all the resources you need in order to implement homekit. All source code you can find publicly online is against Apple's license since they prohibit public redistribution of documentation and source code of implementations.
Is it possible to make a computer behave as a bluetooth HID device? That is, given a local machine with a standard USB keyboard plugged into it, other devices could discover this machine and use it as a bluetooth keyboard.
I'd like to create a linux or OS X application (or use an existing one, though I've found none) which can behave as described above, but I'm not sure where to start, or if it's even possible.
So:
Is what I'm describing possible?
Are there any existing applications that do what I describe?
If no application already exists (I'm assuming not), are there bluetooth libraries or bindings that will help? (I'm pretty comfortable using most of today's popular languages, so I'd prefer a library most directly suited to the task, so long as it's available in linux or OS X.)
Failing any of the above, the bluetooth spec looks pretty dense. Are there specific guides or other starting points applicable to the problem at hand that I can read?
I realize that such an application would most likely need to steal the normal keyboard input, possibly providing some KVM-like hotkey for switching between providing input to the host operating system and sending the input over bluetooth to the connected device, but I'm considering that problem to be outside the scope of this question.
It is definitely possible on Linux. Some time ago I found this project:
http://nohands.sourceforge.net/index.html
They emulate a full-blown headset with audio and keyboard controls on the Linux bluetooth stack. If they can emulate something like that, you would probably be able to emulate something simpler like a keyboard.
It is possible, however I don't think I'll be able explain it very well and I don't know the entire answer. A BT HID device works as a server and waits for connections to come to it. In linux, using the bluez stack, first you would have to advertise the HID service for other devices to see. I think you do that using the sdp.h and sdp-lib.h header files(the second header maybe called something else, I'm on a windows computer and can't check). So you would have to add the HID service record to you computer for other devices to see it. You would have to create a program that first adds this service to the record, then waits for other devices to connect, then handle the pairing process, Bluez might handle this for you, or you might have to do some things to it, I'm not quite sure. You should also read the Bluetooth HID Spec found at the http://www.bluetooth.com/English/Technology/Building/Pages/Specification.aspx site. This document contains the details of the SDP record relevant to HID. Also the book Bluetooth essentials for programmers is pretty good to introduce you into bluetooth programming
I would like to have given a more concise answer, with more detail, but that's all I know ATM. I am also trying do something similar, but spare time is so hard to find ;) I'm also not on my Linux box and can't check all the details. If your are still interested, let me know and i'll try to expand my answer.
I don't know if this is helpful, nor if it is still alive and working, but perhaps you could try this link.
Another one that might or might not be helpful in some way is remuco, but I don't know if they are using a Bluetooth HID profile.
It is indeed entirely possible with Linux and Bluez. See: https://github.com/lkundrak/virtkbd/blob/master/btkbdd.pod
Try Across, unfortuantly for me my phone was lacking support.
I recently downloaded a barcode reading application for my phone, an LG KU990i (AKA the Viewty) However, there's a problem that renders the application nearly useless: the Viewty has 2 cameras -- the main one, and a secondary camera located on the face of the unit -- and it is the secondary camera that is unfortunately set as the phone's default video capture device. As you can't point the secondary at anything and see what it's pointing at at the same time, it makes it a bit difficult to snap a barcode!
According to the JSR-135 spec, it is possible to specify a video capture device other than the default... if you know the device name. This does not appear to be documented anywhere on LG's Web site, nor does the JSR-135 spec describe any way of enumerating the devices on a phone... or is there? Failing that, are there any naming conventions for video devices commonly in use that LG might be using?
I've logged a ticket with LG, but as it's an old device, I don't imagine them breaking their backs in getting back to me... I should also point out that this is purely for my own curiosity so no-one here should feel obliged to break their backs either!
As far as I know there is no way to get list of all available catpure:// urls.
All urls I know:
capture://image,
capture://video
capture://devcam0
capture://devcam1

LG responded to my support ticket. Apparently, it's not possible to access the primary camera on the Viewty from Java, making it pretty much useless for barcode scanning. Answer reproduced here for search engines.
You support ticket has been answered. Please visit the LG Mobile Developer Network and login to check the answer at [My Page > My Tickets].
KU990i default video capture device is the secondary camera
Answer :
Hi,
KU990i have to Two camera module
differently.
Main camera using Joran chipset and
sub(front camera) using Qualcomm
chipset.
Joran chip doesn’t supported JSR135.
Therefore, we couldn’t supported to
the JSR135 using for main camera.
(it is H/W limitation)
It was inform to operator already and
we remember operator was confirm it.
So that, we only supported sub camera
for JSR135.
BR,
I want to send almost 4k size data to any cellphone by using bluetooth.
Firstly to do this, I need to find what stacks are in my phone and what stacks are acting when I send a data.
I really struggle to find the way; however, it is really hard.
If you know how to find it, please give me some information!!
See http://32feet.NET if you are talking about Windows Mobile. It is a managed library for Bluetooth, OBEX, and IrDA. We support both the Microsoft stack, but also have support for Widcomm. And now also Bluesoleil and Stonestreet One Bluetopia.
You can either send and receive the data as an OBEX message, or over a simple bluetooth connection. See a copy of the user's guide at http://www.alanjmcf.me.uk/comms/bluetooth/32feet.NET%20—%20User’s%20Guide.html
Goto "https://www.bluetooth.org/tpg/listings.cfm" type the name of your mobile. This will give you information on the Bluetooth stack inside and the profiles supported.
