I have QNAP NAS (TS-431XeU) and 8 SAMSUNG TVs (ue43nu7192u) and I would like to connect them via LAN and play media files from NAS.
A single connection is OK, I just plug in ethernet to TV and setup it, this is fine.
But I would like to connect 4 TV together to create one big screen, is there any way how to achieve this?
With the possibility to use them separately and connect them together to act like one if needed?

I'm looking for a way to managing and controlling IoT devices without the (constant) need for a remote server to be part in it and with a PWA instead of a native application on the managing device. The resulting goal is an IoT device that keeps working when a product eventually goes obsolete (no more server running/allocated) and having an application that has PWA benefits like always up-to-date, easy to replicated and cheaply hosted on something like S3.
As an example, let's say I have one or more IoT devices of different classes like an ESP8266 and a Raspberry Pi for instance. Just as with any new IoT device I want to add it to the network and from there on manage its state from an app. The app in this case is a PWA instead of full blown native app.
1) Traditionally, in the initial setup a native app would scan for wifi networks, connecting automatically to one that has the right name. Using PWA's we are limited to just the "state" of the network. So users would have to manually switch to the network of the newly connected IoT device. This is okay.
2) Next up, the user would need to enter his/her wifi credentials. There might be methods to set this up automatically using a native app, but I don't believe this is the case on a PWA. This, also, is okay.
3) The device then restarts, tries to connect to the network set up in (2). If set up correctly it should get its IP using DHCP. And now things get difficult. I want to 'discover' that network from my PWA. There used to be a way to retrieve the IP from a device using the WebRTC API. but that since has changed to show an obfuscated mdns that resolves to localhost. The ip leak would have allowed for a browser based network scan, but that is no longer possible. I always hoped that Android would default to using a users router as a DNS server, but that is not the case. The result is that simply using an mDNS isn't an option either. I do not want user having to check their router, install an app like fing or do anything else that disrupts the flow from a UX perspective.
Step (3) needs to run every time the app starts so you'd want something reliable. Scanning for devices isn't possible using a PWA, so I need to find another method. I was thinking of something like the way Docker containers can find each other in between networks (see etcd for example), using a predefined key that is shared during installation. The problem with this, is that it requires a remote server to store the IPs attached to that key. I don't want that.
Ideas on how to solve this are very much appreciated! I want to be able to offer a solution that would work even when WAN is out. That being said, I am aware that a connection to a remote server is needed if the end user would want to enable any voice assistant or wants to control a device from WAN.
I have downloaded and installed an extension to preview a webpage I'm working on inside the editor. It works fine, but I would like to also test the same HTML code on my mobile device as well. I have a normal home WiFi network. I was wondering if it is possible to somehow hook into the preview from another device besides the host computer. Is there a way to view the website from my phone on the same WiFi network, and access all of the website's served files, like index.html, /styles/.css, /scripts/.js, /images/*.jpg, etc?
Thank You!
very simple solution
turn on the live server on your pc
check the port where it's running
will look like 4400
check your LAN IP address will look like 192.172.123
Enter the address with the port number in this form (192.172.123:4400) on another device connected to the same router or device
Boom you can view changes as same you are using the same device
Sorry, I didn't realize that this functionality is already included in the wonderful extension that I originally downloaded - it's called Live Server by Ritwick Dey. On his GitHub repo, he outlines steps to remotely connect to the served website via another device on the same network (your phone for example). Tried it and it worked the first time!

Hello I am trying to work out how to set kodi up on my smart TV. My main problem lies with the TV being on the wall in another room too far away from power sources. She has sky installed and that was situated in the other room and with a HDMI lead fed under to floorboards to the other room by a professional someone or other. I am unable to feed another HDMI lead along the line.
Is there a way I could connect kodi by some other means to the TV? I am not really up on these things.
At the moment I have the kodi box in another room and I have to switch the sky lead to the kodi box to use. Also this means you have to be in the other room.
Can anyone suggest a way for me to get kodi working on the tv and be able to operate it via remote control?
I use Kodi on all of my TVs through an amazon fire stick. Most smart TVs have a USB on the back of the TV that can power the fire stick while its plugged into the HDMI so you wouldn't have to worry about power. I have a Sony bravia that will control the fire stick as long as I am on the input the fire stick is plugged into so no need for an additional remote.
To start off this is the wrong place to ask. This is a Q and A platform for programming questions and coding related questions.
To give you an answer though because I'm not a dick the best way to do it would be using a NAS. You would have two Kodi boxes but one media store.
I'm not sure which device do you use.
In my case, I installed Kodi on my Raspberry Pi(RPi) and TV and RPi are connected with HDMI. My TV is Samsung SmartTV, which supports HDMI-CEC. So, RPI can get RCU Key input from TV.
(HDMI-CEC allows devices connected to your TV through HDMI ports to communicate back and forth with your TV. )
In addition, you can customize keymaps for remotes in GUI by using the community Keymap Editor add-on.

Check your TV supports HDMI-CEC, first.
I am having a wifi Harddisk , just want to connect and access the folders and document of wifi Harddisk from my iPhone through wifi and without using internet connectivity.
I want to create similar application mentioned below url:-
http://itunes.apple.com/us/app/goflex-media-seagate-technology/id431912202?mt=8 ?
As per GoFlex Satellite™ User Guide you can browse the HD contents with a web browser.
You (or your user) will have to manually connect to GoFlex Satellite WiFi network - it looks like this device starts it's own AdHoc network. Sorry to say it's not possible to automate this process from code - at least not without using private API's.
You can test if this works like this:
- connect to GoFlex Satelliti WiFi network with your iPhone
- open www.goflexsatellite.com in Safari
You can do this also from code using UIWebView.
A nice tutorial on using UIWebView can be found here - just remember to use www.goflexsatellite.com as a target URL.
Am I missing something glaringly obvious or is there no way to debug an iOS app which uses an external accessory that's connected via the 30-pin dock without using a bucket load of logs etc. I want to be able to use things such as breakpoints and Instruments.
Is there a way to remote debug perhaps, over Wi-Fi, Bluetooth?
Note: Yes, I asked this very recently and I deleted it because I thought I found the answer.. but the answer was only Instruments has support over Wi-Fi.. not Xcode debugging. So the question still remains...
And so...: Given that I've had no real luck finding the answer, and no one has given me an answer as yet - I take it that it is a big fat NO. :(
Makes me wonder are we just expected to magically guess where bugs occur, or log the crap out of everything while wearing out our dock connectors by continuously moving it back and forth between the device and accessory?
Time to file a bug report I guess.
At CES today, I talked to a developer from Wahoo Fitness that makes an ANT+ accessory for iPhone. They had this same problem, but found a solution.
They found a pass-through dock extender that has a mini-USB port. They used the mini-USB port for debugging while the accessory was connected.
The product they were using is http://www.cablejive.com/products/dockStubz.html
This blog talks about remote debugging iOS with a dock accessory attached
You could connect the external accessory to another iOS device (not the one tethered to the Mac running the Xcode debugger). Then tunnel all your EA framework messages from the accessory connected device to the device running the app being debugged over a pair of wifi sockets. Look at the code for tunneling accelerometer messages from a device to the iOS Simulator (a common trick for debugging game code on the Simulator) for one example of how this could be done.
After further researching, and having seen that people had to do sending strings over Wi-Fi to get around this, I'm concluding the answer is no.
I have filed a bug request for this.
In the mean time, it seems like the Wi-Fi logging, and on-device text logging will be the way to go for now.
Here's my understanding for why just the USB protocol works for some external accessories and doesn't for other external accessories. Looks like a fundamental problem, without an arbitrator, two masters can't talk to a single slave over USB, a serial Master/Slave protocol. So XCode is one master, the iPhone is the slave device. If the external accessory is a master too, one won't be able to connect the iPhone (Xcode slave) to the second master (the external accessory).
Probably the Wahoo Key for iPhone" is a slave device and that's why the dockStubz solution works for such an external accessory.
I have tested the dockStubz. It doesn't work for my external accessory. As suspected, the USB protocol can't be used to have two Master devices controlling a single slave device. Trying to hook up a Mac (Master) (via the mini USB ) & an external accessory (Master) (via the 30 pin connector) to the iPhone 4 (Slave) causes the iPhone to go in loop of connect & re-connect.
Following looks promising too, though expensive: digi.com/support/kbase/kbaseresultdetl.jsp?id=485.
Has any one tried to use USB to Ethernet connectors and use a router to route requests from two masters (XCode & External Accessory) to the slave (iPhone)? I am off to Best Buy to purchase USB to Ethernet cables and hook all three on to my IP router. Will report if it works.
This is what will be needed :
http://www.bestbuy.com/site/IOGEAR+-+USB+Ethernet+Extender/9614781.p?id=1218131339965&skuId=9614781&st=USB%20to%20Ethernet&cp=1&lp=1

So connect XCode mac using the male end into the USB slot of your computer. . Use a ethernet cable to connect this to a router.
Connect the iPhone to the female part of the IO gear connector. Connect it to the router via ethernet cable.
Connect the external accessory with the male connector (Sabrent USB to Fast Ethernet Network Adapter.) Connect it to router.
I am still researching if this will work. Just ordered the parts. Will get it by Friday & will report back then.
Update:
The IOGear male end draws too much current when connected to router. Also, the female end can't charge iPhone when connected to the router even when 5V USB current supplied.
So tried to directly connect the iPhone to the USB slot of the router (used for printers). It does charge the iPhone. Also used USB to Fast Ethernet Network Adapter (BestBuy had one to connect Wii via USB) to connect the Mac to the router. It did connect to internet but couldn't find the iPhone. In the router client list I don't see any login entires for the iPhone. So this experiment was a failure unless someone have other pointers.
