IS it possible to send data between two phones using WiFi only... That is without use of WiFi-direct, router and internet?
Are there any tutorials, Libraries or research papers ???
Well, that's exactly what WiFi direct is for... There are some other more esoteric possibilities as well, though I doubt your device supports them - check out the WiFi IBSS mode and BT HS protocol (it uses both BT and a 3rd-party RF, such as WiFi).
Yes.
If your a android user you can use this application
wififiletransfer
For IOS and other OS's they have their own WiFi direct apps.
If you a desktop user hope below article is useful

I want ot redirect my iPhone data to either wifi or Cellular. Based on some criteria. Is it possible to redirect whole of the iPhone data to a particular interface like to either wifi or cellular. ?
I heard that this can be done using VPN but no idea how it can be done.
Any help on this?
By default, iOS help you with redirection when you have weak/good WiFi and switch on in Setting - WLAN Assist
MultiPath is a technology switching automatically by OS
Just read this Apple Doc for more help.
You can't manipulate it easily with high level API.
After all, changing device data flow is kind of low level thing. Just like NetworkExtension is Apple provided. As far as I know, Apple does not mention it in public.
I have a device that can be communicated with over LTE with the same functionality as you normally get through BLE.
However, I'm having a hard time understanding how you communicate with, and get callbacks from an LTE device in the same way you do with BLE.
It doesn't seem that there is a library like CoreLTE but is there a standard way to use LTE like we use BLE (CoreBLE)?
In other words, how does one do essentially something line:
func lteCentralManager(lteCentral:LTECentralManager, didDiscoverPeripheral ltePeripheral:LTEPeripheral,
...
lteManager.connectPeripheral(ltePeripheral, options:nil)
...
NOTE: I realize that the technologies are different. The above is only meant to make the point of what I'm trying to do - not imply that the calls would be the same.
If there is no standard way to do this, does anyone know a good place to start figuring it out with iOS? I've read the standards. I'm just looking for how to use it now in iOS.
Thanks for the help.
iOS does not offer APIs to interact with the LTE modem directly, so this is impossible - not to mention, even if the hardware and software was capable of it, why would the scammercarrier allow you to talk to nearby devices directly instead of going through their network where they would charge you for that bandwidth?
If you need short-range communication between iOS and Mac devices you might want to take a look at Multipeer Connectivity. Firechat uses it successfully to enable off-network chat between nearby devices.
What is the fastest way to communicate between iPhones? I can get it to work with CoreBluetooth, using BTLE, but is there a way to transfer data faster, perhaps using regular Bluetooth rather than Bluetooth LE? I don't want to rely on Wifi, but I would like to be able to send data faster.
Thanks in advance!
As Anand said in the comments, the Multipeer Connectivity framework is the way to go here! It handles all ios device to ios device communication using whatever networks are available, be it Bluetooth or WiFi.

I have been using Upnpx library to discover the TV using Upnp protocol.
What I have to do now is to pare my iOS app with the TV as a remote controller.
The first objectives are to take control of the sound volume, move the mouse cursor, browse through web-browsers, etc.
I have tried to google for urn:samsung.com:device:RemoteControlReceiver1 specification but I had a hard time to find useful informations.
Has someone already done this before and could give me directions or the technical specification to control the TV from a remote app ?
Regards,
You could try to use Charles. That way you will be able to sniff your network. Then try to duplicate the functionality in your app.
Just for the people who will face the same issues.
I paired my iOS app to the samsung TV through TCP socket (I used GCDAsyncSocket to handle this) and using the great informations I found here :

I would like to develop an (personal) iphone app to use the iPhone as a controller for a small device such as a fan or for example a light bulb. Does anyone know if there is some kind of controllable iphone-dock to use for something like this. And are there some kind of methods to use with such a dock? For example the fan just needs a variable voltage for different rpm.
Thanks in advance,
EAAccessory requires that you become a Apple hardware partner, which is very expensive and not easy (this is why you only see large companies releasing hardware accessories for iOS devices).
There's a few ways around this. The easiest way is to have your app send OSC signals over WIFI to an OSC server. I've set this up before using TouchOSC on the iPhone and an Arduino connected to my desktop via USB. It's not hard at all, but it requires that you have an Arduino connected to a computer; it's not ideal.
Alternatively you can use audio output to send commands over the line output in the iPhone's dock connector, effectively turning the iPhone into a software modem.
Good luck and if you get this figured out, post the code on github. :-D
EAAccessory framework might not be what you want because of the requirement for you to have the license and hardware. You could better implement some sort of small webserver that runs an arduino or something similar. check this out for an example of that. on the arduino, you could just have a 5v relay to control the switch of whatever device and have the other pins of the relay connected to a hot (or cold depending on the relay state) standard 120v plug so you can plug anything into it. here is a good project for arduino controlled relay
for direct serial control, you could do something like this but it would require being jailbroken. i think for a personal app, doing it via wifi would be the best way unless you jailbreak and install the full bluetooth stack where you do not need EAAccessory stuff
Check out EAAccessory Framework. Used to handle external devices.
You could try using an ultrasound detector attached to your device, and playing an audio file at the appropriate frequency etc. on the iPhone.
