Hi i need an logic for wifi sharing:
On my phone I can allow users near to me to connect to my wifi hotspot. i want to share my wifi through application. Is it possible ?
It isn't possible unless you jailbreak your phone. The options to create a wifi hotspot are locked to carrier settings and are only available if you jailbreak your phone.

As title stated, basically I am building a Raspberry Pi to use Bluetooth PAN to provide device to device communication, I don't want to use BLE as it is not designed for high volume traffic.
As far as I know, it is not possible to initiate bluetooth pairing or connection to a paired device programmatically on iOS.
There are few exceptions however:
1. Pairing and connection to bluetooth external accessories (MFi) is possible using Bluetooth Accessory Picker and the External Accessory Framework
2. Core Bluetooth api can be used to communicate with BLE devices
For Bluetooth PAN profile, the only choice is to connect the devices manually.
You can for example activate connection sharing (hotspot) on iPhone and let the raspberry connect to the hotspot.
You can follow this link to set up hotspot connection sharing on iPhone:

I need to create an app read info from the ODB2 device installed in a car and show the data to the user but in a "funny" way. So I need to read the data and connect the phone to internet simultaneously.
I found this questions:How to communicate with OBD II using bluetooth or wifi using iphone , but is from 2014, maybe now there is something.
I've been looking for an ODB2 device that can communicates with iOS via Bluetooth.
I found a couple of devices that can do the trick (like viecar or bluedriver), but using their own apps. Also, I found some devices that can talk with iOS via WiFi, but it would be annoying to be connecting your device to WiFi, then turning off WiFi and using mobile data again...
So my questions is:
Is it there any way to communicates via bluetooth with an ODB2 devices? Or better said, is it there any ODB2 device that can be used via Bluetooth with iOS?
I´m developing an iOS App using Texas Instruments Launchpad CC3200. But the awesome SmartConfig feature is only working for 2,4Ghz WiFi Network connections.
Users trying to do SmartConfig on hybrid or 5Ghz only WiFi connections are failing.
Does anybody know if it is possible to programmatically determine what type of WiFi connection (2,4Ghz or 5Ghz) an iOS device currently has?
Unfortunately, this is not possible unless your device is jailbroken or if you have access to private headers in the API.
The only thing you can do is tell the difference between cellular and WiFi connection using the Reachability class by Apple. The networking tools are very limited in this case.
Is it possible to transfer files via iPhone hotspot i.e, iphone connected to a cellular network creates a wi-fi hotspot and one of the device is connected to that wi-fi and data transfer between these two devices over hotspot?
The iPhone has an app listening to some port or some medium through which the other device can send files to that iPhone app and record/save the files sent from the other device.
Any links or any information would be good if anyone of you can provide.
Thanks.
So this finally worked pretty easily using Apple's Multipeer Connectivity Framework.
Thanks to AppCoda's tutorial, here is the link:
http://www.appcoda.com/intro-ios-multipeer-connectivity-programming/
This tutorial doesn't talk about Hotspot usage, but I figured out a way to use the same to transfer files using personal hotspot on iPhone.
Steps to reproduce:
Install the final product of the AppCoda's on two devices. (This
might not work on Simulator for hotspot check, since no bluetooth via simulator)
Create hotspot on iPhone and connect the other device through the wi-fi created from iPhone.
Switch off bluetooth in one device and proceed with the app, browse for other device to connect.
Try to transfer files from one device to another through the hotspot connection.
Guess what? It worked for me. :) Go ahead. Try it out.
Is Wi-Fi Direct connection possible within iOS devices and among Wi-Fi Direct enabled devices?
The objective is to enable communication between an iOS device and another device (not necessarily another iOS device. It could be Android, Mac, PC) without the presence of any controllers. (WAPs).
iOS devices can connect to an ad-hoc network, and if they do so they will have full wireless network capabilities. The limitation is with creating an ad-hoc network from the device itself, which is not allowed/not possible.
An alternative would be to use the GameKit/Game Center API which uses Bluetooth to create a network between iOS devices. This would obviously include the more limited range of Bluetooth vs Wifi, as well as the constraints of Apple's SDK.
More information on Game Center in iOS 6 is available here: http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/GameKit_Guide/Introduction/Introduction.html#//apple_ref/doc/uid/TP40008304
I have been looking into this recently and from my research,(please see "Device to device communication with WiFi Direct: Overview and experimentation" by Daniel Camps-Mur,....) the WiFi Direct does NOT create ad-hoc network. It's actually creating a WiFi infrastructure network where one party takes the role of AP (soft-AP). Once this established, the network works much like a normal WiFi network. Do we agree on this?
Given this is the fact, Apple iPhone should be able to connect to WiFi Direct device that is already set up as AP. I haven't check this though.
Having said this, How can you get an Android phone like Samsung Galaxy S3 or S4 to act as AP? there is nothing in the settings as far as I know. If you connect two such devices, one of them will take the role of AP. Now, iPhone will detect the established network, but when trying to connect to that, will be asked for WPA password. Good luck finding it! Cus you can't get it from the phone. I read somewhere that a file in Samsung Galaxy called WPA_Suppliciant.conf has the WPA key in it but I didn't see it there.
I believe if you could find WPA password, you can get the iPhone to easily connect.
iOS devices do not support Wi-Fi Direct functionality, they do not have WFD (Wi-Fi Direct) group creation or role negotiation (P2P Group Owner or Group Client) support.
During a normal WFD connection one of the 2 devices takes role of Group Owner (Soft-AP) allowing other device to connect as a Group Client.
iOS has support for tethering which is normally know as Personal Hotspot option in Settings. It can be used for communication between iOS and non-iOS devices. For example,
Application ShareIt uses similar way to connect iOS to non-iOS devices by creating a temporary Hotspot and in the non-iOS device and promts iOS user to go to Wi-Fi screen and connect manually. This is normally recommended when a common Wi-Fi network is not present.
