I want to connect a specific wifi network programatically using the ssid name, password and network type. For Android I found a solution: How do I connect to a specific Wi-Fi network in Android programmatically?
But for BlackBerry I can't find any solution.
If you are programming for BlackBerry OS 5 or above you may be able to use the HotspotClientRegistry.

I am developing the iOS application using objective-c.The main usage of the application is communicating with wifi enabled hardware device.It's uses UDP protocol.Now the problem is all the hardware device are connected with my office network and my iPad also connected with my office network.Now i want to list the available ip-address in the same network.So many duplicate questions are there but no place i found the solution for this.please help me.
Thanks in advance.
Mac OS application can find available ip-address in same network using command arp -a. Unfortunately, ARP doesn't support iOS.
But I recommend you this question would be helpful..
iOS - Get ARP table
Is it possible to send an ASCII code on an external device through USB port using IOS API? I assume that it is possible through bluetooth connection, but I'm not sure through USB connector. Any thoughts?
I would appreciate if someone could put me in the right direction.
Thanking you in advance
That largely depends on the level of sophistication of this "external device". If this external device is just a bare metal embedded device without some sort of operating system you definitely need MFI.
Otherwise, you can run a usbmuxd server (e.g. on Raspberry PI with Linux) to establish a connection via USB. Usbmuxd is basically the technology that Apple uses to communicate between iOS devices and Desktop apps such as iTunes or Xcode. And yes, it is App Store compliant, e.g., Duet Display uses this approach to make an iPad a secondary display for your Desktop via USB.
There are several open source libraries that provide a high level API, e.g., PeerTalk or DarkLightning.
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.
I'm looking into the iOS sdk for examples of the ExternalAccessory framework to use the iphone/ipad as an USB device that can be plugged into a PC or Mac and present as external device (like a midi controller or something else)
The App i want to create requires connecting to a host (PC or Mac) the iphone via USB or bluetooth and present to the host a functionality. How can i implement this?
You'll probably have an easier time connecting via WiFi. You need to be part of the Apple Made for iPhone program, which is not easy to get into, to use Bluetooth or the dock connector to talk to peripherals. There's no such restriction on the use of WiFi. Also, you'll find a lot more helpful examples of connecting via WiFi on the web.
CoreMIDI is the appropriate API for emulating a MIDI device, which may be possible over USB using Apples Camera Connection kit.
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.
