could i connect iPhone and collect data from other bluetooth device (it may be iphone , ipod, nokia or other blue tooth device, like PC and so on.) from my own application. ?
if it is possible which way is the easiest . like GameKit framework ?
pls help me
With the SDK the GameKit framework is your only choice.
You are not allowed to low-level access to Bluetooth devices, also knowing apple and their policy on connecting external devices to their iPods, it would take some kind of chip and licensing deal for a vendor to be able to connect their device to an iPhone. So I am guessing that not all bluetooth devices will be abble to connect to your iPhone

I have a requirement - I need to connect the my iPhone application with external Bluetooth Devices like (Thermometer, Oximeter) without External Accessory and I need to transfer the data with my application to Bluetooth Device. Is it possible? Can I connect my iPhone to any other devices (not a Apple device)? Is anyone aware of this?
if you are asking for connect bluetooth with any other bluetooth than its possible from now.
in ios apple introduce core bluetooth for connect with external bluetooth devices. The CoreBluetooth framework provides access to Bluetooth 4.0 low energy devices. but its support after ios 5.0 .
you can get more information and demo source code for it from below url.

hope this will help you.

After searching on Google, I found that people say it's only possible to connect an iOS device with a non iOS device with the 'MFi program'. Is that true?
My project is mainly focused on sending and receiving information with the Arduino device via Bluetooth directly.
Is communication between iOS and non iOS devices without jailbreak possible? If yes, is there a reference?
(I viewed Stack Overflow question How can an iPhone access another non-iPhone device over wireless or Bluetooth?.)
As I stated in the above-linked question, general Bluetooth communication to external devices on non-jailbroken iOS devices is restricted to MFi-compliant Bluetooth hardware.
However, newer iOS devices (iPhone 4S, new iPad) are capable of Bluetooth 4.0 LE communication with external devices without the need for those devices to be MFi-compliant. This interaction is done through the new Core Bluetooth framework, which lets you send and receive arbitrary data to and from Bluetooth LE devices. This only works with those listed newer iOS devices, though.
Tim points out an interesting hack that you might be able to get away with in making your device appear like a Bluetooth HID keyboard. Devices like this barcode scanner have special modes to appear as HID devices to iOS. You might be able to pull something together based on this, but all data transfer will be one-way from your device, and it looks like this will require entering that data into text fields as if you had a keyboard connected.
Alasdair Alan's "iOS Sensor Apps with Arduino" is a good resource to look at. I've used Wifi with another microprocessor (mbed) but not sure about bluetooth. Alasdair is active on Twitter and he usually is kind enough to answer questions.
I'm trying to make an iPhone application to communicate with an other wireless device.
The other device can send datas via UDP sockets. I just want to know if it is possible to receive the informations on the iPhone, without access point on the network (just an iPhone and the wireless device), and how if it is.
I was looking at UDPecho, by apple, and I think it could be useful.
If anyone had some idea, just let me know what you're thinking about
iPhone 4 with iOS 4.3 can create a Wi-Fi network using the Personal Hotspot feature, which your "other device" could join.
A Verizon iPhone with 4.2.6 may also be able to do this.
Earlier iPhone models can't use the Personal Hotspot feature, regardless of the version of iOS.
I'm trying to figure out if an iPhone can connect to another non-iPhone device over wireless or Bluetooth and have seen conflicting information. Much of what I've found was before version 3.0 of the SDK came out, when it certainly wasn't possible. Looking at Stack Overflow questions, like Can the iPhone 3.0 SDK provide full access to Bluetooth devices (headsets)? mention you can't connect to an arbitrary device unless if it's part of the "Works for iPhone" device. Do I need hardware that is part of this program?
Looking through the Apple documentation, Peer-to-Peer Connectivity, it mentions connecting two iPhones, not an iPhone to another Bluetooth device. Then there are articles like iPhone SDK focus: Bluetooth enhancements that includes this quote
...and with the newly-announced "standard support" should allow file transfer between the iPhone and a computer, as well as between nearby iPhones
Another Stack Overflow question, GameKit in iPhone SDK 3.0, mentions Bonjour, and the Apple documentation for Bonjour talks about connecting to Bonjour devices, but can an iPhone connect to any Bonjour device? Does it have to have a Wi-Fi connection, or can it use Bluetooth?
Even if I could use Bluetooth to connect to another device, it won't be available on first generation iPhones and iTouches, I believe. Is that correct? I'm thinking of an iPhone application that would need to communicate with other non-iPhone devices in the area, probably using Bluetooth, but possibly a direct wireless connection. What are the possibilities and limitations of this approach? Is it not possible to have an iPhone connect to an arbitrary Bluetooth device? Does the other device have to be on a wireless Bonjour network that? I'm trying to figure out if it's even possible for this to work or if it's not worth the effort.
The only way to communicate with other Bluetooth devices via the External Accessory framework in iPhone OS 3.0 is if they are in the Made for iPod accessory program. Even though they communicate through standard Bluetooth connections, accessories need special hardware in order to process the data stream coming from the iPhone / iPod touch. Unfortunately, this means that your idea of communicating with generic Bluetooth devices won't work on iPhone OS 3.0.
If the devices you want to talk to are Bonjour-discoverable via Wi-Fi, they don't need to be part of the Made for iPod program. However, that doesn't sound like your case.
Third-party developers in the near future may produce dongles that connect through the 30-pin dock port and give access to existing Bluetooth devices. If these developers opened up their communication protocol, that might enable your goal of communicating with these devices.
You can use NSStream for opening IPv4/IPv6 sockets on the iPhone. The devices to which you're connecting do not have to be iPhones or use Wi-Fi necessarily. Because of how network communication protocols are laid out, you simply don't have to care what kind of device your iPhone is communicating with.
Bonjour, on the other hand, uses NSStream internally. It's basically a nifty little wrapper which allows for auto-discovery. You need the Bonjour protocol installed on all devices which you want to participate in the auto-discovery process. There is even an implementation for Windows.
As part of the iPhone OS 3.0 SDK, Apple announced the ability to control hardware accessories through either Bluetooth or the dock connector. The dock connector supports standard protocols (that is, play, pause, etc.) as well as any custom protocols the developer wants to implement.
As far as connecting via Bluetooth, you can talk to other iPhones or other devices. For example, you can use stereo Bluetooth to connect compatible Bluetooth stereo headphones, car kits, or other accessories.
As far as what devices support Bluetooth communication, everything except the first generation iPod Touch should be okay.
See also Apple's page on iPhone OS accessories.
we can connect by bluetooth only iPodtouch or iPhone using GKSession and GKPeerPickerController right ? , or can we connect other bluetooth device ?
Bluetooth communication using GameKit (GKPeerPickerController and GKSession) is limited to iPhoneOS devices.
You can also use the internet instead of bluetooth, but once again, you are still limited to iPhoneOS devices.
If you are interested in using External Accessories, I suggest you check out Apple's Documentation on the matter. Their documentation states that:
Accessories can be physically connected to the device through the 30-pin dock connector or wirelessly using Bluetooth.
This still will not enable you to play games between devices that aren't iPhoneOS, as you need the iPhoneOS, and it's GameKit framework on both ends. If you are interested in setting such a thing up, you will have to look into managing it manually.
I would strongly advise against using bluetooth, as it's buggy, slow, and has a short range. Peer to peer Wifi or LAN play will be your best bets. I suggest looking into using Bonjour of you're using LAN play. Here are two tutorials (one, two) on using Bonjour. Happy gaming!
the last i heard, bluetooth is 'crippled' on the iphone meaning you can only transfer data via bluetooth to another device with an Apple approved bluetooth chip in it. check out the apple docs for developing 'accessories'.
