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'.

I have done some research on core bluetooth framework. Successfully setup discovery of peripheral of other iPhone, connect, discovered services and characteristics and write some values. All went well. Surprisingly come to know there is apple MIFI program (need to research on it).
In excitement I ordered iPhoneSE, HC-05 bluetooth module, Arduino Builder's Kit R2 with original Arduino UNO. It took some days/wasted in shipment and decent amount and now it's not working.
I write proper set up/initialization for peripheral and central classes, adopted delegates and I think it's all correct. However I am not able to connect to HC-05 bluetooth module.
Observations:
On a Android device i turned on bluetooth in device settings, HC-05
was able to be discovered, enter 0000/1234 (password as per
documentation). And yes i was able to connect it. It means HC-05 is
not malfunctioning.
On a iPhoneSE iOS v11.0, Setting -> turn on bluetooth. But HC-05 is
not discoverable.
I simply want to be successfully discover and connect to HC-05 module using BLE technology. Then with delegate methods look up services/characteristics and then try to on/off led.
I can provide more info and background if needed.
I need some help and direction so that I can purchase the correct bluetooth module which connect to iPhone, and I am sure I can do it.
Thanks.
To answer above question-
HC-05 will not connect iPhone. Because HC_05 is not bluetooth low energy.
I have used AT-09 from amazon.
I have written complete article how I achieved it here, and challanges I faced with solution.
The HC-05 isn't compatible with iOS.
This is because Apple uses MFi Licensing Program and HC-05 is not licensed.
To get things working go for a module supporting minimal BT Version V4.0 BLE. Even better, BT Version: V4.2 BLE & V5.0 (better range and larger packet-size), if iOS (v11.0) supports it.
I am not going to recommend a specific model, that's what Google is for.
Apple devices under the MFi licensing scheme only support limited profiles.
HC-05 is based on Bluetooth 2.0. What will work for Apple mobile devices (iPhone, iPad) will be those modules that utilise Bluetooth 4.0 or Bluetooth Low Energy (BLE).
I'm guessing bluetooth.
What are the transfer speeds?
It would have to work on iPhones which are not jailbroken, although I'm still curious about how it could work better on jailbroken ones.
The GameKit GKSession class supports connecting to nearby instances of the same app using both Wi-Fi and Bluetooth. The choice of transport is completely automatic and hidden by the API. So you could use that to transfer data between nearby devices. I don't know what the transfer speed is like though. Probably not very good.
I guess, via "Bump Technology".
Has anybody succeeded in developing a bluetooth application on the iPhone that prints to a Bluetooth printer?
I have been investigating the feasibility of developing an iPhone application that could print to a Bluetooth-enabled printer. I've gone through the most of the postings in this thread and was confused by the mail exchanges.
As per my analysis:
Gamekit - can be used for bluetooth connectivity between iPhones and IPods ONLY
Bonjour - can be used for wi-fi connectivity between iPhones/IPods and bonjour-enabled printer
We can use an external accessory to connect to a third party Bluetooth-enabled printer provided the 3rd-party printer complies with the necessary regulations from Apple (registering for either “Made for iPod”/ “Works with iPhone”, and also customizing their printer with specific hardware/software, etc.)
Could someone please share their experiences?
You want their external accessory framework. Not GameKit. Happy coding!
The External Accessory framework provides support for communicating with external hardware connected to an iPhone OS–based device through the 30-pin dock connector or wirelessly using Bluetooth.
(This is exactly what you were looking for)
To detect and connect to external devices ExternalAccessoryFramework should be used.Me too developing an application for connecting iphone to other hardware devices via bluetooth .A'm facing the problem with the protocol.The protocol should be the hardware supported ones and the protocol should be given in the info plist file..
Happy coding.
You can want to try this Bluetooth printer, which is Apple MFI approved

I would bet that you would need to use Bonjour and Wi-Fi for this application. The bluetooth hardware is restricted to gameplay from what I've seen.
well i have sucsessfully accomplished bt printing on a customers I-phone both devices have to be in discovery mode to do so and then the combination wireless and bt will allow only photo printing though otherwise you will need an app
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.

i'm participating in the iPhone Developer Program and i have access to the iPhone 3.0 firmware and SDK.
one of the new features of the iPhone 3.0 -- is ability to use Bluetooth, but i can't find any documentation about it.
can someone point me please -- where is it?
The only way of using bluetooth directly is if you join the Made for iPod / Works With iPhone program and integrate the Apple authentication chip into your custom device. Once you've done that, you can use the ExternalAccessory framework which exposes a low-level IO stream API to the device.
Frameworks like Core Audio will let you play and record music via bluetooth headsets and the Gamekit framework will let you discover and talk to other devices via bluetooth, but the fact that it's bluetooth is not exposed to the developer at all.
Look at the GameKit API - it provides simple high level access to BlueTooth connections between devices (built on Apple's Bonjour discovery service).
If I recall correctly, you aren't allowed direct access to the Bluetooth, but rather, you are able to use certain API calls that will search for nearby devices. However, I'm not a developer currently, so I can't point you at any documentation. Perhaps someone else can back me up with a bit more information.
My iphone 3G & 4 will connect to my Sony BT1500 car head unit which was made well before iPhone existed (i.e it's not iPod signed).
