I know that there are a lot of restrictions on bluetooth when it comes to iOS. I wanted some more information on Bluetooth Low Energy (LE) and the CoreBluetooth Framework apple provides from iOS 5.0 and greater.
Can i connect ANY Bluetooth LE device to an iOS device using the Core Bluetooth Framework?
Is there any Bluetooth LE device in production,that comes with a three axis accelerometer and a gyro that i could use like a Human Interface device?
Sagar, Maybe you can explain more about what you want to do.
Any BT4.0 LE device can connect and communicate with a iOS app using the CoreBluetooth Framework.
The CC2540 dev kit does contain a fob that has accelerometer, it does not have a gyro.
The USB dongle that comes with the kit is for communicating with the fob from a PC/Mac, you do not need it for communicating with the iOS device.

Can I connect iPhone and bluetooth 2.1 device and work with them via Core Bluetooth? I just need to send and receive some NSString data from/to iPhone.
No, Core Bluetooth only supports Bluetooth Low Energy/Bluetooth 4.0 devices. You can only connect to Bluetooth 2.1 devices via the MFI program and the external accessory framework.
The only exception is "standard" devices such as keyboards and audio devices (hands free etc). However in these cases you can't access any underlying Bluetooth information - you can simply send audio or receive keyboard input.
The only way your own device talk to your iPhone is Bluetooth Low energy if you can not apply MFI program(Most of cases). You need some Bluetooth Low Energy DevKit like TI2540/TI2541 or Nordic or Dialog, they are equipped with rich interface like UART, button, LED and simple speaker. The cheapest chip on market is TI2540(also oldest), but it is MCS51 based core MCU, not very friendly. Other arm based dev kits are more friendly.
The core bluetooth in iOS is not very easy to use, I will recommend you try https://github.com/kickingvegas/YmsCoreBluetooth , it is awesome.
Not possible to work with 2.1 bluetooth in core bluetooth library.
Core bluetooth support Bluetooth Low Energy(BLE) support.Ex. Bluetooth 4 or greater version of BLE devices.
Bluetooth 2.1 is classic bluetooth device.
I have a medical device which is Bluetooth enabled with version 2.1+EDR.
I want to integrate the device inside my application. I am targeting mainly the iOS devices with BLE/Bluetooth 4.0 .
Any idea the latest iOS devices will be compatible with mentioned medical device. IF so how will be the approach.(means I can use Corebluetooth ,EAAccessory framework or I have enroll the MFi Program).
If the device is Bluetooth 4/Bluetooh Low Energy (also known as Bluetooth Smart) the you can use Core bluetooth. If it is Bluetooth 2.1 then you need to go through the MFI program and embed an Apple chip in your device I order to identify it to iOS and use the external accessory framework
I am using CoreBluetooth framework for first time in my Objective-c code.
My iPhone version is iPhone-3GS.
When I run my code, I get output as "The platform or hardware does not support Bluetooth low energy".
I saw 3GS specifications and got to know that it supports v2.1 with A2DP. But what I expected is whether Bluetooth is powered ON or powered OFF.
How can I get Bluetooth status through objective-c code using CoreBluetooth framework?
How to get Bluetooth status through Objective-c ?
Can anyone share a link or tutorial on this?
CoreBluetooth is the API meant for Bluetooth LE in iOS5+.
It does not support "normal" Bluetooth or any "normal" Bluetooth profiles.
As far as I remember, the first iOS device supporting Bluetooth LE was the iPhone 4S - your 3GS just does not have the correct hardware.
Bluetooth LE is part of Bluetooth 4.0 and meant for reading sensors and alike...

You will definitely not make it work using your 3GS, sorry.
We are making MFi hardware and an iOS app. We will want to have the BT device notify our app even if we are not running periodically when certain events happen.
I know the CoreBluetooth API is the one to use, but can't tell for sure if that API only works with BT Low Energy devices or if it will also work with regular (MFi of course) BT 2.1 and higher devices.
So my question is: Does the CoreBluetooth API only work with Bluetooth Low Energy devices or will it also work with 2.1 devices?
Core Bluetooth is designed specifically for Bluetooth LE, a.k.a. BLE, Bluetooth 4.0 and Smart Bluetooth.
Core Bluetooth does not work with the older, classic Bluetooth devices. Those require special APIs and hardware available through Apple's MFi program.
I have a Bluetooth 4.0 Low Energy board. I want to develop a iOS app for the iPhone 4S that receives and sends data from the board.
What framework do I need to reseach/find-documentation-for? Will the Core Bluetooth framework in the iOS SDK work? Will I need to use the GameKit framework?
I just started looking into iOS development a few days ago so I'm trying to navigate through this maze! Thanks!
Core Bluetooth which is part of the iOS5 SDK is all that you need.
You do not need Gamekit or MFi to develop Bluetooth low energy apps.
You will also need a device that supports Bluetooth Low Energy 4.0 (iPhone 4S or the new iPad) to test your app.
Frameworks which are used for discovering the device via Bluetooth are:
CoreBluetooth framework for discovering BLE devices
GameKit Framework for discovering other type of devices.
EAaccessory framework which can be used to interact with paired Bluetooth devices or devices connected through wired, Apple Connector at the base of the device.
Apple MFi Program means you will have a device that is designed to be compatible with iOS devices (meaning, the manufacturer must be a member of the Apple MFi program) and the device manufacturer most provide a protocol that you must add to your applications info.plist file.
Focus on Core Blutooth. Gamekit will only be useful with other iOS devices.
