Question1.
IOBluetooth can support connection both ways via LE or classic. However it only supports macOs. CoreBluetooth supports only up to LE along with IOS.
As far as I know, in order for me to connect my bluetooth connection within IOs device, I must use CoreBluetooth frameworks. Am I correct?
Question2.
CoreBluetooth frameworks can connect Windows10 labtop with bluetooth connection?
Your question is a bit vague. I assume you just want to have a way to exchange some data between an iOS app and your Windows 10 desktop.
Yes, you are correct. Usage of Bluetooth Classic in any of your iOS apps requires Apple MFI Membership and only makes sense if you have your own product. If you are not a member of the MFI program then you are left with CoreBluetooth (BLE). Please note, that BLE is significantly slower than Bluetooth Classic so it only makes sense for applications that require transmission of small data packets (expect around 4kB/s max).
Yes, as long as your Windows 10 device supports BLE. If you want to use any of the SIG adopted Profiles such as HID over Gatt you should be able to connect without any additional software. Otherwise you need to implement your own profile. If you want to know more about your options, I suggest you have a look at the CoreBluetooth documentation and/or get a copy of Getting Started with Bluetooth Low Energy which is a comprehensive read on the topic.

For testing purposes I need to power off a USB device from my computer programmatically. The microprocessor in the USB device is ARM Cortex M4.
I have tried using Devcon, although the device was disabled, power was still provided to the device.
I have also tried to disable the USB root hubs ,that also didn't work.
I have read some other posts indicating that a SSR could be used, this option is not desired. I would rather choose the software solution(if there is one of course).
Some other answers have indicated that this is an OS issue, and some others a chip-set architecture issue.
So my question is what options are there available. And also is this purely something dependent on the computer side or do we need to implement something on the USB device side as well.
Thank you in advance.
I'm wondering if Firefox OS handsets could be useful as a platform for DIY hardware projects. Hence my question: Can Firefox OS apps read out USB pins?
Compared with Arduino it would be obviously be overpowered, but the handsets have decent battery life and all connection stuff like wifi already built in.
Not right now, but we are working on USB support as part of the WebAPI work. The bug to monitor is here: https://bugzilla.mozilla.org/show_bug.cgi?id=737153
I need to know few things about IOBlueTooth framework for MAC:
Does this framework support BTLE?
What different does it has from iOS framework CoreBlueTooth?
To support BTLE on MAC OSX, do we need both IOBlueTooth & CoreBlueTooth framworks? Please share link for some sample app, if any?
Also, please point me to some good documentation or WWDC videos for IOBlueTooth framework.
1.) Yes..assuming you have a mac that supports BLE (airs, minis, and newest macbook pro's i believe)
2.) The IOBluetooth framework contains C and Objective-c api's to connect to nearby Bluetooth devices (not only BLE devices). So yes, it contains the CoreBluetooth.framework, but the IOBluetooth framework allows you to interact with Bluetooth devices supporting other protocols as well.
3.) You need to import the IOBluetooth.framework since CoreBluetooth.framework is embedded inside it, but that's all you need to do with it.
Check out the Heart Rate Monitor sample code.
Has anybody found the specifications for the USB protocol used by the Xbox controllers? All I can find is the API documentation of Microsoft's implementation (Xinput). I'm trying to write a driver for OS X so Xinput controllers will appear as normal HID devices. Without the specs I'm pretty at a loss...
There is a linux driver here https://github.com/Grumbel/xboxdrv for the XBox that should get you a long way to getting it working on Mac. I don't think the spec is available legally without signing an NDA and paying Microsoft money.
i'm an iOs developer and I actually need to make a mac application that use bluetooth framework to connect to another device (not iOS device).
I'm actually showing a modal view showing the connected bluetooth device with IOBluetoothDeviceSelectorController and I get the user choice with [modal getResults] but I don't know how to initiate the connection with the selected device and I can't find a simple way to do it on the mac dev library.
is anyone know a tutorial or sample code that could help me advance in my project?

The Mac Developer Library has two sample Bluetooth projects; connecting to a health thermometer and connecting to a heart rate monitor. There is also video available of the Advanced Core Bluetooth WWDC 2012 session.
