Check iPod Touch hardware performance programatically - objective-c

I stuck with a weird problem . I am having two iPod touch devices for testing purpose both are having same platform i.e. iPod touch 4G but different performance in terms of speed.
To check device platform i have used following link : Determine device (iPhone, iPod Touch) with iPhone SDK
My app is working perfectly for both the iPod touch but for one iPod touch it is crashing because of device performance issue. I want to distinguish between iPod Touch device of same platform but different performance so that I can make changes to my app as per device performance.
Is there any way to check iPod Touch device
hardware performance programatically.
Thanking you in advance..

Core bluetooth in WatchKit in apple watch?

I want my watch app to be identified by my paired iPhone.I am using CoreBluetooth Framework to implement this. I am transmitting bluetooth signals from my watch app and trying to receive the signal in my iPhone app. I am using the same concept as apple has shown in its sample code (https://developer.apple.com/library/ios/samplecode/BTLE_Transfer/Introduction/Intro.html#//apple_ref/doc/uid/DTS40012927) , the only difference is that my transmitter is the watch app.
Issue
I am unable to detect watch app in my iPhone. I have made sure that all of my hardwares are configured properly and I am configuring the Core bluetooth delegate methods properly. I also suspect if this method will be feasible with iPhone and apple watch.
All suggestions are appreciated. Thanks in advance
This is not possible because your WatchKit app runs as an extension on your iPhone and therefore all Core Bluetooth bluetooth signals are sent from the iPhone itself to itself.
Access to Core Bluetooth on Apple Watch lets your apps bypass the phone and connect directly with the Bluetooth in Apple Watch. Access Core Bluetooth to connect directly with accessories. And with Apple Watch Series 3, your apps can take advantage of built-in cellular and altimeter capabilities.
Please note, since watchOS 6 it's possible to use CoreBluetooth on watchOS.
Check for more informations this link "Creating Independent watchOS Apps"
Be aware there are still some limitations using CoreBluetooth in watchOS for example:
The minimum connection interval is 30ms instead of 15ms (for iOS devices).
The Apple watch can only operate as a central device.
The Apple watch can only be connected to two peripherals at one Time
The peripheral gets disconnected when the app goes into the background.
Maybe this will change when watchOS 7 is out.

need help for bluetooth framework on mac osx

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?
linkos
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.

How can I transfer data via bluetooth from an iOS device to a Mac?

I want to be able to transfer basic information (strings and such) from an iOS device to a Mac, and vice versa, via apps installed on each device. I've been trying to get bluetooth on the iOS device, but it seems to only want to connect to other iOS devices.
Bluetooth access on the ios is very limited. As a matter of fact you can only access it through the GameKit.
http://developer.apple.com/library/ios/#DOCUMENTATION/NetworkingInternet/Conceptual/GameKit_Guide/Introduction/Introduction.html
So if you want to share information with a Mac you would have to make the mac appear as an iOS device. I however ignore how you could do this.
