Just would like to know: is there any way to programmatically determine if an iPhone is connected (via USB or Bluetooth) to the CarPlay system? Thanks in advance.
CarPlay navigation apps can use the CPApplicationDelegate to find out whether they're connected or not. CarPlay audio apps do not need to do that.

Remote access of an iOS app

I want to get remote access of my iOS app running on one iPad in another iPad. Is there a way in iOS SDK to achieve this?
Any help would be highly appreciated. Thanks
No, there's not. You can mirror the screen to another device using AirPlay, but there is no way to "drive" the device remotely. (There's an app called "Reflector" that lets you mirror you iOS device onto your Mac, but it's view only.)

HID client implement in iOS

Can we used our iPhone as a HID client in iOS by using Bluetooth? We want to make HID communication with a Bluetooth Dongle. Our iPhone will send keys to dongle like a Keyboard, mouse , joystick etc.
The same we can done between a keyboard and a Dongle. But How it will possible when we are using ios device and dongle?
Please help to clarify my doubts If I am wrong anywhere.
Thanks in advance!!
iOS only provides HID Host, but not HID Peripheral. You may be able to capture the keypresses in an iOS application, and send the equivalent data (ASCII or HID frames) via Bluetooth Low Energy. A custom application on the dongle/device will be required to receive the data and convert/execute to HID if desired.

Bluetooth connection in iOS

Is it possible to programatically pair an iOS device with a Bluetooth device?

Thanks for any pointers.
