The ability to monitor and control their Bluetooth sensors remotely

Now, with Bluetooth Secure Gateway Toolkit, developers have access to components and simple initial set-up, in-depth and hands-on labs, and enhanced security components to create an Internet gateway that gives people the ability to monitor and control their Bluetooth sensors remotely. 

Developers can now expand IoT functionality in their products and leverage industry leading, government-grade security features introduced in Bluetooth 4.2. 

I can also recall that, devices can now connect directly with this gateway via a secure connection without the need for a smartphone or tablet to serve as the go-between.
