Windows 8.1 Seamless integration of new device protocol APIs

In Microsoft's official Windows APP Builder Blog, Microsoft has shown an "exciting" improvement in Windows 8.1. Thanks to support for several innovative device protocol APIs, Windows 8.1 offers the potential to access a large number of devices. "One of the most exciting improvements," says Microsoft, "is that Windows 8.1 previews release valves that access huge amounts of equipment." Although Windows 8 already supports certain devices such as printing, sensors, geolocation, and so on, access to devices is limited to those specialized applications. In Windows 8.1, this has changed dramatically.

"We support a number of innovative apis--such as point of Sale (POS), 3D printing and scanning, through the device Protocol API, to access the other huge amount of equipment opened the gate."

The Device Protocol API (Device Protocol APIs) is a new feature in Windows 8.1 that allows application developers to create an application, as well as USB, HID, Bluetooth, Bluetooth smart, and WiFi Direct and other protocols to communicate. and the working principle behind the scenes is a simple process.

The developer needs to use metadata to identify a device and open a communication channel for the device. Opening a channel means that the user grants a single access permission, and then the application can communicate with the device.

Microsoft said: "Windows 8.1 Preview provides a wealth of applications and equipment for communication support." By seamlessly integrating standard devices such as printers and sensors and even custom devices into your applications, users can enjoy fast and fluid device interactions.
