MediaTek platform eases dev't of Wi-Fi enabled IoT devices

MediaTek introduced the LinkIt Connect 7681 development platform as part of the MediaTek Labs initiative. Based on the company's MT7681 Wi-Fi System on Chip (SoC), the platform provides developers and makers with the tools needed to create simple Wi-Fi-enabled Internet of Things (IoT) devices that can be controlled from smartphones or the Internet.

"The world is rapidly moving towards connecting every imaginable device in the home, yet developers often have to spend too much effort on making their products Wi-Fi enabled," said Marc Naddell, VP, MediaTek Labs. "The MediaTek LinkIt Connect 7681 platform simplifies and accelerates this process so that developers can focus on making innovative home IoT products, whatever their skill level."

To enable developers to take advantage of the features of the MT7681 SoC, the new platform provides a Software Development Kit (SDK) for Microsoft Windows and Ubuntu Linux, a Hardware Development Kit (HDK) co-designed with Seeed Studio and related documentation. The SDK enables developers to compile and upload the firmware needed to control an IoT device in response to instructions received wirelessly, while the HDK delivers the LinkIt Connect 7681 development board.

The board includes the LinkIt Connect 7681 module, micro-USB port and pins for each of the I/O interfaces of the MT7681 chipset. The LinkIt Connect 7681 module (co-designed with AcSiP) is available to order separately and is designed to easily mount on a PCB as part of production versions of the IoT device.

Connectivity on the MT7681 is achieved using Wi-Fi, in either Wi-Fi station or access point (AP) mode. In Wi-Fi station mode, MT7681 connects to a wireless AP and can then communicate with web services or cloud servers, for uses such as controlling the heating in a home from a home automation website. In AP mode, the MT7681 chip lets other wireless devices connect directly to it, allowing, for example, a smartphone app to control a smart plug or light bulb in the home.

MediaTek Labs was launched in September 2014 and continues to provide developers, makers and service providers with SDKs, HDKs and documentation, as well as technical and business support. MediaTek LinkIt Connect 7681 is the second development platform in the MediaTek LinkIt portfolio of developer offerings for IoT and wearables.
