GainSpan Application Development Kit Speeds Wi-Fi Smartplug Design

With the ADK, users can control electrical loads and accurately measure power consumption of any household electrical appliance either locally using a PC or smartphone, or from the cloud via an infrastructure network.

Voltage, current, frequency, instantaneous power, energy and power factor are measured or calculated and displayed on the mobile or web application.

The Smartplug ADK includes smart plug hardware, complete hardware design package and software suite with reference source code for the smart plug embedded application and iOS and Android based mobile applications. A Smartplug Application Evaluation Kit (AEK) is also available that provides a binary version of the software and can be used to evaluate and demonstrate smart plug operation.

The Smartplug hardware includes a standard socket, single-phase 100-245V, 10A smart plug which uses a GainSpan GS1011M Wi-Fi module interfaced with a power measurement IC. The embedded software runs on the GainSpan Wi-Fi module and offers complete Wi-Fi functionality including the entire networking stack and services, wireless security and provisioning software. It supports mDNS/DNS-SD based device and service discovery that allows users to automatically discover and connect to the embedded Smartplug profile. In addition, the Smartplug application includes provisioning software that allows configuration of the Wi-Fi module in Limited AP or Client modes, and allows over-the-air firmware upgrades. It also supports factory restore of the embedded firmware and WPS for ease of setup.

The Smartplug ADK provides hardware and software building blocks that provide a starting point for product development while allowing the developer to add application software and services, and customize the end product’s user interface. With the reference source code included in the kit, customers can rapidly build custom features suited to their end applications.

“With the growth in ‘green’ initiatives, we’ve had a lot of interest from customers looking for a simple way to develop new wireless smart energy applications and our new ADK allows them to do just that,” said Bernard Aboussouan, vice president of marketing at GainSpan. “This is one of a series of ADKs that we’re developing featuring complete end applications, and all are aimed at speeding time-to-market for customers.”
