Atmel enables low-power IoT WiFi connectivity via social platform

November 17, 2015 // By Graham Prophet
Atmel has disclosed a path to ultra-low power Wi-Fi connectivity to the WeChat IoT platform, enabling secure cloud access for IoT applications.

Using the Atmel | SMART SAM W25 SmartConnect module, the WeChat IoT platform supports the latest Airkiss 2.0 protocol for Wi-Fi provisioning and service discovery, allowing developers of connected devices to seamlessly connect to the cloud.

Atmel is collaborating with WeChat, the social communication platform, on their IoT Platform with the SAM W25 module integrating a secure ATECC508 CryptoAuthentication, for cloud access targeting IoT applications. WeChat IoT Platform delivers cloud services for seamless accessibility to the Internet (“cloud”) ensuring every ‘thing’ is smartly connected and supports the recently launched Airkiss 2.0 protocol for Wi-Fi provisioning and service discovery.

The platform, which is currently available in China, delivers a complete edge node-to-cloud solution from a single vendor for IoT developers to build leading-edge applications for connected devices. Consumers can access information from their IoT devices via the Weixin app, WeChat’s sister product targeting users in China, on mobile devices. Developers can build IoT devices using the SAM W25 development board for seamless and secure connectivity on the WeChat IoT Platform, supporting the Airkiss 2.0 protocol for wireless provisioning. Consumers can then instantly connect to their IoT devices via the Weixin app.

The SAM W25 module is part of the Atmel SmartConnect family of wireless devices, and includes Atmel’s 2.4GHz IEEE 802.11 b/g/n Wi-Fi WINC1500, along with an Atmel | SMART SAM D21 ARM Cortex M0+-based MCU and Atmel’s ATECC108A optimised CryptoAuthentication engine with ultra-secure hardware-based key storage for secure connectivity. The module is ready-to-use and FCC certified delivering a plug-and-play solution.

Pierre Roux, Director of Wireless Solutions at Atmel comments, “Weixin is one of the leading providers of IoT cloud services and a fully integrated provider with a host of capabilities ranging from simple texting to payment, portal and more. IoT developers and manufacturers using the Atmel SmartConnect SAM W25 evaluation board on the Weixin IoT Platform will have access to one of the largest user communities currently available for cloud services. Our collaboration with Weixin is just the beginning of a long-term collaboration as it is transitioning to IoT.”
