Qualcomm's low power WiFi platform for IoT gets development support

One year after the launch, QCA4002, a low power single chip Wi-Fi solution for connecting multiple number of devices to Internet, finds increasing adoption by IOT companies.

Arcturus Networks has developed a wireless IOT solution using this Qualcomm QCA4002, a low-power and also low-cost chip. Arcturus has also used Freescale Kinetis K60 microcontroller running Arcturus Mbarx-M2M firmware and additional VoIP or audio distribution capability.

Arcturus' M2M capable system can be operated and managed via a TCP/IP socket connection or UART interface. Its solution supports a “peripheral on-boarding”, Where it is possible to address connected sensors or peripheral devices remotely using the Mbarx-M2M communication interface.

The demo solution can be used in combination with Arcturus voice firmware to make specialized wireless IoT devices including audio applications such as push-to-call intercoms, door phones, voice enabled door bells, wireless VoIP handsets, mobile healthcare pendants, PA speakers and announcement systems.

The QCA4002 and QCA4004 targets home appliances applications such as washing machines, air-conditioners, and hot water readers which can be connected to Internet. In fact this chipset also can be used for home lighting, security and automation system. The speciality of QCA4004 is, it can operate in a pure hostless mode of operation.

QCA4002/4004 support an open source software called AllJoyn software framework. AllJoyn software framework is developed by QUALCOMM which enables interoperability among connected products and software applications across manufacturers to create kind of dynamic Proximity networks. AllJoyn software framework which provides basic building blocks for maximum flexibility and includes a set of services that by design are very simple and addresses near universal requirements for users to interact with nearby things such as on boarding notifications, audio streaming and control.

The real time operating system company Micrium,has made available of its first Micrium TCP-IP driver for the QCA4002.

The Micrium driver for the QCA4002 (GT202 module) runs on hardware with an SPI controller interface. Micrium tested the driver with a Renesas RX63N and with a Freescale Kinetis K70. The Netcom GT202 module, which comes pre-certified and packaged, is available from Arrow Electronics.

If you're looking for device drivers Intelligraphics offers off the shelf Wi-Fi device drivers for the Qualcomm Atheros QCA4002 and QCA4004 on multiple microprocessors and operating systems.
