Dialog Semiconductor plc, a provider of highly integrated power management, AC/DC power conversion, solid state lighting (SSL) and Bluetooth low energy (LE) technology, has announced the availability of its latest Apple HomeKit development kit, to reduce the time-to-market and increase functionality of smart home and other Internet of Things (IoT) devices.
With the recent introduction of iOS 10, Apple HomeKit is now an integral part of iOS, including its dedicated app that creates an enhanced user experience. The Apple Home app is compatible not just with iPhone, but is also optimised for iPad and the Apple Watch running watchOS 3. With the app, an Apple TV or iPad can easily be turned into a smart home hub, enabling home control from anywhere.
Dialog’s second-generation kit supports all current HomeKit Accessory Profiles within Apple’s updated IoT platform. The kit itself is built on Dialog’s DA14681 System-on-Chip (SoC), the most integrated single chip solution that is purpose-built for IoT development, providing connectivity to a variety of battery-powered devices. It is the first SoC on the market with dedicated hardware acceleration for HomeKit security operations which ensures end-to-end application encryption, safeguarding personal information in transit.
“Our new development kit lowers the barriers for smart home device development,” said Sean McGrath, SVP and GM Connectivity, Automotive and Industrial Business Group. “Beyond the simplicity of the highly integrated connectivity SoC at the heart of the kit, its fastest response times create the best possible user experience for end devices, with initial pairing taking less than 2.8 seconds and responding faster than 250 ms whenever an iOS device issues a command. This creates an instant response whenever a user interacts with a HomeKit-powered light, door lock, smoke detector or other accessory.”
The DA14681 supports Bluetooth 4.2 to provide seamless connectivity, and smartly balances power efficiency and performance, with an ARM Cortex M0 processor, expandable flash memory, a Power Management Unit (PMU) for sensors and motors, and built-in charger that supports a USB interface.
Its integrated topology streamlines development, minimises BOM cost and enables the kit to consume less than five µA on standby. The development kit maximises application space and flexibility, using a mere 170 kB of Flash memory and provides 64 kB of RAM for apps to utilise, even allowing user defined profiles to further customise applications on top of pre-configured HomeKit profiles.
To give developers all of the tools they need to create next-gen IoT applications, the DA14681 development kit consists of the HomeKit SDK, Basic and Pro versions of the kit, and a flexible add-on board to interface with the separately available MFi chip.
