OEMs can now implement one touch setup processes for consumers, increasing user satisfaction. Trillbit’s Data-over-Sound technology brings an unprecedented level of security and user experience in authentication use cases across industries, especially for smart home connected devices and in online access authentication. Trillbit’s TrillConnect SDK, based on Trillbit’s ‘Data over Sound’ technology, is integrated efficiently into the Knowles IA61x SmartMic, paving the way for highly secure and hassle-free onboarding and setup solutions.
"A challenging setup experience is one of the top reasons consumers return their smart home products and one of the largest barriers to boost consumer adoption of IoT devices," says Mehul Kochar, Sr. Director Business Development, Audio Solutions at Knowles. "The addition of Trillbit’s TrillConnect SDK to Knowles SmartMic DSP makes it easy for OEMs to ensure their consumers have the best and the simplest setup process, in turn ensuring consumer satisfaction and lower return rates."
Conventional Wi-Fi setup involves multiple steps and can be confusing for non-technical users which have no idea what IoT even means. Smart home devices, such as speakers, typically do not have a user interface (aka headless) and offer little visibility to the user regarding errors during setup. When a user needs to repeat the setup process multiple times, such as for failed initial setups, network changes, or when provisioning multiple devices, a complex initial process is compounded and can frustrate the user. This leads to poor "out-of-box" first impressions and can be the cause of costly customer service calls and product returns.
Implementing secure authentication is a major hurdle for headless consumer connected devices. The Knowles IA61x family of SmartMic Voice Wake Audio Processors with Trillbit’s ‘Data Over Sound’ technology easily integrates into any smart home device to streamline network provisioning. The Trillbit TrillConnect SDK allows for the efficient transfer of encrypted digital data that triggers the gadget to "wake up" and enter the setup phase.
TrillConnect transfers a user's Wi-Fi credential between the user's phone and a new device without the need for Bluetooth pairing or Soft Access Point connection. After unboxing the new device and putting it in setup mode, the user can go to the vendor’s app to pass on the credential. If he is using the app for the first time, then they only need to input the Wi-Fi SSID and password and click to connect. Trillbit’s SDK, embedded in the app, encodes and encrypts this data on inaudible sound waves and transfers it to the new device automatically.
TrillConnect encodes any data into a series of near-ultrasound frequencies. This encoded data gets played by a sending device by their speaker in form of Trill tones, over the air, to a receiving device where it is received by a microphone and decoded by the Trillbit SDK. A Knowles SmartMic makes the most efficient and cost-effective listening device that is capable of decoding the Trill tones into usable data. An OEM can customize their smartphone app to authenticate a new connected device by integrating a Knowles SmartMic enabled with Trillbit’s decoder algorithm and securely send sensitive provisioning data with minimum consumer involvement.
“We are excited to collaborate with Knowles, an IoT industry leader, to solve this critical pain point for OEMs," says Bhaskar Deo, CEO at Trillbit. "Trillbit’s ‘Data Over Sound’ is a new communication channel that bridges the gap to solving these challenges with a frictionless user experience. ‘TrillConnect’ vastly simplifies the commissioning of headless devices: one-touch setup with no pairing or configuration, no additional hardware requirements, and the ability to set up multiple devices at once. Manufacturers can provide a setup solution that is preferred by users and ultimately a better product experience."
The IA610 and IA611 include an "always-on" Acoustic Processor featuring Voice Wake and Voice ID keyword detector, a pre-roll buffer, and Knowles’ proven acoustic SiSonic MEMS technology in a single, miniature, top-port (IA611) or bottom-port (IA610) package. The IA61x family supports the most relevant audio and data interfaces. Its integrated programmable DSP with 248 KBytes of RAM is available for developers and third-party algorithms, enabling unlimited creativity. The solution pushes the system performance to ultra-low power with its custom core design and accelerates times to market with its unique combination of hardware, software, and firmware.
