Based on Qualcomm's QCC5100-series Bluetooth audio chips, the reference design includes virtually all the key hardware and software required for manufacturers to help them develop Bluetooth headsets. In addition to support for Alexa, the solution also supports ultra-low power consumption for extended playback time and battery life, as well as Qualcomm cVc noise reduction technology. Manufacturers can also add support for active noise cancellation and Qualcomm aptX HD high-resolution wireless audio.
The Qualcomm Smart Headset Development Kit is the first Bluetooth Smart Headset reference design built with support for the Alexa Mobile Accessory Kit, a protocol that runs over Bluetooth and is designed to allow users to connect Bluetooth-enabled audio devices with Alexa via the Alexa app. This means device makers no longer need to oversee the bulk of coding for their Alexa integration or to add any communication hardware beyond Bluetooth.
The Smart Headset reference design is addressing design challenges associated with developing small form factor wireless headsets, including audio quality, RF and antenna design, power consumption and PCB layout.
The QCC5100-series SoC features a dedicated application processor sub-system, dual DSP architecture and audio development kit software. The SoC family is also engineered to support concurrent software operation, meaning that users can transition between functions such as listening to music, making calls, running biometric sensors and using voice services.
The Qualcomm Smart Headset reference design with Alexa is available now.
