Bluetooth Core Specification version 5.3 is the most recent core protocol specification released by the Bluetooth Special Interest Group (SIG). Packetcraft Controller implements multiple new Bluetooth 5.3 link layer enhancements, including Connection Subrating, an important power savings feature that also enhances the user experience of products like wireless earbuds and remote controls.
LE Audio is the next generation of lower power, higher quality Bluetooth audio. It supports the same audio use cases as Classic Audio, plus advanced products like Bluetooth LE hearing aids, and new use cases like Audio Sharing via broadcast. LE Audio introduces a new codec, called LC3, that dramatically improves audio quality, reduces power, and improves latency compared to Classic Audio.
Packetcraft’s new audio codec offering, Packetcraft LC3, has already achieved Bluetooth qualification and has already been commercially licensed to a tier 1 consumer electronics maker. Packetcraft LC3 is highly optimized for the Arm Cortex-M4 and Cortex-M33 processors. It is capable of supporting demanding audio use cases running multiple codec instances on a single processor, without requiring a dedicated DSP.
“With today’s announcement of Packetcraft LC3 and Packetcraft Controller for Bluetooth 5.3, Packetcraft differentiates itself as a single-source Bluetooth software supplier, enabling companies to make compatible and interoperable LE Audio products such as hearing aids, wireless microphones, and broadcast headsets,” says John Yi, CEO of Packetcraft. “Our licensees have already begun developing this next generation of Bluetooth audio products.”
The comprehensive software solution for LE Audio, now available from the San Diego-based company, consists of the Packetcraft Controller Bluetooth 5.3 link layer with isochronous channels, Packetcraft Host, the company’s Bluetooth 5.3 host stack with profiles for LE Audio, and Packetcraft LC3 codec for LE Audio.
Packetcraft comprehensive protocol stack solution for Bluetooth LE Audio is supported on the Nordic Semiconductor nRF5340 wireless System-on-Chip (SoC). This combination is ready to meet the needs of ultra-low power audio applications, such as wireless stereo earbuds and hearing aids. Packetcraft's software release for the nRF5340 is available now under commercial license to enterprise customers.
