Wireless software licensor Packetcraft, Inc., has announced that its Packetcraft Controller software has achieved Bluetooth 5.3 qualification, including the first qualification of new Bluetooth 5.3 link layer technical features. Packetcraft has also announced the availability of Packetcraft LC3, a highly optimized and efficient LC3 codec for Bluetooth LE Audio.
Bluetooth® Core Specification version 5.3 is the most recent core protocol specification released by the Bluetooth Special Interest Group (SIG). The 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 hearables products like wireless earbuds and hearing aids.
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.
The latest audio codec offering, the LC3, has already achieved Bluetooth qualification and has already been commercially licensed to a tier 1 consumer electronics maker. The 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.
