Packetcraft has announced that its comprehensive protocol stack for Bluetooth LE Audio is supported on the Nordic Semiconductor nRF5340 wireless System-on-Chip (SoC). This combination of Packetcraft's world-leading LE Audio software with Nordic's most advanced wireless SoC is ready to meet the needs of ultra-low power audio applications, such as wireless stereo earbuds and hearing aids. The software release for the nRF5340 is available now under commercial license to enterprise customers.
LE Audio is the next generation of lower power, higher quality Bluetooth audio that operates on the Bluetooth Low Energy (LE) radio. LE Audio introduces new capabilities like broadcast audio, multi-stream synchronized audio, and a new high-quality audio codec called LC3. A demonstration of broadcast audio with Packetcraft's software running an LC3 codec on the nRF5340 can be viewed here.
Packetcraft's Bluetooth LE Audio consists of the following software components: Packetcraft Controller, a Bluetooth 5.2 qualified link layer, and Packetcraft Host, a Bluetooth 5.2 qualified host stack and profiles. Packetcraft Controller supports the full Bluetooth 5.2 link layer feature set, including isochronous channels and LE power control, in addition to Bluetooth 5.0/5.1 features like 2 Mbps, long range, extended advertising, and AoA/AoD direction finding. Packetcraft Host supports the full Bluetooth 5.2 LE host stack feature set, with support for EATT, plus profile software supporting the new Bluetooth specifications defining LE Audio.
"The high performance nRF5340 allows Packetcraft's software to be used to its fullest potential," says John Yi, CEO of Packetcraft. "Hardware features like dual Arm Cortex-M33 cores and the low-jitter audio PLL enable our software to meet the challenging requirements of products like synchronized wireless stereo earbuds."
