Does Lyra support Bluetooth LE Audio and/or the Low Complexity Communications Codec (LC3)?
Lyra is based on the EFR32BG22 SoC which is a single-chip solution from Silicon Labs. Both Lyra S (SIP) and P (PCB) are Bluetooth 5.3 modules, but do not support any LE Audio and Low Complexity Communications Codec (LC3) features. Please note that by now Silicon Labs does not offer or released yet a Bluetooth audio stack.
LE Audio is the next-generation Bluetooth standard defined by the Bluetooth Special Interest Group (SIG) and offers enhanced performance in power consumption, latency, and bandwidth. Bluetooth LE Audio differs from Classic Bluetooth (also known as Bluetooth BR/EDR) by operating on the Bluetooth Low Energy (BLE) radio.
LC3 (Low Complexity Communication Codec) is an audio codec which was introduced within the Bluetooth LE audio specification. Simply put, you can say that an audio codec allows to compress the audio stream at the source and can be decompressed at the receiving end. It was designed as a low complexity communications codec to deliver high-quality speech and audio streaming.
