BLE 5.4 Linklayer, Stack & Profiles IP

Description and Features

BlueLitE is a Bluetooth core certified by BT SIG to meet the specifications version 5.3 (Bluetooth low energy) for single mode. The BlueLitE product line has two component IPs. The BlueLitE-SP (Stack and Profiles) and the BlueLitE-LP (Link layer and Physical layer). The v5.3 (Milan) Specifications include the core Protocol Stack and Link Layer specification to support Audio-over-BLE. Generic Audio Middleware Specifications are being defined Bluetooth SIG Working Groups and are Software only specifications to enable Audio-over-BLE. Low Complexity Communication (LC3) codec has recently completed its spec adoption by BT SIG. We already have the product licensed by customers and being integrated.
