​

RapidLaunch is now delivering optimized Bluetooth Low Energy (LE) performance, completing the planned support for Bluetooth® 5.4, and introducing a refactored Audio Manager designed for seamless integration across Classic Audio and LE Audio use cases.

​

Built for Today — Ready for the Future

With the Bluetooth SIG reporting that 99% of all Bluetooth® devices shipped in 2030 will include Bluetooth® LE, supporting both power-efficient and feature-rich LE use cases will become increasingly important. RapidLaunch has been updated to provide optimized LE single‑mode support, full Bluetooth 5.4 feature coverage, and a modernized audio subsystem. These updates deliver meaningful performance gains and architectural flexibility for developers building the next wave of Bluetooth‑enabled products.

At the core of this release is support for the optimized LE single‑mode, introduced in Blue SDK 7.3, enabling RapidLaunch to be compiled for leaner, more efficient LE‑only deployments. This enhancement allows developers to reduce system overhead while maintaining robust Bluetooth performance—ideal for power‑ and resource‑constrained applications.

​

Refactored Audio Manager for Modern Audio Use Cases

In addition to wireless protocol enhancements, RapidLaunch introduces a refactored Audio Manager with updated voice channel handling. The new architecture allows developers to create independent capture and playback streams, enabling smoother and more flexible audio workflows.

This update is designed to support seamless coexistence of Classic Audio and LE Audio, reducing integration complexity and positioning RapidLaunch for next‑generation Bluetooth audio applications, including advanced voice, media, and hybrid audio scenarios.

​

Completing Bluetooth 5.4 Support with Advanced Advertising Control

This release also marks the completion of RapidLaunch’s Bluetooth 5.4 support with the addition ofAdvertising Coding Selection for the LE Coded PHY.

​

Bluetooth Low Energy supports multiple physical layers (PHYs) within the Bluetooth chip; each designed for different data rates and range characteristics. With Advertising Coding Selection, the Host now has direct control over the coding scheme used when leveraging the LE Coded PHY for extended advertising.

This capability empowers developers to fine‑tune the balance between throughput and range, making it easier to optimize for diverse use cases such as long‑range device discovery, infrastructure beacons, and low‑power IoT deployments. By exposing this level of control, RapidLaunch enables more intentional and efficient wireless design decisions.
