Cloud2GND is proud to announce the release of firmware version 1.1 for the Aurawave AW100PA. This update brings a collection of additions that make the platform more flexible and easier to integrate across a wider range of product designs.
Since launching the Aurawave AW100, Cloud2GND has been working closely with Auracast™ and Bluetooth® LE Audio product teams to understand how they’re using the platform and what they need from it. Firmware v1.1 is a direct response to that feedback, bringing a collection of targeted enhancements that make the Aurawave more flexible, easier to integrate, and better suited for a wider range of product designs.
If you’re new to Aurawave, the AW100 series modules from Cloud2GND and Ezurio give engineering teams a fast path to building Auracast™ and Bluetooth® LE Audio products. Built on Ezurio’s BL5340PA module, powered by Nordic Semiconductor’s nRF5340 SoC, the AW100 combines long-range wireless audio performance (up to 250m free-space range), a high-quality AKM audio codec, and Cloud2GND’s Aurawave Audio Framework, all accessible through a simple AT command interface. The platform is designed to let developers configure and deploy LE Audio functionality without working directly with the Bluetooth specification, supporting both standalone and host-managed operation.
Firmware v1.1 builds on that foundation with improvements that directly address the needs of teams moving from prototyping to production.
What’s New in Firmware v1.1
Custom USB Device Identification – Product manufacturers can now assign a custom USB Vendor ID and Product ID to the board. When a finished product is connected to a host computer, it appears under the manufacturer’s own product name rather than a generic label, an important step for teams building branded commercial products on the Aurawave platform.
AT Command Interface Improvements – The AT interface now automatically handles all common line-ending formats, ensuring consistent behavior across Windows, macOS, and Linux hosts without manual configuration. Commands can also be edited using the backspace key before sending, a small but useful improvement for anyone working with the board interactively.
UART Interface via the 40-Pin Header – For systems without USB host capabilities, the AT interface can now be routed through the 40-pin expansion header, allowing any host processor to communicate with the board directly over hardware serial, without relying on USB. This makes it straightforward to incorporate the AW100 into a wide range of embedded product designs, regardless of the host platform.
I2S Audio Input via Auxiliary Port – Systems with their own audio sources can now provide digital audio to the AW100 over I2S via the auxiliary port on the 40-pin header, providing an additional option in addition to USB audio input. This opens up integration paths for a broader range of product designs where the host system handles audio sourcing directly.
Persistent Sink Demo Mode – Sink Demo Mode can now be saved to flash memory, so the board boots directly into Sink Demo Mode with no host computer required after initial setup. When in Sink Demo Mode, the LED flashes green while the device searches for a broadcast and turns solid green once it has synchronized to one, making it easier to determine the board’s state at boot.
Sink demo mode allows users to easily test and demonstrate end-to-end audio use cases, with one board streaming audio and one or more boards receiving audio without needing a host device. This enables the AW100 to be integrated into enclosures and to demonstrate full Auracast use cases.
Audio Stream Language and Location Tagging – Two new configuration options have been added to the audio stream setup. The language of a subgroup of streams can now be configured, allowing developers to set the appropriate language tag for their broadcast. Additionally, each stream can be tagged with a speaker location (left, right, center, mono, and more). While these are metadata-level additions rather than new audio routing capabilities, they are useful in specific scenarios, particularly tagging streams as mono to ensure audio plays correctly in both earbuds.
