Software and Firmware on GitHub
The Metirionic Channel Sounding Evaluation Kit is now distributed through the official Metirionic GitHub organization.
This gives developers direct access to the latest firmware source code, precompiled firmware images, documentation, release notes, and future updates.
The Channel Sounding firmware is available as open source under the MIT License, including precompiled firmware images for quick evaluation. The Metirionic PC Evaluation Application is provided separately and requires an activation key (license), which can be requested by contacting contact@metirionic.com.
Channel Sounding Firmware for Nordic nRF54L15
The firmware for supported Nordic nRF54L15-based development boards is available in the following repository:
Firmware source code:
https://github.com/Metirionic/mars-cs-nrf54l
The repository supports two evaluation approaches:
- Flash precompiled firmware for a quick start without setting up a development environment.
- Build the firmware from source to customize the firmware or integrate it into your own development workflow.
Channel Sounding requires two compatible boards: one configured as the initiator and one as the reflector. The repository contains firmware variants and documentation for both roles.
