Silicon Labs Aliro#

Aliro is an open access-control standard from the Connectivity Standards Alliance (CSA). It defines how smartphones, wearables, and other credential devices securely communicate with electronic locks and access readers using Near Field Communication (NFC), Bluetooth Low Energy (BLE), and optionally Ultra-Wideband (UWB).

The Silicon Labs Aliro Extension delivers a certifiable Aliro reader implementation on EFR32MG24 and EFR32MG26 wireless MCUs, with sample applications for a standalone reader and a Matter door lock with integrated Aliro access. The software is packaged as an extension to the Silicon Labs Simplicity Software Development Kit (SDK, also SiSDK) supported in Simplicity Studio.

Obtaining the Software#

The Aliro software package is available upon request. Contact the Sales team to arrange access.

Path for Development#

Follow this sequence to go from first install to a working demo:

  1. Understand Aliro: Read what the protocol is, how it relates to Matter, and which transports it supports: For more information, see Aliro Fundamentals.

  2. Set up your environment: Install Simplicity Studio 6, the Simplicity SDK, the Aliro extension, and connect the reference hardware: For more information, see Getting Started.

  3. Build and flash an example: Create a project from an Aliro template and flash firmware. For more information, see Build and Flash Example.

  4. Run a demo: Choose one validation path after flashing:

    • Apple Home Demo — Commission AliroMatterLock and exercise Wallet tap-to-unlock

    • Test Tool Demo — Validate reader flows with the CSA Aliro Test Tool

  5. Go deeper: Learn NFC porting, application customization, and project configuration. For more information, see Developer's Guide.
