What's the difference between the EFR Connect and Simplicity Connect (Si Connect) mobile apps from Silicon Labs?

Answer

The EFR Connect app has been rebranded as Simplicity Connect (or Si Connect for short) with the release of version 2.9.0 for both Android and iOS in September 2024. This update reflects the app’s evolution beyond Bluetooth Low Energy (BLE) to also include support for Wi-Fi and Matter protocols. The rebranding aligns the app with Silicon Labs' Simplicity Studio 5, creating a unified tool for developers who are working with multiple wireless technologies. Simplicity Connect retains *all* the features of EFR Connect while introducing new functionality to support the expanded protocols, making it even more versatile and easier to use.
