Download EFR Connect app on your smartphone and speed up development now!
EFR Connect is a generic BLE mobile app for fast and easy Bluetooth® Low Energy development.
You can quickly test and debug your BLE embedded application code, Over-the-Air (OTA) firmware update, data throughput, and interoperability with Android and iOS mobile devices.
Troubleshooting with EFR Connect is a breeze. The app indicates when your setup is ready to go. Its many features help you to fix bugs in no time and test data throughput and mobile interoperability with a tap of a button on the app. The out-of-the-box demos familiarize you with EFR Connect and the entire Silicon Labs development ecosystem. For an in-depth analysis, you can use our Network Analyzer to see the packet trace data.
EFR Connect works with all Silicon Labs Bluetooth development kits, SoCs, and modules.
