More about EFR Connect
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.

EFR Connect - Demo View
The EFR Connect BLE mobile app is divided into two main functional areas, the Demo view and Develop view. The Demo view provides you with demos for quickly testing sample apps on the Silicon Labs GSDK, which is available via Simplicity Studio.
EFR Connect includes the following demos:
- Blinky Demo: The ”Hello World” of BLE – Toggling a LED is only one tap away.
- Throughput Demo: Measure application data throughput between the BLE hardware and your mobile device in both directions
- Health Thermometer Demo: Connect to a BLE hardware kit and receive the temperature data from the on-board sensor.
- Connected Lighting DMP Demo: Leverage the dynamic multi-protocol (DMP) sample apps to control a DMP light node from a mobile and protocol-specific switch node (Zigbee, proprietary) while keeping the light status in sync across all devices.
- Range Test Demo: Visualize the RSSI and other RF performance data on the app while running the Range Test on a pair of Silicon Labs radio boards.
- Motion: Control a 3D render of a Silicon Labs Thunderboard or Dev Kit that follows the phyiscal board movements.
- Environment: Read and display the data from the on-board sensors on a Silicon Labs Thunderboard or Dev Kit.
- Wi-Fi Commissioning: Commission a Wi-Fi device over BLE.
EFR Connect - Develop View
The Develop view contains several useful functionalities to help you create and troubleshoot embedded Bluetooth applications based on EFR32/BGM devices. Here is a rundown of the main functionalities:
- Bluetooth Browser: A generic and powerful tool for exploring the nearby BLE devices
- Bluetooth Advertiser: Create multiple advertisement sets and enable them in parallel
- Bluetooth GATT Configurator: Create and manipulate multiple GATT databases;
- Bluetooth Interoperability Test: Verify interoperability between Silicon labs BLE hardware/software and your mobile device
