EFR Connect BLE Mobile App

What is EFR Connect BLE mobile app? 

Silicon Labs EFR Connect is a generic mobile app for testing and debugging Bluetooth® Low Energy (BLE) applications. It can help developers to create and troubleshoot BLE applications running on Silicon Labs' development boards. With EFR Connect, you can quickly troubleshoot your BLE embedded application code, Over-the-Air (OTA) firmware update, data throughput, interoperability, and many other features. You can use the EFR Connect app with all Silicon Labs Bluetooth development kits, System-on-Chips (SoCs), and modules.

Why download EFR Connect? 

EFR Connect radically saves the time you will use for testing and debugging! With EFR Connect, you can quickly see what's wrong with your code and how to fix and optimize it. EFR Connect is the first BLE mobile app allowing you to test data throughput and mobile interoperability with a single tap on the app.

How does it work? 

Using EFR Connect BLE mobile app is easy. It runs on your mobile devices such as a smartphone or tablet. It utilizes the Bluetooth adapter on the mobile to scan, connect and interact with nearby BLE hardware.

The app includes simple demos to teach you how to get started with EFR Connect and all Silicon Labs development tools.

The Scanner, Advertiser, and Logging features help you to find and fix bugs quickly and test throughput and mobile interoperability simply, with a tap of a button. With our Simplicity Studio's Network Analyzer tool (free of charge), you can view the packet trace data and dive into the details.

Demos and Sample Apps

EFR Connect includes many demos to test sample apps in the Silicon Labs GSDK quickly. Here are demo examples: 

- Blinky: "Hello World" of BLE 
- Throughput: Measure application data throughput
- Health Thermometer: Receive data from the temperature sensor on-board sensor Silicon Labs kits.
- Connected Lighting DMP: Leverage the dynamic multi-protocol (DMP) sample apps to control a DMP light node from a mobile and protocol-specific switch node (Zigbee, proprietary). 
- Range Test: Visualize the RSSI and other RF performance data on the mobile phone while running the Range Test sample application on a pair of Silicon Labs radio boards.
- Motion: Display the data from the accelerometer in a user-friendly way.
- Environment: Display the collection of sensor data read from the compatible Silicon Labs development kit.
- WiFi Commissioning: Perform the commissioning of a Wi-Fi development board.
- Matter: Commission and control of the Matter devices over Thread and Wi-Fi.
