About EFR Connect

The Silicon Labs EFR Connect app utilizes the Bluetooth adapter on your phone/tablet to scan, connect and interact with BLE devices.

The app is divided into two main functional areas, the demo and the develop view.

The demo view lists a number of demos that are meant for quickly testing some of the sample apps in the Silicon Labs GSDK. The currently supported demos are:

- Health Thermometer demo: Connects to an EFR32/BGM device running the soc-thermometer sample application from the Bluetooth SDK and displays the temperature read from the SI7021 sensor on the WSTK mainboard.
- Connected Lighting DMP demo: Leverages the DMP sample apps to control a DMP light node from both a mobile app as well as the protocol specific switch node (Zigbee, proprietary) while keeping the light status in sync across all devices.
- Range Test demo: Allows visualizing the RSSI and other RF performance data on the mobile phone while running Range Test sample application on a pair of Silicon Labs radio boards.

The develop view contains functionalities focused on helping developers create and troubleshoot their Bluetooth applications based on EFR32/BGM devices. The currently supported functionalities are:

- Bluetooth Browser: This is a generic and powerful tool that allows you to explore the BLE devices around you. Key features of the browser include:
* Scan and sort results with rich data set
* Ability to favorite devices on the scan list so that they surface to the top
* Advanced filtering options to quickly identify the devices you want to find
* Option to save filters for later use
* Support for multiple connections
* Support for Bluetooth 5 advertising extensions
* Ability to rename services/characteristics with 128-bit UUIDs (mappings dictionary)
* Over-the-air (OTA) device firmware upgrade (DFU) with both reliable and speed modes
* Configurable MTU and connection interval
* Support for all GATT operations
- Bluetooth Advertiser: Allows you to create multiple advertisement sets and enable them in parallel
* Supports legacy and extended advertising
* Configurable advertisement interval, TX Power, primary/secondary PHYs
* Ability to manually start/stop advertisement, or stop based on time/event limit
* Support for multiple AD types
