What is the Simplicity Connect app? Silicon Labs Simplicity 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 Simplicity 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 Simplicity Connect app with all Silicon Labs Bluetooth development kits, System-on-Chips (SoCs), and modules. Why download Simplicity Connect? Simplicity Connect radically saves the time you will use for testing and debugging! With Simplicity Connect, you can quickly see what's wrong with your code and how to fix and optimize it. Simplicity 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 Simplicity 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. App includes simple demos to teach you how to get started with Simplicity 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. Simplicity 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. - Wi-Fi OTA Update: Firmware update to SiWx91x over wifi. Development Features Simplicity Connect helps developers create on Silicon Labs' BLE hardware. Bluetooth Scanner - A powerful tool to explore the BLE devices around you. - Scan and sort results with a rich data set - Advanced filtering to identify the types of devices you want to find - Multiple connections - Bluetooth 5 advertising extensions - Rename services and characteristics with 128-bit UUIDs (mappings dictionary) - Over-the-air (OTA) device firmware upgrade (DFU) in reliable and fast modes Bluetooth Advertiser – Create and enable multiple parallel advertisement sets: - Legacy and extended advertising - Configurable advertisement interval, TX Power, primary/secondary PHYs - Support for multiple AD types Bluetooth GATT Configurator – Create and manipulate multiple GATT databases - Add services, characteristics and descriptors - Operate the local GATT from the browser when connected to a device - Import/export GATT database between the mobile device and Simplicity Studio GATT Configurator Bluetooth Interoperability Test – Verify interoperability between the BLE hardware and your mobile device Simplicity Connect Release Notes: https://docs.silabs.com/mobile-apps/latest/mobile-apps-release-notes/ Learn more about Simplicity Connect mobile app: https://www.silabs.com/developers/simplicity-connect-mobile-app

Reported bugs

4 issues
  • Can't read data from Bluetooth device
  • Tries to ask for Bluetooth connection when Bluetooth is off. Asks to connect to devices when Bluetooth is off. Who knows what this app is doing in the background without permission?! What ever it is , it ain't good
  • Tapping "tabs" doesn't work (nothing changes in the UI). To get some response from tapping UI controls typically requires (a) launching nRF Connect, (b) switching to another app, (c) switching back to nRF Connect. I've tried uninstalling and re-downloading. Same result. This used to be the bee's knees of BLE tools but it's only worth 1 star at the moment (v2.7.11).
  • Cant go past the initial announcement. The app is unresponsive to the taps.
