Simplicity Connect Mobile Application

This is the source code for the Simplicity Connect mobile application.

What is Simplicity Connect BLE mobile app?

Silicon Labs Simplicity Connect is a generic BLE mobile app for testing and debugging Bluetooth® Low Energy applications. With Simplicity Connect, you can quickly troubleshoot your BLE embedded application code, Over-the-Air (OTA) firmware update, data throughput, and interoperability with Android and iOS mobiles, among the many other features. You can use the Simplicity Connect app with all Silicon Labs Bluetooth development kits, Systems on Chip (SoC), 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.

After connecting the Simplicity Connect app and BLE hardware (e.g., a dev kit), the Blinky test on the app shows a green light indicating when your setup is ready to go. The app includes simple demos to teach you how to get started with Simplicity Connect and all Silicon Labs development tools.

The Browser, 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

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

Blinky: The ”Hello World” of BLE – Toggling a LED is only one tap away.
Throughput: Measure application data throughput between the BLE hardware and your mobile device in both directions
Health Thermometer: Connect to a BLE hardware kit and receive the temperature data from the on-board sensor.
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) while keeping the light status in sync across all devices.
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: 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.
Bluetooth Electronic Shelf Labels (ESL): Adds and commissions ESL tags to the system network by scanning the tag's QR code with the mobile device's camera and provides the user a UI to view the list commissioned tags and control them.
Matter: Commission and control of the Matter devices over Thread and Wi-Fi.
Wi-Fi OTA Firmware Update: The Wi-Fi OTA firmware update demo demonstrates how to update the SiWx91x user application firmware over Wi-Fi connection, by downloading the image from the mobile phone.
Wi-Fi 917 Sensors: The Wi-Fi 917 Sensor demo demonstrates to read and display sensor data from 917 Dev Kit.

Development Features

Simplicity Connect helps developers create and troubleshoot Bluetooth applications running on Silicon Labs’ BLE hardware. Here’s a rundown of some example functionalities.

Bluetooth Browser - A powerful tool to explore the BLE devices around you. Key features include:

Scan and sort results with a rich data set
Label favorite devices to surface on the top of scanning results
Advanced filtering to identify the types of devices you want to find
Save filters for later use
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 modesREADME.md
Configurable MTU and connection interval
All GATT operations

Bluetooth Advertiser – Create and enable multiple parallel advertisement sets:

Legacy and extended advertising
Configurable advertisement interval, TX Power, primary/secondary PHYs
Manual advertisement start/stop and stop based on a time/event limit
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

Runs a sequence of BLE operations to verify interoperability
Export results log

Building Simplicity Connect from the source code

Clone the project repository
Open the project directory in Android Studio
Wait for Gradle sync to finish
In the Build Variants tool window, select the desired variant: release (blueGeckoRelease) or debug (blueGeckoDebug)
Build the project with Build > Build Project and run it on a connected mobile device with Run > Run 'mobile' or Run > Debug 'mobile'
You can also build an APK installation package with Build > Build Bundle(s) / APK(s) > Build APK(s)... - the APK will be built, and a link to its location on the disk displayed in a notification in Studio.

Development

The main application code lies in the <project_directory>\mobile\src\main\java\com\siliconlabs\bledemo directory. The main application screen's code can be found there in the home_screen directory, while the application features (scanner, IOP test, advertiser/server configuration, all the demos) are separated into corresponding directories in the the features directory. The application architecture mostly follows the MVVM (Model-View-Viewmodel) pattern, and the feature/demo directories contain their own views, model and viewmodels. Handling the Bluetooth operations is covered mainly by the code in the bluetooth directory, most importantly the BluetoothService class. GATT service/characteristic/descriptor definitions are contained in <project_directory>\mobile\src\main\java\assets.

Additional information

The app can be found on the Google PlayStore and Apple App Store.
