Silicon Labs Thunderboard BG22 产品指南说明书
BG22 Lab 1: Out-of-the-box Thunderboard Example ProjectThese lab procedures walkthrough programming the EFR32BG22, creating a Bluetooth beacon out of the box and introduce the development tools we will be using throughout this workshop, including our new EFR Connect Bluetooth development app.Getting StartedGetting StartedReview the following material before starting the Bluetooth 5 labs. Ensure that you have the correct hardware and software to successfully complete the labs.1.1 Hardware Requirements• 1 Thunderboard TM BG22 Kit• 1 Micro USB cable•iOS or Android Mobile device1.2 Software Requirements•Simplicity Studio v4 (Windows.exe, Mac.dmg, Linux .tar )o Bluetooth SDK 2.13.4o Gecko SDK Suite 2.7.4•EFR Connect Mobile App1.3 Simplicity Studio InstallationOption 1 New Installation – Offline Installer1. Install Simplicity Studio v4 b y launching Offline Installer (Windows.exe, Mac.dmg, Linux .tar )2. You’ll need to create or sign in with your accountOption 2 - Studio Previously Installed with Other SDKs1. Update existing Simplicity Studio Installation2. Update Protocol SDKs by clicking menu bar Help -> Update Software.a. Click Package Managerb. Click on tab for “SDKs” in Package Manager windowi. Select and Install Bluetooth SDK – 2.13.4.0ii. Select and Install Gecko Platform – 2.7.42 GATT CONFIGURATOR TO CUSTOMIZE BLUETOOTH PROJECTSSilicon Labs provides example projects that help evaluate different features of their Bluetooth solutions. This lab starts by loadinga wireless starter kit with an example of a Thermometer device. Using the default image in a large group can cause issues whenall of the devices broadcast the same device name.The GATT Configurator in Simplicity Studio makes it easier to modify the characteristics within a Bluetooth device. Complete the following steps to help distinguish your wireless starter kit.2.1 Create SoC Example ProjectWith Simplicity Studio open:1. Plug Wireless Starter Kit into USB Port. Click on the kit listed under Debug Adapters in upper left.2. Click on the Getting Started Tab from the Launcher dashboard in Simplicity Studio.3. Click on the SoC-Empty project listed under Software Examples.234. Click Yes when asked to switch to Simplicity IDE perspective and create the project.42.2 Modify GATT File for Empty ProjectThe BLE GATT Configurator window should be displayed in the Simplicity IDE once the project is created.(Note: If not shown, Click soc-empty.isc in the Project Explorer pane on the left)1. Click on Generic Access and then Device Name under the Custom BLE GATT list in upper right.2. Under Value settings, change the value from “Empty Example” to your INITIALS and set length to 2 bytes.123. Now add a new service by clicking on the Add button in the upper right corner and selecting New Service4. Select the new Service5. Add a new characteristic by clicking on the Add buttonin the upper right corner and selecting New Char-acteristic6. Now select the new characteristic7. Change the name to Read_Write8. Tick the checkbox next to the ID field in the Characteristic settings 9. Set the ID to “Read_Write ” 10. Set the Value to “R ”11. Set the Value type to utf-8 12. Set the Length to 113. Add Read property by clicking on the Add button in the Properties tab and selecting Read 14. Add Write property by clicking on the Add button in the Properties tab and selecting Write15. Click Generate to have the modifications updated in the project GATT file. 16. Click OK through the pop-up windows.452.3 Program Thunderboard with Empty Project1. Click Build icon in the tool bar at the top of the Simplicity IDE.The project will compile based on its build configuration.Note: You may need to select the project in the Project explorer view on left2. Press the Debug icon in the tool bar. This will flash the project onto the board if it was successfully built. Thisonly updates the program memory.Error: DP Write Failed - Press the Reset button on Thunderboard or unplug/replug then Flash again within 30 seconds.The Thunderboard demo app which ships on the boards goes into a low energy mode (EM2) after 30 seconds. When the device is in EM2, the debug interface is unavailable, and DP write fails. We can wake the device by resetting Thunderboard.3. A device selection prompt will appear select your J-Link device4. Next Click to Query the Lock Status5. Click OKNote: The prompt to select the device and the “Click to Query Lock Status” is expected for EFRBG22. Studio doesn’t know if the device is secure debug locked or not. The only way to know is to send a DCI command which will reset the part. So, we don’t allow any DCI commands to run in the background without user intervention. Studio caches the status, so you’ll only see this happen the first time you use the device and when you re-connect the device.6. Once the project is flashed, the Debug perspective will be shown. Click the Resume icon in the tool bar tohave the application start.7. Click the Disconnect icon in the tool bar to end the Debug session.12 34567READ/WRITE GATT CHARACTERISTICS WITH EFR CONNECT MOBILE APP3 READ/WRITE GATT CHARACTERISTICS WITH EFR CONNECT MOBILE APPWith the launch of BG22 we also release our new Bluetooth Development app, EFR ConncectNew features offered by EFR Connect:•Simultaneous connections with multiple Bluetooth Low Energy peripherals•Bluetooth communication logging•Advanced filtering for device discovery•Custom naming for services and characteristicsInstall/Open EFR Connect off your mobile app store to modify the name of your BG22 device.1. Press Develop and select Browser to view nearby Bluetooth Devices.2. Press the Filter tab to narrow your search and find your device.3. Input your INITIALs and press search4. Connect to your device to view the GATT Profile and Characteristics.Note: Generic Services (UUID: 1800) shown below will not appear on iOS as Apple does not these to be visible to applications.5. Tap Unknown Service and edit its name to Custom Service.6. Tap Unknown Characteristic and edit its name to Read_WriteNote: there is no standard way of displaying the names of custom services/characteristics. When the app sees a 128-bit UUID it knows that it's custom, so the name is always "Unknown service", this is the same for most generic BLE apps out there.The workaround is to have your own app and then write the service name into a characteristic so that your app can read it from there. EFRConnect takes care of this to ease development.7. Under you’re Read_Write characterstic Tap Write.8. Write W for your device to modify this characteristic and hit Save.EFRConnect can be used to devlop and test your GATT Services and Characteristics.234156 7 84 TROUBLESHOOTING4.1 Problem Occurred: ‘Programming Flash’ has encountered a problem. DP write failedThe Thunderboard demo app which ships on the boards goes into a low energy mode (EM2) after 30 seconds. When the device is in EM2, the debug interface is unavailable, and DP write fails. We can wake the device by resetting Thunderboard. Press the Reset button on Thunderboard and Flash again within 30 seconds.If problem persists, we can force a ‘D evice info’ DCI command to trigger a reset, which restores access.The most direct way to do this is to ‘Recover Bricked Device’ using Simplicity Commander Tool1. Navigate to Launcher Window2. Verify your device is selected3. Click Compatible Tools Tab4. Open Simplicity Commander5. Connect to Adapter6. Connect to Target7. Select Flash8. Click Recover bricked Device1 2345678Note: This erases the image on the chip including the bootloader which is necessary for Bluetooth applications. Next section goes over a quick way to flash a bootloader to your device.4.2 SoC-Empy Example Doesn’t Appear in EFR ConnectAfter flashing the Thunderboard with the SoC-Empty image, you may not see it in the EFR Connect App if the device has no bootloader present. The bootloader is a program stored in resereved flash memory that can initialize the device update firmware imgages and possible perform some integrity checks. Out of the box, the Thunderboard Demo includes a boot-loader image that will not be overwritten when a device is flashed with other examples unless otherwise dictacted by the user. To quickly replace a bootloader image, you can simply flash your device with one of the pre-built Demos in Simplicity Studio when you select your device from the debug adapters pane.Flashing SoC-Empty Demo will run the empty beacon on Thunderboard with ‘Empty Example’ as the device name and no additional GATT service added in Lab 1.1. Navigate to Launcher Window2. Verify your device is selected3. Click Getting Started tab4. Expand Bluetooth (SoC) Basic under Bluetooth SDK Demos5. Click ‘SoC –Empty’6. In the Pop-Up verify the mode is set to Run.7. Click Start.1234567。
