The ThunderBoard React sample application in the BLE C SDK 1.0.4 is not compiling correctly. As a workaround, users can install the 1.0.2 BLE C SDK until the sample application is fixed in a later BLE C SDK release. After installing the stack it must be added to Simplicity Studio:
In Simplicity Studio:
Click the cogwheel in the upper left (V4) or right (V3) hand corner of the launcher screen to enter the Simplicity Studio Preferences.
Under the Simplicity Studio->SDKs tab click Add... and navigate the folder you installed the SDK to. By default this is located at "C:\SiliconLabs\BluetoothSmartSDK\22.214.171.124-GA".
To open the ThunderBoard React Sensors sample application:
Open the Simplicity IDE and go to File->New->Silicon Labs AppBuilder Project in V3 or File->New->Project...->Silicon Labs AppBuilder Project in V4.
Select Silicon Labs Bluetooth Smart SoC Framework
Uncheck the "Start with a blank application" checkbox and select "SOC demo - ThunderBoard-React Sensors" from the list and click Next.
Find a suitable project name and click Next.
Make sure Kit is set to ThunderBoard React Kit. The Part should then automatically be set to EFR32BG1B232F256GM48. Click Finish.
Click the Generate button before you click the compile button (hammer).
