5.2 Building and Downloading the Sensor Demo

To start using the sample project, place the "sterling_demo" folder from the downloaded archive into

the '43xxx_Wi-Fi/apps/demo' subfolder of your WICED SDK installation. Make sure you have already

installed the Sterling-LWB platform files as described in section 3.2.4.

If you have WICED Studio open, you may need to refresh the Project Explorer view by right-clicking the

top-level folder and clicking "Refresh". At this point, you will see a new project available under the

43xxx_Wi-Fi/apps/demo/sterling_demo folder. You can review the sterling_demo.c file for more details

on what this project demonstrates. To build, download and run the project, create a new make target:

demo.sterling_demo-LSRSTERLING_00950-ThreadX-NetX-SDIO download download_apps run

This will trigger a series of steps that can be monitored in the WICED Studio console view. After building

the source code, if your expansion board is attached via USB and drivers are installed the application will

be programmed onto the STM32F411 Discovery Board and start running once the process has

completed.

Once the sensor demo is running on your discovery board, you can open a serial terminal on the USB

Serial adapter associated with your expansion board (see Device Manager for a list of COM ports on

Windows) to view debug output. The serial terminal settings should be set to 115200 baud, 8 data bits,

no parity, 1 stop bit. The debug output gives developers a view into the steps the application is taking

such as enabling Wi-Fi, enabling BLE, joining a Wi-Fi network, reading sensor data and reporting to the

cloud.
