3.3 WICED Software Examples

3.3.1 Finding demo and code snippets

The 43xxx_Wi-Fi/apps folder is the place to go for example code to run with your Sterling-LWB STM Expansion
Board. Note that not all demo and snip projects distributed with the WICED SDK are designed for use with all radio
modules.
This guide will highlight several that are known to work properly with basic Wi-Fi and Bluetooth functionality on
the Sterling-LWB (BCM4343W). Some projects, may not be supported on the BCM4343W or may require code
modifications to either the demo/snip code or the WICED SDK to function properly.
IMPORTANT: For snip or demo projects whose .mk file specifies a "VALID_PLATFORMS" entry, you must add the
following line to the .mk file to allow building the project for the Sterling-LWB platform:
VALID_PLATFORMS

330-0234-R1.2
+= LSRSTERLING_00950
Description
Demonstrates how to use printf() and scanf() c library functions to interact with the debug UART
Demonstrates use of the WICED APIs for manipulating general purpose I/O (GPIO)
Demonstrates use of SPI for master and slave device configurations via the WICED SDK API
Demonstrates use of UARTs via the WICED SDK API
Demonstrates use of the Device Configuration Table (DCT) used throughout the WICED SDK
Description
Demonstrates Wi-Fi client mode, ICMP ping, MCU powersave and Wi-Fi powersave. Takes Wi-Fi
network configuration from "43xxx_Wi-Fi/include/default_wifi_config_dct.h".
Demonstrates performing a Wi-Fi AP scan. Results of the scan are displayed on the debug UART
Demonstrates use of "Soft AP" mode and "client" mode simultaneously
Basic example of a TCP/IP client
Basic example of a TCP/IP server
Basic example of transmitting UDP packets
Basic example of receiving UDP packets
Description
Demonstrates a simple BLE peripheral that advertises a simple "hello" service for learning
the WICED SDK BLE apis. For more information on the BLE APIs, see 43xxx_Wi-
Fi/doc/API.html
Demonstrates simultaneous BLE GATT and Bluetooth Classic RFCOMM servers
At the time of publishing this document, there is not a snippet that demonstrates BLE
central role even though the SDK supports it. To find API features related to BLE central
role, refer to the "43xxx_Wi-Fi/doc/API.html" documentation under the
"Components->Bluetooth->Device Management->BLE" section for details.
