This application is simple demo how to connect to Wi-Fi, a utility to test the connectivity. It can be used with any board with connected interface (ETHERNET, GPRS, etc ), but not tested.
It was based on the oficial sample Wi-Fi Demo <https://docs.zephyrproject.org/latest/samples/net/wifi/README.html>.
It was tested with STM32L4+ Discovery kit IoT B-L4S5I-IOT01A from
ST Microelectronics.
<https://www.st.com/en/evaluation-tools/b-l4s5i-iot01a.html>
This sample adds to the console commands, to easy test the connectivity.
Connect a terminal to Zephyr Console, and test with this commands.
// Connect to Wi-Fi, if not connected
Wi-Fi connect <<SSID>> <<PSK>>
Connection requested
Connected
// Connect to Wi-Fi, if not connected
>nc tcp <<Ip Adress>> <<Port>>
CONNECTED. Use CTRL+D to disconnect.
Hello from my board using TCP!
Hello from server!
DISCONECTED
>
>nc udp <<Ip Adress>> <<Port>>
CONNECTED. Use CTRL+D to disconnect.
Hello from my board using UDP!
Hello from server!
DISCONECTED
>
After a successfull connection it keeps a open socket to send and receive throwght the console. CTRL + D to disconnect the socket.
A Zephyr development environment configured, see: <https://docs.zephyrproject.org/latest/getting_started/index.html>
A board with IP connectivity, like B-L4S5I-IOT01A properly configured.
For WI-FI autoconnect, the expects a if with the label wifi0.
Build and flash Zephyr Demo Wifi as follows, changing b_l4s5i_iot01a to your board:
.. zephyr-app-commands:: :zephyr-app: szephyr-demo-wifi :board: b_l4s5i_iot01a :goals: build flash :compact:
After flashing, you should be able to access the console and test the commands.
