Zephyr Demo Wifi and TCP/UDP connection console using STM32L4+ B-L4S5I-IOT01A

Zephyr Demo Wi-Fi and TCP/UDP connection console ######

Overview

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.

Usage

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.

Requirements

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.

Building and Running

Build and flash Zephyr Demo Wifi as follows, changing b_l4s5i_iot01a to your board:

After flashing, you should be able to access the console and test the commands.
