Software Description

Developed on Edgi-Talk platform.
Example features:
- Wi-Fi scanning
- Wi-Fi connection
- Iperf performance test
Provides a clear example of Wi-Fi driver integration with RT-Thread.

Usage

Build and Download

Open and compile the project.
Connect the board USB to PC via DAP.
Flash the compiled firmware.

Running Result

After power-on, the system initializes the Wi-Fi device.
Connect to a Wi-Fi network via serial terminal:

wifi scan

wifi join <SSID> <PASSWORD>

alt text

ping www.rt-thread.org

After connection, perform throughput test with iperf.
A GUI tool (jperf) is provided under packages/netutils-latest/tools.
- Extract jperf.rar and run the .bat file to launch the tool.
Start iperf test from the board (replace <PC_IP> with actual PC IP):

iperf -c <PC_IP>

Prefer 2.4 GHz network for testing (can use PC hotspot).

Notes

Ensure the Wi-Fi module is correctly connected.
Serial terminal commands allow scanning, joining, and testing Wi-Fi.
