Serial passthrough using WIZwiki-W7500 and gainspan-WiFi-module

Description:

I can issue at-command-sets to the WiFi module with WIZwiki-W7500’s serial.

Here is a capture of test logs. The red box is what I issued.

Connected pins between WIZwiki-W7500 and WiFi-module are only 4 pins. (3.3V, GND, UART-Tx, UART-Rx)

UART data flow is shown as below.
