IoT Gateway : W5500 + Raspberry Pi Pico + WizFi360

W5500 which connect ethernet send MQTT to Amazon Web Service IoT. WiFi(WizFi360) Access Point (Server) support Wireless path to IoT Device.

HW Construction

WizFi360 for Access Point + Raspberry Pi Pico (Gateway application) + W5500 for Ethernet + Serial Interface(Log and Command)

Details on W5500 and WizFi360 PIN Connection

TDX and RDX jumpers from the WizFi to send UART data to the UART W5500-EVB-Pico pins.

Test: TCP Client Application

Mobile phone's TCP Client Test application is used for Server Test.

Normally client try to connect server and server accepted client's connection request. And client send data and receive ACK response.

 

Test: Serial AT Command and Response

You can see Command(Request) and Response Access Point and Station.

 

Test: AWS IoT Result

Server(WizFi360) transfer client data to ethernet(W5500) to send AWS IoT Cloud. AWS normally subscribe client data by MQTT.

Result: Serial Logs

Details on how Ethernet and WiFi to run.
