RP2040 wifi HTTP client (use wizfi360+micropython)

How to Test HTTP Request Example

Step 1: Prepare software

The following Python IDE program is required for http_request example test, download and install from below link.

• Thonny

Before programming, see the following videos and Getting Started.

Step 2: Prepare hardware

If you are using Wizfi360-EVB-Pico, you can skip '1. Combine...'

Combine Wizfi360 with Raspberry Pi Pico.

1. Combine Wizfi360 with Raspberry Pi Pico.

2. Prepare AP Modem which is connected to Raspberry Pi Pico or Wizfi360-EVB-Pico.

3. Connect Raspberry Pi Pico or Wizfi360-EVB-Pico to desktop or laptop using 5 pin micro USB cable.

Step 3: Setup HTTP Request Example

To test the HTTP Request example, minor settings shuld be done in code.

• Setup AP Modem configuration such as SSID, Password in 'secrets.py' which is the secret settings file in '/lib' directory.

secrets = {
    # Wi-Fi
    "ssid": "my access point",
    "password": "my password",
}

• Setup UART port and pin in 'http_request.py' in 'examples/http/request' directory. (Wizfi360-EVB-Pico Using Uart1, Rxpin5, Txpin4)

PORT =1
RX   =5
TX   =4

also, setup the Reset pin at the next line (Wizfi360-EVB-Pico Using ResetPin20)

resetpin = 20

• Setup Http URL. You should set the required URL in 'http_request.py'file.

URL="http://httpbin.org/get"

Step 4: Upload and Run

After completing the code example configuration, open 'http_request.py' file on Thonny,

Click the 'RUN' button on bar or press the 'F5' button on the keyboard to Run program.

If the HTTP Request example works normally on Raspberry Pi Pico or Wizfi360-EVB-Pico, you can see the messages received from the URL.
