Step 1: Prepare software

The following program is required for Tcp Client example test, download and install from below link.

• Thonny
• Hercules

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.

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

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

Step 3: Setup Tcp Client Example

To test the Tcp Client 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 'tcpclient.py' in 'examples/tcp/client' 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 TCP server IP and PORT to suit your network environment. You should set the required informaion in 'tcpclient.py'file.

TARGET_IP = "192.168.11.100"
TARGET_PORT = 5000

Step 4: Upload and Run

Open Tcp server using Hercules. You need to enter the port that was configured in Step 3. (5000 by default)

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

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

 

You send data to the tcp. every 60 sec
