Getting started with the network-socket API
Nucleo-F103RB With W5500 in Mbed Studio

1. Mbed Studio New Program

• Generate Program

2. Build Program

3. Add Library

1) Git-Hub Download

• Add easy_connect Library easy_connect
  git clone or Download Zip

• Wiznet-eth-driver Wiznet-eth-driver
  git clone or Download Zip

- Add Liberary in Active Program

2) Mbed Commend

• Copy file easy-connect.lib mbed-os-example-sockets_Nucleo-F103RB_W5500
• Add easy_connect Library
  Commend : mbed deploy https://github.com/WIZnet-MbedEthernet/easy-connect.git

• Wiznet-eth-driver
  Commend : mbed deploy https://github.com/WIZnet-MbedEthernet/wiznet-eth-driver.git

4. modify mbed_app.json file

        "NUCLEO_F103RB": {
            "esp8266-tx": "D8",
            "esp8266-rx": "D2"
        }
    }
}

5. modify targets.json file if using Nucleo_F103RB

Nucleo_F103RB not support LSE and must define LSI.

After Build Program, check define LSE

6. Run Program

7. Result

Note: The default serial port baud rate is 115200 bit/s.
