Morgan Du / Mbed OS Serial-to-Ethernet

Transfer data between UART ports and Ethernet.

Dependencies:   BufferedSerial

Transfer data between UART ports and Ethernet.

  • Support multiple UART ports.
  • Support fixed IP address and DHCP.
  • Support TCP server and TCP client modes.
  • Support a simple web server for UART and Ethernet configuration.
