Multiple Interface example

Overview

This example demonstrates working with multiple different interfaces with different priorities. It creates these interfaces and tries to connect:

• WiFi Station
• Ethernet using ESP32 internal ethernet driver
• PPPoS over cellular modem

How to use example

• Set the priorities and the host name for the example to ICMP ping.
• The example will initialize all interfaces
• The example will start looping and checking connectivity to the host name
  • It prints the default interface and ping output
  • It tries to reconfigure DNS server if host name resolution fails
  • It tries to manually change the default interface if connection fails

Hardware Required

To run this example, it's recommended that you have an official ESP32 Ethernet development board - ESP32-Ethernet-Kit. You would also need a modem connected to the board using UART interface.
