It can be connected to PC or MCU through various network interfaces (USB/SPI/SDIO). ESP32 series chips use NAT to forward data packets in and out of the Ethernet network interface. <img src="https://raw.githubusercontent.com/espressif/esp-iot-bridge/master/components/iot_bridge/docs/_static/wired_nic_en.png" style="zoom:80%;" /> ### How to use example #### Hardware Required **Required** - An Ethernet cable - An esp32 series development board - A Micro-USB cable for power supply and programming **Optional** - A USB cable for communication - Some DuPont cables to connect to the SPI or SDIO interface of the MCU Follow detailed instructions provided specifically for this example. #### Choose the interface used to provide network data forwarding for other devices You can select the interface (USB/SPI/SDIO) connected to the PC/MCU in `Component config → Bridge Configuration → The interface used to provide network data forwarding for other devices` of `menuconfig`. #### Build and Flash Run `idf.py flash monitor` to build, flash and monitor the project. Once a complete flash process has been performed, you can use `idf.py app-flash monitor` to reduce the flash time. (To exit the serial monitor, type `Ctrl-]`. Please reset the development board f you cannot exit the monitor.)
