With LAN you have exactly the same as with WiFi, the only limitation is the free Gpio's.

Hello,
I tried using library for LAN8720 (built in SuplaDevice, I assume that's the same one).

It doesn't work in my case. ESP shows such an error on Serial:

Code: Select all

E (124857) esp_netif_lwip: esp_netif_new: Failed to configure netif with config=0x3ffb2610 (config or if_key is NULL or duplicate key)
E (124867) esp.emac: esp_eth_mac_new_esp32(595): alloc emac interrupt failed
@elmaya there are more details in PM.

Regards,
Jakub
