Connecting two KC868-A8 together

[msinfo]

Hello, i have a strange case here. I am running ESPhome with the KC868-A8 board with Ethernet and i want to use a second KC868 board. On the second board the ethernet port is not working and i don't have access to a WiFi signal. Is there a way to communicate with the first board and send and receive data without connecting it to wifi or ethernet ?

Thanks

i think you can try go fix ethenret or wifi, find out why it can't work, maybe you can re solder LAN8720 ethernet chip. but the wifi work with ESP32 self, maybe you can check with ESPHome config yaml.

Wifi isn't an option. And i tried to resolder the chip but i don't have the right tools and it didn't work.

what software you are using? home assistant?

Yes, i'm using Home Assistant.

why you not config wifi ssid and password in ESPHome , just use wifi connect to router.

I don't have a wifi signal. The board is in my basement and there is no signal there.

I bought i new KC868-A8 i'll just use it instead. I'm going to put the old one somewhere else.

Thanks.

maybe you can use it by i2c bus. But not suggest to use by this way.
