Error 31311 (I2C communication) after NFC setup
Directly after transmitting WiFi credentials to my newly built Core One, the display turned orange and showed an "I2C send failed" error. After confirming the message, it went away and the printer seems to work normally. (I repeated a full self-test cycle.)
The error message included a QR code and link to prusa.io/31311, but that page does not exist yet. Has anyone come across that error as well? Just some firmware glitch in the communication with the NFC chip maybe?

Same issue with the exact same situation for me.
Decided to enter the WIFI credentials manually afterwards and ignored the NFC function for now.

Same for me

Thank you both; looks like a firmware glitch then. Since NFC does not have any further use after the initual Wifi setup, I guess this can be ignored for now
