@robski said in M5CoreS3: "ERROR Device type unknown" when trying to connect both CoreS3 and CoreS3 SE to Server.:
@PhilB79 you have to use M5Burner when loogged in so firmware update "binds" your device in to your uiflow account and then it is visible on the list if connected to internet.
Yes I use the full process of Erase, Bind and Burn. Tried many time but still the Red dot in device select.
I'm about to give up and put the lot in the bin and go back to ESP32s
