1. do you have instlled 433MHz RF receiver module? if YES, when download firmware, remove it.
2. Do you have use CHIP= ESP32?

take a photo of your KC868-A16 board. how you wire.

[rodhamesh]

Just 12 volts and USB-C!

[admin]

change your usb-c cable.

I have been using the same USB-C cable for the last few days and it was working. I changed the cable and still the same issue. I think its an issue with ESP32, it just locked or bricked.
