Hi everyone,
I have the error with the Arduino D1 R1 board with chip ESP8266EX. Everything is ok while compiling and uploading, there are no errors, but when I upload it, it does nothing. It just writes "⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮" in serial monitor, and nothing else. Here is the upload log:

I think that the error is in this: There is the line "Changing baud rate to 460800", even if I set the Serial.begin to 115200. Everything worked perfectly until today. I hope someone can help me.
