Notes on programming
If the LED on your CW01 has the following colours:
Faint GREEN
Very faint RED
No BLUE
... then it means that your CW01 is in programming mode.
To make sure that it automatically starts your program after programming and is not stuck
in programming mode, program/flash your CW01 by choosing "DIO" in the Arduino IDE.
The memory on the CW01 is 4Mb, you can choose any of the 4Mb options in the Arduino
IDE, with the size of SPIFFS that fits your project.
