Getting Started

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.
