Blue esc blinking 1, 2, 3


We are having a problem initializing our escs. When we send power and a pwm signal to them, only a few initialize and run the program. The others do not beep but instantly start blinking red in a 1, 2, 3 sequence. What does this sequence tell us.



This is in line with some issues we’ve been having with a few batches of BlueESCs. If you don’t mind, please send me an email at and we can discuss how to resolve it. We’ll get it figured out quickly.




I emailed you.
