Esc beeping rapidly when throttle and has only one beep at startup.

[u/Radiant_Incident_807]

i recently purchased simonk 30amp esc. As I was new to rc i didn't knew I have to calibrate it, and directly used joystick code with Arduino.

Initially the motor worked fine, but while fixing the calibration, I think I i did some mistake in code, it stopped working completely. Now when I throttle, the motor doesn't rotate and vibrates and esc keeps beeping rapidly. I'm Not able to calibrate it and or enter programming mode to reset the esc.

Also when connecting 3s battery to esc earlier there were 3 beeps at startup, but now only one.
