It seems that there is a small issue with the ESC calibration on version 3.5.6:
When BRD_SAFETYOPTION = 3, the ESC calibration is not working as described in “All at once calibration” section on this page : http://ardupilot.org/copter/docs/esc-calibration.html
When pressing the safety button, it doesn’t becomes solid red but continues to blink and the ESC’s are not calibrating.
To bypass this we need to set the BRD_SAFETYOPTION = 7, proceed with the ESC calibration, and then set it back to BRD_SAFETYOPTION = 3
Could I ask you to test Copter-3.5.7-rc1 and report back whether the ESC calibration is working for you or not? I’ve tested it so I’m pretty sure it works but it would be nice to have at least one other person test it.
Hi Randy,
I confirm that ESC calibration works again as it should in version 3.5.7-rc1.
It was tested with the “All at once calibration” procedure (as explained in page : http://ardupilot.org/copter/docs/esc-calibration.html) and also with the “ESC calibration” menu in MP and.
Thank you for the correction.
I not 100% esc calibration is working right I not getting the rotating sounds like the old version only sounds like one esc is working/beeping. I miss the full consort of tones. Could be just my ZTW esc’s not sounding off.
No, it doesn’t. There’s a de-bounce added to the auxiliary switches in Copter-3.6 but still, if the pilot demands a disarm from an auxiliary switch, it always obeys.
