I've been having ESC arming problems with a couple of ACM versions.
The last two versions I flew, v37 and 42, there was no problem, but with some other versions including the recent v43 not all ESC's arm immediatly. They keep beeping for a while (30-45sec) and then finally arm. Not all ESC's do this. Once they are all armed I have no problems flying.
I think this has something to do with minimum throttle but why don't I have the same problem with for example v42???
What could I change in the code so all ESC arm at once??
They are all calibrated, so thats not the problem.

Confirmed I went back to a older revision(.40) and my ESC's arm properly, using the latest firmware does not arm my ESC's
Ok, I think I found the solution. :-)
When I do an initial calibration in CLI get arround 950 pwm values.
If I do a calibration through MP I get around 1014 and then the ESC keep beeping when powered up.
I lowered the pwm value to 1000 in MP and behold, the ESC's start like they should.
damn, does it again with v48
Problem is gone againwith v 44 and 45.
Strange.
I've seen this once in a while. Mostly it's a low battery, but it goes away on it's own. Nothing in the code has changed regarding PWM.

With ESC arming I mean when you connect the battery.
