Hi, im about to update the firmware of arducopter from 3.3.3 to 3.6.4
I have the full parameter settings of 3.6.4 saved in a file
My question is that do i have to load the settings before i do a compass calibration and a motor/compasss calibration?
cause if i load the settings file after the calibration procedures wont the offset values overright?
Just backup the parameter values from your 3.3.3 version for the case something goes terribly wrong.
And update the FW after that. the FW update will retain as many of the parameter values as possible.
It might be that you do not even need to recalibrate.
I do not recommend that you load the old, outdated 3.3.3 parameter file in a newer firmware.
Thanks. But how do i know that i might not need to recalibrate?
If it arms, and flies, then you do not need to re-calibrate.
If you do not want to take any risks, re-calibrate.
