Detailed problem description. How does observed behavior differ from the expected one?
We’ve done frame class and type configuration, compass calibration
,radio control calibration in mission planner, accelerometer calibration in mission planner, and rc transmitter flight mode configuration.
We tried three different methods to calibrate ESCs as follow.
a.I tried the “Calibrate ESCs” in mission planner.
After pressing the button “Calibrate ESCs” in mission planner, ESCs not beeped at first ,and after few seconds ESCs kept beeping unless I disconnect the battery.
b.I tried the " All at once calibration" from http://ardupilot.org/copter/docs/esc-calibration.html
But my ESCs didn’t emit the musical tone and the 3 of beeps and then an additional two beeps.
I raise the throttle and they didn’t spin.
c.I tried the " Manual ESC-by-ESC Calibration" from http://ardupilot.org/copter/docs/esc-calibration.html
It worked. But when I pluged ESC cables back to navio2, I can’t test motors.
Looking at the MP screen copies, Radio settings are out of range for channels 1,2 and 4. So if ESC calibration is well done with direct esc connect to Rx, it is not possible to arm motors with 1274-1781 channel 4 range.
It is indicated in the Mission Planner RC calibration screen. Below 1100 and over 1900.
You have to adjust endpoints of your RC Tx (as you did for channel 3) and redo the Mission planner RC calibration. If you use the channel 3 Tx endpoints setting for channels 1,2 and 4, you are in the expected range.
Is there a suitable version for RPi 2B ? My version on MP of arducopter is 3.6.5.
If I check the version of arducopter directly by "sudo emildtool ardupilot ", It only showed “3.6”. How can I know that the version of MP and Navio2 are the same?
