Hello,
we have an octocopter setup with 2 F55A 4in1 ESC´s and used these instructions to connect it to the cube:
http://ardupilot.org/copter/docs/common-dshot.html
We can´t use d-shot, because of the 8 Motors, so we connected it to servo outputs, but passthrough should still work. We used die Serial 5 port for this, like it is described in the wiki. But the BLhelisuite32 does not connect, sometimes there was an about reboot our power up ESC.
Has somebody tried a 4in1 ESC or has any tips on this subject?
best regards
christian
