I recently put together a quad using a Pixhawk 2.1 and 3.5.5. Got everything going without many problems. Specifically, that quad has ZTW opto ESCs with the red wire connected.
So I’m putting together the same frame and motors with another Pixhawk 2.1, but with HobbyWing Platinum 30A opto ESCs. Now the FC that came off the frame was a Naza and the HobbyWings did not have the red servo wire.
I also have a hexa with the HobbyWings and a Tarot ZYX-M FC and it does not have the red wires either. Both the Naza and Tarot worked fine.
With the subject quad, when I power it up, all I get from the ESCs is the beep indicating they’re not connected or receiving a signal from the FC. I’ve tried adjusting the MIN and MAX MOT_ parameters, tried calibrating the ESCs individually for throttle travel, double checked the wiring. Nothing is getting me going.
Has anyone run into this issue with 3.5.5/PIxhawk2.1 and these ESCs? I’d like to nail it down before I do a complete disassembly to solder in the red ESC wires.
On a separate subject, the Here GPS shows the flashing arm button, but no other LED status indications. My OSD is telling me the GPS has position though
