Old noob, working with pre-built blue-arduplane, learning by doing and reading and troubleshooting. I’m a year into my custom project.
This craft is based on a twin-engine delta-wing elevon architecture, but specialized for a low-speed, long range research application. Using both Mission Planner and QGroundControl: I’ve got working GPS and telemetry reporting via 3DR 915MHz to my laptop GCS. Since this is a low-speed craft (RC response time is not so important) with a tight energy budget, * I want to control the craft using the telemetry radio and setup a HOTAS joystick to my GCS*. After much head-banging, reading about ArduPilot code, BB books, plumbing various forums, getting acquainted with Linux and a lot of hands-on monkeying around, it seems I’m still short on a real understanding of configuring the BBBL pins and/or blue-ardupilot parameters, as I’ve yet to get a response from my craft's servos or motors. Peripherally, but perhaps informative to this problem, I took a whack at interpreting the *blue-arducopter* startup-on-boot instructions for blue-arduplane and tried integrating Mirko's added instruction note regrading turning-on the servo rail, but using the *systemd *approach, as in the attached file. It's not clear that creating and modifying those files had any effect, but ultimately what I generated did not result in auto-startup of blue-arduplane. Anyway, I’ve gone through the joystick calibration procedure in Mission Planner and QGC but I get no associated response from the BBBL. When I enable the joystick and try to arm the (propeller-less) craft, in MP I get the message that MAVlink has rejected the command. QGC reports that this control-via-telemetry is a non-default behavior, seeming to suggest that the functionality needs to be set and compiled in MAVlink. Have I reached the point where in fact I do have to delve into the code base and compile my own, or is this just a system startup configuration issue (systemd?) or a blue-arduplane parameter switch? It's been a long road, and I'll push ahead, but I'm not as young as I used to be. I'd humbly appreciate a road map (advice) so I don't waste a lot of time on this hurdle.
