The transmitter handset / manual controller. It will sing the song of its people for connection to the drone (and the drone LEDs stop blinking / go steady-on), and the transmitter and drone both know when the other has powered off / lost connection, because they react normally to those events. But pressing up on the left thumb stick does nothing.
arducopter-2017-11-24.abin. I tried dropping it in the root of the SD card, but it didn’t seem to do anything with it. I booted it up again and tried to connect with the Sky Viper app, and it complained about the controller/transmitter not being connected (the drone’s LEDs disagree), then wanted to do the firmware dance. IE, there was no change in behavior.
Thanks for the tip! I couldn’t find a tutorial on building firmware from source files into an abin file; is there one you know of? Otherwise, I’ll keep looking in the developer section.
Thank you for your help!
