I have read various pages (RTL Mode (Return To Launch), …)
but the correct selection of a remote HOME position is still unclear to me
(PLAN: WP?, AUTO WP?, Rally Point not found!).
When I switch to RTL, I want the model to immediately return to a fixed point
across the runway and circle there with a certain radius (no landing, altitude
is not important). This position should be saved forever in the F405.
Furthermore, it is not clear in (GPS dependent mode) (unplug?).
Thanks for checking. I looked at the enabled features for that very board before replying above. The MavLink Rally Point feature was enabled, but the HAL ChibiOS Rally Point feature showed disabled. I guess one of the two is enough!
