I’m trying to test resume mission in QGC (v3.5.2) on SITL simulation. I create a survey and start the mission and in the middle of it i perform RTL, then i land manually, after that i close the MAVProxy which results in communication lost with the QGC like when i’m changing the battery, after that i reopen the MAVProxy and QGC reconnects to the drone, but there is no resume mission option as is described here, all i get is starting the mission from the binning. how could i fix that ?
You are looking at out of date docs for an old release. Current Resume Mission behavior is shown here: https://docs.qgroundcontrol.com/en/FlyView/FlyView.html. That will only show up after you disarm the vehicle.
