Flight mode does not change after entering "return to launch" mode

[kennethakiti1]

I'm currently using the jetson nano with the mavsdk_server. I'm able to get the drone to go on missions etc, but whenever I initiate a return to launch command, the flight mode gets stuck in this mode and unable to take other new commands such as "takeoff", "kill", "begin_mission" etc unless I use the RC controller to switch the mode before it can begin another action.

when I checked the health, it shows it is not armable, but I don't understand how "return to launch" deactivates its armability

is there a way to set the flight mode, let's say from "return to launch" to stabilized mode or another mode?

Are you trying to change the flight mode when it's still flying or once landed and disarmed?

You can set flight modes like this:

• mission->start() for mission mode
• mission->pause() for hold mode
• manual_control->start_position_control() for position control
• manual_control->start_altitude_control() for altitude control

I am trying to change the flight mode once it's landed and disarmed.

Actually, I don't have much interest in changing the flight mode, but since after landing and disarming it gets stuck in the "RETURN_TO_LAUNCH" mode, I need to find a way of changing the mode withing needing the remote controller.

It should still let you change the flight mode once landed. Do you see any errors when you try to change it? E.g. status text messages or messages in QGC?
