One question:
sometimes we are not able to Activate to drone and request control with no possibility to check after dji_sdk/activation
How we can be SURE the system is activated or not? Which parameter can we check?
Could we be sure that activation is ok when dji_sdk/activation return 1?
Another question:
We want to use M600Pro without RC. Is that possibile with A3 in M600Pro and OSDK updated at the last version possible. How can we do to fly without RC?
dji_sdk/activation is a service in ROS. I don't think you can get activation state this way. If the drone has not been activated successfully, the dji_sdk node will not be launched. I think the activation state is very easy to obtain.
