Please, I will like to know the difference between these topics.
Under what condition will you use OverrideRCIn message on /mavros/rc/override to change channels that are published on /mavros/rc/in?
Under what conditions is it advisable to publish to /mavros/rc/out? In what way can I change the value published to /mavros/rc/out.
I realized that by default (after starting apm.service), /mavros/rc/in has 0 on all channels while /mavros/rc/out has 1500 on all channels.
In my project, I need to use ErleBrain3 to autonomously use its heading and GPS readings to explore an environment. So far, I am able to publish and change values on /mavros/rc/in topic, however, the Traxxas Summit rover does not respond to any value I published on this topic (tried values from 500 to 2000).
After going through the list of topics again, I feel I may have to publish on /mavros/rc/out instead. But I don't know how to do it, and whether this is the right thing to do.
