Publishing mavros/rc/in topic to mavros_msgs/RCIn #1149

Open TK1109 opened 5 years ago

TK1109 commented 5 years ago

Hello,

I am trying to get mavros/rc/in to be published as a message: mavros_msg/RCIn I have entered the following into a terminal window: $rostopic echo /mavros/rc/in | rostopic pub bar mavros_msgs/RCIn

Ultimately I want to be able to read the channel values as they change with input in MATLAB.

However, when I look in MATLAB to see if the information can be read or not, it appears that no new information is read by MATLAB from the mavros_msgs/RCIn

I am I entering the publish command line correctly? Is there a way to verify in ROS that the message is publishing? I am quite new to ROS and I am having trouble navigating this issue.

Thanks!

I don't know matlab, but perhaps you mess with topic type (mavros/RCIn) and topic name? Matlab code looks like you create new empty RCIn massage (struct/class) and print it (new message are zeroed).

And why you need to republish topic? Maybe easier just remap it?

Oh, also you can use RQT to watch what topics exists and what data is published.
