ROS(in Jetson Nano) - Durandal

Hi guys, I am checking connection is right or not. And there is a some warnings in terminal. But I dunno is that a big and important or not. And also I cannot see outputs of some of the rostopics when I made echo. Actually ROS do not send any data or something TO Ardu. And I did connection with USB to TTL (Durandal’s TELEM2 port to Nano’s usb port)

If is there any, could you give me an idea to fix it?
Here is my terminal outputs:

~$ roslaunch mavros apm.launch fcu_url:=/dev/ttyUSB0:921600

but I cannot get the /mavros/to topic or some of the topics doesn’t give me any outputs and some of them gave me like /mavros/imu/data topic. . Do I have to write some code like do arm or sth to see the datas sending from ROS to controller? Also I didn’t add any connection to my controller like sensors,esc or sth. That’s why I am not able to see the ESC status topic’s outputs in ROS side but I am not sure. Is there any idiea for that , what am I doing wrong?

I just wait forever for these topics and the others I add these tw just an example.
nothing appears when I run:
~$ rostopic echo /mavros/esc_info
~$ rostopic echo /mavros/mag_calibration/status

Briefly, If I am right, I have to write some program to see /mavros/to topic outputs, but I don’t have an idea for non-visible topics outputs.
Last part of my question is about Lidar, I am gonna use TFmim Plus and I am planning to connect to my Jetson Nano, I got then ROS package from github and I am planninf to use that package but two days later I saw distance_sensor code from mavros_extras folder, so I got confused, Can I use distance_sensor file for TF mini Plus or do I have to add ROS package for that?

Thanks in advance and spending time fot that issue.
Have a nice day!

Hey @tugbakara ,

Did you end up solving this issue? I’m encountering the same errors and can’t work it out…
