Interfacing Pixracer to ROS (mavros) with Telemetry Radio (no wifi)

I successfully connected my Pixracer to mavros over the wifi module on the pixracer, since the connection through wifi wasn’t good (kept disconnecting and connecting) I now use telemetry radios (serial). But I now can’t use "roslaunch mavros px4.launch fcu_url:=“udp://:14540@192.168.1.36:14557"” to connect to mavros. What can I do and How?

Have you tried:
roslaunch mavros px4.launch flu_url:/dev/ttyUSB0:57600

Substitute /dev/ttyUSB) for whatever /dev/tty your serial radios appear as.
Also speed should match your own setting

Previous post had typos, should be:
roslaunch mavros px4.launch fcu_url:=/dev/ttyUSB0:57600

More info here:

Hi. I have the same problem, I haver a telemetry (no wifi) but I can’t run the mavros node. Do you find the solution?

Regards!

When I want to run mavros: roslaunch mavros px4.launch fcu_url: = / dev / ttyUSB0: 57600.

I get the following error:

Roslaunch mavros px4.launch fcu_url: = / dev / ttyUSB0: 57600
