mavros node on base station fcu_url
I usually connect my QGroundControl (running on base station) to the voxl which in my unsderstanding "routes" the mavlink data from the flight core to my base station.
Sometimes I want to run a mavros instance not on the voxl but on my base station. I am not sure how to configure this node correctly in order to connect to the flight core using voxl as "wifi link". It works if I set the
fcu_urlparam like that:
udp://:14550:@VOXL_IP:14556but then the link in my QGroundControl fails. I guess it is because both connections are running over port
14550. I have no idea how to set
fcu_urland gcs_url`. Or do I have to install additional software on the voxl to route the packages?
Any help would be appreciated!
Hi Rapit, have you looked at this doc here?
I think you'll want to look at this parameter "en_secondary_qgc"
thank you for the link. I did read section before but I could't see how it would help me as the port on the outgoing connection is still the same.
I just configured my base station ip in
en_secondary_qgc) and the connection to my ground control station is successfully initiated by voxl. But when I fire up mavros at my ground station, QGroundControl again loses the connection to voxl, so initiating "from the other direction" does not seem to solve the port conflict.
You don't need the secondary qgc_ip, just one udp link from VOXL to MAVROS. In this case you would use MAVROS as another link in the chain between VOXL and QGC.
VOXL <--> MAVROS <--> QGC
Try launching mavros with the fcu_url :
You may need to change the port to QGC to something else (like 14551) to avoid a conflict.
Thank you, it works now. I did not think about using my local mavros as connection link between voxl and QGroundControl.
I changed the port. The original issue was a binary installed mavros which crashed when using a
gcs_url. So I thought it was a configuration problem but building mavros from source and running with your proposed configuration worked. Thank you again!
