Greetings all
I wrote lua script for drone 1 to yaw towards drone 2 in guarded mode.
It works in mission planner simulator just like I wanted.
But when I deploy the 2 drones outside with gps fix they can not see each other.
Massages:
Yaw Swarm Tracker: Waiting for target
they are both connected to a laptop via USB separately, and I can see both of them in mission planner with the correct sysIDs.
what could be the problem ?
Your help is much appreciated
Most likely this is because Mission Planner isn’t routing the mavlink messages between the USB links. I wasn’t able to determine if this was possible via USB in Mission Planner after a quick google search, but unless you’ve been able to confirm that this works, I would assume it doesn’t.
How did you set up the communication links when testing with SITL?

Thank you for your replay
i used copter single link then type 2 when asked how many drones
Can you share a screenshot of that where you are prompted to enter the number of drones?

after clicking copter swarm single link in mission planner simulator
Can you try connecting to the drones through their telemetry radios to your laptop instead?

I tried and failed that approach. The second drone times out when trying to connect even through its using a different port.
Right now I am trying to use mavproxy for the first time. Both USB com ports are now connected in a single UDP connection which is a good sign.
however, the drones still don’t get the gps location of each other. Even though they are both visible in mission planner with a single UDP connection.
