How to make a swarm

I’m working on a project to make a swarm of 3 quadcopter. But as soon as I connect the 2nd Quadcopter the Mavlink message lost reaches above 90%. How can I eliminate this problem?

I think i can help you
Please send me a message

@Muhammad_Usman Does the two vehicles have different system IDs?

You probably need to update your data link to a faster one or reduce the amount of data shared.

Yes both vehicles have different system IDs and both radio telemetries pair have different net IDs. But the MAVLink loss rate is always above 50% after i connect 2 vehicles.

How can i do that. Could you tell me the step or a link.

Hello Usman, Would you mind sharing the project details ?
