One mavsdk_server, multiple drones

[ShafSpecs]

Hello, I wanted to ask if it's possible to have one mavsdk server instance connected to multiple drones? For example, I have three drones bound to one serial usb that I can then differentiate their messages via ids. Can I use one mavsdk server to connect to all three, or do I have to run three different server instances?

mavsdk_server -p 50051 serial://com7:56000

mavsdk_server -p 50052 serial://com7:56000

mavsdk_server -p 50053 serial://com7:56000

No that won't work. You should somehow find a way to demultiplex the serial stream and send the messages to their respective mavsdk_server instance.

I don't think mavlink-router can do that, but maybe you can write your own proxy that would receive MAVLink on serial://com7:56000, detect the different drones (I assume they have a different sysid) and forward e.g. to different UDP ports (e.g. 14550, 14551, 14552). Such that then you could run mavsdk_server instances on udp://:14550, udp://:14551, udp://:14552.

Okay. Thanks, would read up on that 👍
