@marian Try to use base image arm64v8/ubuntu:20.04 in Dockerfile. It has the latest cmake version.

FROM arm64v8/ubuntu:20.04

@PIRON-PI You don't need mavsdk-server if you use C++.

@Eric-Katzfey Based the docs, I thought multiple UDP connections can be established with voxl-vision-px4

Hi,
I am using MAVSDK python and pymavlink in my project. I used the following code

await drone.connect(system_address= "udp://:14551" )
mavutil.mavlink_connection('udpin:0.0.0.0:14551')

It throws an error "address is already in use". Can two local processes simultaneously have access to PX4 via the same port 14551?. The documentation shows voxl supports up to 16 simultaneous UDP connections.
