    Hi Eric, the demo code of python can work with mavsdk_server,
    but C++ demo code can't connect with mavsdk_server.
    I read source code of python that assigns udp port for mavsdk_server.
    C++ demo code doesn't assign udp port for mavsdk_server.
    Does this cause C++ demo code doesn't work?

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

            @CY-1992 I generate libmavsdk.so from instruction of mavsdk.mavlink.io,
            but it can't be compatible with VOXL.
            Do you know where I can get source to generate libmavsdk.so for VOXL flight Deck?

              I assume you have seen this tutorial since you mention the docker image

              Have you tried to upgrade cmake inside the voxl-mavsdk-cpp:v1.0 docker? If cmake version is the only blocker, you should be able to upgrade it to keep moving

                  @Chad-Sweet Maybe you can offer the right version of mavsdk source. Because I use "git clone https://github.com/mavlink/MAVSDK.git". It's too new to be compatible with VOXL flight Deck.

                    @PIRON-PI You don't need to build mavsdk from the source if you are using it in docker on voxl. Just download the arm64 deb package and install it in the docker as shown below in Dockerfile. Try to use base image arm64v8/ubuntu:20.04. It has the latest cmake version.

                    FROM arm64v8/ubuntu:20.04
                    ENV DEBIAN_FRONTEND noninteractive
                    RUN apt-get -y update && \
                        apt-get install -y build-essential cmake git wget
                    
                    WORKDIR /home
                    RUN wget https://github.com/mavlink/MAVSDK/releases/download/v1.4.0/libmavsdk-dev_1.4.0_debian11_arm64.deb && \
                        dpkg -i libmavsdk-dev_1.4.0_debian11_arm64.deb
                    
                    WORKDIR /home
                    #copy all your c++ files and CMakeLists.txt to home directory
                    COPY . .
                    
                    RUN cmake -Bbuild -DCMAKE_BUILD_TYPE=Debug -H. && \
                        cmake --build build -j4

                      @chaitanya Sorry. My goal is that cell phone can control VOXL flight deck.
                      Therefore, I need a MAVSDK library( e.g. libmavsdk.so) at Android. Then I can use the library to send command to control VOXL flight deck.
