@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.

@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.

@Chad-Sweet I try to upgrade cmake in docker, but it doesn't work.

@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?

@CY-1992 You give me confidence .
I did it.
Thanks a lot.

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?

Hi, I download a new version of mavsdk.
But New mavsdk needs cmake version 3.13 or later.
I try to use voxl-emulator or gcr.io/modalai-public/voxl-mavsdk-cpp:v1.0, but their cmake are too old.
Is there a way to build new version of mavsdk?

@沈-宏澤 Do you solve your problem?
How to solve it?

Hi, My device is VOXL FLIGHT DECK.
I can use RC to control my device.
Now, I'd like to use offboard mode.
First, I key in "docker run -it --rm --privileged --net=host gcr.io/modalai-public/voxl-mavsdk-cpp:v1.0 /bin/bash"
Second, Type "./takeoff_and_land udp://:14551"
And then Show following message.
At bottom, It keeps saying "Vehicle is getting ready to arm"
What steps do I miss?

@Eric-Katzfey I can see color video by using voxl-streamer -c hires-logo.
Thank you.
