Mavlink commands with Wiris Security

[Tiberius F.]

Hello, I have a project in which I connect a Wiris Security camera with a transmission system. I want to say I don't connect this system with a autopilot. So, I control the camera with MAVLink. I realised a script with which I connected the camera, but I don't know how to send a command or receive a message.

I attached the code and the pictures with commands which I want to implement.

If I send the message MAV_CMD_REQUEST_CAMERA_CAPTURE_STATUS, I receive the error AttributeError: 'int' object has no attribute 'pack'

If I send the message MAV_CMD_DO_DIGICAM_CONFIGURE(1,0,0,0,0,0,0), I receive the error TypeError: 'int' object is not callable.

So...Can somebody help me with this problem and explain me how to send commands to control the camera?

The best place to ask this question is on the pymavlink gitter  channel: https://gitter.im/ArduPilot/pymavlink

I'm not very familiar with Pymavlink, but what you're sending is a command. So you need to pack it in a Command_long or command_int message and then send that message. A good example from a quick net search is this one: https://williangalvani.github.io/ardusub-gitbook/developers/pymavlink.html#armdisarm-the-vehicle

master.mav.command_long_send( master.target_system, master.target_component, mavutil.mavlink.MAV_CMD_COMPONENT_ARM_DISARM, 0, 1, 0, 0, 0, 0, 0, 0)

Hope that is enough to get you started

I was able to connect and control the camera through a transmission system. Indeed, I had to pack everything with the command_long command. Thanks a lot for the information and if anyone wants the code, I can display it here
