Ardupilot and PX4 in one application

Hi all!
Guys, please tell me. Has anyone implemented the simultaneous use of Ardupilot and PX4 in one application? I have a written mechanism for defining the system, but it changes MAVSDK and I cannot use it with the original MAVSDK. I’m wondering if there are internal MAVSDK tools for this?
Thanks in advance for your answer and good mood! :slight_smile:

Both vehicles talk mavlink, I see no reason why it should not be possible to control a fleet of PX4 and ArduPilot vehicles, provided you only use mavlink messages that are understood by both vehicles, using the same format.

Thank you.
I meant exactly the way to load the mission. As far as I understand from the documentation, it is slightly different. But I could be wrong. Now I’m using mission_row to load the mission into the ardupilot.
