It would be great if we could do a follow up for those of use that want to use a Raspberry Pi companion with a Pixhawk, and learn how to send DK script to the Pixhawk just like we do with the SITL. Also use the companion for CV/precision landing and adding other custom off-board (I2C) sensor devices as discussed in the PL course. All this would greatly expand the capability of the Pixhawk. The board is widely used, so I think there would be a lot of added interest.
Also, would like to learn how to directly interact with the Pixhawk code and what we can do with that knowledge.
Also what is MAVSDK and is it an alternative to DK? What are commercial operators using to run their missions?
