Companion IP addresses

Hi @Seb,

Sounds like a useful and interesting setup!

If you want to run separate instances of QGroundControl on the same subnet (192.168.2.x) then you’ll need to change the telemetry port for one of them (and the device that’s sending to it). I discussed that and another alternative in some detail in this comment.

Here’s a diagram that Blue Robotics created. It helps with understanding how information is exchanged between the Pixhawk, the Raspberry Pi, and the surface laptop.

@CBW3750 that diagram is quite outdated - there’s now an up-to-date and interactive version of it in our docs: Software Components · GitBook

For a system like this I would choose to utilize two sets of tethers and Fathom Interface boards, instead of one set.

That would also work, but an extra set of tethers and Fathom-X boards isn’t required for the desired functionality, so would be an unnecessary expense in this case.
