TL;DR — How can I communicate with my APM 2.5 in a HIL simulation FROM A DIFFERENT COMPUTER using the 3DR radio (wireless telemetry interface)???
I noticed here that I "cannot connect via the radios when [my] APM 2 is also connected via USB [because] they share the same port"... and to use the APM 2.5 in a harware-in-the-loop (HIL) configuration, I must be connected via USB (right??)... so:
HOW can I communicate via 3DR radio with my APM 2.5 in a HIL (connected via USB) if they use the same COM port?
I want to use the APM 2.5 in a HIL simulator (FlightGear) because I do not have an airframe... and I want to "control" the APM 2.5 from a DIFFERENT system than it is using for the HIL...
Any suggestions on how to accomplish this???
