So I will start a new discussion instead of piggy backing on the realflight models discussion. Here is the post regarding this topic in the realflight model discussion.
So I got Cygwin working in windows 10 and have the SITL working with mission planner and can perform auto missions with no issues. I also can start a realflight simulation from mission planner in the simulation tab and have no issue with running an auto mission with realflight handling the dynamics model.
It is only when I build the arducopter software in cygwin or even WSL and connect it to Realflight. I connect into the simulation with MP. Then I try to run an auto mission and I get a failsafe: Terrain data not available. What is strange is that when I first start the simulation, the altitude reading in mission planner is not 0. it is the altitude that I set for the Home position when I started the sim.
Any help with this would be greatly appreciated.
Thanks,
Bill
