  • I loaded the 2.7.1 HIL firmware on my APM 2.0 for testing with FlightGear. However, I could not connect to the APM from the Mission Planner. I reloaded the Hexa firmware and verified that I could connect. Then re-loaded the HIL firmware to verify that I still could not connect to it with this firmware loaded. Any ideas?

  • Thanks for posting, and for all of the hard work Andreas, as well as all of the developers. I have a few questions regarding Limits (i.e. GeoFence) I love the idea of bounce mode. Can I enable/disable it with a switch - let's say channel 8? Also, can I abort an RTL after a fence breach by momentarily turning off limits and then right back on again? My thought was to do this with a mix of the enable switch and another momentary switch on the radio, and of course on the enable channel 7.

    Most GeoFence parameters seem to be either grayed-out or ineffective in the GUI in the mission planner since it's V1.2 release. Is it my installation or is this a real bug?

  • hi all.

  • APM1. Camera gimbal is not working. The Pitch and Roll axes not correctly work.

  • So what is meant by "sensor-fusion"?

  • T3

    How do I implement crosstrack, is it CLI only?  It is grayed out on the config screen.

  • Does this address the wobble in loiter mode...........Don

  • Very Cool I will try to test this afternoon

    Thanks, Andreas! It's in the Mission Planner now.
