Shall remote controller be always on? #14

We noticed hl_interface only works if the RC is on and the serial switch is on. Otherwise the messages and service calls do not work. My concern is about outdoor applications where the RC signal does not reach the mav. Is there a workaround for this?

This is actually intended behaviour, since there should be ALWAYS a safety pilot, who can take over in case of a failure or at least shut down the helicopter. The RC signal usually reaches further than line of sight, so you will run into legal issues before actually losing RC signal ;) .

Service calls and messages should still work, but the LLP won’t listen to any commands in case the serial switch is off.

However, well, presented in that way I think the issue I raised is not a real issue :P

Howver, if I wanted to go ahead and avoid the use of a safety pilot, would that be possible? Should I modify the firmware?

markusachtelik commented 10 years ago

you can't do that in the HLP firmware ... it would require some bad hacking with the LLP.

Ok, thank you...low priority so far ;)
