bool flyMS::wait_for_start_signal()

,

Returns:: 0 on success, -1 if the EXITING status was set Blocks execution until either: 1. the start signal is received from the dsm controller, or 2. something calls “rc_set_state(EXITING)” The start signal is three toggles of the kill switch, then left to the ON position

Returns:: false if the EXITING status was set or an error occurred

static constexpr bool flyMS::kDEBUG_MODE = false: Defines the global constexpr variable kDEBUG_MODE that enables/disables debugging features. If used in an if constexpr statement, the compiler will optimize out the code block if kDEBUG_MODE is false leaving no runtime overhead in the production binary.
