Hello,

i added two new mavlink messages but i have problems sending an response back.
coraldrone get status gets printed to the console, but i get no output back on my c test program
so the message does not get send back to my program.
any ideas on this?

thanks
greetings
andre

hal.console->printf(“coraldrone get status\n”);

    struct Location drone_position_current_loc;

    ahrs.get_position(drone_position_current_loc); // return value ignored; we send stale data

    Vector3f vel;
    if (!ahrs.get_velocity_NED(vel)) {
        vel.zero();
    }

    char active[1];
