moveBy not working

[perevalovds]

Hi! I add function to Bybop_Device but calling it after take off causes no effect at drone side and not responding on another commands at PC side. That's can be a problem?
(without calling it, I call take_off and land without problems)

def moveBy(self, dx, dy, dz, rotate_rad):
"""
Move the drone to a relative position. The drone will move of the given offsets.
"""
print("moveBy",dx,dy,dz,rotate_rad)
self.send_data('ardrone3.Piloting.moveBy', dx, dy, dz, rotate_rad)
