Trivial example for motion module not working

[sigge]

This simple example return a zero-vector, ie. no values for for the gravity (returns (0.0, 0.0, 0.0)). Why?

Running on iPad Pro 2019.

import motion

def main():
    motion.start_updates()

    mf = motion.get_gravity()
    print(mf)

    motion.stop_updates()
    
    
if __name__ == '__main__':
    main()

Insering a sleep for a few hundred ms seems to work. Resolved!
