How to use MPU9250 with mit app inventor

Hi I want to use MPU9250(or MO6050) with mit app imventor where if I receive the correct yaw roll and pitch then an image moves. Which is like for an exercise. Im confused do i need an extension for it? And how do I send the yaw pitch and roll in a way that the mit app inventor understands them and separates them? I want to use HC05. And in case the user doesnt move in the way intended in the exercise then the image doesnt move but waits for right update.

Also what blocks i need to use to read the yaw pitch and roll. ( I cant use the phones accelerometers because the project is a bracelet)
