I am creating a tracking project for lacrosse sticks that uses an IMU to give the absolute position of the stick. The goal is to use it to guess the speed of the ball shot, and I will use that as a way to practice machine learning.
My main question is implementing the system to get the IMU data back to the computer. I am thinking of using bluetooth to transmit the data, but since the field is so big I would like to put a receiving antenna on each corner of the field, or have multiple directional antennas pointing to different sectors of the field.
Is there a way to implement bluetooth (LE or Classic) with multiple antennas? Is there a better technology to use? and should I do the calculations on the stick with a bigger uC and infer from the neural network on the uC?
