Also important to note that when you select the 4 bytes [00 00 00 40] and enter the value into the "Single (float32)" field, if your sensitivity has decimal places like mine did, you need to change the full stop to a comma when copying and pasting it from this website, otherwise you will get the ["______" is not a valid "Single (float32)"-value] error.
Example: 0.133941966 will be 0,133941966. Hope this helps!
