BOB

Bob is a powerful tool that helps you track the displacement of a punchball or a punchbag. The app is connected via bluetooth to a device with a BLE micro-controller in order to send and receive data, form sound feedback and keep track of the correct hits.

Bob sends and receives data from an embedded system, through a BLE low energy gatt protocol. In order to use Bob, you need to have an Arduino or some micro-controller that is equipped with bluetooth.
