• Install gatt and test it works with sudo gattctl --discover: https://github.com/getsenic/gatt-python
• Get the mac of your Turn Touch using gattctl and update monitor.py appropriately (remember to unpair your tt from everything else first!)
• simply run sudo python3 monitor.py. Press some buttons and if everything is set up correctly, you will see it respond!
