To connect, you need to tap the Bluetooth icon in the app. Before doing so, make sure the derailleur hasn't gone into sleep mode. If it has, just give the derailleur a tap or shake the bike to wake it up. Once the connection is successful, the Bluetooth icon will light up — and you're all set to start adjusting your derailleur.
