Help! Scent Tech App says "No Device Found" via Bluetooth connection
Don't panic! Your hardware is completely fine—this is almost always a mobile OS permission issue. 🔒
When you first download the Scent Tech App, modern smartphones (especially iOS 15+ and Android 13+) prompt you for permissions. If you decline even one, the app becomes blind.
Follow this quick 3-step checklist:
The Location Permission Trap: On Android and iOS, the app requires "Location Services / Precise Location" permissions to be enabled alongside Bluetooth. Why? The OS groups Bluetooth LE (Low Energy) scanning under location privacy. Go to your phone's Settings -> Scent Tech -> Enable Bluetooth & Location (Always or While Using).
Distance Check: Bluetooth LE has an effective pairing range of under 15 feet (5 meters). Move closer to the machine during the initial sync.
Hard Reset: If the pairing signal freezes, unplug the power adapter from the back of the diffuser for 10 seconds, plug it back in, and tap refresh in the app
