Bluetooth needs to be turned on at the device level before your Blast sensor can connect, but keep in mind the sensor itself only pairs inside the Blast app — not through your phone’s Bluetooth settings menu.
iOS: How to Turn On Bluetooth
- On your iPhone or iPad, open Settings.
- Tap Bluetooth.
- Flip the On/Off toggle so it shows green.
- Close out of Settings.
- Check the top of your home screen for the Bluetooth icon, confirming it’s active.
Android: How to Turn On Bluetooth
Steps vary slightly depending on your Android device model:
- Tap the menu button and select System Settings.
- Locate the Bluetooth symbol on the settings screen.
- Change the setting to “On” by tapping to the right of “Off.”
- Close out of Bluetooth settings.
- Check the top of your home screen for the Bluetooth icon, confirming it’s active.
Important: Connect the Sensor in the App, Not in Bluetooth Settings
On both iOS and Android, turning on Bluetooth only makes the connection possible — the sensor will not appear or connect within your phone’s Bluetooth settings. You must pair it from inside the Blast app itself (Menu > My Sensor).
FAQ
Why doesn’t my sensor show up in my phone’s Bluetooth settings?
The Blast sensor is designed to connect only within the Blast app, not through your device’s native Bluetooth settings menu.
Do the steps to turn on Bluetooth differ between iOS and Android?
Yes slightly — iOS uses Settings > Bluetooth, while Android goes through System Settings, and the exact menu can vary by device model.
