Why Won’t My Blast Sensor Activate, and How Do I Fix It?

Share:

If your Blast sensor fails to connect during activation, first try activating it again to wake it up — the sensor won’t flash until activation is fully completed. If it still won’t activate, reinstalling the app usually resolves the issue.

Step 1: Try Activating Again

Activate the sensor a second time to wake it up. Remember: the sensor will not flash until activation has actually completed, so a lack of flashing during the attempt doesn’t necessarily mean it failed.

Step 2: Reinstall the App and Reactivate

If the activation continues to fail, uninstall and reinstall the app, then walk through activation again:

  1. Uninstall the app.
  2. Reinstall the app from the App Store (or Google Play).
  3. Open the app and log in.
  4. Tap on the menu.
  5. Go to My Sensor.
  6. Tap Add a Sensor.
  7. Scan or type in the serial number. If you run into problems, tap “Having Trouble?”
  8. Shake the sensor until it connects — this should take about 5-10 seconds.

If you’re still having issues after these steps, contact Blast Motion customer support.
