Hello all, I hope you are doing fine!
If you are having inconveniences with your Blaze GPS connecting to your phone, I recommend checking if your phone is a compatible mobile device, if it is, take the following into consideration:
ERROR MESSAGES
You may see the following errors on your tracker:
- Phone not found: This means Bluetooth is turned off (preventing your Blaze from connecting to your phone) or your phone can't find a GPS signal. A weak GPS signal on your mobile device is often caused by environmental factors such as tall buildings, dense forest, steep hills, or even thick cloud cover. All of these can interrupt the connection between your tracker and GPS satellites.
- Check Fitbit app: This means you may need to grant location permissions on your phone or change a setting on your tracker. See the requirements below for more information.
REQUIREMENTS
- Bluetooth is enabled on your phone and your tracker is connected (paired) to the phone. To confirm, go into your phone's Bluetooth settings and make sure you see Blaze on the list of devices.
- You selected an exercise type from the Exercise menu that has a gear icon in the bottom left corner. The gear icon represents connected GPS.
- GPS is turned on for the exercise type. Tap the gear icon and make sure the Use Phone GPS setting is on.
- Your phone is within about 20 feet of your tracker.
TROUBLESHOOTING
If you're still having difficulty, try these troubleshooting steps:
- Open the Fitbit app to reestablish a connection with your tracker.
- Reboot your mobile device.
