When do I need the wireless sync dongle?

Article Text

The wireless sync dongle is the small USB device that comes with most Fitbit trackers. The dongle allows your tracker and computer to communicate with one another.

When do I need to use the dongle?

If you only sync your tracker with a mobile device, you don't need the dongle. Some computers that can communicate with the tracker over Bluetooth also don't need the dongle. However, because a computer's Bluetooth signal can occasionally be weak or problematic, it's a good idea to keep the dongle nearby even if you usually sync without it.

The Bluetooth-equipped computers that don't generally require a dongle are:

  • Macs with Fitbit Connect software installed
  • Windows 10 PCs with the Fitbit app for Windows 10 installed

Which trackers don't come with a dongle?

Fitbit Blaze is not shipped with a dongle since most of its features are optimized for a mobile device. If you have a Windows PC without Bluetooth, you can sync Blaze using its charging cable. To sync Blaze with any other computer that lacks Bluetooth, you can buy a dongle on the Fitbit Store

Fitbit Flex 2 and Fitbit Charge 2 don't ship with a dongle. Dongles are available for sale on the Fitbit Store.
