Is it possible to pair a Bluetooth chest strap to an Amazfit Stratos 3?

By  Joe Horner 2019-09-23 12576 1

Recently, many friends have emailed to ask Gearbest Blog, whether the Xiaomi Huami Amazfit series smartwatches or the latest Amazfit Stratos 3 supports connecting to Bluetooth HRM chest strap. Of course, the answer is inconsistent, because not all Amazfit smartwatches are supported. Next, I'll tell you which Amazfit smartwatches support external device connections and how to connect external devices.

Amazfit Stratos 3​ 

Which Amazfit smartwatches support external device connections?

Of the many Huami Amazfit smartwatches, only the latest Amazfit Stratos 3 and Amazfit Verge 2 (available only in China), support the connection of external devices.

For example, the Amazfit GTR, Amazfit GTS, Amazfit Bip series and the Amazfit PACE series do not support the use of additional connections, such as Bluetooth HRM chest strap.

Peripheral connection method

Amazfit Stratos 3 and Amazfit Verge 2 supports connected with Bluetooth 4.0 and above heart rate chest strap and A2DP Bluetooth headsets..

The above devices can be paired or connected in the peripheral connection settings in "Sports Setting" for use during such activities.


The watch will connect just one of the same Bluetooth devices at the same time. When you start an activity, the watch will actively try to connect to the most recently used device.

If you need to replace the connecting device, you can select the device that requires the active connection of the watch in the peripheral connection settings.


To connect the heart-rate chest strap:

First, wear the heart-rate chest strap on your body. (For users with dry skin, dip both sides of the strap in water.)

Find the heart-rate chest strap in the “Watch - Sports Setting - External Device” and pair and connect the strap.


Swimming mode has no external device option, Bluetooth headset can not search for connection in the external device option, you need to connect Bluetooth headset to listen to music before entering motion mode.
