Fitbit Charge 6 HR Equipment

[Pablo0515]

Hello,

is there any documentation available for communicating over BLE with the HR Equipment feature of the Charge 6?

We have an fitness app for the gym that we would like to integrate the fitbit charge 6 with.

Any help (especially pairing) would be appreciated.

Hi @Pablo0515 - the only way to communicate with the Charge 6 is via the Fitbit App.

There is no SDK for this watch so your post is moved to the watch forum.

@Pablo0515 you need to use BLE HR profile: https://www.bluetooth.com/specifications/specs/heart-rate-profile-1-0/

It's pretty standard and easy to use on Android (not sure about iOS). Charge 6 should work but may require more complex handshake process (hence it's often not working with software that doesn't use encryption which is most of the software).

Thank you for the reply. I have seen the heart rate profile. But i could not manage the handshake, nor find info about the implementation.

Does fitbit share this handshake info somewhere? I’d like to be able to receive the heart rate data in our monitor app.
