Bluetooth Heart rate sensor

Some devices (Mi Band 2, Mi Band 3, Mi Band 4, Amazfit Bip) support acting as a BLE HR sensors. You can enable this feature in the Device specific settings: 3rd party realtime HR access.

Do note, that this can contribute to higher energy consumption of the band/watch. Also, other apps/device might connect to your band without your knowledge (TODO: confirm connection from unpaired device).

Once enabled, Gadgetbridge doesn’t need to be running and the data is still available via Bluetooth LE. You need to run an Activity on the band/watch or, be in the Status screen (Bip), for the Heart rate data to be sent.

Some example known apps to work with these data:

Here is how you can see your HR in BLE Explorer

Once the sharing is enabled and activity is started on the device (or status screen on Bip is used) live data is visible in BLE Explorer, in the Heartrate section, first line (the 00002a37... characteristics). You must enable the notify toggle. GB does not need to run nor be connected anymore, the sensor remains available but you must keep the activity running, for fresh data to be sent.
