# Can Garmin watches stream heart rate over BLE in real time?

**Real-time streaming via TerraRT works only for the metrics a device actually broadcasts over BLE.**

* Garmin watches that support heart rate broadcasting can stream **heart rate** in real time. A list of tested compatible watches (for example Fenix 6 and up) is in the [streaming documentation](https://docs.tryterra.co/streaming-api/getting-started).
* Other metrics stream only if the watch broadcasts them.
* Gyroscope and other raw sensor data are available through the real-time streaming SDK from devices that expose them (iOS/Android phones, Apple Watch, WearOS), but are not part of standard API-provider payloads, and most third-party wearables do not support them.

See the [real-time streaming documentation](https://docs.tryterra.co/streaming-api/getting-started) for implementation details.
