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.

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.

• 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 for implementation details.
