# Why does realtime streaming return success but no events?

Real-time streaming only works with devices that **actively broadcast heart rate over BLE**. A successful `startRealtime`/connection only means the session was registered, not that data is flowing.

Many consumer, budget or older bands (for example some Xiaomi Mi Band models) do not reliably expose HR over BLE broadcast and are not supported for streaming.

A few checks:

* For Whoop, enable `Settings > Device Settings > Broadcast HR`.
* If a connection succeeds but no data arrives, toggle the phone's Bluetooth off and on, then retry.

No additional dashboard configuration is needed for real-time streaming; the [SDK integration](https://docs.tryterra.co/streaming-api/connect-wearable-to-sdk) alone is sufficient. Note that the `ALL_DEVICES` scan type is Android-only.
