For custom service UUID discovery:
```python
devices = await scan_devices(
timeout=5.0,
service_uuid="00000000-0000-0000-0000-000000000001",
)
```
`scan_devices()` performs an unfiltered BLE scan. If your script needs to
restrict results to a specific profile, filter or connect-verify devices in
your application code.

Use the [BLE UART Service example](../../../../examples/bluetooth/ble_uart_service) when you want a ready-made ESP-IDF Echo Server for testing BLE UART Bridge Console. After building, flashing, and pairing with the example, open Console and type any text; the example should echo the same data back as `[RX]` output.
