Sensor telemetry does not have to travel over UWB. The same Sensor TLV payload can ride BLE extended advertising, broadcasting connectionless to any listener in range.
No ranging session, no pairing — a phone, a gateway or an observing anchor can receive telemetry without joining a UWB schedule.
Extended advertising with a full sensor payload needs a BLE controller and stack that support extended advertising. Devices with that capability can transmit or receive the BLE ext-adv sensor carrier; the receive (decode-and-forward) path lets an anchor aggregate telemetry broadcast by nearby tags.
The advertising PHY and TX power are themselves runtime parameters (0x81, 0x82), so range and robustness are tunable per deployment without a firmware change:
| Parameter | ID | Values |
|---|---|---|
| Sensor carrier | 0x7C | 0 = UWB frames, 1 = BLE ext advertising |
| BLE advertising PHY | 0x81 | 0 = 1M, 1 = Coded (long range) |
| BLE TX power | 0x82 | int8, dBm |
BLE ext advertising reaches listeners that are not part of a UWB TDMA schedule. Because it reuses the Sensor TLV format unchanged, adding it cost no new record definitions and no second decoder — the format follows the transport, but the payload does not change.
The Coded PHY trades data rate for range; the 1M PHY provides the higher rate.
