This leverages Android's AdvertisingSet API (available since API 26) with extended BLE 5.0 advertising, which allows calling setAdvertisingData() on a running advertising set without any visibility gap. The update is particularly useful for simulating sensors with changing readings, QA testing of scanner apps, electronic shelf label simulation, and proximity marketing scenarios where continuous device visibility is critical. A device capability check is included since extended advertising support varies by chipset. Trade-offs include incompatibility with legacy BLE 4.x mode and the asynchronous nature of payload updates. ## Full article daily.dev links to this article rather than hosting it.
