Holyiot 21011 nRF52810 BLE 5.0 Beacon w/ Sensors

Download the official Holyiot-beacon app from your smartphone's app store. Power on the beacon, ensure Bluetooth is enabled on your phone, and open the app. It should automatically detect the nearby beacon. Within the app's configuration menu, you can select the beacon type (iBeacon, Eddystone, or Universal), set the desired advertising interval (affecting battery life and update rate), and adjust the transmit power level from -40 dBm to +4 dBm. Changes are saved directly to the device's non-volatile memory.

With the included 220mAh CR2032 battery, expect up to 180 days of operation under typical default settings. To maximize battery life, use the configuration app to increase the advertising interval (e.g., from 100ms to 1 second or more), which reduces the number of radio transmissions. Also, set the transmit power to the minimum level required for your application, as higher power levels consume more current. Ensure the device is operating within its specified temperature range, as extreme cold can reduce battery capacity.

The beacon houses sensors for temperature, humidity, and barometric pressure. This data is typically encoded within the beacon's advertising packet payload, specifically in user-defined manufacturer data fields when configured in a custom or Eddystone TLM (Telemetry) mode. You need a compatible BLE scanner app or a gateway device programmed to parse these specific advertisement packets. The data is not accessible via a direct connection like GATT; it is broadcasted. The motion detection likely triggers a change in the advertisement pattern or content to indicate a vibration event.
