1. Product Overview
The Holyiot NRF52810 Beacon is part of a product series that includes Bluetooth Low Energy (BLE) modules and BLE beacons. Both products utilize low-power Bluetooth communication technology, characterized by low power consumption, stable transmission, and wide coverage. The Bluetooth Low Energy module is designed for integrating Bluetooth communication functions into various smart devices, enabling core functions like data collection and instruction transmission. Bluetooth low power beacons are ideal for scenarios such as indoor positioning, asset tracking, and information push, providing efficient wireless communication support for Internet of Things (IoT) applications.
Manufacturer: Shenzhen Holyiot Technology Co.,LTD.
2. Setup and Installation
2.1 Instructions for Use of Low-Power Modules
- Preparatory Work: Confirm that the module model matches your application equipment. Prepare the necessary power supply, connection cables, and supporting development tools (if applicable).
- Hardware Connection: With the device powered off, connect the power pins (VCC, GND) of the module to the corresponding power interface, ensuring correct polarity. For communication, connect TX and RX pins as required. Refer to the product pin diagram for specific pin definitions.
- Parameter Configuration: Configure the module's Bluetooth name, communication baud rate, broadcast interval, connection password, and other parameters using the accompanying development tools or AT commands.
2.2 Instructions for Using Low-Power Bluetooth Beacons
- Power Installation: If configured, open the beacon housing and insert the battery according to specifications, ensuring correct positive and negative pole placement.
- Parameter Configuration: Connect the beacon via the accompanying configuration APP. Set parameters such as broadcast interval, transmission power, UUID, and Major/Minor values. Refer to the APP's operation guide for detailed procedures. For operation instructions, contact sales-aliexpress@holyiot.com.
- Installation and Fixation: Choose an appropriate installation location based on the application scenario (e.g., walls, ceilings, asset surfaces). Secure the beacon using double-sided tape or other fixation methods to ensure a firm installation without signal obstruction.
3. Operation
3.1 Function Test (Low-Power Modules)
After power-on, the module will enter its normal working state. Search for the module's Bluetooth name using a serial port command or the accompanying APP. Establish a connection and perform data transmission tests to confirm normal functionality.
3.2 Work Test (Low-Power Bluetooth Beacons)
Once installed, the beacon automatically enters broadcasting mode. Use a Bluetooth device to search for the beacon signal and verify that the signal strength and broadcasting stability meet requirements.
Note: This beacon is a semi-finished product. The factory-provided program is for testing hardware functionality only and does not include actual application functions. Users must write and burn their own firmware for specific application scenarios.
3.3 Using the Holyiot-beacon APP
The Holyiot-beacon APP allows for configuration and monitoring of the device.
- Download the "Holyiot-beacon" APP from the App Store or scan the provided QR code.
- Search for the device according to its type (beacon/iBeacon/Eddystone). Android phones may not support switching between beacon/iBeacon/Eddystone; use an iPhone for this operation if needed.
- Connect to the device for more information. The app displays details such as device name, RSSI, MAC address, temperature, humidity, pressure, vibration detection, button state, and battery level.
- Click "Connect", enter the default password (e.g., "aa14061112").
- View more details and configure parameters within the app.
- Change the beacon/iBeacon/Eddystone mode of the device as required.
4. Maintenance
When the product reaches the end of its life, please sort and recycle it in accordance with local electronic waste disposal regulations. Do not discard it improperly to avoid environmental pollution.
5. Troubleshooting
5.1 Usage Restrictions and Potential Issues
- Communication Distance Limitation: The actual communication distance can vary due to environmental factors such as obstructions, electromagnetic interference, environmental humidity, and supporting equipment performance. For optimal communication, ensure an open and unobstructed environment. Refer to the product specification sheet for specific distance details.
- Working Environment Restrictions: The product requires a clean, dry environment free from strong interference. Operating outside the specified temperature and humidity range (as detailed in the product specification sheet) can lead to performance degradation, malfunction, or damage.
- Software Compatibility Restrictions: The Bluetooth Low Energy module requires compatibility with devices or systems supporting BLE 4.0 or above. Verify the Bluetooth version compatibility of your accompanying device before use.
