Dusun IoT’s Bluetooth Low Energy beacon devices are hardware transmitters using BLE 4.2/5.0/5.2 protocols to broadcast their identifier to nearby BLE gateways and readers.
This enables applications such as Bluetooth proximity marketing, indoor navigation, BLE asset tracking, etc.
As Bluetooth beacon devices are widely used in proximity marketing applications and indoor positioning system, as well as diverse locations, they often come with a variety of form factors, such as industrial-use and consumer-grade beacons, outdoor waterproof beacons, wearable beacons, card beacons, keyfob beacons, etc.
Although we just list some of them in the following sections, do not hesitate to propose your idea and let us discuss the feasibility, as we are not just a simple BLE beacon factory, we have ODM capability as well. And feel free to ask for bulk order prices!

To help developers jump-start their Bluetooth-beacon-based applications and projects, these Bluetooth smart beacon kits containing BLE modules, BT beacons, adapters, USB wires, etc., and corresponding documentation, sample code, and tools are offered to facilitate quick demos and testing.
Bluetooth LE beacons are growing in popularity in the field of worker attendance and tracking management. This personnel tracking solution assign BLE beacons in the from of key fobs or card beacons to personnel and install BLE gateways in fixed locations with given specific coordinates.
These beacons periodically broadcast signals to the surrounding area, and the gateway will automatically gather beacon signals and update position data to the cloud application. The tracking system software can then track, locate, monitor, and send alerts. The uploading time intervals can be configured. Please enjoy reading our case study on Bluetooth-based attendance management solution for construction sites.
In BLE asset tracking solutions, Bluetooth beacons can be attached to assets such as equipment, inventory, or vehicles to track their whereabouts and movement within a defined area. While the BLE WiFi gateways serve as a communication portal between Bluetooth beacons and the cloud-based platform.
Authorized users can view the movement of the assets at any time. This is extremely useful for logistics, manufacturing, and healthcare facilities to track the movement of their assets in real-time. Integrating extra sensors like temperature and humidity monitors may help businesses monitor the health conditions of their assets as well.
Bluetooth beacons can be used for Bluetooth proximity marketing campaigns. They can send targeted advertisements, promotions, or information to users’ smartphones when they come within range of the beacon. This is commonly used in retail stores, shopping malls, and event venues to engage with customers and enhance their shopping experience.
Internet of Things (IoT) Integration: Bluetooth beacons can serve as proximity triggers for IoT devices. They can initiate actions or trigger automation when a user’s device comes within range. This integration expands the possibilities for smart home automation, smart office setups, and other IoT applications.
BLE beacon gateway can automatically detect iBeacon, Eddystone, AltBeacon, or any other BLE Beacons nearby, collect data from them, and then pass on advertising data over 4G cellular, Wi-Fi, etc., to the server by MQTT/HTTPS protocols.
To make Beacon + Gateway work, firstly, you have to put beacon/tag on persons/items you may want to linked to. Beacon is a broadcast protocol based on the BLE protocol.It is also BLE salve device. Beacon will advertise data packet to the surrounding at regular intervals.
At the same time, you need to set up some Bluetooth beacon gateways. As an independant Bluetooth host, the Bluetooth gateway will receive the data packets broadcast by Beacon at intervals when performing the scanning action. The content of the packet can contain up to 31 bytes.
Meanwhile, when the BLE beacon gateway receives a broadcast packet, it will indicate which Beacon MAC address the broadcast packet comes from (each Beacon has a unique MAC address), and what the current received and transmitted signal strength indication value RSSI.
After receiving the data, Bluetooth beacon gateway will send it to cloud servers by MQTT/TCP/HTTP protocols, and cloud servers will send the command back. Learn more about What is a Bluetooth Gateway.
Fixed beacons (e.g. mounted on walls) are generally utilized in consumer-focused applications such as indoor navigation and proximity marketing in shopping malls, and fixed-point explanations at museums.
Movable/wearable beacons are typically used in conjunction with Bluetooth gateways to assist organizations or enterprises in achieving management goals such as hospital patient management (see Bluetooth roaming gateways), student management in schools, asset tracking, and so on.
BLE beacons broadcast UUID, Major, Minor, RSSI, battery level, Bluetooth name, Bluetooth MAC address, and other information to the surrounding environment on a regular basis, with UUID, Major, Minor, and Bluetooth name configurable through the mobile APP.
The firmware is classified as connectable or non-connectable. The connectable kind allows the Bluetooth beacon’s settings to be changed at any moment via a mobile phone connection. The non-connectable kind can only be linked and changed settings after 30 seconds of turning on the Bluetooth beacon.
1. The horizontal distance between Bluetooth beacons should be evenly kept to a maximum of 6-10m.
2. The vertical height of the Bluetooth beacons from the ground should be kept to around 3m; too high will affect the signal strength.
3. Bluetooth beacons are not often installed on the ceilings of structures with excessive vertical height. Bluetooth beacons may be placed up to 6m away along a wall or on the ground.
4. The width of the corridor should be considered while deploying Bluetooth beacons in interior corridors. For short corridors, deployment along the corridor’s centerline might be considered; for broader corridors, two columns should be spaced to ensure the density of deployment.
5. The entire space shall be covered in a triangular grid-like staggered distribution to assure the Bluetooth beacons’ signal strength.
6. The density of Bluetooth beacons can increased or reduced based on the deployment demands of the site, but normally maintain a distance of 6m to achieve better positioning accuracy.
7. Bluetooth beacons should avoid being deployed at corners and barriers.
Apple’s iBeacon, Google’s Eddystone and Radius Network’s AltBeacon are the three mainstream Bluetooth beacon protocols. Each protocol embeds their own format and data within the BLE broadcasting framework.
When a BLE beacon device advertises, the same packet is often delivered on all three advertising channels, increasing the likelihood that it will be received by a BLE receiver/scanner (explore Bluetooth beacon gateways). Bluetooth beacons deliver advertising packets on channels 37, 38, and 39 using GATT profiles (Discover Bluetooth GATT gateways). When a packet is received, the scanner determines if the contents are decodable, and take corresponding actions.
