The Bluetooth gateway is an relay device that receives BLE data from terminal devices and uploads it to the server through the network. It serves as a Bluetooth bridge enabling non-IP BLE-devices to connect to the Internet, so that users are allowed to check status of BLE endpoint information from anywhere in the world, and control BLE devices by exchanging data bi-directionally.
For instance, one can use a Bluetooth gateway to interconnect BLE-enabled temperature and humidity sensors, air conditioners, and humidifiers at home, so as to achieve centralized and automated management, keeping you home within a consistent range to provide a comfortable living environment.
Constitution and Working Principle of Bluetooth Gateways
A smart Bluetooth gateway is an IoT gateway hardware that integrates a Bluetooth module and other network communication modules (Ethernet, WiFi, Cellular LTE 4G, Zigbee, Z-Wave, etc.). The role of Bluetooth module in the Bluetooth gateway is to scan and connect nearby BLE devices, and and obtain data from scanned BLE devices.
High bandwidth network communication modules (Ethernet &WiFi, Cellular LTE 4G.) are used to send the gathered data, in the form of TCP/UDP, to the backend cloud server. If there is a control command, the server will forward the command over the Bluetooth gateway to the associated BLE terminal device. In this way, the Bluetooth gateways performs its bi-directional communication and device control functions.
The Bluetooth gateway may also add other communication modules, such as Zigbee, LoRaWAN, etc., in order to support more IoT application requirements. Bluetooth gateway may also be used in conjunction with other IoT gadgets like cloud servers, smart terminals, sensor nodes, etc., to form a more complete IoT system. Explore fundamental elements of IoT here.
Typical Bluetooth gateways also include a central processing unit for dealing with complicated tasks, and power management modules in charge of powering the entire device.
Reasons to Require Bluetooth Gateways
Due to the low power consumption, simple connection, and strong interoperability of Bluetooth technology, the demand for BLE-enabled devices such as door locks, oximeters, and lighting is growing rapidly. Bluetooth gateway has emerged in response to the demands of a large number of Bluetooth devices need to transmit data to the background application server, and the truth that traditional one-to-one and short-distance transmission can no longer meet the needs of the Bluetooth IoT.
The Bluetooth gateway can support multiple sub-devices to access the network, manage the data collection, and interconnection of sub devices, and synchronize the information to the cloud through WiFi/Ethernet/Cellular LTE 4G. Users can remotely monitor and operate Bluetooth items through the mobile app, greatly extending the functionality and value of original Bluetooth devices.
BLE VS Bluetooth gateway, What’s the difference?
BLE Gateways for Smart Door Locks
For smart locks that are on standby for 24 hours and have high power consumption requirements, Bluetooth low energy consumption is more suitable, BLE is better suited as communication protocol than WiFi. Wi-Fi demands a lot of power, and if it’s powered by dry batteries, the battery life will be drastically reduced. Furthermore, the transmission data required by the smart lock is far less than that supported by the Wi-Fi transmission protocol, which may result in a waste of resources. Therefore, to equipp a BLE gateway for smart locks is not just for connectivity with other smart home gadgets, but also for safety and battery life concerns.
Additionally, by utilizing BLE gateway as a relay to allow smart door locks to access the Internet and transmit the lock’s dynamic information, users can operate the door lock (remotely check door lock state, issue temporary passwords, receive reminders of family members approaching home, and prompt alarming of aberrant status) at any time via the mobile APP. The BLE gateway can connect many BLE devices, and they may be linked with each other to perform automated scenarios such as turning on the lights when the door is opened.
How to use Bluetooth Gateways?
Step 1: find a place to install Bluetooth gateway
Before using Bluetooth gateways, find an appropriate place to position it at first. Take Bluetooth WiFi gateway as an example, the wireless signal strength and coverage varies depending on the actual environment, and may be affected by factors including concrete constructions, wall thickness, etc. For optimum Bluetooth and Wi-Fi performance and extend device lifespan, please:
1) Avoid placing the gateway in a location where it will be exposed to moisture or excessive heat.
2) Keep away from strong electromagnetic radiation sources and electromagnetic-sensitive devices.
3) Place the gateway in a spot where it can be wired up to a power supply and linked to the various sub devices.
You may place the Bluetooth gateway on a shelf or desktop, or paste the gateway on the ceiling and walls. We have PoE ceiling/wall mountable Bluetooth gateway for selection.
Step 2: Make primary configuration
Connect the gateway with a router and get the IP address of the gateway. Log in the gateway by inputing Gateway IP address on a web broswer. Enter username and password, then you can check the status of gateway information (host name, firmware version, local time, memory. Network, etc.)
Step 3: Finish Internet setting and LAN setting according to user manual.
Step 4: Make Sub-devices Connection
The Bluetooth gateway works by scanning and connecting BLE devices. Users can use filtering options such as RSSI, BLE device name, MAC address to filter the specific devices you want and then connect. After the connection is established, Bluetooth gateway will caches the data structures of characteristics and services of the device. User can notify the value or write configuration to the BLE devices. Here we have a detailed demo about developing an application over Bluez APIs to manipulate BLE devices.
Step 5: Make Cloud configuration
After Bluetooth gateway recognizes the features and data structures of surrounded BLE devices, it can send the data to the cloud server through the MQTT(TCP/SSL) protocols. You need to fill in the parameters obtained from the Azure/AWS/Tuya platforms to enable gateway connected with the cloud. Then filled in the right value offered by MQTT broker. SSL certificate can be used to enhance the communication security, here we have an MQTT SSL example.
Backhaul Connectivity of Bluetooth Gateways
After collecting a large quantity of data from sub devices, Bluetooth gateways use high bandwidth network such as WiFi, Ethernet, or Cellular network to transfer data to the Internet. What’s difference between these three types?
WiFi and Cellular network transmits data via wireless signals, while Ethernet transmits data over cable. If you prefer mobility and flexibility, you can choose WiFi and Cellular. Cellular covers large areas such as cities and towns, it can be a failover option of Bluetooth gateway, especially in outdoor environment. While Wi-Fi only transfer data within limited areas such a home building, or airports. As for Ethernet, it can have a better experience on quicker speed, lower latency, and a more reliable connection.
Whether you are going to choose WiFi, Ethernet, or Cellular as broadband connectivity choice, Dusun IoT has a wide range of Bluetooth gateways for selection. Do not hesitate to contact us and place an order!
How Do Bluetooth Gateway Communicate with the Cloud?
HTTP and MQTT are two popular application layer protocols to make data exchange and communication between Bluetooth gateway device and the cloud. But we usually recommend to use MQTT for its advantages such as small code footprint, simple and compact architecture, publish-and-subscribe model, ideal for resource-constrained IoT scenarios.

Types of Bluetooth Gateways
Bluetooth SIG has divided Bluetooth technology into four fit-for-purpose solutions: audio streaming, data transfer, location service, and device network. Bluetooth gateway involve three of them.
Bluetooth Data Transfer Gateway
Bluetooth GATT is a general specification for sending and receiving very short data segments over a Bluetooth connection. Bluetooth data transfer gateway adopts Bluetooth GATT to enables two-way communication.
Bluetooth gateway often plays the role of Central, and sub devices as peripherals. A peripheral can only be connected to one central device at a time, but the central device can be connected to
multiple peripherals. For Dusun IoT Bluetooth gateways, it can connect up to Dusun 32 devices at the same time.

Bluetooth Location Positioning Gateway
In indoor positioning, the Bluetooth gateway plays an important role. It gathers and transfers the BLE data broadcast by the iBeacon device to the server for calculation. The background positioning algorithm will output the location information of the iBeacon after computation. There are two types of Bluetooth position service gateways, based on RSSI and AoA technologies:
Bluetooth Beacon Gateway based on RSSI
Received Signal Strength Indicator (RSSI) can be used to estimate the distance between transmitter and receiver. Once the power of the transmitter is known, the position of the items can be estimated by measuring the signal attenuation.
In Blutooth RSSI location tracking solution, a BLE beacon gateway reads the RSSI value from BLE beacons and upload it to a cloud server. The background server can calculate the distance between the iBeacon device and the Bluetooth gateway using this RSSI value, and the BLE Beacon device’s location may be shown in real time on the background map.
The Bluetooth gateway’s scanning range can also be designated as a safe region at the same time. The iBeacon gadget may sound a security alarm in the background once it exits the safe range. This is the working principle of BLE-based personnel and asset management solution.
Since RSSI can only roughly estimate the distance, if you consider that low cost is more important than increased accuracy, RSSI based location systems can be your choice. Furthermore, you can improve the accuracy level of RSSI-based indoor location systems by increasing the number of beacon/tag devices.
Bluetooth Beacon Gateway based on BLE AoA
Compared with Bluetooth RSSI, Bluetooth Angle of Arrival is obviously a much more accurate method for indoor positioning. The Bluetooth RSSI accuracy is generally within 3 to 5 meters, while BLE AoA positioning can reach to 0.1-0.5 meter average accuracy.
Bluetooth Angle of Arrival (BLE AoA) works by having a Bluetooth Tag transmitting a special direction-finding signal. While the receiving device, a AoA locator that has multiple antennas arranged in an array, receives the signal from the tag. When the signal passes through, it will generate a phase difference due to the different distances received in the array, and then the relative signal direction can be calculated, which greatly improves the accuracy of Bluetooth positioning, so as to provide much more accurate location services.
BLE AoA wins popularity not only because of its higher accuracy , but also thanks to its flexibility, high concurrency, low cost, low power consumption, and high compatibility, which means the IoT projects and solutions can effectively save costs brought about by large-scale positioning tag/beacon applications on various people, vehicles, and objects.
When you choose an indoor location technology, do remember that, there is no absolute advantages or disadvantages. The key point is to look at your application scenarios, you need to choose location solution and technology depending on what uses you want to serve, or the complexity, budget, robustness and so on.

Bluetooth Mesh Network Remote Control Gateway
Bluetooth Mesh allows people to establish a many-to-many (m:m) relationship between wireless devices. Devices can also transmit data to other devices that are not directly covered by the original device’s radio signal. Mesh networks are able to connect a lot of devices and cover a lot of space physically. One of the biggest advantages of BLE mesh is that users can use mobile phone to access Bluetooth mesh network and manage all nodes, without relying on Bluetooth gateways. But once someone leaves the range of BLE mesh network, he cannot perform remote access, status check, and device control.

How many Bluetooth devices can the Bluetooth gateway connect and control at the same time?
Considering the stable and reliable connection and data transfer, we recommend 7-10 slave Bluetooth devices at the same time. But the exact number may be decided by bandwidth you want, BLE mode, and Bluetooth SoCs you choose. If you want to get detailed info, do not hesitate to contact our engineers.
Can a Bluetooth gateway act as a Bluetooth Hub?
Bluetooth gateway can work as a Bluetooth hub to gather instructions from all parties (voice assistant, remote servers, sensor, etc.), centrally mobilize all connected smart devices within one place (e.g. home), realize the mutual interaction of all home devices, complete the automation of home scenes, and improve the comfort and convenience of life.
Does Bluetooth gateway support secondary development?
The Bluetooth gateways offered by Dusun IoT can provide SDK and API interface docking for users to quickly carry out secondary development on the basis of the original program.
What is Bluetooth protocol?
The Bluetooth protocol divides Bluetooth as a whole into a two-layer architecture. The bottom layer is the core protocol, which describes the foundation and specifications of the Bluetooth core technology, including Host and Controller. The application layer uses the mechanism provided by the core protocol to implement different functions based on specific requirements. These two parts are slightly different in different Bluetooth protocol versions. The function of the Bluetooth protocol stack is a bridge between software and hardware, which packs application data and then generates air data packets that can be sent through radio frequency and its reverse process. View more different Bluetooth version comparison here.
How Do I Connected My Bluetooth Gateway?
As we mentioned before, the configuration of Bluetooth gateway is very simple. What you need to do is to pair your Bluetooth end devices like beacons and sensors to Bluetooth gateway hub to get started data transmission. After the first time connection, the smart Bluetooth gateway device will automatically register the Bluetooth end devices and automatically send the Bluetooth device endpoint information to the your cloud server.
What is the range of a Bluetooth gateway?
The range of Bluetooth gateway is mainly determined by the Bluetooth chip embeded in the Bluetooth module. The output power and receiving sensitivity of Bluetooth chip will influence how far your signal can travel. Also, if you add extra antennas, the signal range may be larger. On the other hand, if there is obstacles like concrete walls, it will attenuate the radio signal.
Take DSM-054 Bluetooth module as an example, it is with up to 20 dBm maximum power output and an excellent receive sensitivity of -97 (1 Mbit/s GFSK) dBm, which means excellent receiving sensitivity and output power. what’s more. it uses an onboard PCB antenna whose frequency band is 2.400 to 2.483 GHz to optimaize RF performance.
If you want to extend Bluetooth range over hundreds or thousands of meters, you may consider Bluetooth Long Range Technology or BLE Mesh technology.
Can Bluetooth Gateway work as Bluetooth Access Point?
The Bluetooth gateway in the Bluetooth network connects the Bluetooth device to the Internet, same as the wireless AP in the WIFI network connects the WIFI device to the Internet. Therefore, the role of the Bluetooth gateway in the Bluetooth IoT is like the role of the wireless AP in the WIFI network. Know more about Bluetooth access point.
How does Bluetooth communicate with WiFi within a Bluetooth gateway?
Data is received by the Bluetooth module of the gateway, which then transmits it after connecting to the WiFi module through the serial port.
