The right IoT Bluetooth gateway will enable you to leverage the potential of IoT in your processes while still being cost-effective whether you are factory owners, manufacturers, or any industry.
What is Bluetooth Gateway
A Bluetooth gateway is a device that connects Bluetooth products to other devices, sending the endpoint information to the cloud server. These gateways serve an important purpose in connecting non-IP devices like sensors, tags, and displays. Bluetooth gateway gets more and more wide use becasue of the increasing market share of BLE (Bluetooth Low Enengy), and a large amount of BLE devices are employed by various IoT applications.

How to Choose a Bluetooth Gateway
Bluetooth Protocol Standard
It is crucial to know if the Bluetooth gateway supports compatibility with current standard protocols because the Bluetooth protocol is constantly being updated and adding new features. The Bluetooth protocol’s older version and the Bluetooth gateway’s newer version are backward compatible. Try to choose the most recent protocol when buying a Bluetooth or BLE gateway. Choose the Bluetooth 5.0 gateway, which is backward compatible with Bluetooth 4.2/4.0 and other protocols.

Connectivity Options
Many IoT platforms use Bluetooth and Ethernet for close-range connectivity, Wi-Fi and Wireless LAN for needs requiring longer-range connectivity. Manufacturers and plant owners are increasingly using their smartphones to remotely monitor activities in their factories or plants. There are IoT gateway designs that support longer-distance connectivity options like GSM/GPRS-based and LTE-M.
In this regard, not all IoT gateways are created equal, and generally speaking, the more affordable the gateway, the fewer connectivity options are offered, which is a crucial factor to take into account.
The gateway should support common protocols like Modbus, MQTT, and OPC UA in addition to standard ones like TCP/IP and HTTP. A gateway used in an industrial environment should also have multiple serial interfaces, LAN interfaces, and USB ports.

Number of Bluetooth Connections
If you pick a Bluetooth gateway, you can use it to link Bluetooth products like beds, lamps, and blood pressure monitors for data transmission applications. Depending on how many Bluetooth devices need to be connected, you can select a Bluetooth gateway.
Broadcasting, Scanning & Connection Working Modes
It may be necessary for users to connect to Bluetooth devices, control switches, etc., as well as to collect data occasionally. At this time, when choosing a Bluetooth gateway, you need to choose a Bluetooth gateway that can support broadcasting, scanning, and connection at the same time. The Bluetooth gateway from DusunIoT supports three operating modes: broadcast, scan, and connect.
Usage Scenarios of Bluetooth Gateway
Bluetooth gateways can be used in many different situations, but the following situations frequently involve them. The following various usage scenarios will influence your decision.
- Indoor scene: A Bluetooth gateway with a less expensive engineering plastic shell is an option.
- Outdoor scene: A waterproof Bluetooth gateway is an option for outdoor settings. You can select a Bluetooth gateway that supports 4G
- Mobile scene: A Bluetooth low-energy gateway with a SIM card slot is an option if installing network cables or connecting to WiFi is not convenient.

Centralized Management and Configuration
Bluetooth gateways are used for interconnection control. As an Internet control center, a project application requires hundreds or even thousands of Bluetooth gateway devices to be deployed according to the site. Since all gateways can be upgraded or changed at once, switching from one Bluetooth gateway to another, it can be less stressful and time-consuming to choose a Bluetooth gateway that can be centrally managed and configured.
Data Filtering of Bluetooth Gateway
When selecting a Bluetooth gateway, you should take into account the Bluetooth gateway filtering method, which can disable other devices while they’re working and minimize the processing of junk data. The use of the Bluetooth gateway will be hampered by other Bluetooth devices in the vicinity.
DusunIoT Bluetooth gateway already supports four ways to filter Bluetooth devices, including semaphore value RSSI, Bluetooth device name, Beacon UUID, and CompanyID.
Price of Bluetooth Gateway
DusunIoT is the world’s leading supplier of Bluetooth gateways. Among similar Bluetooth gateway products, DusunIoT’s Bluetooth gateway has a considerable advantage in price.
