DSGW-210 RK3328 Multi-protocol Smart Gateway, With Li-battery Power Backup

This may depends on the modules you choose for DSGW-210 smart gateway, as different models of DSGW-210 has different connectivity options. I can not give you a certain number. Typically, BLE can support for 7-8 devices simultaneously, and if in polling status it may accommodate maximum 32 BLE devices. For Zigbee function, the smart gateway can support 30 Zigbee end device and 64 zigbee devices in total. Other wireless modules, please feel free to ask our FAE engineers at online forum.

The IoT gateway is the middleware with protocol conversion capabilities in the IoT system, connecting low-power, low-bandwidth devices to cloud servers, and offers API interfaces for cloud services. It plays the following role:

• Support a wide range of IoT protocols, including Zigbee, BLE, WiFi, etc., to enable device interoperability and mutual communication.
• Support data preliminary treatment and compression, decrease the amount and duration of data transfer, and boost system performance.
• Switch between local edge computing and cloud computing, and can control and operate devices in a disconnected environment.
• Avoids the hassle of connecting diverse devices to multiple cloud systems by offering a common API to facilitate the connection to IoT cloud services.

In summary, smart gateway is crucial to making IoT system more efficient, stable, and secure, as it aggregate device communication, data transmission, and connection between cloud services together.

Software running on the gateway plays an important role in system logging, especially in striking a balance between the number of logs entries stored on the device and those sent to the data center. It should be designed to be efficient in handling system logs, minimize storage requirements, and optimize network bandwidth usage.

The smart gateway is mainly composed of hardware and software. In terms of hardware, smart gateway devices often come with powerful CPUs, memory, and storage as well as a variety of communication interfaces including Wi-Fi, Ethernet, and Bluetooth. In terms of software, the gateway must handle multiple communication protocols, such as MQTT, HTTP, etc., as well as security concerns. It must also execute programs based on Linux and other IoT operating systems.

The smart gateway device’s data processing procedure frequently falls down into three steps: equipment data collection, data formatting, and network transfer. The gateway first gathers data from IoT devices using a variety of interfaces and sensors, formats and analyzes the data, and then sends the data across the network to another device or the cloud service platforms.

Hardware and software development are the two essential elements of smart IoT gateway development. It is required to choose hardware elements such appropriate processors, memory, and communication interfaces and to carry out tasks like circuit design and assembly. In terms of software, application programs need to be written, including drivers, data processing modules, and communication modules.

Smart IoT gateway design often entails actions like gaining access to devices, data processing, and connection to the cloud platform. IoT devices must first be linked to the gateway via a variety of interfaces, after which the data they collect must be formatted and processed. In order to complete data interchange with the cloud, the data is finally posted to the cloud service platform via a variety of broadband connectivity protocols.

To guarantee the IoT system’s dependable functioning, the smart IoT gatewat must have excellent security. Bridging hardware should generally have the following security measures in place:

Authentication and authorization: user identity authentication to prevent unauthorized users from accessing and operating the system;

Encrypted communication: use encryption algorithm to encrypt data to ensure the security of data transmission;

Security protocol: use security protocols, such TLS/SSL, to protect the confidentiality and integrity of data transfer;

Firewall: installing a firewall will increase system security;

Security Audit: Keep track of system activity logs to quickly identify and address security problems.

A typical intelligent gateway include both northbound interfaces and southbound interfaces. In order to provide services like data analysis, processing, storage, and management, the northbound interface establishes a connection to the cloud and is used to upload data there. To communicate with terminal end devices, the southbound interface is connected to the device side.

A smart IoT gateway needs to run drivers and software to serve its different operations. In terms of hardware, processors with great computational capability and low power consumption, like ARM, are frequently employed. You can choose CPU and chip platforms here according to your needs.

The DSGW-210-X-9 gateway hardware is capable of supporting OpenThread, a low-power wireless mesh networking protocol. However, the software implementation for OpenThread and its API needs to be developed on the customer side. If you require OpenThread support, it can be added to the development schedule accordingly.
