The Industrial Internet of Things requires a large amount of data to support, where the data comes from, how to transmit the data, and how to transmit the data to ensure the quality of the transmission. These are the issues that physical network engineers need to consider. Bluetooth is leading the convergence of industry and information, paving the way for the Industrial Internet of Things revolution and helping manufacturers improve efficiency, productivity and safety. In this article, the Internet of Things expert SKYLAB will briefly introduce how to use the Bluetooth module to quickly realize data transparent transmission in the field of industrial Internet of Things.
Bluetooth data transparent transmission
Let me briefly explain what is data transparent transmission? Transparent transmission refers to a data transmission method that has nothing to do with the medium of the transmission network, the mode of modulation and demodulation, the mode of transmission, and the transmission protocol. Data transparent transmission means transparent transmission, which means that in the process of data transmission, the set of data does not change in any form through wireless means, as if the transmission process is transparent, while ensuring the quality of transmission, and it reaches the final receiver intact.
In actual industrial production, smartphones and tablets are gradually replacing traditional human-machine interfaces (HMIs) for condition monitoring and remote control of equipment. In the field of industrial Internet of Things, Bluetooth-based asset positioning solutions and data transmission solutions are gradually becoming popular, and have achieved the market mission of helping manufacturers and distributors optimize inventory management and improve operational efficiency.
Transparent transmission of the Bluetooth module: 0 built-in complete wireless protocol stack, supports serial port transparent transmission mode, users can use it quickly without cumbersome RF hardware design or wireless protocol development, greatly reducing R&D investment and shortening the product R&D cycle. It provides an optimal solution for designers to meet the ever-increasing demand for faster data rates and the flexibility to adapt to current and future communication applications.

SKB369
SKB369 based on Nordic nRF52832 solution is a highly integrated BLE4.2 Bluetooth module, designed for wireless 2.4GHz ISM high-speed transmission, supports UART serial data transparent transmission, with 32-bit ARM Cortex-M4F CPU, flash memory and analog and digital computer peripherals.
SKB501
The SKB501 based on the Nordic nRF52840 solution is a highly integrated BLE5.0 Bluetooth module, which has the advantages of good performance, low power consumption, high receiving sensitivity, long transmission distance, and small package. Supporting SPI/UART/TWI communication protocols, the product can be better embedded into customer products, and at the same time meet customers' needs for rapid programming of Bluetooth products again.
SKB378 is a highly integrated Bluetooth 5.2 module, which can be used for high-speed, short-range wireless communication in the 2.4GHz ISM frequency band. Industrial-grade standard, supports master-slave mode (1 master to 8 slaves), supports serial port transparent transmission, AT command control, and supports AoA Bluetooth high-precision indoor positioning. The module integrates a 32-bit ARM Cotex-M33 processor with a main frequency of 76.8MHz. It also has built-in 32kB RAM and 512kB Flash, and supports analog or digital peripherals. The receiving sensitivity is as high as -106.7dBm, and it can realize data transparent transmission at a distance of 50+ meters. It is the preferred Bluetooth solution for IoT data collection, data transparent transmission, intelligent control, AoA Bluetooth beacon, and AoA Bluetooth gateway.
SKB378 has rich peripherals, such as UART, SPI, SmartCard-ISO7816, IrDA, I2S, I2C, PDM, etc.
SKB378 is more cost-effective, supports low power consumption mode, and the sleep current is less than 1.8μA. The size, module appearance and package are consistent with the existing BLE4.2 Bluetooth module SKB369 and BLE5.0 Bluetooth module SKB501. In terms of performance, SKB378 has lower power consumption and can transmit longer distances.
In the field of device network solutions, Bluetooth technology has been rich in applications and practices. BLE-based smart lighting, smart door locks, smart access control and other solutions can be applied to offices, warehouses, retail locations and other large commercial spaces, not only providing advanced control functions for building managers, but also helping to save energy and improve efficiency. Practical use cases have shown that users can reduce building energy costs by 70% - 75% through smart lighting and advanced lighting control, and this immediate effect has also stimulated the vigorous growth of the related market. Annual shipments of Bluetooth commercial lighting, switches and controllers will reach nearly 8 million by 2026, many of which will accelerate the adoption of other commercial building use cases.
