Bluetooth technology is one of the widely used wireless communication standards. From the perspective of market and industry trends, the popularity of Bluetooth Low Energy (BLE) consumer devices such as wearable devices, mice, joysticks, BLE, etc. The cost advantage of semiconductor materials and the tendency of mobile devices to have more than BLE GATT (Generic Attribute) Profile and computer system-side BLE HID (Human Interface Device) Profile standard communication protocols make Bluetooth technology mainstream.
On the other hand, with the maturity and stability of the Internet of Things technology, low power consumption and long-term operation have become necessary conditions for wireless communication. On July 13, 2017, the Bluetooth Special Interest Group (Bluetooth SIG for short) announced the Bluetooth Mesh Profile communication protocol standard. This specification has gradually expanded its influence on industry-specific IoT applications. Combined with the decentralized system trend, there is no so-called host concept. Instead, devices and devices cooperate and communicate with each other. A controller host is needed to get rid of traditional control. Through control lines and sensors or drivers, data transmission or control is achieved. purpose. From these signs and trends, it can be seen that BLE is unstoppable from the mobile device market to the industry application of the Internet of Things, and it is simultaneously driving the realization of intelligent lighting.
In the past, the wireless communication protocol of the lighting industry is more well-known as the Zigbee communication protocol, but this communication protocol frame and the mobile phone or information system need to be connected through a gateway or router. The chip cost and system construction cost are relatively high. And Bluetooth technology makes the controller or gateway architecture no longer necessary, and breaks through the gap that the lighting system in the past could not directly interact with handheld devices. In addition, through the data packet retransmission mechanism, and the packet time-to-live parameter (TTL) can adjust the network performance according to the size of the case.
From the user’s perspective, the biggest advantage of Bluetooth is that it can read data from Bluetooth devices or control lamps directly from mobile phones. From the perspective of interior and exterior designers, Bluetooth Mesh technology can maintain the original design beauty without being complicated. The impact of wiring; from the field builder, Bluetooth Mesh applications are a convenient solution for maintenance, replacement and deployment.

In terms of characteristics, the Bluetooth Mesh Profile has a retransmission mechanism and a packet life cycle mechanism (the packet will automatically disappear after being transmitted several times), which can be adjusted according to the needs of different fields. Therefore, in the future technology development, knowledge of setting these detailed parameters will be one of the difficult projects that need to be overcome in the future for system deployment.
In wired applications, it can be connected to the Bluetooth Mesh Profile system through IP networks (such as Modbus / IP, BACNet / IP and other standards), further integrated with building automation systems, to achieve intelligent networking application environments for customers, and to improve people’s convenience, Effective, energy-saving daily needs.
