The Bluetooth® Market Update

The Bluetooth® Market Update provides updated forecasts and trends in key Bluetooth solution areas and highlights Bluetooth use cases that will drive future growth.


Could you please share a few case studies that illustrate these applications?

Bluetooth Mesh Control Systems for Plant Growth Lamps

Lighting, temperature, humidity, pH, CO2 levels, and other factors can significantly affect the growth of plants in indoor plant factories, and managing these factors requires massive manpower and resources. Dusun works with many lighting manufacturers on Bluetooth® Mesh applications, embedding Bluetooth Mesh communication modules into luminaries, which are widely used in the indoor plant-growth lighting industry. The Bluetooth Mesh gateway acts as the hub of the lighting system for precise control of the switching and intensity of luminaries to provide the right amount of light that helps plants grow when needed. It also uses built-in algorithms and environmental sensors deployed at the site to offer fine-grained and effective control of plant lighting based on the plant growth cycle and rhythm, reducing lighting load and energy costs.

Manufacturing Mesh

For example, Dusun embedded Bluetooth Mesh modules into the plant lamps of the indoor planting technology company 4d-bio and combined the Bluetooth gateway with the home assistant platform to control various functions of the plant lamps, including switch, brightness adjustment, and CCT (color temperature) adjustment to meet plant growth needs. We also incorporate the temperature and humidity sensors into the Bluetooth Mesh device network to help our customers build a complete intelligent planting solution. Lamps with Bluetooth Mesh modules can automatically adjust the brightness and color temperature based on feedback from the temperature and humidity sensors. The Dusun Bluetooth gateway simultaneously controls the temperature and humidity sensors and grow lighting, which are intelligently managed through the home assistant platform.

In addition, with Bluetooth® Mesh, Dusun helped the Fosun AIoT farm vertical agriculture lab create an intelligent management solution for the ical agriculture hydroponics lab. The IoT approach enables rapid growth of hydroponic plants in a green, healthy, and eco-friendly way; it is an emerging attempt to create an IoT agriculture in the indoor agricultural hydroponics industry.

As all devices are part of the Bluetooth Mesh network, the lab can easily monitor the growth of the plants and adapt conditions like lighting intensity or ambient temperature. For example, the lab can deploy Bluetooth sensors near the plants to sense data such as carbon dioxide, ozone levels, water temperature, and humidity, reading and adjusting this data in real time on a mobile app. With the Dusun Bluetooth Mesh gateway, customers can remotely adjust the frequency/brightness light color, and color temperature of different spectrums to accelerate the growth of different kinds of vegetables. By allowing water pumps to join the network of Bluetooth Mesh devices, managers can easily monitor and remotely operate them on the mobile app, activating the pump to drain the nutrient solution that offers plant roots nutrients and saves resources.

AoA Positioning, Enabled by Bluetooth Direction Finding, for Equipment Management in Coffee Chains

The operating cost of a coffee shop usually includes rent, shop decoration, production equipment, and staff management, the highest of which is production equipment. The large amount of equipment and raw materials required for coffee production must be monitored and managed at the backend of the shop, but the staff is often too busy with frontend production and customer reception to monitor the use of various equipment at the backend. Employing additional staff will increase the operating cost of the shop.

Bluetooth® technology will continue its iteration of enriching sophisticated applications.

To improve operational efficiency, a well-known coffee chain purchased and connected the Dusun Bluetooth® edge computing gateway to its coffee shop management system. The Bluetooth edge computing gateway collects and then transmits data on the usage of coffee machines, ice machines, and raw material storage equipment to the shop’s APP through network ports, Wi-Fi, or 4G cellular and cloud terminal communication. This enables online management of equipment status and energy consumption as well as monitoring raw material storage and usage in the shop’s back area. This approach can efficiently save labor costs and allow for real-time detection of equipment abnormalities and energy consumption to better improve efficiency.

How do you think Bluetooth technology will influence the growth of IoT markets in the future?

Given the huge existing market for Bluetooth® technology and the support and leadership from the Bluetooth Special Interest Group (SIG), Bluetooth technology will continue its iteration of enriching sophisticated applications, such as AoA/AoD positioning and other location service use cases enabled by Bluetooth Direction Finding. Furthermore, thanks to its easy connectivity with smart devices, such as mobile phones, I believe Bluetooth technology will bridge the communication between smart devices and other IoT protocol-based solutions.
