Whole house intelligent lighting control is the most typical and practical design concept of home intelligence in recent years. Intelligent lighting control can meet the needs, finely set the brightness and color, and intelligently adjust the lighting when the environment changes. Therefore, compared with the traditional home light control, it has the characteristics of energy saving, convenience and comfort. Because of these advantages, more and more manufacturers have begun to invest in the development of intelligent lighting control systems. The use of Bluetooth mesh network technology can automatically and quickly perform Bluetooth pairing and establish network connections, and accelerate the deployment of smart home ecosystems.

Bluetooth Mesh Network Introduction
mesh topology, multi-hop network

Bluetooth Mesh Networking is a network topology of Bluetooth Low Energy BLE used to establish many-to-many device communication. It allows the creation of large networks supporting thousands of Bluetooth mesh devices communicating with each other.

Introduction to Module Networking

The E104-BT10 Bluetooth mesh ad hoc network module independently developed by Ebyte supports the sig mesh V1.0 standard and the sig standard HSL model. The mobile APP can proxy any node into the network, realize remote control of the mesh network, and realize the application scenario of light control with one key.


Implementation steps of smart light control


A), initialize node 1, power on node 1 serial port to send 02 c0 15, receive 03 43 15 and the initialization is successful.

B) Node 1 accesses the network, sends 02 c0 09 through the control module E104-BT10-G and waits for a few seconds, and receives 0B 40 09 CA F7 EF FB F9 EC 00 02 03, indicating that the network access is successful.

C), Node 2 accesses the network, sends 02 c0 09 through the control module E104-BT10-G and waits for a few seconds, and receives 0B 40 09 CA F7 EF FB F9 EC 00 05 03 to successfully access the network, and the same is true for other nodes to access the network. Similar to the return code, the third and second bytes from the bottom represent the network access address.

Node switch light control, E104-BT10-G or mobile phone as proxy node control. For example, E104-BT10-G sends command 09 c1 00 02 82 02 01 00 00 00, returns 08 41 00 02 00 01 82 04 01 to control node 1 to turn on the light, 09 c1 00 02 82 02 00 00 00 00, returns 08 41 00 05 00 01 82 04 00 can control node 1 to turn off the lights.
