KT6368A BLE Bluetooth Chip Application Case Study in Smart Home Scenarios: Smart Lighting Control System

1. Introduction to KT6368A Chip

The KT6368A is a high-performance Bluetooth 5.1 dual-mode module supporting both BLE and SPP protocols. It features low power consumption, high sensitivity, and long-range transmission. Key specifications from the user manual include:

• Frequency range: 2.402GHz–2.480GHz

• Transmit power: Up to 8dBm

• Receiver sensitivity: -94dBm

• UART interface communication

• Core architecture: 32-bit RISC-V @48MHz

• On-chip memory: 64KB SRAM

• Configurable via AT commands

These characteristics make it ideal for various smart home applications.

2. Smart Lighting Control System

Use Case: Control home lighting via smartphone app or voice assistant

Implementation:

• Integrate KT6368A into smart bulbs or switches

• Direct Bluetooth connection from a smartphone or via a gateway

• Receive control commands to adjust brightness, color temperature, etc.

Advantages:

• Low power consumption for always-on devices

• Fast response (<100ms latency)

• Supports group control for multiple lights

Reference: Similar to Philips Hue but with a lower-cost solution using KT6368A

3. Smart Lighting System Setup

1. Hardware Connection:

2. Software Development:

 // Example: Lighting control logic  
   void handle_ble_command(uint8_t cmd, uint8_t value) {  
       switch(cmd) {  
           case CMD_BRIGHTNESS:  
               set_pwm_duty(value);  // Adjust brightness  
               break;  
           case CMD_COLOR_TEMP:  
               adjust_color_temp(value);  // Modify color temperature  
               break;  
           // Other commands...  
       }  
   }

1. AT Command Configuration:

 AT+NAME SmartBulb_01      // Set device name  
   AT+ROLE=SLAVE             // Slave mode  
   AT+ADVINT=500             // 500ms advertising interval

1. Mobile App Development:Use Android/iOS Bluetooth APIs to connect to KT6368AImplement control UI and scene modes
