In recent years, the whole house intelligence has been more and more accepted by young people, and the intelligent central control system (commonly known as 86 boxes) has a broad space for development in the future. The so-called intelligent central control system is to connect intelligent lights, air conditioners, switches, sockets, door locks and smart home appliances and other equipment together for control. The 86 box central control scheme we introduced this time is a good combination of local voice control and WiFi remote control, which can be widely used in homes, offices, and hotels. When you get home, enter the office or hotel, directly turn on the corresponding mode, turn on the lights, turn on the air conditioner, etc., which is a convenient experience. The MediaTek Genio 130A (MT7933) integrates a microcontroller (MCU), an AI engine, WiFi 6, Bluetooth and a power management unit (PMU). The Genio 130A's highly integrated design provides energy-efficient, reliable, and efficient network connectivity for small form factor devices, making it the best choice for a wide range of IoT devices. Support SPI, I2C, I2S, SDIO, USB, UART and other interfaces, and can plug a variety of peripherals.

The following is a brief introduction to the program:

1. Lighting control

1) When you click the button on the UI side, send set cmd to MT7933 with on/off parameters

2) After the MT7933 end is parsed, call BLE to control the BT lamp

2. Networking

1) The UI endpoint scan, send get cmd to MT7933

2) MT7933 returns the AP list, the data format is "ap1+ap2+ap3+.. +”

3) After an AP is selected, the SSID box is filled in by default.

4) The Key interface requires the user to enter the AP password

5) UI endpoint connect, send "ssid+password" to MT7933, MT7933 to connect to the network

3. Voice

1) Once the MT7933 side recognizes the voice, it will feedback the txt content to the UI side

2) Once the MT7933 terminal recognizes the voice, it will turn on and off the light
