The main chip module 120 is connected to the first wireless module 110, and is configured to control, according to the hotspot name and its corresponding password, the first wireless module 110 to access the wireless hotspot corresponding to the hotspot name, and in the smart The hotspot name and its corresponding password are shared internally by the terminal.

The computer module 130 is connected to the main chip module 120 and the second wireless module 140, and is configured to acquire the hotspot name shared by the main chip module 120 and its corresponding password, and control according to the hotspot name and its corresponding password. The second wireless module 140 detects and accesses a wireless hotspot corresponding to the hotspot name.

The first wireless module 110 and the second wireless module 140 may be, for example, a WIFI module. The first wireless module 110 is connected to the main chip module 120, and the first wireless module 110 can detect the wireless hotspot of the surrounding environment and display it on the operation interface of the smart terminal.

The main chip module 120 and the first wireless module 110 are connected by wire, and receive and share the wireless hotspot name connected to the first wireless module 110 inside the smart terminal. The wired connection may include: USB, integrated circuit bus (Inter- Integrated Circuit (IIC), Universal Asynchronous Receiver/Transmitter (UART), and Serial Peripheral Interface (SPI). The main chip module 120 has a built-in memory or a memory externally stored therein, and the memory stores a password corresponding to the hotspot name in the surrounding environment, or when the user inputs the password of the wireless hotspot for the first time, the password corresponding to the hotspot name is stored in the memory. The main chip module 120 calls the password corresponding to the selected hotspot name according to the hotspot name selected by the user on the operation interface of the smart terminal, and controls the first wireless module 110 to connect to the selected wireless hotspot; the main chip module 120 can also be based on the detected wireless The signal strength of the hotspot is high, and the first wireless module 110 is preferentially connected to the wireless hotspot with the highest signal strength according to the detected hotspot name and its corresponding password.
