Problems solved by technology

Data communication cannot be performed between two USB interfaces in slave mode, so USB slave devices with USB slave interfaces cannot be applied to mobile terminals, which greatly limits the application range of USB slave devices
[0003] In addition, due to the wide application of Bluetooth technology on mobile terminals, products that convert Bluetooth technology to USB interfaces have appeared in the market; The cost is high, and at the same time, the product does not have the function of USB slave mode, which brings inconvenience to users; and the existing Bluetooth-to-USB interface products use general-purpose input and output ports to realize the connection between the main controller and the wireless communication module, reducing data transmission. Speed ​​and stability of data transmission
In addition, Apple series products such as iPhone and iPad have a high market share. To connect peripheral devices to this series of products and perform data interaction with them, they must pass MFI (MadeforiPod, MadeforiPhone, MadeforiPad) certification. None of the peripheral devices can be applied to this series of products, and the Bluetooth-to-USB interface products in the prior art do not have the above-mentioned MFI authentication function

Abstract

The invention discloses a signal transfer control method. The signal transfer control method comprises the following steps: detecting access of universal serial bus (USB) equipment and identifying that the USB equipment is either slave equipment or master equipment; if the slave equipment is accessed, starting a master mode of a USB on-the-go (OTG) interface and enumerating the USB equipment; if enumeration is successful, opening a serial port and processing master mode data of the USB equipment; if the master equipment is accessed, charging the USB equipment, starting a slave mode of the USBOTG interface and enumerating the USB equipment; and if enumeration is successful, processing slave mode data of the USB equipment. The invention also discloses a signal transfer device, so that a product capable of combining a Bluetooth technology with the USB interface has the benefits of achieving double functions of the master equipment and the slave equipment. Serial port communication is adopted, so the data transmission rate and the data transmission stability are enhanced. A made for iphone (MFI) authentication function is added; the application range of the system is enlarged; a display function is added; the system performance is improved; and the user experience is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a signal transfer control method and a signal transfer device. Background technique [0002] At present, the widely used USB (Universal Serial Bus, Universal Serial Bus) interface is divided into two modes: master mode and slave mode; for example, the USB interface of a personal computer is usually the master mode, and the USB interface of a commonly used mobile terminal such as a mobile phone is usually a slave mode. model. Data communication cannot be performed between two USB interfaces in slave mode, so a USB slave device with a USB slave interface cannot be applied to a mobile terminal, which greatly limits the application range of the USB slave device. [0003] In addition, due to the wide application of Bluetooth technology on mobile terminals, products that convert Bluetooth technology to USB interfaces have appeared in the market; The cost is high, and at the same ...
