Method for automatically installing bluetooth serial port equipment

Abstract

The invention relates to a method for automatically installing bluetooth serial port equipment. The method is used for automatically installing the bluetooth serial port equipment on embedded equipment or a mobile terminal based on a Windows Mobile or Windows CE operating system. The method comprises the following steps of: (1) starting a local bluetooth function on the embedded equipment or the mobile terminal, and searching available bluetooth equipment: comparing the searched available bluetooth equipment with preset names one by one until a matched preset name is found, acquiring the address of the available bluetooth equipment, and pairing and acquiring a radio frequency communication (RFCOMM) channel number of the available bluetooth equipment; and (2) searching a serial port number available for use in a system, creating a virtual serial port for the serial port number on the basis of the address of the available bluetooth equipment and the RFCOMM channel number, returning the corresponding serial port number to upper application, and directly providing a virtual serial port which effectively operates target bluetooth serial port equipment for the upper application if indicating that the bluetooth serial port equipment is successfully installed.

Description

Technical field [0001] The present invention relates to Bluetooth technology and virtual serial port technology in embedded devices or mobile terminals, in particular to a method for automatically installing Bluetooth serial devices. The method is used in embedded devices or mobile terminals based on Windows Mobile or Windows CE operating systems. Bluetooth serial device is automatically installed on the computer. Background technique [0002] At present, various embedded devices and mobile terminals using Windows Mobile or Windows CE operating systems are widely used in various industries, and many supporting Bluetooth devices are used at the same time, such as Bluetooth printers, Bluetooth keyboards, and Bluetooth remote controls. Because the communication between Bluetooth devices is realized based on the virtual serial port, the programming is simple, and the transmission of small data is convenient and fast, so Bluetooth serial devices are often given priority in industrial ...

Problems solved by technology

[0010] However, although the Windows Mobile or Windows CE operating system provides complete support for Bluetooth technology, although the programming based on the virtual serial port is as simple as based on the traditional serial port, but in terms of the current implementation of the operating system, for a Bluetooth serial device from the search It is quite complicated to get an effective and operable virtual serial port after installation: these installation / uninstallation options are scattered in different setting items, and have order dependence, and in some cases even need to directly perform registry entries through ActiveSync Add or delete operations, which will bring some system security issues, but also greatly increase the technical requirements for end users
