File transmission method and device based on Bluetooth technology

Abstract

The invention discloses a file transmission method based on a Bluetooth technology, which starts a Bluetooth transmission client and comprises the following steps of: acquiring a local file list; searching all moving Bluetooth equipment within an effective range to obtain a current moving Bluetooth equipment list; caching the current moving Bluetooth equipment list; selecting a file to be transmitted from local files; selecting destination equipment from the current moving Bluetooth equipment list; and when a file transmitting command is received, transmitting the file to be transmitted to the destination equipment. The invention also provides a file transmission device based on the Bluetooth technology, comprising a trigger module, a file list module, an equipment list module and a file transmission module. The file transmission method and device search the obtained current moving Bluetooth equipment list through cache, prevent from searching again after the files are transmitted each time, greatly save the waiting time, obviously enhance the operation efficiency and simplify the operation process.

Description

technical field [0001] The invention relates to computer software technology, in particular to a bluetooth technology-based file transmission method and device. Background technique [0002] Bluetooth (Bluetooth) technology is a wireless transmission technology that can perform wireless communication and data exchange within a short distance. And many other advantages, so it has been widely used in a large number of digital devices. [0003] Since the emergence of Bluetooth technology, great progress has been made in terms of transmission speed, signal quality and power consumption. There are a large number of software for data exchange using Bluetooth, but the process of data transmission using Bluetooth connection has not changed much. Such as figure 1 As shown, the process includes: [0004] Step 101: Select the file to be transmitted in the file selection interface; [0005] Step 102: Start Bluetooth search, search for all currently active Bluetooth devices within th...

AI Technical Summary

Problems solved by technology

[0009] First, when the number of active bluetooth devices within the effective range is small, the speed of searching and finding the target device in step 102 is acceptable, but when there are many active bluetooth devices within the effective range, searching and finding all the target devices will require a longer period of time;

[0010] Secondly, when multiple file transfers are performed, step 101 to step 103 must be repeated each time, so that all currently active Bluetooth devices within the effective range need to be re-searched each time, and this will undoubtedly waste a lot of time, especially When the target device for multiple file transfers is the same device, this repeated search will cause cumbersome operations and unnecessary waste of time. At the same time, the repeated search process itself will consume a lot of unnecessary system resources
