Embodiment 1

[0023] figure 1 It is a flow chart of a multi-Bluetooth device information transmission method according to a method embodiment of the present invention. like figure 1 As shown, this embodiment includes:

[0024] Step S102, the server creates a session, and multiple clients perform Bluetooth pairing with the server through the session;

[0025] Step S104, the server puts the information that needs to be output to each client into the output buffer corresponding to each client respectively;

[0026] In step S106, each client obtains information from its corresponding output buffer through the Bluetooth Object Exchange OBEX specification according to a preset time interval.

[0027] In this embodiment, information may include data and / or instructions. This embodiment uses the server to create a specific storage area bound to the Bluetooth device for storing information data transmitted to the corresponding Bluetooth device, thereby solving the problem that information cannot...

Embodiment 2

[0029] In this embodiment, the server needs to transmit files to multiple bluetooth devices as an example for illustration. figure 2 It is a flowchart of a method for transmitting information from multiple Bluetooth devices according to Embodiment 2 of the method of the present invention. like figure 2 As shown, this embodiment includes:

[0030] Step S202, the server creates a session, multiple clients are paired with the server through the session, and the server and multiple clients are connected through the Bluetooth Object Exchange OBEX specification;

[0031] Step S204, the server creates a data output buffer corresponding to each client, and binds the client and the corresponding data output buffer according to the Bluetooth address;

[0032] Step S206, the server divides the file to be output according to the number of clients, obtains the data to be output to each client, and puts the above data into the data output buffer corresponding to each client;

[0033] S...

Embodiment 3

[0038] At present, the inability of Bluetooth devices to be used interactively is also one of the problems existing in the prior art. This embodiment relates to Bluetooth transmission and image technology, and is a method for realizing split-screen display interaction by transmitting image data and control signals through Bluetooth OBEX. In order to facilitate the understanding of this embodiment, a brief description of the system implementing the present invention is given first. image 3It is a schematic diagram of a system for implementing the method for transmitting information from multiple Bluetooth devices in Embodiment 3 of the method of the present invention. In this system, the files are image files.

[0039] image 3 The system shown includes a server A and at most 7 clients B. Data and instructions are transmitted between the server and the clients through the OBEX specification, and both C and D are for sending and receiving data conforming to the OBEX specifica...

Abstract

The invention discloses information transmission method and system for a plurality of Bluetooth equipments. The method comprises the steps of: creating a session by a server, and carrying out Bluetooth pairing with the server by a plurality of clients through the session; respectively storing information to be input to the clients into output buffering zones corresponding to all the clients by the server; and respectively acquiring the information from the corresponding output buffering zones by the clients through a Bluetooth OBEX (Object Exchange) specification according to a preset time interval. In the invention, the server is used for creating a special storage zone for binding the Bluetooth equipments and storing information data to be transmitted to the corresponding Bluetooth equipments, therefore, the problem that information transmission cannot be carried out on the plurality of Bluetooth equipments is solved.

Description

technical field [0001] The present invention relates to the technical field of data transmission in the communication industry, in particular to a method and system for information transmission of multiple bluetooth devices. Background technique [0002] Bluetooth wireless technology is a short-range wireless communication technology developed by the Bluetooth Technology Alliance. The main advantages of Bluetooth wireless technology are low power consumption, low cost and rich upper layer application specifications. The Bluetooth specification has now been developed to version 3.0, with the Bluetooth Audio Transmission Model Protocol (Advanced Audio Distribution Profile, referred to as A2DP), File Transfer Protocol (File Transfer Protocol, referred to as FTP), Hands-Free Profile (Hands-Free Protocol, referred to as HFP) ), Headset Profile (HSP for short) and Object Push Profile (OPP for short) and other upper-level specifications, the maximum transmission speed can reach 24...
