Embodiment Construction

[0086] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0087] The following is an explanation of some words that appear in the text:

[0088] 1. The term "and / or" in the embodiment of the present invention describes the association relationship of the associated objects, indicating that there can be three kinds of relationships, for example, A and / or B, which can mean that A exists alone, A and B exist simultaneously, and a separate relationship exists. There are three cases ...

Abstract

The invention discloses a method and device for exchanging device information between terminals, which are used to solve the problem of poor stability in the way that members in an existing Wi-Fi group obtain device information of terminals in the group through TCP. In this embodiment of the present invention, after establishing a Wi-Fi connection group, the first terminal scans for preset BLE broadcast packets, and the second terminal broadcasts preset BLE broadcast packets while searching for the group. The preset BLE broadcast message of the two terminals establishes a GATT connection with the second terminal. After the GATT connection is established, the first terminal sends the device information of all terminals in the group to the second terminal through the GATT connection instead of the original TCP connection. Since the GATT connection of low-power Bluetooth is relatively stable compared to the TCP connection, exchanging data through the GATT connection of low-power Bluetooth can improve system stability and reduce system power consumption due to the use of low-power Bluetooth.

Description

technical field [0001] The present invention relates to the field of terminals, and in particular, to a method and device for exchanging device information between terminals. Background technique [0002] At present, data group transmission can be realized by forming a local area network between terminals. At present, there are many applications for realizing data group transmission between mobile terminals. [0003] These applications generally have the function of establishing a Wi-Fi connection group through Wi-Fi (Wireless Fidelity) hotspots and Wi-Fi direct connection. Terminals can be formed by joining the same Wi-Fi connection group, such as figure 1 local area network shown. After the group is established, the terminal that establishes the group can obtain the device information of the remaining terminals in the group, and then the terminal that establishes the group establishes a TCP (Transfer Control Protocol, Transmission Control Protocol) with other terminals i...
