Embodiment 1

[0068] Please refer to figure 2 , this embodiment provides a method for autonomously networking among multiple devices to realize wireless screen transmission, which is suitable for allowing devices that set data in Bluetooth broadcasts to conduct autonomous networking through Bluetooth and realize screen transmission.

[0069] When there is no network (of course, the user can also choose to use the method of this implementation to realize the network without the network), through the following method, realize the independent network between the devices without the network, so as to ensure the normal screen transfer between the devices .

[0070] The methods include:

[0071] S1: The screen transmission terminal broadcasts the data including IP address, port number and Wi-Fi name via Bluetooth.

[0072] This step realizes that the screen transmission end broadcasts the networking data through the GAP.

[0073] Specifically, this step can be achieved through the following s...

Embodiment 2

[0088] Please refer to image 3 , this embodiment is further expanded on the basis of the first embodiment to support autonomous networking through Bluetooth between devices that are not allowed to set data in the Bluetooth broadcast, and to realize screen transmission.

[0089] Usually, in order to ensure data consistency, MAC O Officials of S and iOS do not allow setting data in the broadcast. For such devices that do not support custom Bluetooth broadcast data, this embodiment provides a method for realizing autonomous networking between devices through Bluetooth GATT. The same as Embodiment 1 will not be repeated, and the difference is:

[0090] In the S3 step, if the receiving end cannot read the data broadcast by the screen transmission end, that is, the broadcast object Discovery and the screen transmission end device object cannot be resolved, then the following steps are performed:

[0091] S5: The receiving end and the screen transmitting end establish a connectio...

Embodiment 3

[0103] This embodiment corresponds to Embodiment 1 and Embodiment 2, provides a specific application scenario, and will take the autonomous networking between a screen transmission device A and a screen transmission receiving device B as an example for illustration. Among them, device A can be any device that supports Bluetooth 4.0 or above technology and has screen transmission components, such as mobile phones, tablets, computers, etc.; device B can also be any device that supports Bluetooth 4.0 or above technology and has screen transmission components, such as mobile phones , tablet, computer, projector, electronic whiteboard, etc.; the screen transmission component of the device uses Wi-Fi or other methods to transmit the screen. In this embodiment, the essence is to use the Bluetooth module as a device discovery component to realize discovery and networking between devices.

[0104] First, both device A and device B start the discovery component;

[0105] Then, device A...

Abstract

The invention provides a method for achieving wireless screen transmission by autonomous networking among multiple devices, a screen transmission end and a receiving end. The method comprises the steps that the screen transmission end carries out Bluetooth broadcasting on data including an IP address, a port number and a WiFi name; a receiving end finds the Bluetooth broadcast and reads the data;and the receiving end sets the data into a screen transmission assembly. The invention can be simultaneously suitable for autonomous networking and screen transmission among any equipment with a Bluetooth function under the condition of no network, and has the characteristics of simplicity and convenience in operation, high practicability and the like.

Description

technical field [0001] The invention relates to the field of wireless screen transmission, in particular to a method for realizing wireless screen transmission through autonomous networking among multiple devices, a screen transmission terminal and a receiving terminal. Background technique [0002] Today is the first year of the outbreak of wireless screen transmission technology. According to official data, 4G mobile Internet users have accounted for more than half of the country's total population, coupled with the upcoming 5G era, this provides a quality guarantee for wireless screen transmission technology. The native airplay, microcast and dlna technologies are based on Wi-Fi wireless transmission and local area network capabilities, which not only solve the compatibility problem between devices, but also make it easier for users to access devices to obtain wireless projection effects, more stable, and better viewing effects. better. [0003] The so-called wireless s...
