Optionally, in this embodiment of the application, when the first terminal device establishes the bluetooth connection with multiple terminal devices including the second terminal device at the same time, the first terminal device is configured to display, in real time, an allowed communication method and/or a prohibited communication method for each of the multiple terminal devices on a communication interface based on the bluetooth connection.

Optionally, the first terminal device determines a broadcast mode for each terminal device in the plurality of terminal devices according to an allowed communication mode and/or a prohibited communication mode for each terminal device.

Optionally, in this embodiment of the present application, the first terminal device is configured to display an allowed broadcast mode and/or a prohibited broadcast mode in real time on a communication interface based on the bluetooth connection.

The bluetooth communication interface of the terminal device 1 held by the xiao zhao displays the permitted communication mode and the prohibited communication mode for the xiao, the dui and the queen in real time. Specifically, the communication method when the xiaozhao determines that the bluetooth connection-based communication is performed with the xiaozao according to the state information may be a video and a voice, the communication method when the bluetooth connection-based communication is performed with the xiaozao may be a voice, and the communication method when the bluetooth connection-based communication is performed with the xiaowane may be a communication method (for example, a character) other than a video and a voice.

Optionally, in this embodiment, the bluetooth communication interface of the terminal device 2 held by the leaflet may also display the permitted communication mode and/or the prohibited communication mode for the zhao in real time, and may also display the permitted broadcast mode and/or the prohibited broadcast mode for the zhao in real time.
