If the device ID of the first target device is the same as the device ID of the first device, the first device will use the network ID of the first device and the network ID of the second device in the wireless Initiating a connection to the second device in the network.

Here, when the device identifier of the first target device is the same as the device identifier of the first device, it can be understood that the device that the second device expects to communicate with is the first device. When the device identifier of the first target device is different from the device identifier of the first device, it can be understood that the device with which the second device expects to establish a communication connection is not the first device.

When the device identifier of the first target device is different from the device identifier of the first device, the process may end. Or, in order to achieve a one-to-one connection, step 803 may further include:

If the device identifier of the first target device is different from the device identifier of the first device, the first device determines whether the first device has established a communication connection with the second device;

If the first device has established a communication connection with the second device, the first device disconnects the communication connection with the second device.

Optionally, the access information of a first device includes the device identification of the first device, and when the second device obtains the access information, the second device may obtain the second device expectation according to the access information. The device identifier of the first target device that establishes the communication connection is the access information of the first device. For example, as shown in FIGS. 3A to 3C, the access information of the first device a1 may include the device identification of the first device a1, and the second device b1 may include the first device in obtaining the access information of the first device a1. The device identifier of a1. At this time, the first device a1 can be understood as the device that the second device b1 expects to establish a communication connection. It can be seen that the access information of a first device includes the device identification of the first device, so that the second device can obtain the device that the second device expects to establish a communication connection through the access information of the first device.
