Description

Connection method and related device The present application is a divisional application, the application number of the original application is 202510848585.0, the original application date is 2025, 6 and 23, and the whole content of the original application is incorporated by reference. Technical Field The present application relates to the field of communications technologies, and in particular, to a connection method and a related device. Background With the development of wireless communication technology, people have become familiar with connecting different intelligent terminal devices in a wireless manner. For example, the electronic device may establish a communication connection with the external device, thereby allowing the electronic device to perform some functions in conjunction with the external device. However, in some communication technologies, for example, star flash (Near Link) and bluetooth low energy (bluetooth lowenergy, BLE), the electronic device generally uses the external device as a broadcasting end to send a broadcast packet to the electronic device if the electronic device is to establish a communication connection with the external device. The electronic device may serve as a scanning terminal for scanning broadcast packets transmitted by the external device. If the broadcast packet sent by the external device is scanned, the electronic device may determine whether the white list has an address identifier of the external device, and if the white list has an address identifier of the external device, the electronic device may send a connection request to the external device, where the white list has address identifiers of one or more devices paired with the electronic device but not establishing the target communication connection. The external device may establish a communication connection with the electronic device upon receiving the connection request. However, this connection mode is inflexible and cannot meet the requirement of free connection switching of multiple devices. Disclosure of Invention The application provides a connection method and a related device, which can prevent a first electronic device from frequently contending with other devices to establish communication connection with a second electronic device after receiving a first broadcast packet sent by the second electronic device. In a first aspect, an embodiment of the present application provides a connection method, which is applied to a first electronic device, and the method includes receiving a first broadcast packet sent by a second electronic device, where the first broadcast packet carries an address identifier of the second electronic device, where the first broadcast packet is a connectable broadcast packet, if the first broadcast packet carries the first identifier, automatically connecting back to the second electronic device without being based on a white list of the first electronic device, and if the first broadcast packet does not carry the first identifier, automatically connecting back to the second electronic device based on the white list of the first electronic device. According to the connection method provided by the embodiment of the application, after the first electronic device receives the first broadcast packet, if the first broadcast packet carries the first identifier, the second electronic device is automatically connected back without being based on the white list of the first electronic device. And if the first broadcast packet does not carry the first identifier, automatically connecting back to the second electronic device based on the white list of the first electronic device. In this way, the second electronic device can inform the first electronic device whether to automatically connect back to the second electronic device based on the white list by whether the first identifier is carried in the first broadcast packet. The first electronic device can be prevented from frequently competing with other devices to establish communication connection with the second electronic device after receiving the first broadcast packet sent by the second electronic device. In one possible implementation manner, if the first broadcast packet does not carry the first identifier, the second electronic device is automatically connected back based on the white list of the first electronic device, which includes that if the white list of the first electronic device has the address identifier of the second electronic device and a first instruction of initiating connection with the second electronic device by an application is not acquired before the first broadcast packet is received and the first broadcast packet does not carry the first identifier, a first communication connection is established with the second electronic device. In this way, the first communication connection is established with the first electronic device based on the white list automatic reconnection mechanism under th
