Abstract
This application relates to the field of terminal technologies, and provides a Bluetooth communication method, a wearable device, and a system, to avoid always maintaining an HFP connection, so as to avoid an unnecessary delay or a call error caused when an electronic device processes a voice message. The Bluetooth communications system includes an electronic device and a wearable device, and an HFP connection is established between the electronic device and the wearable device. When the electronic device meets a preset condition, the HFP connection is automatically disconnected. The electronic device sends a first notification to the wearable device after receiving an incoming call, to reestablish the HFP connection. In this case, the electronic device may answer the incoming call by using the wearable device.
