First, power on the vehicle and turn on the central control system. Find the Bluetooth function in the system interface and enable it. Then connect your phone to use the car Bluetooth function. Through Bluetooth, you can answer calls, play songs, and enjoy convenient usage, improving driving safety. The following is an introduction to HFP: 1. HFP is a software that allows Bluetooth devices to control phones, commonly used in cars. It enables Bluetooth devices to control phone functions such as answering, hanging up, rejecting calls, and voice dialing. Rejecting calls and voice dialing depend on whether the Bluetooth headset and phone support these features. It is a configurable mode that allows Bluetooth headsets to enter high-fidelity calls. 2. HFP defines two roles: Audio Gateway (AG) and Hands-Free Component (HF). The Audio Gateway (AG) is a device that serves as the input/output gateway for audio (especially phones). The Hands-Free Component (HF) acts as the remote audio input/output mechanism for the audio gateway and can provide several remote control functions.
