Problems solved by technology

After the traditional Bluetooth headset is paired and connected with the mobile phone, it is mainly used for making calls and listening to music. In recent years, although there are Siri voice assistants on Apple phones, and major mobile phone manufacturers on Android phones have also launched similar voice assistants, but overall The functions of these voice assistants are not practical enough, and the understanding of the context in the communication process is also lacking
Therefore, some voice interaction apps with better experience are emerging, but these apps cannot use Bluetooth headsets for interaction, because the microphone used for voice input by Bluetooth headsets is turned off by default, so it cannot pick up sound at all.

Embodiment Construction

[0031] Attached as follows figure 1 Further description of the application scheme:

[0032] Although the broadcast packet sent by a general BLE device will also include information such as the device name and Bluetooth address, there is nothing special about it. The user needs to select a device he needs on the mobile phone screen to connect. Just like when a person arrives at the airport in a strange city for the first time, the person who picks up the plane only tells you that he is waiting for you at the exit, so once you arrive at the exit, you will become at a loss when you face a long line of people who pick up the airport. But if the two parties agree on a coded number, and then ask the pick-up person to hold a sign with the coded number, you can find him accurately with a glance.

[0033] Therefore, we apply it to the manufacturer data packet of the broadcast packet, which is composed as follows (see Table 1 below):

Abstract

The invention provides a Bluetooth headset voice interaction communication method based on the BLE, the voice interaction function between the Bluetooth headset and the terminal APP is achieved, and the confusion that a user selects BLE equipment is avoided. The method specifically comprises the following steps that a manufacturer data packet in a BLE broadcast message of the Bluetooth headset isdefined; wherein the manufacturer data packet comprises a Bluetooth headset Mac address field, a Magic character string field and a verification field; wherein a Magic character string is recorded inthe Magic character string field; wherein the Magic character string is preset in software codes of a Bluetooth headset and a terminal APP; the Bluetooth headset broadcasts a BLE broadcast message; the terminal APP receives the BLE broadcast message, extracts the Mac address of the Bluetooth headset from the BLE broadcast message, constructs the manufacturer data packet by itself according to a preset Magic character string and the obtained Mac address, and calculates to obtain a corresponding verification md5 value; the md5 value is taken to be compared with the received BLE broadcast message, if the md5 value is consistent with the check field content in the BLE broadcast message, it is judged to be the target equipment, and the terminal APP establishes a BLE link for the target equipment.

Description

technical field [0001] The invention belongs to the technical field of bluetooth earphones, and in particular relates to a BLE-based voice interactive communication method for bluetooth earphones. Background technique [0002] In recent years, the Bluetooth headset market has developed rapidly, the sound quality is getting better and better, and the price is gradually falling. On the other hand, voice assistants and translation assistant apps on mobile phones are becoming more and more mature. After the traditional Bluetooth headset is paired and connected with the mobile phone, it is mainly used for making calls and listening to music. In recent years, although there are Siri voice assistants on Apple phones, and major mobile phone manufacturers on Android phones have also launched similar voice assistants, but overall The functions of these voice assistants are not practical enough, and the understanding of the context of the communication process is also lacking.
