Referring to fig. 1, an embodiment of the present invention provides a wireless audio device pairing method, including:
s10, establishing temporary connection between a first wireless audio device and a second wireless audio device, wherein the first wireless audio device and the second wireless audio device are the wireless audio devices with the strongest RSSI signal intensity searched by the first wireless audio device and the second wireless audio device;
s20, sending first pairing information to the second wireless audio equipment, and receiving second pairing information sent by the second wireless audio equipment;
and S30, if the first pairing information and the second pairing information are determined to meet the preset pairing condition, pairing with the second wireless audio equipment.
In this embodiment, the wireless audio device may be a wireless bluetooth headset, a wireless bluetooth speaker, or other wireless audio devices. The first wireless audio device and the second wireless audio device are generally two wireless audio devices, such as a left ear earphone and a right ear earphone, which are paired, or two bluetooth stereo speakers which are matched with each other. RSSI, an abbreviation of the english term Received Signal Strength Indication, is a chinese meaning of the Received Signal Strength Indication, belongs to an optional part of the wireless transmission layer, and is used to determine the link quality and whether to increase the broadcast transmission Strength.
In step S10, only when the first wireless audio device and the second wireless audio device are matched with each other with the strongest RSSI, the first wireless audio device and the second wireless audio device can establish a temporary connection. In other words, the first wireless audio device and the second wireless audio device are placed close enough to each other so that they are both the matching devices with the strongest RSSI of each other, and thus the two devices establish a temporary connection. Therefore, the matching equipment with the RSSI not being the strongest can be eliminated, and the matching time is shortened.
After the first wireless audio device and the second wireless audio device establish the temporary connection, the two wireless audio devices exchange pairing information with each other to determine whether the two devices are the same type of device in step S20. The first wireless audio device receives second pairing information sent by the second wireless audio device. The second wireless audio device receives the first pairing information sent by the first wireless audio device.
In step S30, the second wireless audio device determines whether the received first pairing information satisfies a first predetermined condition, and the first wireless audio device determines whether the received second pairing information satisfies a second predetermined condition. If the two conditions are met simultaneously, the first wireless audio device and the second wireless audio device are adapted, and at this time, the two devices are successfully paired. After the two wireless audio devices are successfully paired, the two wireless audio devices can be connected with a smart phone or a notebook with a Bluetooth function as a whole, and then a playing function is realized on the wireless audio devices.
Optionally, step S10 includes:
the first wireless audio equipment receives the trigger instruction, starts an RSSI scanning mode and searches for the second wireless audio equipment with the strongest RSSI signal intensity;
sending a first temporary connection request to the second wireless audio device, and judging whether a second temporary connection request of the second wireless audio device is received;
and if the second temporary connection request is received, establishing temporary connection with the second wireless audio equipment.
In this embodiment, the first wireless audio device and the second wireless audio device establish a temporary connection in the following manner: the first wireless audio equipment receives the trigger instruction, starts the RSSI scanning mode and searches for the wireless audio equipment with the strongest RSSI signal intensity. And if the wireless audio equipment with the strongest RSSI signal strength searched by the first wireless audio equipment is the second wireless audio equipment, sending a first temporary connection request to the second wireless audio equipment. Meanwhile, the second wireless audio equipment receives the trigger instruction, starts the RSSI scanning mode and searches for the wireless audio equipment with the strongest RSSI signal strength. And if the wireless audio equipment with the strongest RSSI signal strength searched by the second wireless audio equipment is the second wireless audio equipment, sending a second temporary connection request to the first wireless audio equipment. When the first wireless audio device receives the second temporary connection request, then a temporary connection is established with the second wireless audio device.
Optionally, step S10 includes:
the first wireless audio equipment receives the trigger instruction, starts an RSSI scanning mode and searches for the second wireless audio equipment with the strongest RSSI signal intensity;
sending a first temporary connection request to the second wireless audio device;
and if receiving the acceptance information of the second wireless audio equipment responding to the first temporary connection request, establishing temporary connection with the second wireless audio equipment.
In this embodiment, the establishing of the temporary connection between the first wireless audio device and the second wireless audio device may be further performed in the following manner: the first wireless audio equipment receives the trigger instruction, starts the RSSI scanning mode and searches for the wireless audio equipment with the strongest RSSI signal intensity. And if the wireless audio equipment with the strongest RSSI signal strength searched by the first wireless audio equipment is the second wireless audio equipment, sending a first temporary connection request to the second wireless audio equipment. And if receiving the acceptance information of the second wireless audio equipment responding to the first temporary connection request, establishing temporary connection with the second wireless audio equipment.

and determining the found wireless audio equipment with the strongest RSSI signal strength as the second wireless audio equipment.
In this embodiment, both the first wireless audio device and the second wireless audio device receive the trigger instruction. The triggering instruction may refer to the wireless audio device being converted from a standby state to an operating state, or may refer to the wireless audio device being converted from a power-off state to an operating state. Taking the first wireless audio device as an example, when the first wireless audio device enters the working state, the RSSI scanning mode is enabled, and the signal transmitted by the second wireless audio device that needs to be matched is detected. The first wireless audio device enabling the RSSI scan mode sets the RSSI signal strength threshold. Only wireless audio devices that are greater than a predetermined RSSI signal strength threshold will be paired with the first wireless audio device. This ensures that the paired wireless audio devices are close enough together, while avoiding the need to search for a wireless audio device that is further away. The RSSI signal strength threshold of the first wireless audio device and the second wireless audio device can be set to-50 dbm. Through tests, when the first wireless audio equipment and the second wireless audio equipment are placed in the same charging box, the received RSSI signal strength is greater than-50 dbm for the first wireless audio equipment and the second wireless audio equipment. In step S22, if the strongest RSSI signal strengths obtained by the first wireless audio device and the second wireless audio device are less than-50 dbm, the scanning is continued.

In this embodiment, after the first wireless audio device and the second wireless audio device are paired, second pairing information sent by the second wireless audio device is stored on the first wireless audio device, and first pairing information sent by the first wireless audio device is stored on the second wireless audio device. When the pairing information of the other party is stored in the two wireless audio devices, the process of matching the pairing information is reduced, and the pairing time between the devices is greatly shortened.

and if the searched RSSI signal strength is lower than a preset threshold value, sending a reminding signal.
In this embodiment, the RSSI signal strength found is lower than the preset threshold, which indicates that no wireless audio device meeting the condition can be matched, and at this time, the first wireless audio device may send a reminding signal to remind the user that the pairing is not completed.
Optionally, the step of sending the alert signal includes:
the reminder signal is emitted in a flashing red flash.
In this embodiment, a small LED lamp may be provided on the first wireless audio device, and the color of the LED lamp may be red. And when the pairing is not successful, a flashing red flash is used for sending out a reminding signal to remind the user that the pairing is not completed.
Optionally, after the step of sending the first pairing information to the second wireless audio device and receiving the second pairing information sent by the second wireless audio device, the method further includes:
and if the first pairing information and the second pairing information do not meet preset pairing conditions, sending a reminding signal.
In this embodiment, if the models of the second wireless audio device and the first wireless audio device are not matched, the two devices cannot be paired, and at this time, a reminding signal is sent to remind the user that the matching is not successful.
Optionally, before the first wireless audio device receives the trigger instruction, the method further includes:

The two charging contacts are connected by a data line. The charging box is provided with a Hall switch and is arranged on the data line. When the charging box is closed, the Hall switch is in a closed state, and the data line is not communicated. And when the charging box is opened, the Hall switch is in an opening state, and the data lines are communicated. When the data lines are connected, the two wireless audio devices can generate a triggering instruction.
