Method and device for quickly pairing dual-mode Bluetooth equipment

Abstract

The invention provides a method and device for quickly pairing dual-mode Bluetooth devices, the method is applied to a host. The method comprises the following steps: receiving a BLE broadcast sent by a surrounding slave, the BLE broadcast comprising plaintext information and encrypted information; judging whether the plaintext information is matched with the host information or not, and if yes, decrypting the encrypted information through a public key to obtain decrypted information; and judging whether the decryption information is matched with the plaintext information, and if so, pairing with the slave according to a classic Bluetooth MAC address. According to the method for quickly pairing the dual-mode Bluetooth equipment, the pairing operation is simplified and the pairing speed is increased under the condition that the cost is not increased, meanwhile, the pairing condition is not limited by the version of an equipment system, the cost performance is high, and the applicability is high.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for quickly pairing dual-mode Bluetooth devices. Background technique [0002] The step of pairing the classic bluetooth device with mobile phones and other devices is the first step in using all classic bluetooth devices, which will directly affect whether users can use classic bluetooth devices conveniently. At present, the common open Bluetooth pairing methods on the market mainly include: traditional Bluetooth pairing method, NFC pairing method and Google Fast Pair; the traditional Bluetooth pairing method needs to enter the "Bluetooth" device interface under the It is relatively cumbersome to find the device to be paired in the device list and click pair, and it is often difficult for users to quickly find the device to be paired when there are many Bluetooth devices around or Bluetooth devices with duplicate names. Although the method of ...

At present, the common open Bluetooth pairing methods on the market mainly include: traditional Bluetooth pairing method, NFC pairing method and Google Fast Pair; the traditional Bluetooth pairing method needs to enter the "Bluetooth" device interface under the Find the device to be paired in the device list and click pairing, the operation is relatively troublesome, and when there are many Bluetooth devices around or Bluetooth devices with duplicate names, it is often difficult for users to quickly find the device to be paired

Although the method of NFC pairing is simple, it requires the chip to support the NFC function. It is necessary to add an NFC coil to the product and write the NFC information for Bluetooth pairing during production. These operations will increase the cost of the product.

Compared with the first two methods, Google Fast Pair has lower cost and relatively simple operation, but it has great limitations in use, including the need for the Bluetooth chip to support automatic BLE and BR / EDR transmission at different transmission powers. Based on Google account, the operating system only supports Android 6.0 and above
