Method for establishing classic bluetooth connection between dual-mode bluetooth devices, and dual-mode bluetooth device

A method for establishing a classic Bluetooth connection between dual-mode Bluetooth devices, comprising:

• sending, by a second dual-mode Bluetooth device, a Bluetooth low energy advertising packet to a first dual-mode Bluetooth device, wherein:
• based on the Bluetooth low energy advertising packet, a status of the classic Bluetooth connection of the second dual Bluetooth device is determined;
• and
• based on the status of the classic Bluetooth connection of the second dual Bluetooth device, a user is promoted to operate the first dual-mode Bluetooth device or the second dual-mode Bluetooth device so as to establish a classic Bluetooth connection between the first dual-mode Bluetooth device and the second dual-mode Bluetooth device.

A dual-mode Bluetooth device, comprising:

• a transceiver, configured to receive a Bluetooth low energy advertising packet sent by a second dual-mode Bluetooth device;
• at least one processor and one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
• determine a status of the classic Bluetooth of the second dual-mode Bluetooth device according to the Bluetooth low energy advertising packet;
• and
• prompt, according to the status of the classic Bluetooth of the second dual-mode Bluetooth device, a user to operate the first dual-mode Bluetooth device or the second dual-mode Bluetooth device to establish a classic Bluetooth connection between the first dual-mode Bluetooth device and the second dual-mode Bluetooth device.
