Dual-Mode Bluetooth Terminal Automatic Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Bluetooth communication methods for household appliances face challenges with automatic reconnection, as existing solutions require complex and time-consuming reconnection processes when the terminal is disconnected, such as when a user leaves home, leading to poor user experience.
Innovation Solution
A dual-mode Bluetooth terminal method that sends a BLE pairing advertisement message with a fixed advertisement address to establish a stable connection, allowing for automatic reconnection and improved user experience by simplifying the reconnection process and extending the transmission distance and directionality of the Bluetooth signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a terminal uses Bluetooth to control a household appliance, then wireless control capability is improved, but automatic reconnection fails when the terminal is disconnected
Solution Approach 1:
The patent applies preliminary action by storing the advertisement ID and connection parameters in the terminal before disconnection occurs. When the terminal reconnects, it uses these pre-stored parameters to automatically reestablish the Bluetooth connection without requiring manual intervention, thus achieving automatic reconnection while maintaining wireless control capability
2Reliability
If the terminal reconnects to the household appliance after disconnection, then connection is restored, but the reconnection process is complex and time-consuming
Solution Approach 1:
The patent stores the advertisement ID, device name, and connection parameters in advance during the initial pairing process. When reconnection is needed, the terminal retrieves these pre-stored parameters and directly initiates reconnection using them, bypassing the need for manual device discovery and pairing, thus significantly reducing reconnection time and complexity
Solution Approach 2:
The patent uses the previously stored advertisement ID and connection parameters as a copy of the original pairing information. Instead of performing a complete new pairing process, the terminal replicates the connection setup by reusing these stored parameters, which accelerates the reconnection process while ensuring connection reliability

AI summary
Embodiments of this application relate to the terminal field, and disclose a Bluetooth communication method and a dual-mode Bluetooth terminal, to resolve a problem that automatic reconnection cannot be implemented between a terminal and a household appliance, and a reconnection process is relatively complex and consumes a relatively long time. A specific solution includes: receiving, by a first dual-mode Bluetooth terminal, first input of a user; sending a first BLE pairing advertisement message in response to the first input, where an address type in the first BLE pairing advertisement message is public, an advertisement address in the first BLE pairing advertisement message is a fixed advertisement address, and the first BLE pairing advertisement message carries an identifier used to indicate that the first dual-mode Bluetooth terminal does not support BR/EDR; receiving, by the first dual-mode Bluetooth terminal, second input of the user; entering a conventional Bluetooth discoverable mode in response to the second input; receiving a paging message; and sending a paging response in response to the paging message, where the paging response carries a MAC address of the first dual-mode Bluetooth terminal, and the first input is different from the second input.
