Self-adaptive Bluetooth pairing method

The invention provides a self-adaptive Bluetooth pairing method, which mainly comprises the following steps of: (1) loading Bluetooth equipment information, namely configuring a file partition on a storage medium, and loading paired Bluetooth equipment information and pairing management information of paired Bluetooth equipment to a memory; (2) initializing system pairing management information; (3) waiting for pairing; (4) pairing operation: (4.1) judging whether a pairing upper limit is reached or not; (4.2) a pairing upper limit is self-adapted according to the system pairing management information; (4.3) judging whether the pairing is successful or not; (4.4) generating equipment pairing management information; (4.5) recording the information of the Bluetooth device; and (5) connection operation, that is, the unpaired Bluetooth devices can be connected only after being paired, and the paired Bluetooth devices can be directly connected. The upper limit can be dynamically calculated according to the memory
