(a6) connecting the Bluetooth host with the Bluetooth slave, sending a request to be paired by the Bluetooth host, and if the host is powered off within a specified time T2 after connection, returning to the step (a 1); if not, pairing fails.
9. A connection pairing method of Bluetooth slaves is characterized by comprising the following steps:
(b1) the Bluetooth slave computer is electrified, a broadcast packet is initiated, the broadcast packet comprises electrifying information, a pairing state and pairing information, the electrifying information is the time of just electrifying and maintaining T1, and if the Bluetooth master computer is connected within the specified time T1 after electrifying, the step (b2) is executed; if no Bluetooth host is connected, the pairing is failed;
(b2) the Bluetooth slave waits for receiving a request initiated by the host, wherein the request comprises a request to be paired and a pairing request, and if the request to be paired is received, the step (b3) is executed; if the pairing request is received, establishing pairing, updating the pairing state in the broadcast packet to be paired, and changing the pairing information into a host machine MAC address; if the request is not received, the connection is kept;
(b3) Changing the pairing state in the broadcast packet to be paired, wherein the pairing information is a host MAC address, the changed pairing state and the pairing information maintain T6 time, and T6 is at least T2+ T3; judging whether the connection is disconnected within a specified time T2 after the connection, if the connection is disconnected, initiating a broadcast packet, and executing the step (b 4); if the connection is not disconnected, the connection is kept;
(b4) whether a host is connected or not is judged within a predetermined time T3 after disconnection, if yes, return is made (b2), and if no host is connected, pairing is failed.
10. A Bluetooth connection pairing method is characterized by comprising the following steps:
(c1) the Bluetooth host and the Bluetooth slave are powered on within a T1 time period; the method comprises the steps that a Bluetooth slave computer is powered on and then launches a broadcast packet, the broadcast packet comprises power-on information, a pairing state and pairing information, and the Bluetooth master computer is powered on and then scans;
(c2) the Bluetooth host scans the broadcast packet, is connected with the Bluetooth slave, and sends a request to be paired to the Bluetooth slave, the Bluetooth slave changes the pairing state in the broadcast packet to be paired, changes the pairing information to be the MAC address of the Bluetooth host, maintains the changed pairing state and the pairing information for T6 time, and T6 is at least T2+ T3;
(c3) powering off the Bluetooth host within the specified time T2 after connection, initiating the broadcast packet by the Bluetooth slave, powering on again within the specified time T3 after power off, and scanning and reconnecting the broadcast packet by the Bluetooth host; judging the pairing state and the pairing information in the broadcast packet, if the pairing state is to be paired, matching the pairing information with the Bluetooth host, initiating a pairing request by the Bluetooth host to complete pairing, updating the pairing state in the broadcast packet to be paired by the Bluetooth slave, and changing the pairing information into a host MAC address; otherwise, the pairing fails.
