SA2: bluetooth equipment waits terminal device to communicate with connection；
SA3: whether confirmation terminal device connect with bluetooth devices, if then entering step S1, if otherwise entering step
SA4；
SA4: whether confirmation broadcast is overtime, if then entering step SA5, if otherwise return step SA2；
SA5: bluetooth equipment, which is closed, broadcasts and enters suspend mode.
7. a kind of Bluetooth encryption communication means according to claim 6, it is characterised in that: the step S4 includes:
S41: after the completion of communication, it is confirmed whether to update current secret key, if then entering step S5, if otherwise entering step S42；
S42: terminal device and bluetooth equipment are disconnected and being communicated to connect, then return step SA1.
8. a kind of Bluetooth encryption communication system, it is characterised in that: including bluetooth equipment, terminal device and server；
The bluetooth equipment, the current secret key for being preset with a current secret key and answering with the current secret key pair index；For passing through
Current secret key and terminal device carry out coded communication；
The server, is preset with multiple secret keys and one-to-one multiple secret keys index respectively with multiple secret keys；
The terminal device for obtaining current secret key index to bluetooth equipment, and is indexed to server using current secret key and is obtained
Current secret key corresponding with current secret key index is taken, then carries out coded communication using current secret key and bluetooth equipment.
9. a kind of Bluetooth encryption communication system according to claim 8, it is characterised in that: the terminal device is also used to
New key and new key index are obtained to server, to update the secret key and secret key index of bluetooth equipment, is formed new current close
Spoon and current secret key index.
10. a kind of Bluetooth encryption communication system according to claim 8 or claim 9, it is characterised in that: the bluetooth equipment includes
Door-locking system and bluetooth transparent transmission system, the door-locking system are connect with bluetooth transparent transmission system communication, and the bluetooth transparent transmission system is used
