Description
Technical field
The present invention relates to communication technical field, and in particular to a kind of Bluetooth communication method, device and bluetooth equipment.
Background technology
In bluetooth equipment and mobile terminal normal interaction process, it should be the application layer progress of bluetooth equipment and mobile terminal
Data communicate.Data when bluetooth equipment and mobile terminal proper communication are moved towards：The application layer of mobile terminal to oneself
Underlying protocol stack sends the underlying protocol stack bluetooth connection bluetooth of the control instruction, then mobile terminal of " bluetooth connection bluetooth equipment "
Equipment, so far, the communication link of " mobile terminal application layer → mobile terminal underlying protocol stack → bluetooth equipment " are established.But
In practical application, once the distance between bluetooth equipment and mobile terminal have exceeded bluetooth connection distance range, then bluetooth equipment
It will be disconnected with mobile terminal.Because mobile terminal possesses Auto-reconnect function, when bluetooth equipment and mobile terminal disconnect
Afterwards, mobile terminal will actively connect bluetooth equipment.But the underlying protocol stack of part mobile terminal do not obtain mobile terminal should
The bluetooth connection sent with layer is instructed with regard to automatic connection of Bluetooth equipment, and the communication link now established is " mobile terminal bottom is assisted
Discuss stack → bluetooth equipment ", and mobile terminal underlying protocol stack can't report itself and bluetooth to the application layer of mobile terminal
The connection status of equipment.When the Bluetooth address that the application layer of mobile terminal is reused before disconnecting goes to call mobile terminal bottom association
Stack bluetooth protocol repertory object is discussed, when request re-establishes bluetooth connection with bluetooth equipment, due to the underlying protocol stack of mobile terminal
Bluetooth connection (the i.e. Bluetooth address of the bluetooth equipment bluetooth with mobile terminal underlying protocol stack has been established with bluetooth equipment
Addresses match), the application layer of mobile terminal will be unable to retrieve the Bluetooth address of bluetooth equipment, cause the application of mobile terminal
Layer can not establish bluetooth connection with bluetooth equipment, and then cause bluetooth equipment can not be communicated with mobile terminal application layer, i.e.,
There is mobile terminal application layer and bluetooth devices abnormal problem.
In the prior art, in order to solve the above problems, the method routinely used is the indigo plant of hand switch machine mobile terminal
Tooth, the operation of this method is relatively complicated, wastes more time during user's hand switch hand set bluetooth, directly affects bluetooth and set
Standby reconnection function, reduces Consumer's Experience.
