In the Wireless Display and Wireless touch system of mobile phone, with a pair of of Bluetooth chip come transmitting cell-phone main part with
The low-speed bidirectional data of the parts LCD and TP, if just establishing bluetooth connection, bluetooth response before data or instruction transmission
Time can be long, generally has 2 ~ 3 seconds Bluetooth transmission time delays, user experience bad.In order to improve bluetooth response speed, need
A kind of blue-tooth intelligence interconnection mechanism ensures that this is constantly in connection status to Bluetooth chip, after successful connection if without data or
Instruction, which will be transmitted, just enters low-power consumption standby state, and state of activation is come back to when having data or instruction needs transmission.It is in
When connection status, the propagation delay time of bluetooth is usually no more than 0.5 second.
In practical application, in the Wireless Display and Wireless touch system of mobile phone, the bluetooth of mobile phone body part is defined
Chip is " bluetooth A ", that is, the first bluetooth, has specific bluetooth title, such as " XXX wireless screens host ".Define LCD and
The Bluetooth chip of the parts TP is " bluetooth B ", that is, the second bluetooth, with specific bluetooth title, such as " XXX wireless screens ",
May occur multiple " bluetooth B " simultaneously, i.e. user may have polylith LCD and TP, can replace at any time, and LCD and the parts TP can
With independent switching on and shutting down.
When booting, " bluetooth A " and " bluetooth B " can be automatically switched on." bluetooth B " can be in can discoverable mode, broadcast is special
Fixed bluetooth title such as " XXX wireless screens " is connected until being established with some " bluetooth A ".
In step s 200, the Bluetooth broadcast near the first bluetooth inquiry and corresponding Bluetooth received signals intensity is detected
Value, inquires at least one second bluetooth, and the Bluetooth received signals intensity value for judging whether there is the second bluetooth is more than signal strength
Threshold value, if it has, then the first bluetooth sends connection request signaling to second bluetooth establishes connection, and record pair with the second bluetooth
The Bluetooth address answered.
Specifically, " bluetooth A "（Namely the first bluetooth）Neighbouring conventional Bluetooth equipment can be inquired and detect bluetooth and connect
Receive signal strength RSSI (Received Signal Strength Indication) value, until with some " bluetooth B "（Also
It is the second bluetooth）Establish connection." bluetooth B " is in can discoverable mode and specific second bluetooth title of broadcast.Due to second
The possible more than one of bluetooth when for example user replaces the display portion of mobile terminal, or around has multiple of the present invention
When mobile terminal, then when the neighbouring conventional Bluetooth equipment of " bluetooth A " inquiry and Bluetooth received signals intensity RSSI value is detected,
" bluetooth A " inquires " the bluetooth B " of one or more broadcast particular bluetooth titles, then judges whether that there are one " bluetooth B "
RSSI value is more than signal strength threshold, if it has, then " bluetooth A " is built to " bluetooth B " transmission " connection request " signaling and " bluetooth B "
Vertical connection, and record the Bluetooth address for being somebody's turn to do " bluetooth B ".
Further, the step S200 is specifically included：
Bluetooth broadcast near S201, the first bluetooth inquiry simultaneously detects corresponding Bluetooth received signals intensity value；
S202, judge whether the first bluetooth inquires the corresponding bluetooth title of at least one second bluetooth, if it has, then holding
Row step S203；If it has not, then return to step S201；
S203, the Bluetooth received signals intensity value for judging whether there is the second bluetooth are more than signal strength threshold, if it has, then
Execute step S204；If it has not, then return to step S201；
S204, the first bluetooth send connection request signaling to second bluetooth and establish connection, and record pair with the second bluetooth
The Bluetooth address answered.
Specifically, referring to Fig. 2, Fig. 2 is the Bluetooth interconnection method Application Example of mobile terminal provided by the invention
Method flow diagram, in practical application, the intelligent interconnection process of " bluetooth A " and " bluetooth B " are as shown in Figure 2.It is " blue when booting
Tooth A " and " bluetooth B " can be automatically switched on." bluetooth B " can be in can discoverable mode, broadcast specific bluetooth title, such as " XXX
Wireless screen " is connected until being established with some " bluetooth A "." bluetooth A " can inquire neighbouring conventional Bluetooth equipment and detect bluetooth
Received signal strength RSSI (Received Signal Strength Indication) value is established until with some " bluetooth B "
Connection.
When " bluetooth A " inquires " the bluetooth B " of one or more broadcast particular bluetooth titles.If there are one " bluetooths
The RSSI value of B " is more than threshold values F（Namely signal strength threshold）, " bluetooth A " to " bluetooth B " transmission " connection request " signaling,
" bluetooth B " is somebody's turn to do to " bluetooth A " transmission " connection is replied " signaling, " bluetooth A " is connected with " bluetooth B " foundation is somebody's turn to do, and recording should " bluetooth
The Bluetooth address of B ".
Further, the step S203 further includes：
S231, the Bluetooth received signals intensity value for judging whether there is the second bluetooth are more than signal strength threshold, if it has, then
Execute step S204；If it has not, thening follow the steps S232；
S232, the second bluetooth that the first bluetooth had connected is judged whether there is, if it is, S204 is thened follow the steps, if
It is no, then return to step S201.
Specifically, please continue to refer to Fig. 2, if being more than " the bluetooth B " of threshold values F without RSSI value, then judgement is
It is no have " bluetooth B " be " bluetooth A " last time connection（Or it had connected）Bluetooth equipment, as long as there are one " bluetooth B " be last time connect
The bluetooth equipment connect, i.e. its Bluetooth address are the Bluetooth address recorded when last time successful connection, and " bluetooth A " is sent out to " the bluetooth B "
" connection request " signaling is sent, " bluetooth B " is somebody's turn to do to " bluetooth A " transmission " connection is replied " signaling, " bluetooth A " and is somebody's turn to do " bluetooth B " foundation
Connection, and record the Bluetooth address for being somebody's turn to do " bluetooth B ".
Setting about bluetooth RSSI threshold values F.In principle, bluetooth RSSI value that recipient receives with it is certain apart from existing
Linear relationship, i.e. bluetooth RSSI value reduce with the increase of two bluetooth equipment distances.But actually since bluetooth receives and dispatches day
Line is not the blocking of complete omnidirectional antenna and equipment to Bluetooth signal itself, the bluetooth received on same distance different directions
RSSI value has larger difference.In hardware design, need to ensure to be assemblied in one when mobile phone body part and the parts LCD and TP
When rising, the antenna of the antenna close " bluetooth B " of " bluetooth A ", to the RSSI of guarantee " bluetooth A " is received at this time " bluetooth B "
It is worth sufficiently large, such as -30dBm.When LCD and TP is partially away from mobile phone body part, when such as 50 centimetres or more separate, " bluetooth A "
The RSSI value of " the bluetooth B " that receives is generally less than -50dBm.Therefore, it is possible to by setting bluetooth RSSI threshold values F（As-
30dBm）Come filter out which equipment be user wish connection equipment, that is, be assembled to or against mobile phone body part LCD and
Bluetooth equipment on TP." bluetooth A " meeting preferential attachment RSSI is more than " the bluetooth B " of threshold values F, i.e. user wishes that connected is set
It is standby, prevent accidentally to connect, ensures safety.For " the bluetooth B " on new LCD and TP, only its bluetooth RSSI value is more than valve
It can just be connected by mobile phone body part " bluetooth A " when value F, for " the bluetooth B " on the LCD and TP of last time newly connection, when
It can be connected at a distance by " the bluetooth A " of mobile phone body part when being more than the equipment of threshold values F without other bluetooth RSSI values, to indigo plant
Tooth RSSI value does not require, i.e., " bluetooth A " only has found that " the bluetooth B " of last time newly connection can be established a connection at once.
In step S300, after successful connection when there is no data or instruction needs transmission, the first bluetooth and second indigo plant
Tooth enters low-power consumption standby state, and when having data or instruction needs transmission, the first bluetooth comes back to sharp with second bluetooth
State living.Specifically, if no data or instruction, which will be transmitted, just enters low-power consumption standby state, when there is number after successful connection
According to or instruction need transmission when come back to state of activation.In this way, the blue-tooth intelligence interconnection mechanism of the present invention makes indigo plant after booting
Tooth chip is constantly in low-power consumption connection status, although can increase by 1 ~ 2mA standby currents, is influenced on whole standby current
Less, and it can effectively improve the response speed of bluetooth data transmission and control instruction.
Preferably, if " bluetooth A " connect disconnection with " bluetooth B ", " bluetooth B " can be again introduced into can discoverable mode, extensively
Specific bluetooth title is broadcast, is connected until being established with some " bluetooth A "." bluetooth A " inquires neighbouring conventional Bluetooth equipment again
And Bluetooth received signals intensity RSSI value is detected, it is connected until being established again with some " bluetooth B ".
Such blue-tooth intelligence interconnection process may be implemented " bluetooth A " and be connect automatically with " bluetooth B " booting, after disconnection certainly
Dynamic reconnection can also realize that " the bluetooth B " with bluetooth RSSI value more than threshold values F establishes connection automatically when there is multiple " bluetooth B ".
When user wants to replace LCD and TP, as long as opening new LCD and TP and being assembled into mobile phone body part, while passing through pass
Old LCD and TP are closed, or restarts mobile phone body part, or old LCD and TP is disconnected partially away from the methods of mobile phone body part
The bluetooth connection that Kaiyuan is come, then " bluetooth B " foundation automatically of " the bluetooth A " of mobile phone body part and the new parts LCD and TP
Connection.
Further, further include after the step S300：
S400, after display portion is lit, judge there is no holding for data transmission between the first bluetooth and second bluetooth
Whether the continuous time is more than time threshold, if being more than, the first bluetooth sends empty data packet every first time and gives second bluetooth,
Second bluetooth is not processed when receiving the empty data packet, so that the first bluetooth is always maintained at state of activation with second bluetooth.
Specifically, it after a pair of of Bluetooth chip successful connection, if not having data to transmit, waits for after a certain period of time just
Low-power consumption standby state can be entered, state of activation is come back to when needing transmission when there are data.Table 8 is that a pair of of Bluetooth chip is established
Connect later " propagation delay time " test result, wherein " propagation delay time " indicates that a Bluetooth chip sends empty data at GAP layers
Wrap the entire time that another Bluetooth chip receives the sky data packet；It can be waited for before one empty data packet of each transmission
One " stand-by period ", i.e., the interval time that empty data packet is sent twice.Test result is shown：When " stand-by period " was at 0 ~ 5 second
When, data transmission can be rapidly completed between two Bluetooth chips, average " propagation delay time " is about 35 milliseconds；When " stand-by period "
30 seconds when more than 5 seconds, such as in table, the data transmission period between two Bluetooth chips can increase, average " propagation delay time "
About 380 milliseconds.
Table 8
Referring to Fig. 3, Fig. 3 was more than 5 seconds when " stand-by period "（Such as 7 seconds）When, the complete machine dark screen caused by bluetooth is standby
The situation of change of electric current, i.e. Bluetooth chip are the case where state of activation and low-power consumption standby state change back and forth.Sky data every time
Bluetooth chip can keep about 5 seconds states of activation after packet sends or receives, and the complete machine dark screen standby current that is averaged is about at this time
29mA, Bluetooth chip can enter low-power consumption standby state after 5 seconds, and the complete machine dark screen standby current that is averaged drops to about at this time
7mA.Power consumption when power dissipation ratio standby mode when bluetooth state of activation increases about 22mA.
According to these characteristics of above-mentioned bluetooth：There is lower power consumption and higher transmission time delay when Bluetooth Low Energy is standby；It is blue
Tooth has relatively low propagation delay time and higher power dissipation in state of activation.In the Wireless Display and Wireless touch system of mobile phone, use
A pair of of Bluetooth chip carrys out the low-speed bidirectional data of transmitting cell-phone main part and the parts LCD and TP, in mobile phone dark screen using compared with
The Bluetooth control mechanism of low-power consumption, in the bright screen of mobile phone using the Bluetooth control mechanism of relatively low propagation delay time.
When mobile phone dark screen is standby, this is needed to Bluetooth chip without the high data of requirement of real-time and signaling to transmit,
In order to reduce the standby current of complete machine, this is to entering low-power consumption standby state after Bluetooth chip successful connection, when having data or refer to
Order needs to come back to state of activation when transmission.When user lights screen, Bluetooth transmission is needed to open the instruction of LCD, if
Bluetooth is in low-power consumption standby state at this time, then needing additionally to increase about 380 milliseconds of time to transmit this instruction, no
It crosses, since operations such as LCD power-up initializings itself need longer time, the additional transmissions time delay that bluetooth is brought is to user
Experience influence it is little, and when mobile phone dark screen is standby must assure that sufficiently low complete machine standby current.Therefore, mobile phone dark screen is standby
When, this does not make an amendment the controlling mechanism of bluetooth, that is, if no data or instruction, which will be transmitted, just enters low work(after successful connection
Standby mode is consumed, state of activation is come back to when there are data or instruction needs transmission.
After user lights LCD, at this moment user can need this to be ready to Bluetooth chip at any time by TP touch-control mobile phones
Transmit TP touch datas.The time that user clicks TP to TP output touch datas is about 45 milliseconds, i.e. the touch-control time delay of TP is big
It is approximately 45 milliseconds.It, can be in 35 milliseconds or so of time by TP touch-control numbers if bluetooth is active at this time
