(2) mobile phone connects in the set time section of user's setting every day, once connect, just no longer disconnects, unless mobile phone initiatively disconnects away from Intelligent clock or user, or user is switched to other connection modes.

(3) select the fixed time of user's setting to attempt being connected with Intelligent clock, but in integral point and least bit moment, will can shield some time point according to the situation of oneself, to connect and after completing communication, both sides exit connection each.

User is after amendment the arranging of mobile phone, if will come into force, can press " opening bluetooth " button on Intelligent clock panel, after this key is pressed, Intelligent clock starts bluetooth at once, and then mobile phone is connected with Intelligent clock, automatically revises setting.Otherwise this setting will just come into force by the time after the upper once connection of both sides.

3 bluetooth connected modes

The Blue-tooth communication method that mobile phone A PP indicates mobile phone to support: LE low-power consumption bluetooth or traditional B R/EDR pattern.

Implementation:

With which kind of bluetooth mode communicate with Intelligent clock, depend on mobile phone A PP application program completely.Mobile phone A PP program can search the bluetooth mode that this mobile phone is supported automatically, then selects which kind of pattern intelligently.Without the mobile phone of LE pattern, its APP can only select single traditional B R/EDR pattern to communicate with Intelligent clock, and can with mobile phone two kinds of patterns of BLE pattern, but adopt which kind of pattern on earth, determined by APP application program intelligence, when the music file that transmission data volume is larger, APP can adopt traditional B R/EDR pattern, when other application that conveying capacity is less, APP can adopt LE low-power consumption mode, greatly can reduce the communication power consumption of both sides like this, the service time that Intelligent clock is once charged is longer.

Each connection procedure of mobile phone and Intelligent clock is as follows:

In two kinds of situation:

The first, is if adopt conventional Bluetooth BR/EDR mode:

1st step, Intelligent clock opens the broadcast that bluetooth sends " can connect ", " can find ".

2nd step, mobile phone A PP opens bluetooth scanning Intelligent clock, if the First Contact Connections of mobile phone and Intelligent clock, then after discovery Intelligent clock bluetooth device address, stops scanning, and remembers the bluetooth device address BD_ADDR of Intelligent clock.

3rd step, mobile phone A PP sends " key connection " request by this Bluetooth address to Intelligent clock, consults to use " key is connected " mode with Intelligent clock.Namely this key is " pairing password ", preserves in advance inside Intelligent clock, can be revised after both sides connect by mobile phone A PP.

4th step, if both sides be first time connect, this face of mobile phone pairing cryptographic consumer also do not input, Intelligent clock then loopback not by the response of " key connection ".

5th step, mobile phone is when first time attempts " key connection ", receiving Intelligent clock can not the information of " key connection ", then " pairing request " is sent to Intelligent clock, and require that user inputs " pairing password " on mobile phone, this pairing password is preserved as connection key below on mobile phone, and is sent to Intelligent clock.

6th step, Intelligent clock finds that pairing password is correct, then record the Bluetooth address of mobile phone, and sends " successful matching " response to mobile phone, so far both sides' successful matching.

7th step, mobile phone sends " creating key to connect " request to Intelligent clock.

8th step, Intelligent clock is then preserved the key that the mobile phone of successful matching is just now sent, and then sends " establishment key " success response, does not just need to have matched when after this connecting again.

9th step, then both sides start to exchange data or order.

10th step, both data process.

11st step, communicates complete, and mobile phone sends " disconnecting " request, and both sides disconnect.If Intelligent clock more than 30 seconds, does not still receive " disconnecting " request that mobile phone is sent, then initiatively disconnects, and close blue tooth interface power supply after communication.

12nd step, after this connects each time, and mobile phone no longer needs to scan bluetooth equipment, only needs the Intelligent clock Bluetooth address according to having preserved and pair-wise key, attempts sending " key link " request to Intelligent clock.

13rd step, APP is owing to having consulted with Intelligent clock by " key is connected " mode during First Contact Connections, and simultaneously this face of Intelligent clock also saves the key and its Bluetooth address that mobile phone sends, so do not need again to send pairing request to Intelligent clock.

As long as mobile phone sends key connection request to Intelligent clock, and carry correct key in the request secretly, wait for that Intelligent clock returns and respond; Intelligent clock this look like fruit receive, just can send the response that runs succeeded.

14th step, both sides start again to transmit data

15th step, after disconnect.The like.。。。

The second, adopts LE low-power consumption bluetooth approach:

Mobile phone in LE Bluetooth link layer as main equipment, Intelligent clock in LE link layer as from equipment.On bluetooth attribute protocol layer, mobile phone is as client, and Intelligent clock is as server.

1st step, Intelligent clock sends the broadcast of " can connect ", " can find ".

2nd step, mobile phone A PP opens bluetooth scanning Intelligent clock, if the First Contact Connections of both sides, then after discovery Intelligent clock Bluetooth address, stops scanning, and remembers the Bluetooth address BD_ADDR of Intelligent clock, omit this step when after this again connecting.

3rd step, mobile phone initiates LE linking request event according to the Intelligent clock Bluetooth address preserved to Intelligent clock server as client.

4th step, Intelligent clock equipment enters connection status and back response after receiving LE connection request event, makes both sides all enter LE connection status.

5th step, mobile phone sends inquiry service event command to Intelligent clock, and Intelligent clock then provides service UUID and characteristic UUID.The UUID of Intelligent clock preserved by mobile phone after first time inquiry, no longer inquires about when again connecting thereafter.

6th step, mobile phone, according to the service of Intelligent clock and characteristic UUID, sends to Intelligent clock the request of reading or writing.

7th step, Intelligent clock reads or writes request event fill order according to what receive, and back response realizes exchanges data.

8th step, after communication, mobile phone sends " disconnecting " request.

9th step, Intelligent clock disconnects, and then closes bluetooth, waits for and connecting next time.

10th step, after after this connecting each time, mobile phone no longer needs the service characteristic inquiring about Intelligent clock, and the service of an Intelligent clock Bluetooth address needing basis to preserve and preservation and characteristic UUID, communicate with Intelligent clock.

11st step, Intelligent clock once connects the moment upper, again opens " can connect ", " can find " broadcast.

12nd step, mobile phone initiates LE linking request event according to the Intelligent clock Bluetooth address preserved to Intelligent clock server as client, and after Intelligent clock response, both sides enter connection status.

13rd step, in connected state, mobile phone, according to the service UUID of the Intelligent clock preserved and characteristic UUID, sends to Intelligent clock the request of reading or writing.

14th step, then intercommunication process

15th step, after communication, mobile phone sends " disconnecting " order, and Intelligent clock break link closes bluetooth, waits for and connecting next time.By that analogy
