The method that NFC is called during pairing.
Background technology
Near-field communication（NFC）Also known as wireless near field communication allows to carry out non-connect in ten centimetres between electronic equipment
Touch Point-to-Point Data Transmission exchanges data, is being developed by non-contact radio-frequency identification technology.Current near-field communication technology
It is mainly used in the public services such as mobile-phone payment and ticket, cash register.
The booting of existing printing device and Bluetooth pairing are typically all artificial manual mode, and the booting of printing device is generally
It is switched on by mechanical switch, button or long-press, Bluetooth pairing needs artificial bluetooth discovery, Password Input and with the multiple steps of equity
Suddenly, equipment search hunting time is more long, due to artificial Password Input, so will appear unpaired feelings during password pairing
Condition extends the time of bluetooth connection.
Bluetooth pairing flow generally comprises following steps：1. inquiry scan：Matched by equipment response policy is queried
Set the influence of the factors such as power, communication distance, the annoyance level of parameter and radiofrequency signal, it is possible to which hundreds of milliseconds are scanned for target
Equipment, it is also possible to which time-out was still scanned less than generally surveying within the scope of unobstructed 3 meters could inquire in 2-3 seconds in more than ten seconds
To bluetooth equipment；2. link layer connects, the Signalling exchange of pure baseband module, just completed within 100 milliseconds；3. Password Input is used
Family interface inputs PIN code, clicks and confirms that the option of pairing exists simultaneously Password Input since the time artificially inputted is unknowable
Mistake generally takes at 5-20 seconds or so；4. pairing, general 100 milliseconds or so of the order flow of pairing, the long time is not defeated
Membership sentences time-out and fails to match；5. service is established, determined depending on top service various types, it is generally time-consuming also shorter,
100 milliseconds or so.In conclusion most fast conventional Bluetooth pairing takes and probably needs 15 seconds or so, the specific time is uncontrollable, together
When there is connection time-out the case where can not connecting, it is inconvenient to use.

The uniform resource identifier URI of the print application APP installed on APP or mobile phone and the unified resource near field communications chip
Identifiers, URIs are inconsistent, then on mobile phone automatic spring using the uniform resource identifier URI near field communications chip as download address
Application APP download interface, carry out application APP download；
5）It downloads and pacifies as the application APP of download address using the uniform resource identifier URI near field communications chip
After the completion of dress, print application APP is automatically opened, and the bluetooth that print application APP is obtained near field communications chip is matched
To data and execute Bluetooth pairing connection.
As a further solution of the present invention：Uniform resource identifier URI burnings in the near field communications chip are close
On the communication chip of field.
As a further solution of the present invention：The GPO pins of the near field communications chip are separately connected power-supply system and micro-
The GPIO pins of processor.
As a further solution of the present invention：The printing device realizes that the time of Auto Power On is 500ms-1s.
As further scheme of the invention：The bluetooth of the printing device realizes that the time of automatic matching connection is little
In 2.5s.
Compared with prior art, the beneficial effects of the invention are as follows：
Auto Power On printing device may be implemented in the present invention, automatic to carry out Bluetooth pairing connection and match precisely, low-power consumption,
It is of low cost, data transmission security is stable, data-link quickly connects, function intelligence, shorten the time of booting and Bluetooth pairing,
It is easy to use.
