Embodiment Construction

[0022] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0023] see Figure 1-2 , a method for invoking NFC during the automatic power-on of the printing device and the automatic Bluetooth pairing process, the specific steps are as follows:

[0024] 1) Bring the mobile phone 1 with the near field communication module 3 close to the printing device 2, the printing device 2 detects the field strength of the near field communication through the near field communication module 3, and the GPO pin of the near field communication chip 4 in the printing device 2 outputs a low The level interrupt signal is given to the power supply system 5 and the microprocessor 6 of the printing device 2;

[0025] 2) After receiving the low-level interrupt signal, the microprocessor 6 inputs a signal to the power supply system 5 to stabilize the level on the power supply system 5, thereby enabling the printing device 2 to star...

Abstract

The invention discloses a method for calling NFC (Near Field Communication) in the automatic power-on process of printing equipment and an automatic Bluetooth pairing process. The method comprises the following specific steps that: a mobile phone is brought close to the printing equipment, the printing equipment detects the NFC field intensity, a GPO pin of an NFC chip in the printing equipment outputs a low-level interrupt signal to a power supply system and a microprocessor of the printing equipment, and the microprocessor inputs a signal into the power supply system after reception of the low-level interrupt signal to stabilize a level on the power supply system in order to power on the printing equipment; and if a uniform resource identifier (URI) configured by a printing application APP in the mobile phone is consistent with a URI in the NFC chip, the printing APP is started up automatically, and Bluetooth pairing and connection are performed after the printing APP acquires Bluetooth pairing data. Through adoption of the method, automatic power-on of the printing equipment can be realized; Bluetooth pairing connection is performed automatically; pairing is accurate; low power consumption, low cost, data transmission security and stability; rapid data link connection and smart functions are realized; the power-on and Bluetooth pairing time is shortened; and convenience is brought to use.

Description

technical field [0001] The invention relates to the technical field of high-frequency wireless communication, in particular to a method for invoking NFC during automatic booting of a printing device and automatic pairing of Bluetooth. Background technique [0002] Near Field Communication (NFC), also known as short-range wireless communication, allows non-contact point-to-point data transmission and exchange data between electronic devices within ten centimeters, and is evolved from non-contact radio frequency identification technology. At present, near-field communication technology is mainly used in public services such as mobile payment, bus tickets, and cash register. [0003] The power-on and Bluetooth pairing of existing printing devices are generally manual. The power-on of printing devices is generally done by mechanical switches, buttons or long presses. Bluetooth pairing requires multiple steps such as manual Bluetooth search, password input and pairing. Device sea...
