Step S120, the main control chip transmits the MAC address information and name information to the NFC card reader;

Step S130, the NFC card reader sends the MAC address information and name information to the NFC tag, so that when the Bluetooth device touches the NFC tag, the Bluetooth device obtains the MAC address information and name information through the NFC tag, and establishes a Bluetooth connection with the Bluetooth printer .

In some embodiments, the Bluetooth device includes a Bluetooth-enabled mobile device (such as a mobile phone, a tablet computer, etc.).

In some embodiments, the Bluetooth MAC address (Media Access Control Address) is a 48-bit unique identifier, which is used to identify the hardware address of the Bluetooth device. The MAC address is set by the manufacturer during the device manufacturing process and remains unchanged throughout the life cycle of the device. The Bluetooth protocol stipulates that the first 24 bits of the MAC address are the manufacturer ID of the device, and the last 24 bits are the device ID of the manufacturer. Sequential numbering; the name of Bluetooth is used to identify the Bluetooth device, the name of the Bluetooth device can be preset by the device manufacturer during the production process, or can be customized by the user when pairing the device; when an external Bluetooth device is paired with a Bluetooth printer , the bluetooth module in the bluetooth printer can perform bluetooth broadcast, and send the bluetooth name and MAC address to the outside, so that the bluetooth device can discover and connect to the bluetooth module, and the bluetooth device can identify and verify by obtaining the MAC address of the bluetooth module in the bluetooth printer, thus Bluetooth connection; the existing technology is to make the Bluetooth device obtain the Bluetooth name and MAC address by receiving input, which is inefficient.

Among them, when the Bluetooth device touches the NFC tag, the built-in NFC chip of the Bluetooth device will emit a high-frequency electromagnetic field , this electromagnetic field will excite a part of the circuit in the NFC tag. Since the NFC tag is passive (passive device), the NFC tag will absorb part of the electric energy from the electromagnetic field, and use this part of the electric energy to drive the internal circuit to generate reverse electromagnetic field. After certain processing, the reverse electromagnetic field can be interpreted by the NFC chip built into the mobile phone, so that it can keep working normally without embedding batteries or other independent power sources in the NFC tag.
