Abstract
The present invention relates to a near field communication device containing a ZigBee communication module circuit linking with a Bluetooth communication module. A ZigBee module is equipped with a master central processing unit (CPU) to identify N-Fi communication protocol and enable wireless communication. The master CPU is connected with a communication chip to transmit or receive packets, and includes a ZigBee memory to store the packets temporarily. Besides, the master CPU is linked with a signal conversion/transmission circuit to enable internal exchange of information packets with the Bluetooth communication module. The Bluetooth communication module has a Bluetooth master CPU to control Bluetooth communication, and is connected with a Bluetooth communication chip to transmit and receive Bluetooth-based packets. Thus, the embedded Bluetooth module can be used to connect the electronic device that includes a ZigBee module to carry out transmission of NFC signals.
