a smart automatic communication method and system are introduced . the method applies to a first electronic device and a second electronic device . the first electronic device has a first near field communication chip and a first far field communication chip . the second electronic device has a second near field communication chip and a second far field communication chip . the first electronic device generates a communication packet having therein a communication setup file . the first electronic device moves toward the second electronic device until the first near field communication chip can trigger the second near field communication chip within a short distance . the communication packet is sent from the first electronic device to the second electronic device . the second electronic device analyzes the communication packet to obtain the communication setup file , thereby creating a first far field communication path between the first and second far field communication chips .
