Communication device, communication method, and storage medium

A communication method performed by a device comprising:

• receiving a packet containing first information indicating a structure type of data from another device extracting the first information from the packet;
• communicating data corresponding to the first information;
• receiving second information relating to communication control from the other device;
• generating one or more packets to be transmitted to the other device based on the first information when the second information has a first value;
• waiting to receive another packet from the other device when the second information has a second value;
• storing a plurality of distinguishing information for distinguishing a plurality of features and a plurality of setting values of the plurality of features;
• generating a predetermined number of packets when the second information has the first value, each of the predetermined number of packets containing setting values of one or more features;
• and
• analyzing a predetermined number of packets received from the other device based on the first information when the second information has the second value.

A non-transitory computer-readable storage medium for storing a computer program comprising a sequence of instructions which, when executed by a computer included in a device, cause the device to perform steps of:

• receiving a packet containing first information indicating a structure type of data from another device;
• extracting the first information from the packet;
• communicating data corresponding to the first information;
• receiving second information relating to communication control from the other device;
• generating one or more packets to be transmitted to the other device based on the first information when the second information has a first value;
• waiting to receive another packet from the other device when the second information has a second value;
• storing a plurality of distinguishing information for distinguishing a plurality of features and a plurality of setting values of the plurality of features;
• generating a predetermined number of packets when the second information has the first value, each of the predetermined number of packets containing setting values of one or more features;
• and
• analyzing a predetermined number of packets received from the other device based on the first information when the second information has the second value.
