A method for transmitting and receiving data between nodes, a plurality of the nodes each performing a periodical standby operation at a specific interval, the method for transmitting and receiving data comprising: a detecting step of detecting a communicable response node that is performed by a request node; a consecutive transmitting step of consecutively transmitting notice information representing data transmission timing to the response node for a plurality of number of times to extend over about one period of the periodical data reception standby operation of the response node at a predetermined interval by using the request node; a notice standby step of performing a standby operation for data according to the data transmission timing represented in the notice information that is performed by the response node receiving the notice information within the periodical standby operation; a determining step of determining whether or not a data size of transmission target data is equal to or less than a transmittable data size that is performed by the request node; a dividing step of dividing the transmission target data having a size larger than the transmittable data size into a plurality of pieces of intermediate data each having a data size being equal to or less than the transmittable data size that is performed by the request node; a transmission data generating step of generating a plurality of pieces of transmission data by adding a division header to each of the plurality of pieces of intermediate data that is performed by the request node; a notice transmitting step of transmitting the plurality of pieces of transmission data to the response node according to the data transmission timing represented in the notice information that is performed by the request node; a notice receiving step of receiving the transmission data transmitted from the request node according to the notified data transmission timing that is performed by the response node; and a restoring step of restoring the transmission target data by integrating the plurality of pieces of the transmission data that are received based on information of the division headers that is performed by the response node. a detecting step of detecting a communicable response node that is performed by a request node; a consecutive transmitting step of consecutively transmitting notice information representing data transmission timing to the response node for a plurality of number of times to extend over about one period of the periodical data reception standby operation of the response node at a predetermined interval by using the request node; a notice standby step of performing a standby operation for data according to the data transmission timing represented in the notice information that is performed by the response node receiving the notice information within the periodical standby operation; a determining step of determining whether or not a data size of transmission target data is equal to or less than a transmittable data size that is performed by the request node; a dividing step of dividing the transmission target data having a size larger than the transmittable data size into a plurality of pieces of intermediate data each having a data size being equal to or less than the transmittable data size that is performed by the request node; a transmission data generating step of generating a plurality of pieces of transmission data by adding a division header to each of the plurality of pieces of intermediate data that is performed by the request node; a notice transmitting step of transmitting the plurality of pieces of transmission data to the response node according to the data transmission timing represented in the notice information that is performed by the request node; a notice receiving step of receiving the transmission data transmitted from the request node according to the notified data transmission timing that is performed by the response node; and a restoring step of restoring the transmission target data by integrating the plurality of pieces of the transmission data that are received based on information of the division headers that is performed by the response node.
