Information processing device, communication method, and communication system

Abstract

An information processing device includes: an information acquisition unit which acquires information; and a communication unit which communicates with an external device via near field communication. The communication unit divides data of the information into a plurality of blocks, each including a plurality of packets, transmits the plurality of blocks with a first characteristic provided with a property of read with no acknowledge, and receives a receiving result of the blocks in the external device, with a second characteristic provided with the property of write with acknowledge.

What is claimed is: 
     
         1 . An information processing device comprising:
 an information acquisition unit which acquires information; and   a communication unit which communicates with an external device via near field communication;   wherein the communication unit divides data of the information into a plurality of blocks, each including a plurality of packets, receives the plurality of blocks with a first characteristic provided with a property of write with no acknowledge, and transmits a receiving result of the blocks with a second characteristic provided with the property of read with acknowledge.   
     
     
         2 . The information processing device according to  claim 1 , wherein
 the communication unit transmits a sequence number corresponding to a packet that fails to be received, of the plurality of packets included in the blocks that are transmitted, with the second characteristic as the receiving result.   
     
     
         3 . The information processing device according to  claim 1 , wherein
 if the communication unit transmits a sequence number indicating a packet of the plurality of packets included in the blocks that are received, with the second characteristic as the receiving result, the communication unit receives the plurality of packets again, starting with the packet corresponding to the sequence number.   
     
     
         4 . The information processing device according to  claim 1 , wherein
 the communication unit receives a communication speed change instruction with a fourth characteristic provided with the property of write with acknowledge, changes a communication speed on the basis of the communication speed change instruction that is received, and transmits a communication speed change completion notification with a fifth characteristic provided with the property of read with acknowledge.   
     
     
         5 . The information processing device according to  claim 1 , wherein
 the information includes at least one type of biological information, of pulse rate, number of steps taken, calorie expenditure, calorie intake, mental stress information, and sleep information.   
     
     
         6 . A communication method comprising:
 acquiring information;   dividing data of the information into a plurality of blocks, each including a plurality of packets;   receiving the plurality of blocks from an external device via near field communication, with a first characteristic provided with a property of write with no acknowledge; and   transmitting, to the external device, a receiving result of the blocks with a second characteristic provided with the property of read with acknowledge.   
     
     
         7 . A communication system comprising:
 a first information processing device which acquires information; and   a second information processing device which communicates with the first information processing device via near field communication;   wherein the first information processing device divides data of the information into a plurality of blocks, each including a plurality of packets, and transmits the plurality of blocks to the second information processing device, with a first characteristic provided with a property of write with no acknowledge;   the second information processing device receives the plurality of blocks with the first characteristic and transmits, to the first information processing device, a receiving result of the blocks with a second characteristic provided with the property of read with acknowledge, and   the first information processing device receives the receiving result with the second characteristic.
