Information processing apparatus, information processing method, information processing system, and storage medium with control program stored thereon

An information processing method comprising:

• wirelessly transmitting and receiving a packet through synchronous communication to and from another apparatus;
• determining whether the transmitted packet has been received by the another apparatus;
• and
• selecting, when reception of a previously transmitted packet by the another apparatus is not confirmed, between retransmission processing for retransmitting the previously transmitted packet and non-retransmission processing for transmitting another packet instead of the previously transmitted packet depending on a content of the previously transmitted packet.

An information processing system comprising:

• a processor which executes a control program;
• and
• a radio module which wirelessly transmits and receives a packet through synchronous communication to and from another apparatus,
• the processor
• determining whether the packet transmitted from the radio module has been received by the another apparatus, and
• selecting, when reception of the previously transmitted packet by the another apparatus is not confirmed, between retransmission processing for retransmitting the previously transmitted packet and non-retransmission processing for transmitting another packet instead of the previously transmitted packet depending on a content of the previously transmitted packet.
