A communication device includes a control unit that establishes a wireless communication between a communication unit and an external device by using setting data received from the external device. The device also includes a data processing unit that stores the setting data in a storage unit before the wireless communication is released. Further, the device includes a power input unit that receives power from outside. A communication releasing unit releases the wireless communication between the communication unit and the external device. The control unit uses the setting data stored in the storage unit at a time of re-performing a wireless communication between the communication unit and the external device. The communication releasing unit does not release the wireless communication when the power is being supplied via the power input unit even when a predetermined time has passed.

Wireless communication system, wireless communication device, wireless communication method and program

A wireless communication method includes receiving from an other wireless communication device, by using a non-contact communication method, specification data that indicates a communication function of the other wireless communication device. The wireless communication method also includes converting, if the specification data does not correspond to a wireless communication whose communication speed is faster than a communication speed of the non-contact communication method, a data format of transmission data that is transmitted to the other wireless communication device to a data format that reduces a data volume of the transmission data. Additionally, the wireless communication method includes transmitting, by the non-contact communication method, to the other wireless communication device, the transmission data whose data format was converted to reduce the data volume of the transmission data.

Wireless communication system, wireless communication device, program, and wireless communication method

A communication device includes a communication unit that performs a wireless communication with an external device. The communication device also includes a control unit that establishes the wireless communication between the communication unit and the external device by using setting data received from the external device. Further, the communication device includes a data processing unit that stores the setting data in a storage unit before the wireless communication is released. The communication device additionally includes a power input unit, and a communication releasing unit that releases the wireless communication between the communication unit and the external device. The control unit uses the setting data stored in the storage unit at a time of re-performing a wireless communication between the communication unit and the external device. The communication releasing unit releases the wireless communication when power is not being supplied via the power input unit.

A first communication unit performs a non-contact communication with an external device and receives setting data from the external device. A second communication unit performs a wireless communication with the external device. A control unit establishes the wireless communication between the second communication unit and the external device by using the setting data. A data processing unit stores the setting data in a storage unit before the wireless communication is released. A communication releasing unit releases the wireless communication. The control unit uses the setting data stored in the storage unit at a time of re-performing a wireless communication between the second communication unit and the external device. The communication releasing unit releases the wireless communication when the power is not being supplied via a power input unit to which power is input from outside.

Provided is an information processing apparatus including a first and second communication units: the first for non-contact communication with a first/second external apparatus through a first path; and the second for communication with the first/second external apparatus through a second path. The apparatus also includes a unit for controlling the second communication unit to start communication with the second external apparatus through the second path, by a request for such communication transmitted from the second external apparatus to the first communication unit. The apparatus also includes a unit for managing information to be held when the request is received. The information indicates a state of communication with the first external apparatus through the second path at the reception of the request. Under the control, communication with the first communication unit specified by the information starts through the second path, where communication with the second external apparatus has been terminated.

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

A wireless communication method implemented by a wireless communication device includes performing a non-contact communication with an other wireless communication device. The method also includes receiving predetermined setting data from the other wireless communication device. Further, the method includes establishing a wireless connection with the other wireless communication device by using the predetermined setting data. The method additionally includes storing the predetermined setting data in a storage medium before the wireless connection is released. In addition, the method includes releasing the wireless connection. The method further includes establishing a wireless reconnection with the other wireless communication device by using the predetermined setting data stored in the storage medium. The wireless connection is not necessarily released by the wireless communication device while power is being supplied from outside.

There is provided a wireless communication device that includes a first communication portion that performs non-contact communication with an other wireless communication device and receives unit specific data indicating the other wireless communication device's communication function; a second communication portion that can communicate wirelessly faster than the first communication portion; a determination portion that determines, based on the unit specific data, whether the other wireless communication device's communication function is compatible with the second communication portion; and a format conversion portion that converts a format of transmission data that is transmitted to the other wireless communication device to a format that reduces the volume of the transmission data. If the determination portion determines that the other wireless communication device's communication function is not compatible with the second communication portion, the first communication portion transmits the transmission data to the other wireless communication device in the converted data format.
