File transmission/reception device and control method of file transmission/reception device
First Claim
1. A file transmission/reception device comprising:
- a communication direction managing unit that, if in near field communication a conflict occurs in a connection at a second communication layer higher than a first communication layer with an opposing device, cuts off the connection at the second communication layer with the opposing device, decides a mode of the file transmission/reception device when performing a re-connection at the second communication layer via the connection at the first communication layer with the opposing device as any one mode of a master mode and a slave mode, and switches the file transmission/reception device to the decided mode; and
an application unit that performs transmission, reception, or transmission/reception of a file with the opposing device and the file transmission/reception device in the decided mode, whereinthe communication direction managing unit determines whether the opposing device is compliant with a bidirectional communication operation,if the opposing device is compliant with the bidirectional communication operation, the communication direction managing unit decides the mode such that the file transmission/reception device performs a bidirectional communication process, andif the opposing device is not compliant with the bidirectional communication operation, the communication direction managing unit decides the mode such that the file transmission/reception device performs an unidirectional communication process.

Abstract
According to one embodiment, a file transmission/reception device includes a communication direction managing unit and an application unit. The communication direction managing unit, in near field communication, cuts off a connection with an opposing device in a case where a conflict occurs with the opposing device, and, after being reconnected to the opposing device, switches the file transmission/reception device to any one mode of a master mode and a slave mode. The application unit performs transmission, reception, or transmission/reception of a file between the opposing device and the file transmission/reception device in the master mode or the slave mode in accordance with a mode specified by the communication direction managing unit.
