File transmission/reception device and control method of file transmission/reception device
First Claim
1. A control method of a file transmission/reception device, the method comprising:
- 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, cutting off the connection at the second communication layer with the opposing device;
determining 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;
switching the file transmission/reception device to the decided mode; and
performing transmission, reception, or transmission/reception of a file with the opposing device and the file transmission/reception device in the decided mode;
wherein the determining includes;
checking whether the opposing device is compliant with a bidirectional communication operation,if the opposing device is compliant with the bidirectional communication operation, deciding the mode such that the file transmission/reception device performs a bidirectional communication process,if the opposing device is not compliant with the bidirectional communication operation, deciding the mode such that the file transmission/reception device performs a 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.
