Abstract:
Disclosed are a communication device, a communication method, and a communication system. The communication system includes a communication device configured to determine a device to function as a group owner (GO) device from the communication device and a counterpart communication device communicating with the communication device and transmit information indicating which one of the communication device and the counterpart communication device is the GO device to the counterpart communication device, and the counterpart communication device configured to receive the information indicating which one of the communication device and the counterpart communication device is the GO device from the communication device and transmit, in response to receiving the information, a signal for agreeing to the information indicating which one of the communication device and the counterpart communication device is the GO device to the communication device.
Abstract:
Disclosed is a communication apparatus including: a first communicator configured to connect with an external device by a first communication mode; a second communicator configured to connect with the external device by a second communication mode different from the first communication mode; and a controller configured to control the first communicator to connect with the external device by the first communication mode, control the first communicator to obtain connection information of the second communication mode from the external device, control the second communicator to be connected to the external device by the second communication mode based on the connection information, and control at least one of the first communicator and the second communicator to transmit data to the external device.
Abstract:
An image forming apparatus is provided. The apparatus includes an integrated sensing unit, which includes an optical sensor including a light emitting part and a light receiving part to receive light emitted from the light emitting part, and an actuator which selectively blocks light to be received by the light receiving part. The actuator includes a shaft member that is elastically supported in one rotation direction, a light blocking member that is mounted on the shaft member and is selectively positioned between the light emitting part and the light receiving part, and a first contact member and a second contact member distanced from each other on the shaft member.
Abstract:
An electronic apparatus for supporting wireless peer to peer (P2P) communication with an external apparatus is provided, that includes a communicator configured to transmit and receive a signal for performing discovery and group formation, and a controller configured to transmit a first preferred channel list including a channel number indicating at least one channel pre-established among a plurality of channels available as an operating channel, to the external apparatus, to select one channel number from at least one channel number included in a second preferred channel list and the channel number included in the first preferred channel list in response to the second preferred channel list being received from the external apparatus as an operating channel with the external apparatus.
Abstract:
An electronic apparatus performing wireless peer-to-peer (wireless p2p) connection with an external device is provided. The electronic apparatus may include a communicator comprising communication circuitry, a microphone configured to receive a user voice input and a processor configured to control the communication circuitry to select the external device as a target device for the wireless p2p connection in response to the voice data received from the external device in a process of probing for the wireless p2p connection being consistent with voice data input through the microphone.
Abstract:
