In a communication system including a communication apparatus and a communication terminal which are able to perform wireless communication with each other, the communication apparatus includes a first wireless communication interface conforming to a Bluetooth standard and including a plurality of antennas, and the communication terminal includes a second wireless communication interface conforming to the Bluetooth standard and one or more controllers configured to acquire angle information and radio field intensity information based on a result of a plurality of radio waves respectively emitted from the plurality of antennas having been received by the second wireless communication interface, and, in response to the angle information and the radio field intensity information having satisfied a predetermined condition, transmit 3a request for establishment of wireless communication conforming to the Bluetooth standard to the first wireless communication interface via the second wireless communication interface.

A communication apparatus searches for a device using a first wireless communication, instructs, using the first wireless communication, a device selected from a list based the result of the search to operate in an access point mode, obtains, using the first wireless communication, connection information from the device operating in the access point mode, establishes a second wireless connection with the device based on the obtained connection information.

A communication device including a processor configured to, when executing processor-executable instructions stored in a storage unit, perform determining a first configurable range including setting values stored in the storage unit, acquiring, from an image processing apparatus via a communication unit, a second configurable range including setting values for image processing executable by the image processing apparatus, determining whether the first configurable range is equal to the second configurable range, when determining that the first configurable range is equal to the second configurable range, transmitting an image processing instruction to perform an image processing operation according to the setting values of the first configurable range stored in the storage unit, to the image processing apparatus via the communication unit, and when determining that the first configurable range is different from the second configurable range, restricting transmission of the image processing instruction to the image processing apparatus.

A transmission apparatus includes a scanner. A first control is performed about reading of a plurality of pages of documents by using the scanner to generate image data. A second control is performed about conversion processing of the generated image data. A third control is performed about transmission of processed data on which the conversion processing is performed. The third control includes starting a session while a document is being read based on the first control, and transmitting, to an external apparatus via a network, the processed data on which conversion is already performed. Where an error occurs in the scanner in reading the documents, the third control further includes disconnecting the started session. Where the error is resolved, the third control further includes connecting the session again and transmitting, to the external apparatus via the network, processed data on which the conversion processing is performed.

A non-transitory computer-readable medium stores computer-readable program instructions executable by a processor of a relay device communicable with a terminal management device and one or more terminal devices. The program instructions are configured to, when executed by the processor, cause the relay device to perform unicast communication with each terminal device, thereby obtaining at least one of a device name and a vendor name of each terminal device as determination information, determine, based on the determination information, whether each terminal device is a supported terminal device to be managed by the terminal management device, and perform unicast communication with one or more individual terminal devices each determined to be the supported terminal device, thereby obtaining terminal information from each supported terminal device, the terminal information regarding each supported terminal device being collected by the terminal management device via the relay device.

An information processing apparatus includes a processor configured to provide an operation screen on which a communication destination is set for an external terminal that operates a processing apparatus that performs predetermined processing in advance for each processing content, and set a command destination of the processing content as the communication destination set for the processing content accepted from the external terminal.

A function executing device is configured to send a wireless identifier to a communication device via a first type of wireless communication interface for setting up a wireless connection. The function executing device is configured to determine whether the function executing device is in an error state and, if not, to establish the wireless connection via a second type of wireless communication interface. The function executing device operates in a parent state in the wireless connection. Additionally, print data may be received from the communication device. However, if the function executing device is in an error state the wireless connection is not established via the second type of wireless communication interface.

A communication apparatus is equipped with a direct wireless communication function for executing a direct wireless communication with an external apparatus without a relay apparatus. Executed instructions cause the information processing apparatus to perform operations includes specifying a user who logs into the communication apparatus, and executing a direct wireless communication function. An SSID of a plurality of SSIDs including at least an SSID of a first type corresponding to the user who logs into the communication apparatus and an SSID of a second type being different from the SSID of the first type is able to be used in the direct wireless communication function. In a case that the SSID of the first type is used in the direct wireless communication function, an SSID corresponding to the specified user is used in the executed direct wireless communication function.

A method and a device for controlling image-forming devices, and an electronic terminal using the method are provided in the present disclosure. The method includes acquiring currently-available wireless networks; when a wireless network is provided by an image-forming device, acquiring a first network identifier of the wireless network; when a wireless network is not provided by the image-forming device, connecting to the wireless network and acquiring a first device identifier of the image-forming device connected to the wireless network; adding the first network identifier and the first device identifier acquired to the list of the image-forming devices; according to the list of the image-forming devices, selecting a target image-forming device; and connecting to a wireless network corresponding to the target image-forming device and establishing a communication with the target image-forming device, thereby controlling the target image-forming device to execute an image-forming task.

A communication device including a processor configured to, when executing processor-executable instructions stored in a storage unit, perform determining a first configurable range including setting values stored in the storage unit, acquiring, from an image processing apparatus via a communication unit, a second configurable range including setting values for image processing executable by the image processing apparatus, determining whether the first configurable range is equal to the second configurable range, when determining that the first configurable range is equal to the second configurable range, transmitting an image processing instruction to perform an image processing operation according to the setting values of the first configurable range stored in the storage unit, to the image processing apparatus via the communication unit, and when determining that the first configurable range is different from the second configurable range, restricting transmission of the image processing instruction to the image processing apparatus.
