A control unit is configured to perform second control for stopping operation in a predetermined mode based on a second time shorter than a first time, the second time having elapsed with connection setting not made since the operation in the predetermined mode by a communication apparatus was started in a case where the communication apparatus is operating in the predetermined mode and the predetermined processing is completed.

Communication apparatus configured to start and stop operation in predetermined mode for receiving setting information from information processing apparatus

A communication apparatus includes a control unit configured to perform, in a case where the communication apparatus is operating in a connection setting mode and a predetermined process is completed, control to stop operation in the connection setting mode based on passage of a second time longer than a first time without performance of connection setting from a start of an operation of the communication apparatus in the connection setting mode.

Communication apparatus and method for controlling the same

Provided is a communication apparatus including: a first communication portion configured to perform wireless communications with an external apparatus based on a Bluetooth Low Energy communication scheme; and a first determiner configured to determine whether an auto power-on function of powering on the communication apparatus under a predetermined condition even when the communication apparatus is in a powered-off state is set to be enabled, wherein, when the first determiner determines that the auto power-on function is set to be enabled, the first communication portion disconnects connection to the external apparatus, which has been established based on the Bluetooth Low Energy communication scheme, in response to a power-off instruction, and transmits advertising information that allows a response based on the Bluetooth Low Energy communication scheme to be received.

Communication apparatus and control method therefor

A communication apparatus includes a first communication portion configured to perform wireless communications with an external apparatus based on a Bluetooth Low Energy communication scheme, and at least one processor configured to cause the communication apparatus to act as a first determiner that determines whether an auto power-on function of powering on the communication apparatus under a predetermined condition even when the communication apparatus is in a powered-off state is set to be enabled. In a case where the first determiner determines that the auto power-on function is set to be enabled, the first communication portion disconnects, in response to a power-off instruction, connection to the external apparatus, which has been established based on the Bluetooth Low Energy communication scheme, and transmits advertising information that allows a response based on the Bluetooth Low Energy communication scheme to be received.

A communication apparatus has a communication function that can concurrently perform first communication in which communication with a partner apparatus is performed via another apparatus that decides a wireless channel to be used in the wireless communication and second communication in which communication with the partner apparatus is performed not via another apparatus by the communication apparatus deciding the wireless channel. In a state in which the first communication and the second communication are concurrently performed, if a connection for the first communication is to be established while a connection for the second communication is established, a second wireless channel used for the second communication is set so as to match the second wireless channel with a first wireless channel to be used when the connection for the first communication is established.

Communication apparatus, control method, and computer-readable storage medium

There is provided an ink jet printing apparatus that does not give poor usability to users and a method for controlling the same. To achieve this, in recovery processing performed multiple times to recover an ejection state, in a case where a printing instruction is inputted, the recovery processing is suspended in an amount smaller than an amount required for recovery, depending on an amount of ink in an ink tank.

Ink jet printing apparatus and method for controlling the same

A printing apparatus includes a main tank for containing ink; a sub tank for containing ink supplied from the main tank and containing ink to be supplied to a print head; a detection unit configured to detect an ink amount in the sub tank; and a filling unit configured to perform ink filling operation that fills the sub tank with ink from the main tank by driving a driving unit, in a case where the detection unit detects the ink amount in the sub tank that is less than a first predetermined amount, wherein in a case where the ink amount in the main tank is less than a second predetermined amount, the filling unit drives the driving unit at smaller drive amount than that in a case where the ink amount in the main tank is greater than the second predetermined amount.
