INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract 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. ## Claims ### Claim 1 A communication apparatus comprising: 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, wherein, 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. ### Claim 2 (depends on 1) The communication apparatus according to claim 1, wherein the at least one processor is configured to cause the communication apparatus to act as a second determiner that determines whether the power-off instruction is an instruction based on a user operation, wherein, in a case where the first determiner determines that the auto power-on function is set to be enabled and the second determiner determines that the power-off instruction is the instruction based on the user operation, the first communication portion disconnects the connection to the external apparatus, which has been established based on the Bluetooth Low Energy communication scheme, and transmits the advertising information that allows the response based on the Bluetooth Low Energy communication scheme to be received. ### Claim 3 (depends on 2) The communication apparatus according to claim 2, wherein, in a case where the first determiner determines that the auto power-on function is set to be enabled and the second determiner determines that the power-off instruction is not an instruction based on a user operation, the first communication portion avoids disconnecting the connection to the external apparatus, which has been established based on the Bluetooth Low Energy communication scheme. ### Claim 4 (depends on 1) The communication apparatus according to claim 1, wherein the advertising information that allows the response to be received includes advertising information that allows a connection request based on the Bluetooth Low Energy communication scheme to be received. ### Claim 5 (depends on 1) The communication apparatus according to claim 1, further comprising a power supply controller configured to bring the communication apparatus to the powered-off state based on the power-off instruction, wherein, in a case where the first determiner determines that the auto power-on function is set to be disabled, the power supply controller brings the communication apparatus to a first powered-off state being a state that inhibits communications based on the Bluetooth Low Energy communication scheme from being performed by the first communication portion, and wherein, in a case where the first determiner determines that the auto power-on function is set to be enabled, the power supply controller brings the communication apparatus to a second powered-off state being a state that allows the communications based on the Bluetooth Low Energy communication scheme to be performed by the first communication portion. ### Claim 6 (depends on 5) The communication apparatus according to claim 5, wherein, in a case where the first determiner determines that the auto power-on function is set to be disabled, the power supply controller brings the communication apparatus to the first powered-off state, to thereby inhibit the first communication portion from transmitting the advertising information based on the Bluetooth Low Energy communication scheme. ### Claim 7 (depends on 5) The communication apparatus according to claim 5, wherein the first powered-off state includes a state that allows pressing of a power button of the communication apparatus to be detected. ### Claim 8 (depends on 5) The communication apparatus according to claim 5, wherein the second powered-off state includes a state that allows the advertising information to be transmitted via the Bluetooth Low Energy communication scheme. ### Claim 9 (depends on 1) The communication apparatus according to claim 1, wherein the communication apparatus is powered on when receiving predetermined information as the predetermined condition. ### Claim 10 (depends on 2) The communication apparatus according to claim 2, wherein the instruction based on the user operation includes pressing of a power button performed by a user. ### Claim 11 (depends on 1) The communication apparatus according to claim 1, wherein the connection established based on the Bluetooth Low Energy communication scheme includes connection based on Generic Attribute Profile. ### Claim 12 (depends on 1) The communication apparatus according to claim 1, further comprising a second communication portion configured to perform wireless communications with an external apparatus based on a Wi-Fi communication scheme, wherein, in a case where the auto power-on function is set to be enabled and a Wi-Fi communication function is set to be enabled, the second communication portion is allowed to execute the communications based on the Wi-Fi communication scheme even when the communication apparatus is in the powered-off state. ### Claim 13 A communication apparatus comprising: a communication portion configured to perform wireless communications with an external apparatus based on a predetermined communication scheme; and at least one processor configured to cause the communication apparatus to act as a first determiner and a second determiner, wherein the first determiner 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, and the second determiner determines whether a power-off instruction is an instruction based on a user operation, wherein, in a case where the auto power-on function is set to be enabled and the second determiner determines that the power-off instruction is the instruction based on the user operation, the communication portion disconnects, in response to a power-off instruction, connection to the external apparatus, which has been established based on the predetermined communication scheme. ### Claim 14 A control method for a communication apparatus, the control method comprising: performing wireless communications with an external apparatus based on a Bluetooth Low Energy communication scheme; and determining 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, in a case where it is determined that the auto power-on function is set to be enabled, connection to the external apparatus, which has been established based on the Bluetooth Low Energy communication scheme, is disconnected in response to a power-off instruction, and advertising information that allows a response based on the Bluetooth Low Energy communication scheme to be received is transmitted.
