Abstract

To more appropriately acquire information in Generic Attribute Profile (GATT) data, a control method includes acquiring, upon establishment of a second connection between a communication apparatus and an information processing apparatus through Bluetooth® Low Energy, at least a part of information indicating a structure of GATT data included in the communication apparatus until an area in which a predetermined type of information is stored in the GATT data included in the communication apparatus becomes identifiable, and acquiring the predetermined type of information based on at least a part of the information indicating the structure of the GATT data included in the communication apparatus.

First claim

What is claimed is:

1. A control method for an information processing apparatus that communicates with a communication apparatus through Bluetooth® Low Energy, the control method comprising:
acquiring, as a first acquisition, information indicating a structure of Generic Attribute Profile (GATT) data included in the communication apparatus upon establishment of a first connection between the communication apparatus and the information processing apparatus through Bluetooth® Low Energy;
acquiring, as a second acquisition, a predetermined type of information in the GATT data included in the communication apparatus;
acquiring, as a third acquisition, at least a part of the information indicating the structure of the GATT data included in the communication apparatus upon establishment of a second connection between the communication apparatus and the information processing apparatus through Bluetooth® Low Energy until an area in which the predetermined type of information is stored in the GATT data included in the communication apparatus becomes identifiable;
acquiring, as a fourth acquisition, the predetermined type of information based on at least a part of the information indicating the structure of the GATT data included in the communication apparatus; and
acquiring newly, as a fifth acquisition, no information that is not acquired in the third acquisition from the information indicating the structure of the GATT data included in the communication apparatus in a case where the predetermined type of information acquired in the second acquisition matches the predetermined type of information acquired in the fourth acquisition, and acquiring newly, as the fifth acquisition, information that is not acquired in the third acquisition from the information indicating the structure of the GATT data included in the communication apparatus in a case where the predetermined type of information acquired in the second acquisition is different from the predetermined type of information acquired in the fourth acquisition.

2. The control method according to claim 1 ,
wherein in a case where the communication apparatus to be connected with the information processing apparatus in the first connection is identical to the communication apparatus to be connected with the information processing apparatus in the second connection, the predetermined type of information acquired in the second acquisition matches the predetermined type of information acquired in the fourth acquisition, and
wherein in a case where the communication apparatus to be connected with the information processing apparatus in the first connection is different from the communication apparatus to be connected with the information processing apparatus in the second connection, the predetermined type of information acquired in the second acquisition is different from the predetermined type of information acquired in the fourth acquisition.

3. The control method according to claim 1 ,
wherein in a case where predetermined identification information included in the communication apparatus to be connected with the information processing apparatus in the first connection matches the predetermined identification information included in the communication apparatus to be connected with the information processing apparatus in the second connection, the predetermined type of information acquired in the second acquisition matches the predetermined type of information acquired in the fourth acquisition, and
wherein in a case where the predetermined identification information included in the communication apparatus to be connected with the information processing apparatus in the first connection is different from the predetermined identification information included in the communication apparatus to be connected with the information processing apparatus in the second connection, the predetermined type of information acquired in the second acquisition is different from the predetermined type of information acquired in the fourth acquisition.

4. The control method according to claim 1 , wherein the predetermined type of information is a hash value.

5. The control method according to claim 1 ,
wherein the first connection is established without receiving, from a user, an instruction to execute a predetermined function including processing for establishing a connection between the communication apparatus and the information processing apparatus through Bluetooth® Low Energy, and
wherein the second connection is established upon reception of the instruction to execute the predetermined function from the user.

6. The control method according to claim 5 , wherein the predetermined function includes processing for registering information, in a predetermined program configured to execute the predetermined function, about the communication apparatus to be connected with the information processing apparatus in the second connection.

7. The control method according to claim 6 , wherein the predetermined function includes processing for acquiring, via the second connection, connection information for establishing a connection with the communication apparatus to be connected with the information processing apparatus in the second connection through a communication method other than Bluetooth® Low Energy.

8. The control method according to claim 7 , wherein the predetermined function includes processing for transmitting, via the second connection, information for connecting the communication apparatus to be connected with the information processing apparatus in the second connection to an external apparatus located outside of the communication apparatus and outside of the information processing apparatus through a communication method other than Bluetooth® Low Energy.

9. The control method according to claim 8 , wherein the communication method other than Bluetooth® Low Energy is Wireless Fidelity (Wi-Fi®).

10. The control method according to claim 1 , further comprising receiving advertising information,
wherein in a case where the advertising information is received, the first connection between the information processing apparatus and the communication apparatus that has transmitted the received advertising information is established through Bluetooth® Low Energy.

11. The control method according to claim 10 , further comprising executing determination processing for determining, in a case where the advertising information is received, whether the communication apparatus that has transmitted the received advertising information is an apparatus with which the information processing apparatus has previously established a connection through Bluetooth® Low Energy,
wherein in a case where the communication apparatus that has transmitted the received advertising information is determined to be the apparatus with which the information processing apparatus has previously established a connection through Bluetooth® Low Energy, the information indicating the structure of the GATT data included in the communication apparatus that has transmitted the received advertising information is not newly acquired, and
wherein in a case where the communication apparatus that has transmitted the received advertising information is determined not to be the apparatus with which the information processing apparatus has previously established a connection through Bluetooth® Low Energy, the information indicating the structure of the GATT data included in the communication apparatus that has transmitted the received advertising information is newly acquired.

12. The control method according to claim 11 , further comprising executing determination processing for determining whether
