When power supply is started by, for example, powering on the communication apparatus 151, the short-range wireless communication unit 157 performs initialization processing and transitions to an advertising state. When transitioning to the advertising state, the short-range wireless communication unit 157 periodically broadcasts advertisement information to the periphery at a period corresponding to the advertisement interval. The short-range wireless communication unit 157 may transition to the advertising state and start transmission of advertisement information when, for example, a predetermined operation for enabling the BLE function is performed. Advertisement information is a signal including basic header information (identification information used to identify an apparatus that transmits the advertisement information), and includes a header 401 and a payload 402. The information processing apparatus 101 receives the advertisement information, thereby recognizing the presence of the communication apparatus 151. Furthermore, based on the information of the communication apparatus 151 obtained by the advertisement information, the information processing apparatus 101 transmits a BLE connection request to the communication apparatus 151, and can therefore be BLE-connected to the communication apparatus 151. The header 401 is an area where the PDU (Protocol Data Unit) type of advertisement information, the information of the size of the payload 402, and the like are stored. The payload 402 stores information such as a device name 403 serving as identification information, mounted profile information, connection information 404 used to BLE-connect the communication apparatus 151, and transmission power (Tx Power) 405 of the advertisement information. Note that identification information 406 of the communication apparatus 151 may be included in the advertisement information. The identification information 406 of the communication apparatus 151 includes, for example, the MAC address of the communication apparatus 151. The identification information 406 of the communication apparatus 151 may include the service information of the communication apparatus 151, the S SID of the access point in the communication apparatus 151, a password, or the like.
