According to various embodiments, the electronic device may transfer the scanning result of the discovery module 510 to the data processing module 520 and may store data about the scanning result in a repository module 812. According to various embodiments, the electronic device may transfer data about the scanning result to the publisher module 540 and the trigger module 550.
According to various embodiments, since the operation of the electronic device to scan the external electronic device consumes a large amount of battery power, the electronic device may stop scanning if a desired device is discovered. According to various embodiments, the electronic device may set a time limit for the operation of scanning the external electronic device. According to various embodiments, when an external electronic device that was connectable to the electronic device moves out of connection coverage, if the electronic device continues to scan the external electronic device, battery consumption and resource waste may occur. According to various embodiments, the electronic device may perform a scan on another external electronic device considering a scan constraint situation of Wi-Fi. For example, in the case of Wi-Fi, the foreground app may scan 4 times at 2-minute intervals and may perform multiple scans in a short time. The background app may perform one scan at a 30-minute interval in total. According to various embodiments, the electronic device may scan another external electronic device considering the scan constraint situation of the communication protocol.

For example, when the application is driven, the electronic device may scan external electronic devices in the order of BLE, Wi-Fi, P2P, UPnP, CLOUD, UWB, and BT. According to various embodiments, the electronic device may scan the external electronic device based on whether real-time data collection is supported and the number of external electronic devices supporting a specific communication protocol. According to various embodiments, the electronic device may collect data in real-time in the case of Wi-Fi and, when the number of external electronic devices supporting Wi-Fi is smaller than the number of external electronic devices supporting BLE, first scan the external electronic devices supporting BLE. According to various embodiments, the electronic device may collect data in real-time in the case of Wi-Fi and may scan the external electronic device supporting BT first if data cannot be collected in real time in the case of BT.
According to various embodiments, the electronic device may determine a communication protocol to scan based on its own location information and location information about the external electronic device. According to various embodiments, the electronic device may identify (or determine) its location information based on the information collected through Wi-Fi and base station location information, compare current location information about the electronic device with location information about the external electronic device registered in the application, and if the location of the external electronic device and the current location of the electronic device meet a preset condition (e.g., within a radius of 100 meters), scan the external electronic device. According to various embodiments, if the location of the external electronic device and the current location of the electronic device do not meet the preset condition (e.g., within a radius of 100 meters), the electronic device may receive only cloud events. According to various embodiments, when the external electronic device is connected to the same wireless network, the electronic device may determine that the preset condition (e.g., within a radius of 100 meters) is met and scan the external electronic device.
According to various embodiments, the electronic device may identify communication protocols supported per device type registered in the application (or account) and may scan the communication protocols supported by the external electronic device based on the communication protocols supported per device type. According to various embodiments, in the case of an external electronic device having a Nearby attribute, such as a SmartTag, initial scanning is important. Thus, the electronic device may add three more seconds to the BLE scanning time.
