5.1.2 Scan Options

During Wi-Fi scan operation, the WINC sends probe request Wi-Fi frames and waits for the scan wait time to receive probe response frames in the current Wi-Fi channel. After the scan wait time, the WINC switches to the next channel. Increasing the scan wait time increases the possibility to detect more number of access points during scan operation but this leads to more power consumption and overall scan duration. The WINC firmware default scan wait time is optimized to provide the tradeoff between the power consumption and scan accuracy. The WINC firmware provides flexible configuration options to allow the host MCU application to set the scan time. For more details, refer to the m2m_wifi_set_scan_options API.
