A Wi-Fi scan operation can be initiated by calling the
m2m_wifi_request_scan API. The scan can be performed on all 2.4GHz
Wi-Fi channels or on a specific requested channel.
The scan response time depends on the scan options which can be set by
calling m2m_wifi_set_scan_options(tstrM2MScanOption*
ptstrM2MScanOption). For instance, if the host MCU
application requests to scan all channels, the scan time is equal to
NoOfChannels (13) *
ptstrM2MScanOption->u8NumOfSlot *
ptstrM2MScanOption->u8SlotTime.
The scan operation is illustrated in the following figure.Figure 5-1. Wi-Fi Scan
