AT+S.SCAN: perform site survey (scan)

AT+S.SCAN performs an immediate scan for available networks. Infrastructure (AP) and

IBSS(Ad-Hoc) networks are both reported. Network type, Channel, BSSID, SSID, Signal

strength (RSSI), and 802.11 capabilities are all reported. The module supports the

active/passive scan and the filtered/unfiltered scan. Default is active and filtered.

Note:

The automatic scan, performed by the module to connect to the Access Point, is passive by

default. This is done to avoid violating spectral emission. The switch to active scan only

happens when the module finds an AP advertising the country IE. Therefore, the current

scan policy is not compatible with band-steering mode.

Arguments:

<a|p>: Perform an active scan (a) or a passive scan (p)

<r>:

duplicated networks are displayed (unfiltered)
