Active scanning process is a task and there is a certain correct way of handling tasks.
Scanning while the Wi-Fi interface is in the associated state (wln.associationstate= 1- PL_WLN_ASSOCIATED) or running its own ad-hoc network (wln.associationstate= 2- PL_WLN_OWN_NETWORK) will temporarily disrupt communications between the device and the "current" access point.
Active detection of networks is performed only on allowed channels, as determined by the wln.domain property. This is because an active "probe" signal is transmitted during the active scanning.
Active scanning can detect a networks that doesn't broadcast its SSID, but you still need to know this network's name in advance.
