I want to know how to solve the communication with associated wifi devices when AP switch to monitoring mode. Because I want to use the monitoring mode without effects the mobile that was associated in that time.
Monitor Mode provides constant channel scanning with attack detection and forensics (packet capture) capabilities. Capture packets regardless of connected network. No association to AP needed (and no authentication). Because it is not connected to a network, you can't process the Wi-Fi frames. If you switch your AP into monitor mode all clients will be dissociated from this AP.
