can I set scan interval for scapy?

[korenron]

I have found a simple code that sacn my environment
work good

but I want to set my own time it will start the scan
and also to now on which channels it is running\scanning

so it will run 5 full scan (all channels) , wait x min -- run scan again

what do I need to set in the sniif command?

def handle_packet(pkt):
    if not pkt.haslayer(Dot11):
        return
    if pkt.type == 0 and (pkt.subtype == 4 or pkt.subtype == 0 or pkt.subtype == 2): #subtype used to be 8 (APs) but is now 4 
       (Probe Requests)
        #logging.debug('Probe Recorded with MAC ' + curmac)
        curmac = pkt.addr2
        curmac = curmac.upper() #Assign variable to packet mac and make it uppercase
        SEEN_DEVICES.add(curmac) #Add to set of known devices (sets ignore duplicates so it is not a problem)
        for item in SEEN_DEVICES:
            TS = datetime.now().strftime("%d/%m/%Y %H:%M:%S:%f")
            if item in KNOWN_DEVICES:
                pass
                #item = d[item]
                #print(pkt.show())
            if pkt.dBm_AntSignal > -50 :
                print (TS + ': ' + item + ' MAC TimeStamp : ' + str(pkt.mac_timestamp) + ' with SSID: {pkt.info}'.format(pkt=pkt) + ' subtype is : ' + str(pkt.subtype)  + ' Signal : ' + str(pk$
            #else:
                #print (TS + "  "  + item + ' with SSID: {pkt.info}'.format(pkt=pkt))
        print('_________________')
