Is there way how to enforce nmap waiting for replies longer (10 seconds)? I want to scan an embedded device which utilizes some sleep modes and it process packets from wi-fi module with very high delay of several seconds (pings shows delay in range 3 - 8 seconds. If I run nmap using following parameters (which are inspired by zenmap default profile Intense scan with UDP):
nmap -sS -sU -T4 -A -v -oX aaaaaa.xml 192.168.XXX.YYY
it fails at first ping marking the host 192.168.XXX.YYY down. I tried adding recommended -Pn flag but it fails for similar reason one step further - at ARP ping.
Host discovery disabled (-Pn). All addresses will be marked 'up' and scan times will be slower.

Is there way to set timeout when waiting for all replies?
