Ping statistics for 192.168.0.66:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 14ms, Maximum = 81ms, Average = 34ms
For each ping packet sent, the DA16200/600 will wake up and print a message on the serial terminal
and then return to sleep mode:
Wakeup source is 0x82
>>> TIM STATUS: 0x00000001
>>> TIM : UC
>>> Start DPM Power-Down !!!

Wakeup source is 0x82

How to Add an ARP Record
If the DA16200/600 is in DPM sleep mode and there are multiple network interfaces enabled on the
laptop, an ARP entry must be added for the specific interface so that the laptop knows how to find
the DA16200/600.
This section describes how to add a DHCP assigned IP address to the ARP table and change that IP
address from a dynamic to a static IP address.
Since retransmission logic is not included in the higher protocol (TCP / UDP), an additional ARP
record is required for ping tests between the laptop and the DA16200/600 which is operating in DPM
sleep mode.
1. Use the
arp -s
command to manually add an ARP record to the ARP cache and then use the
arp -a
command to view the ARP table for the network interface.
