DA16200 DA16600 FreeRTOS Getting Started Guide
For each ping packet sent, the DA16200/DA16600 will wake up and print a message on the serial
terminal and then return to the low power mode:
Wakeup source is 0x82
>>> TIM STATUS: 0x00000001
>>> TIM : UC
>>> Start DPM Power-Down !!!
rwnx_send_set_ps_mode PS TIME (us) 139351

How to Add ARP Record

This section describes how to add a DHCP assigned IP address to the ARP table and change that IP
address f rom a dynamic to a static IP address.
If the DA16200/DA16600 is in DPM low power mode and there are multiple network interf aces
enabled on the laptop, an ARP entry must be added f or the specif ic interf ace so that the laptop
knows how to f ind the DA16200/DA16600.
Since retransmission logic is not included in the hig her protocol (TCP / UDP), an additional ARP
record is required f or ping tests between the laptop and the DA16200/DA16600 which is operating in
DPM low power 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 f or the network interf ace.
C:\user\testuser>arp -s 192.168.0.66 d4-3d-39-10-a2-48
C:\user\testuser>arp -a
Interface: 192.168.0.105 --- 0x12
Internet Address
192.168.0.1
192.168.0.66
192.168.0.255
224.0.0.2
224.0.0.22
224.0.0.251
239.255.255.250
255.255.255.255
The DA16200's IP address 192.168.0.66 is now added to the ARP table as a dynamic type.
NOTE
When setting up the ARP cache to static with the command arp -s on higher versions of Windows, an
error like Failed to add ARP entry, Access is denied. will be occurred. Renesas recommends
using command netsh to change the network settings.
