Quick Start Guide for Wake on Lan
(1) Support list:
.) USB interface: 8188EU, 8188CU, 8192DU, 8192EU.
.) SDIO interface: 8189ES, 8723BS.
(2) Requirements of wakeup via in-band and out-band methods:
.) In-band requirements:
n
SDIO Interface:
ü
SDIO host MUST support remote wakeup feature.
ü
SDIO data1 MUST be wakeup source in the host platform.
ü
The platform MUST keep power to WiFi chip in suspend state.
ü
The platform MSUT work fine
between
suspend and resume.

USB Interface:
ü
USB host MUST support remote wakeup feature.
ü
The platform MUST keep power to WiFi chip in suspend state.
ü
The platform MSUT work fine between suspend and resume.
.) Out-band requirements:
ü
The GPIOof the
PLATFORM
MUST be wakeup source.

ü
The platform MUST keep power to WiFi chip in suspend state.
The platform MSUT work fine between suspend and resume.
The WIFI module MUST have the GPIO
wakeup
pin.
(3) Driver Configuration for Wake on Lan:
.) In-band configuration:
If using
SDIO DATA1 pin
or
USB protocol D+/D- toggle
in-band method
to wakeup the host, driver need to do is only switch
CONFIG_WOWLAN
from
“n”
to
“y”
in Makefile as figure 1.
(figure 1)
2
.) Out-band configuration:
If using out-band method, driver need to do is modify Makefile and config
GPIO. The detail is as following:
n
Makefile Configuration:
Switch
CONFIG_WOWLAN
and
CONFIG_GPIO_WAKEUP
from
“n”
to
“y”
as figure 2.
(figure 2)
n
GPIO Configuration:
Please contact with RTK technical support team.
(4) The wake yo reasib table:
The DUT could be waked up by the WIFI chip with the following reasons:
Reason Value
0x02
0x04
0x08
0x10
0x21
0x22
Description
Receive group key change packet.
Receive disassociate packet.
Receive de-auth. packet.
AP power off, or could not receive
AP’s beacon in a period time
Receive magic packet.
Receive unicast packet.
The unicast packet included IP level.
Note
8723BS support GTK offload.
