1 INTRODUCTION

QK-W015 series remote controller is a versatile device which can be attached to many of

electronic devices in homes, offices, plants, or wherever you need. Operators can control any

remote equipments, heater, lights, machines, or power sockets from anywhere in the world

through internet. QK-W015 support three relay outs and 433MHz RF transmitter. RF power

sockets within 50 meters of QK-W015 can be controlled by mobile operators.

2 SETUP

2.1 Power up

QK-W015 remote controller need to be powered by 12VDC voltage. Connect a 12 volt DC

power supply to the power socket, switch on the power supply. The blue LED should light

up and then flashing slowly. After about 10 seconds, the Red LED will light up indication

system finishes initialization.

2.2 Access QK-W015

After QK-W015 finish initialization, operator should be able to scan SSID on the mobile

terminals and find a SSID called ‘WiFi168’. Access WLAN of the mobile terminal and

connect with the ‘WiFi168’. The default password is ‘88888888’. Blue LED will keep light

up once the ‘WiFi168’ is connected by the operators mobile terminal. If ‘WiFi168’ cannot



V1.1

be found, please go to ‘RESET’ section of this application note following the steps to reset

the module.

Figure 3 Connect to QK-W015

3 AD-HOC MODE

The IEEE 802.11 has two basic modes of operation: Ad-hoc mode and infrastructure

mode(also called station mode). In ad hoc mode, mobile terminals transmit directly peer-to-

peer. While In infrastructure mode, mobile terminals communicate through an access point(AP)

that serves as a bridge to other networks (such as Internet or LAN). QK-W015 WiFi controller

can support in both Ad-hoc and Station mode.

Setting QK-W015 works in Ad-hoc mode is quite straightforward. Once the mobile terminal

connected to WiFi168 network, QK-W015 then works in Ad-hoc automatically.



V1.1

Figure 4 Working in Ad-hoc mode

Operator can use the following link to download the latest version of Android App to work with

QK-W015.

3.1 Connect With Mobile phones

Once the ‘WiFi168’ is connected, operators can control these electronics devices in

‘Main control panel’ which have connected on relays and RF main sockets. The

indicator icons (the light bulb next to ‘Off’ button) can demonstrator each relay.

Due to one way communication between QK-W015 and 433MHz RF main sockets,

the status of the RF main sockets cannot be check and indicated.

3.2 Rename the port

Operators can rename the three relay outputs and three RF main sockets as meaningful names

through settings on App.

Figure 7 Rename the port

4 STATION (INFRASTRUCTURE) MODE

To control QK-W015 remotely, it should be set working in station mode, operator need perform

the following procedure to finish the setting.

1,Press and hold the ‘Reset’ button, then power up QK-W015. The blue LED will light up for few

seconds, then the red LED turns on. Keep the red LED turns on for 3 seconds, release

‘Reset ’button.

These icons indicate the

status of the relays.



V1.1

2, Wait for 60 seconds, red LED turns off and then turns on again. During this period, blue LED

blinking every second interval.

3, Operator can now use the mobile terminal search and connect ‘WiFi168’.

4, Once this Ad-hoc connection has been setup, operator can start the following setting through

APP.

SSID name ---- Input the SSID name(or called AP name) which QK-W015 will access to.

Password --- Input the password for accessing AP. Quark-elec notices for some old type

Access Point, they maybe have connection problem with QK-W015 if the AP security type

set as ‘WEP’. So, if operator has the access problem, please change the security type to

‘WPA’ or ‘WPA2’, avoiding ‘WEP’ on the wireless router.

IP address --- Dynamic IP address will be assigned by QK-W015 if operator don’t set a

static IP address on APP.

5, Re-power up QK-W015 to apply the remote control function.

4.1 Station mode setting through APP

Operator should make sure QK-W015 has connected with the mobile terminal in ad-hoc

mode before the following setting. Run the APP, click ‘Station mode setting’, input SSID of

the AP and then ‘Save’. The red LED will turn off. Keep waiting until the response

message received from QK-W015. Then the same way applies for setting the password. It

is recommended that operator don’t set static IP address to QK-W015 if static IP address

has to be used.



V1.1

Figure 8 Station mode setting

4.2 Switching to station mode

Once the above setting finished, operator can click ‘Switch to station mode’ to set QK-

W015 working in station mode.

After click ‘Switch to station mode’, the red LED light will turn off indicating system is busy.

Waiting about 90 seconds, the blue LED will turns off. Another 30 seconds, the red LED

light turn on firstly and then the blue LED. If the SSID or password is not correct, then the

blue LED will keep blink. In this case, operator should reset the module and repeat the

setting procedure again.

Once QK-W015 has successfully connected with the AP in station mode, operator should

re-power up QK-W015 to get the full function applied (don’t press the reset button during

the re-power process).



V1.1

Figure 9 Switch to station mode

4.3 Reset

Operator can always reset QK-W015 if the setting is incorrect or would like to switch the working

mode. Following below steps to reset QK-W015 to the factory settings:

1, Power off QK-W015.

2, Press and hold the ‘Reset’ button, then power up QK-W015. Blue LED will light up for few

seconds, then the red LED turns on. Keep the red LED turns on for 3 seconds, release

‘Reset ’button.

3, Wait for 60 seconds, the red LED turns off and then turns on again. During this period, the

blue LED is blinking every second.

4, Operator can now available to connect to ‘WiFi168’.

5 PARING WITH RF POWER SOCKETS

QK-W015 has a build-in 433Mhz RF transmitter module. It can pair with up to four RF power

sockets. So the operators are able to turn ON/OFF the electrical devices by switching the

power sockets.

The power sockets have been paired and ready to use if they come with QK-W015. However

the operator can always pair or release the pairing by following steps:

Insert the RF power socket into a powered mains wall socket.

The LED light on the socket should flash at 1 second intervals indicating it’s ready to

pair with the QK-W015. If the lights doesn’t flash, press and hold the ON/OFF button for

5 seconds to clear the memory indicated by the quickly flashing LED.

Open WiFi Remote control panel in App, press the corresponding RF switch ‘ON’

button. The paring command will be sending out through RF signals.



V1.1

Figure 10 RF Switch ON buttons

Once the power socket received the paring command, The LED light on the socket will

flash briefly more quickly and then flash at 1 second intervals. This RF main socket

should have been successfully paired now.

Repeat above process for each different RF main sockets.

Simply plug-in the appliance which you want to operate remotely into the socket, press the

corresponding ON button on App that is paired to the socket. The appliance will turn on.

6 APP(ANDROID VERSION)

The latest version of Android APP can be downloading with the following link:


Once the mobile phone has connected with QK-W015, the operator can control

these electronics devices which connected on relays and RF main sockets. And the

operator can check the relays status by click ‘Check relays status’.

7 HARDWARE

7.1 Connections

General view of the module is show as below and details of each connection are described on it.

QK-W015 use 12VDC 1.0Amp power. The outside and inner diameter of the plug is 5.5mm and

2.1mm.

7.2 RF main sockets

Customer can select USA, European or UK type RF main sockets. Quark-elec standard RF

main sockets support 2000 Watts power rating.

Although QK-W015 have running specific algorithm to increase the RF transmission reliability,

Quark-elec cannot guarantee 100% of proper action rate of RF main sockets. QK-W015 RF

signal could be affect by other nearby RF devices such as bell ring, car key, cordless phone,

mobile phone, RF alarm system. The following is a real test result taken in a house

environment in the UK.
