INTRODUCTION
The Renesas RL78/G14 RDK offers a quick and easy way to demonstrate, evaluate and develop embedded applications based on the
RL78/G14 MCU and the GainSpan low-power wireless module and embedded platform software for Wi-Fi networks.
The Wi-Fi module firmware runs an embedded Serial-to-Wi-Fi application that includes a wireless connection and a secure network stack
to provide wireless connection. The module supports both being a client connected to a Wi-Fi infrastructure or a limited Access Point (AP)
for direct connection to PC or Smart phones.
A standalone demo also operates out-of-the-box without any need for a Wi-Fi connection. The LCD display will show Temperature, Light
and orientation of the board.
The various demos are selected at power-up by pressing a combination of the three switches to the left of the LCD display (SWITCH 1,
SWITCH 2 and SWITCH 3) while toggling the RESET switch.

RL78/G14 RDK Quick Start Guide
DEMO #1: DEMO +WEBSERVER DEMO WITH LIMITED AP
By simply powering up the board (or by pressing the RESET button), the board starts in mode where the
temperature, the light intensity and the orientation of the board (expressed in degrees) are measured and
displayed on the LCD.
At the same time, the board operates in “Limited Access Point” mode, where it acts as a limited Access Point
(AP) for direct connection to PC or Smart phones via Wi-Fi.
STEP 1: Make sure DIP Switch #2 is in position ON, then provide power to the RDK board via the USB cable provided
with the board. The Web Server Application is launched. The LCD displays the SSID of the Wireless Network (Limited
AP) generated by the RDK, the IP address of the board, and the URL of a web page.
STEP 2: Using a PC or Smart Phone, connect to the “RDK_xxxxxx” wireless network (where xxxxxx
are the last six digits of the Wi-Fi module MAC address.)
STEP 3: Once connected, open a web browser on your PC or Smart Phone and type in
the URL displayed on the LCD: “192.168.240.1/rdk.html”
This opens the web page that is served by the onboard web server. It displays the
temperature, accelerometer and light sensor data, and also allows ON/OFF control of the
LED wheel on the RDK board. (Note that the X, Y and Z data displayed here are
accelerometer raw data expressed in ft/s2).
GainSpan App for iPhone and Android*
The same Demo can be run using an iPhone (or Android*) native application. Download the GainSpan/Renesas iPhone application from
the Apple iTunes store. Search for “Renesas”. Connect the iPhone Wi-Fi to the RDK SSID displayed on the LCD and then launch the
application downloaded in previous step. The app communicates with the Wi-Fi module and uses mDNS or Service Discovery to find the
device. Select “Renesas 1” to connect to the application. The demo has sensor feedback for light, temperature, and the accelerometer. It
is also possible to turn the LED wheel on and off.
*Android application still under development.

RL78/G14 RDK Quick Start Guide
DEMO #2: PROVISIONING
In this mode, the wireless connection between the webserver onboard the RDK and the client (web browser on PC or Smartphone) is not
direct but it is done over a shared Wi-Fi network. The process involves instructing the RDK to connect to a predefined wireless network.
STEP 1: Keeping SW2 pressed, press and release the RESET button. The LCD will
display “Limited AP:” an SSID and two URLs:
STEP 2: On a PC or Smartphone, connect to the same SSID (ex. “RDK_1ca795”)
displayed in the LCD.
Type in the IP address and URL for the provisioning page (“192.168.240.1/prov.html”)
using a web browser.
This will launch the provisioning page as shown below. Select the “Wireless and Network
Configuration Select Existing Network” to scan for available Access Points in the
vicinity.
STEP 3: Choose a suitable Wi-Fi network from the
list and click on the Select button, making sure you
select the network with the lowest (absolute) Signal
Strength (see red circle):
STEP 4: Complete the setup by entering the wireless password, leaving the other fields at default values. Click on “next”, verify the
information and click “Save and Apply” on the next screen to confirm the selection.
STEP 5: You should see “WebProv Done” message displayed on the LCD screen.
Beware of changes in Wi-Fi network password, because once a board is provisioned, it will keep the data in
its non-volatile memory.

RL78/G14 RDK Quick Start Guide
DEMO #3: WEBSERVER DEMO WITH CLIENT MODE
STEP 1: After provisioning (follow steps 1-5 on page 4), press the RESET button while holding down BOTH SWITCH1 and SWITCH3 and
then release the RESET button (SW1). After the reset, the LCD will display: “Connected to” and the SSID of the Wi-Fi network provisioned
(in this case, the Wi-Fi network is “rea-guest-g”) and an IP address (in this case “192.168.1.50”).
STEP 2: Connect your PC or Smartphone to the same Wi-Fi network, open a browser and type in the IP address followed by “/rdk.html”
and you will be able to monitor the RDK.
You can also use the GainSpan App: You will only need to manually insert the IP Address shown on the LCD display when a “Discovery
has failed!” message appears.

RL78/G14 RDK Quick Start Guide
CLOUD CONNECTIVITY DEMOS
The RL78/G14 RDK comes with two Cloud Connectivity demos provided by Renesas’ partners, Exosite and BugLabs.
These demos turn the RDK into a real-time internet enabled device. Once the board is registered, the device will automatically connect to
the cloud platform and share its peripherals using a standardized API. This enables developers to create applications for the evaluation
board in a wide variety of languages, without needing to download an SDK or physical access to the device.
NOTE: Make sure to follow the “Provisioning” steps (1 thru 5, page 4) before running these demos.
DEMO #4:BUGLABS CLOUD CONNECTIVITY DEMO
STEP 1: After provisioning (follow steps 1-5 on page 4), press the RESET button while holding
down all 3 Switches.
STEP 2: After rebooting, the device will automatically connect and begin producing data. Note the MAC
field on the third line, and keep an eye on the screen for any errors.
STEP 3: You will need to re-connect your PC or
Smartphone to the provisioned wireless access point (steps 1-5 on page 4) with an internet
connection. Navigate to “http://bugcommunity.com/rdknext/”. In the first dropdown box, select
the YRDKRL78G14 board and click "Go!"; Click on the second dropdown box. You should
see the MAC from the LCD screen in the list. Select that entry and click "Go!”
NOTE: if you are using IE10, you might see a long number instead of the MAC address: don’tworry, the long address that you
are seeing in IE is actually your board's Swarm Resource ID. IE's way of parsing data within certain HTML tags is different from
Chrome and Firefox, which is why the address displayed in the
dropdown menu does not get updated to the MAC
address.
STEP 4: Once you hit “Go!” you should now see live data from your Renesas device through the
cloud. You can monitor the data coming from the board (X, Y, Z Acceleration, Temperature, Light level, Potentiometer value, Buttons
status and Sound Level) and Send text to the LCD, turn on and off the LEDs, and send an Audio signal.
NOTE: In order to hear the sound, you need to set JP3 jumper to the 1-2 position.
In order to switch the LEDs on and off, click on the 0 or 1 value below the LEDx
text.
