This quick start guide explains the process of running the Quick-Connect IoT DA16600 (WiFi BLE) Provisioning
demo on an EK-RA6M4. The demo demonstrates provisioning the DA16600 module to a WiFi network using the
BLE interface and reading temperature and humidity data from the HS3001 sensor into the RA6M4
microcontroller.
A smartphone application is used to provision the DA16600 module to an existing WiFi network using the BLE
interface. A web browser is then used to display the temperature and humidity data read from the HS3001
sensor. Instructions for loading the example project are included at the end of the document as a next step after
running the demo.

2. Features
■System power supplied by micro USB cable
■RA6M4 MCU reads measured data from HS3001 temperature and humidity sensor
■BLE connectivity provided by DA16600 allows easy provisioning to WiFi networks
■WiFi connectivity allows the web browser to display raw humidity and temperature values
3. Overview
The DA16600 Module contains both WiFi and Bluetooth LE radios. A typical use case for such a module is to
use the Bluetooth LE interface to quickly and easily join (provision) the WiFi radio to an existing network. This
demonstration uses an app running on a smartphone to provision the DA16600 module to an existing WiFi
network by using the Bluetooth LE interface to select the network and enter the password.
After the DA16600 is provisioned to the network, the RA6M4 Microcontroller reads temperature and humidity
data via the HS3001 sensor and embeds this information into a simple webpage. This data can be displayed by
connecting a PC to the same WiFi network as the DA16600 and then using a web browser to view the webpages
served by the RA6M4 Microcontroller.

6. Preparing the Demo
6.1 Download the Smartphone Application
The DA16600 module is provisioned to a WiFi network using a smartphone application that is available on the
Apple App and Google Play stores. This app can be downloaded using the following QR code links:
6.2 Obtain WiFi Network Details
You will need to know the SSID and password of the WiFi network to which you want to provision the DA16600
module. When you have this information, keep them at hand because they are required in the next section.
6.3 Status Indication
The red, green, and blue LEDs on the EK-RA6M4 evaluation kit board indicate the status of the demo software
as follows:
LED State
Description
Device is booting.
Device is waiting to be provisioned to a WiFi network.

and select the Start DA1600-based
option.
Step 2: Press the Start button to begin
scanning the DA16600 device.
Step 3: Devices discovered during the
scan are listed in the display.
Step 4: When the scan is complete press
the Connect button next to the DA16600-
xxxx device.
Step 5: When connected press the Start
Wi-Fi network scan button to start
searching for a WiFi network to join.
Step 6: The DA16600 starts searching for
available WiFi networks.

Step 7: Select the WiFi network you want
the DA16600 to join.
Step 8: Enter the password for the WiFi
network then press OK.
Step 9: Connect the DA16600 device to
the select WiFi network by pressing the
Connect to xxx button.
Step 10: The DA16600 attempts to
connect to the select network. This might
take up to 1 minute.
Step 11: When connected to the WiFi
network, press Complete to finish the
process.
Step 12: When provisioning is completed,
the red LED on the EK-RA6M4 EK turns
on. It turns green when the DA16600 has
connected to the WiFi network.

7.1 View Sensor Data
Now that the DA16600 Module has been provisioned to a WiFi network, the sensor data can be read using a
web browser as follows:
1. Discover the IP Address of the DA16600. To do this, log in to the WiFi AP that the DA16600 joined and
determine what IP address it has been assigned. The assigned IP address is also output using the serial
debug interface and can be viewed using the Segger J-Link RTT Viewer.
2. Use a web browser to access the sensor data. When the browser has connected to the DA16600, the blue
LED on the EK-RA6M4 turns on.
3. Press the S1 button on the EK-RA6M4 and the value displayed in the Button Push Count field increments.
7.2 Resetting the Demo
When provisioned, the DA16600 stores information about the WiFi network it has joined in non-volatile memory,
allowing it to re-join the network if it is reset or the power is turned off and on. If you want to provision the
DA16600 to a different WiFi network, this information must be erased. This can be achieved using the following
procedure:
1. Press and hold switch SW1 (factory reset) on the DA16600 Pmod for 20 seconds, then release and wait 10
seconds.
2. Reset the EK-RA6M4 board by pressing switch S3. The red led on the EK-RA6M4 should be flashing,
indicating the DA16600 it not provisioned.
8. Starting Development with the Application Project
The source code used to create the demo project is also included in the zip bundle. This project can be imported
into the RA Flexible Software Package (FSP), version 3.4 or higher. The FSP must be downloaded and installed
on a Windows or Linux machine. The e2 studio IDE is included as part of the FSP install. For more information
on the FSP and how it can be downloaded and installed to your local machine, see the resource links in the
following section.
