-band Wi-Fi 4 Cloud

Connectivity Manager

Getting started

Note:

Connect the kit only to a 2.4-GHz Wi-Fi network.

4.5.1

Using Cirrent Wi-Fi onboarding app

The Cirrent cloud solution from Infineon provides an effective Wi-Fi onboarding service through the Cirrent Wi-
Fi onboarding app for any IoT product. The IFW956810 CCM evaluation kit supports onboarding through either
Bluetooth® LE or SoftAP.

Download and install the Cirrent Wi-Fi onboarding app from

Google Play Store for Android

iOS App

Store for iOS on your mobile phone

. Scan the following QR code relevant to your mobile device:

Android

iOS

Type the following command in the serial terminal on the PC.

AT+CONFMODE

You should receive

the “

OK CONFMODE Enabled

”

response from the module.

Open the Cirrent Wi-Fi onboarding app.
You can skip the sign in to perform Wi-Fi onboarding.

From the menu, select

Configuration

and then choose either

BLE

Soft AP

onboarding.

Follow the onscreen instructions and enter the Wi-

Fi router’s SSID and password.

4.5.2

Using AT commands

AT commands provide a simple method of Wi-Fi onboarding in a development environment.

•

Type the following commands in sequence in the terminal application:

AT+CONF SSID=<your router ssid>

AT+CONF Passphrase=<your router passphrase>

Note:

Your local router’s SSID and passphrase are stored securely inside the

IFW56810 CCM module.

While the SSID can be retrieved later (i.e., for debugging purposes), any attempt to retrieve the
passphrase will return an error.

4.6

Connect and interact with the AWS Cloud

Use the MQTT client in the AWS IoT Console to monitor the communication between your evaluation kit and
the AWS Cloud.

Navigate to the AWS IoT Console (

https://console.aws.amazon.com/iot/

In the navigation pane, choose

Test

and then click

MQTT Test Client

Subscribe to a topic

panel, enter

, and then click

Subscribe

Skip Section
