13. Navigate to the publish_subscribe.c file to update the MQTT_BROKER_ADDRESS macro with the endpoint address copied
from HTTPS tab. Remove the first string before "." in endpoint and replace it with * and copy it to the REGION macro. In
this case, it is *.iot.ap-southeast-1.amazonaws.com.
14. The created Thing, policy, and certificate are used to interact with the AWS IoT.
5.1.3.5 Access Point Credentials
Enter your credentials (SSID and pass phrase key) in the wifi_config_dct.h file. The CLIENT_AP_SSID macro should be
updated with your access point's SSID, the CLIENT_AP_PASSPHRASE macro should be updated with your access point's
pass phrase key and the CLIENT_AP_SECURITY macro should be updated with the security type of your access point. This
is WICED_SECURITY_WPA2_MIXED_PSK if your access point uses WPA2-PSK. If your AP uses a different security, then
choose the correct one defined in enum wiced_security_t from
AWSIOTPubSub_bootloader_Base_WICED/wiced_base-1.0/components/WIFI-
SDK/WICED/WWD/include/wwd_constants.h
5.1.3.6 Build, Program, and Verify
Your Wi-Fi access point must be connected to the internet to verify the example. Build and program the
publish_subscribe_aws example using a similar procedure to the one provided in
CYW943907AEVAL1F EVK.
After it has been programmed, the CYW943907AEVAL1F EVK will try to connect to AWS IoT and subscribe to the specified
topic. After that, if you press switch USER_1, it will turn LED_1 ON and OFF alternately as shown in
this is being done over the cloud. That is, pushing the switch publishes a message to the cloud. The LED turns ON in response
to a notification from the cloud. You can also observe the messages inside the AWS console. In the AWS IoT console window,
go to Monitor > Messages published to see the number of messages exchanged as shown in
