Please configure the ssid and password that need to be connected to WiFi in advance,in main.c.

#define ROUTER_SSID "your ssid"
#define ROUTER_PWD "your password"

According to the AWS IoT Development Guide, the developer shall obtain:

xxx.cert.pem

xxx.private.key

AmazonRootCA1.pem

xxx-ats.iot.us-east-2.amazonaws.com(endpoint)

Download the above certificate to replace the certificate and host in aws_test_cert.h
