RaspberryPi AWS - IoT cert problems



I am trying to connect from my RaspPi to AWS IoT.
I am getting the info as below.



"Unable to verify the server's certificate. Either it is invalid,
or you didn't set ca_file or ca_path to an appropriate value."



My settings are:


#define AWS_IOT_MQTT_HOST "xxxx.iot.us-west-2.amazonaws.com"
#define AWS_IOT_MQTT_PORT 443
#define AWS_IOT_MQTT_CLIENT_ID "RaspberryPi"
#define AWS_IOT_MY_THING_NAME "RaspberryPi"
#define AWS_IOT_ROOT_CA_FILENAME "AmazonRootCA2.pem"
#define AWS_IOT_CERTIFICATE_FILENAME "xxx-certificate.pem.crt"
#define AWS_IOT_PRIVATE_KEY_FILENAME "xxx-private.pem.key"



I do not know which RootCA I should put and where to find it.
When I create IoT certificates I have two (prv/pub) keys and "a cert for this thing".
Please let me know how to solve it.

AWS link



started to work.
