Hi Jerdung,
Thanks for the info.
I have tried the configurations which you have provided, with this I am able to establish a TCP connection with mosquito MQTT server.
But when I tried to establish a TCP connection with my AWS cloud its still trowing same error.I have downloaded the root certificate from aws (https://docs.aws.amazon.com/iot/latest/developerguide/server-authentication.html#server-authentication-certs) I am using RSA 2048 bit key: Amazon Root CA 1.Is there anything I am doing wrong here.
I hope to establish the TCP connection with AWS this root certificate is enough.
Are there any documents which explains the procedure to establish the communication between sierra HL7650 and AWS cloud.
