right. i tried to connect to your aws with your credentials this morning and just now, but i can not connect also. is something changed in your aws account? i can still connect on my own account.

however i just need to get data from shadow, is there anyother way or library to use ?

you can use any library that can connect to aws iot, odelot's in my case.
getting data from the shadows is simply subscribing to the shadow. when a shadow is changed, it will publish its value.

Code: Select all

char endpoint[]    = "a1z2jqar123yvl.iot.us-east-2.amazonaws.com";
char key[]         = "AKIAJAZ6SYYNWEQ7QC2Q";
char secret[]      = "e1ZQncUzE/hgTKHG5o9CUC0UXqnA+iHnJhs0LDvl";
char region[]      = "us-east-2";
const char* topic  = "$aws/things/ESP8266Test/shadow/update";
