Hi all,
AWS IoT SDK provides us with API functions to work with Thing Shadow.
But at the same time I may work with Shadow via ordinary MQTT and special topics.
While 1st way should be simpler I personally found 2nd more clear and convenient.
Am I loosing some features working with plain MQTT for shadows? Or both ways are equally good for this purpose?

Hello vlad-hid,
We are actively developing AWS featured libraries, and shadow is one of them. Provided libraries may receive better support but I recommend using whatever method works best for your use case.
Here is a link to the shadow library documentation. https://docs.aws.amazon.com/freertos/latest/lib-ref/c-sdk/shadow/index.html. This may paint a clearer picture and help you decide as to what method you prefer.

Thanks Carl-Lundin-AWS, it’s more clear now.
And thanks again for the link - somehow I failed to find this link from https://docs.aws.amazon.com/ when I did my project (even now I don’t see it there - probably it is missed or badly named…). I got very similar one from Google but it was not fully operational and looked a bit strange.

Hello vlad-hid,
I’m sorry to hear that you were lead to a broken link.
Here are some additional sources if you should need them in the future. In this first link you will find the documentation for our other libraries as well.
