Hi, lalit-tmt. I cannot find wiznet5500i on Google.

Most importantly, what is an MQTT AWS iot stack? I'm not sure what you are trying to do.

Do you want to run an AWS EC2 instance as an MQTT broker, such as Mosquitto?

Or are you trying to run an AWS IoT instance to create an MQTT client with AWS?

Both are completely different things.

If you are something like AWS EC2 broker + nRF MQTT, take a look at Nordic's IoT SDK.

Hi, @amigo. Is your solution for MQTT over Ethernet using W5100 and nRF52832 open source? I am working on something similar, and it would be really interesting to see how you did it.

Yes im trying to implement Wiznet AVR library to use. I implemented only socket part of the library. DHCP, PING, and other in future. There is an example of my code In link with comment below posted by Sigurd. Now i implementing MQTT library. Next step is to implement SSL/TLS socket based NRF IoT TLS library but it is hardest part and now i have no idea how to do it)))

Thanks, much appreciated! I am working on a solution to use WIznet's Ethernet chips as transport layer with Nordic's MQTT library. I'll let you know if I get TLS working.
