We are using mbedtls ssl_client2 and ssl_server2 examples with cert chain of root,intermediate and device.
Please refer earlier conversation as per below link
My own sample rootCA is failing on handshaking with aws.
We have created a new topic as per earlier request.
We have hard-coded root ca ,intermediate(Server) and device(client) certs and keys in certs.c file.
Please let us know if any additional information is required.
