Much thanks to Manuel and Gilles for helping me get this far!
I'm trying to connect to endpoint hosted by Google for IoT devices. The handshake appears to progress through certificate verification and key exchange, encrypts a payload and then times out waiting for 5 expected bytes. I've attached the last part of the mbedTLS output generated with DEBUG_LEVEL 5 (the entrie thing is too big to include here). I'm sure the problem is either my code, network configuration, or somewhere else on my end. Can anyone give me a clue as to what might be wrong?
The starting point for attempting the connection is https_client_tls_xchg(), found in the attached snippet from the example httpsclient.c file as I've modified it.
FWIW, I'm using mbedTLS 2.13.1 running on an MIMXRT1062DVJ6A with MCUXpresso SDK 2.6.2. My HTTPS client is based on NXPs example project lwip_httpscli_mbedtls_freertos.
