Getting ESP32 talking through Ethernet on SPI rather than WiFi for all comms

Many thanks. Really appreciate your help. Great place to start

using Azure SDK for C

Is this the correct repository then? The Azure SDK for Embedded C is at https://github.com/Azure/azure-sdk-for-c
We don't recommend using the code within this repo for ESP32 or other constrained devices.

Has anyone done such scenario where ALL traffic is redirected to Ethernet and how to go about it?

We ethernet samples but, unfortunately, not with ESP.

1. Using Azure RTOS ThreadX: https://github.com/azure-rtos/samples/ (using NXSecure's TLS and TCP/IP stack)
2. Using FreeRTOS : https://github.com/Azure-Samples/iot-middleware-freertos-samples (using mBedTLS for TLS and LwIP for the TCP/IP stack)

In both cases, the NXP RT1060 or Renesas CK-RX64N use Ethernet using the NXSecure layer and drivers.

Similarly, for ESP you would need to use ESP32-IDF in conjunction with W5500 (looks like there is an example here).

It would be important to ensure the integration works with higher layer network stack components such as ESP-TLS and ESP-MQTT. If all that works as expected, you could start from one of our Arduino samples: https://github.com/Azure/azure-sdk-for-c-arduino
