Apply azure-sdk-for-c for smaller ROM size #8

Closed cyliangtw closed 3 years ago

cyliangtw commented 3 years ago

Current ROM size of mbed-os-example-for-azure seems too big for normal MCU platforms. According to my evaluation based on the same NUMAKER_IOT_M487 platform:

We forked & ported mbed-os-example-for-azure on NUMKAER_IOT_M487 in this repo , it could work but ROM size is too big. So, I cross check with azure-iot-preview based on azure-sdk-for-c, this M487 azure-iot-preview repo is ROM size as small as 131 KB. I used the same toolchain to build these 2 examples for Azure connection and the key factor is azure azure-iot-sdk-c v.s azure-sdk-for-c.

So, is there any plan to apply azure-sdk-for-c to fulfill memory footprint of MCU level ?
