Question
Implement AWS stack to STM32F4
Dear ST experts,
I have an STM32F4 board and I plan to connect it to the AWS IoT cloud via a BG96 cellular module. I have found a very similar sample of STSW-STWINCELL and I am trying to transplant the code from STM32L4+ to my STM32F405 MCU.
However, I just found that AWS and the cellular stack requires massive RAM space (the STM32cubeIDE build analyzer indicates that the STSW-STWINCELL project requires 240k RAM even after I disabled the sensors). And the RAM on STM32F405 seems insufficient (128+64k).
Just wonder if the AWS and cellular stack do consume that much RAM? Is the external SRAM the common solution? Is there any other way?
Thank you,
Kai
