SD Card on the IDW04A1

[damien_lobb]

Hi,

I am using the IDW04A1 WiFi module for a project where I want to transfer potentially large files to a server. Is there a way of accessing the SD slot from my MCU?

I am using the STM32F401RE MCU and currently I use an external SD to save files. If I can access the on board SD card slot that would make things a lot simpler.

Thanks

​Hi,

you several way to transfer files from/to the SD card:

• through the command interface, using filesystem commands (AT+S.FSC/FSP/...)
• through the air by TFTP or HTTP commands

The SD card is also accessible through the on board http(s) server.

Does this answer your question?

Regards,

Elio
