Pretty new to WiFi I have some beginner questions:
I want to build a small system using a STM32 that should connect to a smartphone using WiFi direct to upload/dowload pictures and other sort of documents.
I'm looking for a wifi module that uses SDIO also, as I want to be at full speed, serial to wifi module would be easier to uses but I don't want to be limited by the UART speed.
I was thinking about using a LILY-W1 module from u-blox as it does WiFi direct.
So, using this kind of module, do I have to code a WiFi stack for the STM32 by myself ?
does the LwIP TCP/IP stack is suitable for SDIO WiFi module ? can I do WiFi direct from it ?
