Hello All ;

I am sorry if it is not the right forum to post ;

In my project I need a wifi connection ;

My question : is how to choose the best wifi module of my application :

we see that ST has a good wifi module

http://www.st.com/content/st_com/en/products/wireless-connectivity/wi-fi/spwf01sa.html

; and we have other option esp8266

but what is the advantage of each ?

Anyone uses both could tell me the advantages of each please ?

Thank you inadvantage

Depends on your application.

With the SPWF01SA you need also an extra cpu.

I prefer the Esp8266, with Arduino ide you have it up and running in 10 minutes.

And also important there's a big community out there who can help you.

Hi,

You can refer to the

http://www.st.com/content/ccc/resource/technical/document/datasheet/ba/8c/b2/64/02/bc/4e/05/DM00102pdf/files/DM00102pdf/jcr:content/translations/en.DM00102pdf

and this

http://www.emcu.it/WiFi/Presentazioni/WiFiMKT19may2pdf

which explain why to use SPWF01S Series.

Maybe this

is interesting for you.

looking at the STM32F103REY6 chip on the SPWF01SA, it has 3 SPI's. Are all 3 of these available to be programmed (I don't see them mentioned in the datasheet) or is it possible to use one of the SPI's MOSI/MISO,SCLK pins and then just use 3 separate GPIO's for the chip select CS pin for my 3 slaves? I need to be able to run 3 SPI slaves, a 20x4 LCD screen and 3 triac relays thru optoisolators. Is my SPI config possible on this chip/wifi module to get what I need out of it plus the wifi features or do I need to run another MCU along side this chip to do all this?
