ESP12E WIFI MODULE TO STM32F401VDT

Question asked by amarr.mandha on Feb 4, 2017

Hi sir,

My name is amar. Presently am working on ESP12E module and trying to communicate with STM through HSPI protocol(GPIPO12=HSPI_MISO, GPIO13=HSPI_MOSI, GPIO14=HSPI_CLK, GPIO15=HSPI_CS).

Am just sending AT command but module is not responding to that command..
But my side CLK,MOSI and CS are fine(i checked all in oscilloscope)..

I googled about ESP12E module but no one explianing exactly about module and finally confused me.

I have major doubt is How to jump into HSPI Mode??????????

I thought ESP12E 3 SPI Modes from that HSPI is one.

some where told that ESP12E will not give response for AT commands through SPI mode

for that purpose I shifted to HSPI

 

Please help me sir

Thank you.
