Problem with the stm32cubeExpansion wifi demo with the x-cube-wifi1

Question asked by kerry liu on Apr 20, 2017
Hello ST community
Now I am working on the wifi module X-NUCLEO-IDW01M1,I found some problem.
Software :STM32CubeExpansion_WIFI1_V3.0.1
IDE: iar arm 7.70.1
From the example project  I found two types one is SPWF01 another is SPWF04, I found the example Binary is the SPW04.
I change the config to SPWF01,but it still not work.
1)en.x-cube-wifi1_firmware (1)\STM32CubeExpansion_WIFI1_V3.0.1\Projects\Multi\Applications\WiFi_VCOM
From the Tera term I found the print message,but when I input 'AT+S.STS',nothing output.
2)en.x-cube-wifi1_firmware (1)\STM32CubeExpansion_WIFI1_V3.0.1\Projects\Multi\Applications\HTTP_Request
From this example it will always run at the wifi init.
 file wifi_module.c line 294 and can not run out this function.It seems to wait for the state.
I only changed one thing in wifi_conf.h
the old one is #define SPWF04,I change to  #define SPWF01
  while(IO_status_flag.WiFi_WIND_State != WiFiHWStarted)
      __NOP(); //nothing to do
//always in this function
Is there anyone can tell me what is wrong ? Thank you very much.
