Hello,
I am trying to develop an application with the X-NUCLEO-IDW04A1 Wi-Fi evaluation board on a STM32F070 microcontroller. I downloaded the expansion package X-CUBE-WIFI1 that provides implementations for STM32L0, L4, F1 and F4 but not on my target NUCLEO.
I tried to adapt the ST package for my MCU and changed some functions and declarations. I mostly modified the declarations within the stm32_spwf_wifi.h header and I can now run an example from the package without the compiler having any issues.
I'm using the HTTP-request example from the expansion package to test my adjustment of the ST package. After some modifications to suit the STM32F070, I am able to build and push my project on my MCU with the following parameters:
- I'm using the UART bus to communicate with the Wi-Fi module (SPWF04SA) (baudrate 115200)
- The jumpers JP10, JP11, JP12, JP13 are in the UART default jumper configuration
- I'm using the USART2 peripheral to communicate with my computer via a serial console
When I run the example project, I get stuck in the wifi_reset() function in the beginning of the program (this function is called during the initialisation of the Wi-Fi module) :
while(IO_status_flag.WiFi_WIND_State != WiFiHWStarted)
{
__NOP(); //nothing to do
}
It seems like the expansion board never let the MCU know that it has restarted. I can tell from the X-NUCLEO-IDW04A1's LEDs' behavior that its reset occurs normally but it never updates its status to the MCU.
I'm not used to the STM32 environment, but I believe that the WiFi_WIND_State variable is updated by the Process_DeQed_Wind_Indication() function which is called during an interruption produced by one of the timer of the board. This function uses a buffer (wifi_instances.event_buff) to read the data sent by the expansion board between two interruptions but it remains empty even after the reset of the Wi-Fi module.
After some research, I found some people dealing with the same issue with other NUCLEOs (stuck in the wifi-reset() function) and manage to resolve it by updating their Wi-Fi module's firmware, I came to think that updating mine could help, do you think that it could resolve my problem?
Why does the buffer remain empty? Please, provide me with any tips. The problem probably comes from my modification of the expansion package, I can submit it if it's necessary.
Regards,
TR
