Hello @AReducer,
I've tested the application, and everything appears to be functioning correctly. Could you please provide more specific details about the problem you're encountering? Any additional information would be helpful to understand and address the issue more effectively.
Regards,
Obj->fops.IO_Init
is called as

then it return SPI_WIFI_ResetModule 's return value rc

rc
is 0
to be successful.

thus, ret
here is 0 to be successful case. But it returns ES_WIFI_STATUS_ERROR
. Shall it return ES_WIFI_STATUS_OK
?

Caution At the return point of ES_WIFI_HardResetModule
https://github.com/STMicroelectronics/STM32CubeL4/blob/692ff21c2b84943aa8e8859e71600b8dc23aaf92/Projects/B-L475E-IOT01A/Applications/WiFi/Common/Src/es_wifi.c#L1530
It requires the return value of
Obj->fops.IO_Init
(i. e. if it's set,SPI_WIFI_Init
) asret >0
. However, when mode passed toSPI_WIFI_Init
isES_WIFI_RESET
, it callsSPI_WIFI_ResetModule
and return its return value. The called reset module function only has two possible of return values, 0 or -1. So, theES_WIFI_HardResetModule
can only return the case ofES_WIFI_STATUS_ERROR
.Describe the set-up
Additional context change it to
ret == 0
may address this issue.
