Caution
At the return point of ES_WIFI_HardResetModule

return (ret > 0) ? ES_WIFI_STATUS_OK : ES_WIFI_STATUS_ERROR; |
It requires the return value of Obj->fops.IO_Init (i. e. if it's set, SPI_WIFI_Init) as ret >0. However, when mode passed to SPI_WIFI_Init is ES_WIFI_RESET, it calls SPI_WIFI_ResetModule and return its return value. The called reset module function only has two possible of return values, 0 or -1. So, the ES_WIFI_HardResetModule can only return the case of ES_WIFI_STATUS_ERROR.
ES_WIFI_Status_t ES_WIFI_HardResetModule(ES_WIFIObject_t *Obj)
{
int ret = 0;
LOCK_WIFI();
if (Obj->fops.IO_Init != NULL)
{
ret = Obj->fops.IO_Init(ES_WIFI_RESET); // SPI_WIFI_Init
}
UNLOCK_WIFI();
return (ret > 0) ? ES_WIFI_STATUS_OK : ES_WIFI_STATUS_ERROR;

Additional context
change it to ret == 0 may address this issue.
