Stm32 micro controller CAN problem + VP230 interface

hi
I have loaded stm can sample on stm32f103C6 and every thing in CAN loopback mode work fine. but when I set CAN in normal mode so as to send bytes from one micro, and receive those bytes by another micro, it didn't worked. I am running this code for sending bytes from first micro board:
CAN_InitTypeDef CAN_InitStructure;
CAN_FilterInitTypeDef CAN_FilterInitStructure;
CanTxMsg TxMessage;
CanRxMsg RxMessage;
u32 i = 0;
u8 TransmitMailbox;

/* CAN register init */
CAN_DeInit();
CAN_StructInit(&CAN_InitStructure);

/* CAN cell init */
CAN_InitStructure.CAN_TTCM=DISABLE;
CAN_InitStructure.CAN_ABOM=DISABLE;
CAN_InitStructure.CAN_AWUM=DISABLE;
CAN_InitStructure.CAN_NART=DISABLE;
CAN_InitStructure.CAN_RFLM=DISABLE;
CAN_InitStructure.CAN_TXFP=DISABLE;
CAN_InitStructure.CAN_Mode=CAN_Mode_Normal;
CAN_InitStructure.CAN_SJW=CAN_SJW_1tq;
CAN_InitStructure.CAN_BS1=CAN_BS1_8tq;
CAN_InitStructure.CAN_BS2=CAN_BS2_7tq;
CAN_InitStructure.CAN_Prescaler=5;
CAN_Init(&CAN_InitStructure);

/* CAN filter init */
CAN_FilterInitStructure.CAN_FilterNumber=0;
CAN_FilterInitStructure.CAN_FilterMode=CAN_FilterMode_IdMask;
CAN_FilterInitStructure.CAN_FilterScale=CAN_FilterScale_32bit;
CAN_FilterInitStructure.CAN_FilterIdHigh=0x0000;
CAN_FilterInitStructure.CAN_FilterIdLow=0x0000;
CAN_FilterInitStructure.CAN_FilterMaskIdHigh=0x0000;
CAN_FilterInitStructure.CAN_FilterMaskIdLow=0x0000;
CAN_FilterInitStructure.CAN_FilterFIFOAssignment=0;
CAN_FilterInitStructure.CAN_FilterActivation=ENABLE;
CAN_FilterInit(&CAN_FilterInitStructure);

/* transmit */
TxMessage.StdId=0x11;
TxMessage.RTR=CAN_RTR_DATA;
TxMessage.IDE=CAN_ID_STD;
TxMessage.DLC=2;
TxMessage.Data[0]=0xCA;
TxMessage.Data[1]=0xFE;

TransmitMailbox=CAN_Transmit(&TxMessage);
i = 0;
while((CAN_TransmitStatus(TransmitMailbox) != CANTXOK) && (i != 0xFF))
{
i++;
}

i = 0;
while((CAN_MessagePending(CAN_FIFO0) < 1) && (i != 0xFF))
{
i++;
}

and for receiving bytes in the second micro controller I am using this code:

/* CAN register init */
CAN_DeInit();
CAN_StructInit(&CAN_InitStructure);

/* CAN cell init */
CAN_InitStructure.CAN_TTCM=DISABLE;
CAN_InitStructure.CAN_ABOM=DISABLE;
CAN_InitStructure.CAN_AWUM=DISABLE;
CAN_InitStructure.CAN_NART=DISABLE;
CAN_InitStructure.CAN_RFLM=DISABLE;
CAN_InitStructure.CAN_TXFP=DISABLE;
CAN_InitStructure.CAN_Mode=CAN_Mode_Normal;
CAN_InitStructure.CAN_SJW=CAN_SJW_1tq;
CAN_InitStructure.CAN_BS1=CAN_BS1_8tq;
CAN_InitStructure.CAN_BS2=CAN_BS2_7tq;
CAN_InitStructure.CAN_Prescaler=5;
CAN_Init(&CAN_InitStructure);

/* CAN filter init */
CAN_FilterInitStructure.CAN_FilterNumber=0;
CAN_FilterInitStructure.CAN_FilterMode=CAN_FilterMode_IdMask;
CAN_FilterInitStructure.CAN_FilterScale=CAN_FilterScale_32bit;
CAN_FilterInitStructure.CAN_FilterIdHigh=0x0000;
CAN_FilterInitStructure.CAN_FilterIdLow=0x0000;
CAN_FilterInitStructure.CAN_FilterMaskIdHigh=0x0000;
CAN_FilterInitStructure.CAN_FilterMaskIdLow=0x0000;
CAN_FilterInitStructure.CAN_FilterFIFOAssignment=0;
CAN_FilterInitStructure.CAN_FilterActivation=ENABLE;
CAN_FilterInit(&CAN_FilterInitStructure);
/* receive */
RxMessage.StdId=0x00;
RxMessage.IDE=CAN_ID_STD;
RxMessage.DLC=0;
RxMessage.Data[0]=0x00;
RxMessage.Data[1]=0x00;
CAN_Receive(CAN_FIFO0, &RxMessage);

if (RxMessage.StdId!=0x11) return FAILED;

if (RxMessage.IDE!=CAN_ID_STD) return FAILED;

if (RxMessage.DLC!=2) return FAILED;

if ((RxMessage.Data[0]<<8|RxMessage.Data[1])!=0xCAFE) return FAILED;

return PASSED; /* Test Passed */

can anyone tell me what is the problem, shall I set some other parameter as well as CAN_mode ?? i am using vp230 for physical interface and signal are ok. and it is running in fast mode(Rs=0) and the lenght of cable is too short, about(10 cm)
thanks in advanced for any help
