Dear Expert.

Thank you for these days of patient solutions.

First, I want to say that you are right. In fact, Bt Code is no problem. The problem bothers me due to the board we design. Now, I rewrite some configurations to replace it, The Bt and PC can communicate successfully.

And Only 16 bytes data transmit still exist,So what should I do next.

Thanks and Regards.

Hi QiuChi,

On PC side, after transmitting the first 8 bytes data, you call a data receive function:

recieve_FrmFlag=Receive(USBCAN2,0,0,ReceiveBuf,50,100);

data length is 50.

Please change it to 0.

Dear QJ Wang,

After I change the data length from 50 to 0, The Bt Side shows no data to load.

Now I suspect that my for loop function in Send Data is not written correctly.

Thanks and Regards

Dear QJ Wang,

My PC Side Code is the following.

/*==============================================================================
* COMMAND Sent Data
*===============================================================================*/
Get_BinaryData( filename );
ulAddress = 0x00010100;
ZeroMemory(&frameinfo,sizeof(CAN_OBJ));
frameinfo.DataLen= 8;
frameinfo.RemoteFlag = 0;
frameinfo.ID = CAN_COMMAND_SEND_DATA;
ulLength = image_size;

//#3, Loop through the data in the code to be downloaded.
for(ulOffset = 0; ulOffset < ulLength; ulOffset += 8)
{
// Build a send data command.
for(ulIdx = 0; ulIdx < 8; ulIdx++)
{
frameinfo.Data[ulIdx] = image[ulOffset + ulIdx];
}

// See if the entire buffer contains valid data to be downloaded.
if((ulOffset + ulIdx) > ulLength)
{
frameinfo.DataLen = ulLength - ulOffset;
// Send the send data command with the remainder of the data to be downloaded.
//Sleep(1);
send_one_FrmFlag=Transmit(USBCAN2,0,0,&frameinfo,1);
//入口参数----m_devtype:设备名;设备索引号；第几路CAN；要发送的数据帧数组首地址；要发送数据帧数组的长度
//返回实际发送的帧数
// canTxstateFlag=ReadCANStatus(USBCAN2,0,0,&vcs);
//VCS :用来存储CAN状态的CAN_STATUS结构指针。
}
else
{
frameinfo.DataLen = 8;
send_one_FrmFlag=Transmit(USBCAN2,0,0,&frameinfo,1);
Sleep(20);
//入口参数----m_devtype:设备名;设备索引号；第几路CAN；要发送的数据帧数组首地址；要发送数据帧数组的长度
do{
recieve_FrmFlag=Receive(USBCAN2,0,0,ReceiveBuf,50,100);
//入口参数----m_devtype:设备名;设备索引号；第几路CAN；用来接收数据帧的数组首指针地址；用来接收的数据帧数组的长度，等待超时100 MS
//返回实际读取的帧数

} while (recieve_FrmFlag < 0);

if (send_one_FrmFlag < 0)
{
ShowInfo("写入失败",2);
}

rcvID = ReceiveBuf[0].ID;
rcvData = ReceiveBuf[0].Data[0];
rcvDataLen = ReceiveBuf[0].DataLen;
if((rcvID != 0x05a6) && (rcvData != 0))
{
printf(" - COMMAND_SEND_DATA failed!\n");
}
}
recieve_FrmFlag=Receive(USBCAN2,0,0,ReceiveBuf,50,10);
//入口参数----m_devtype:设备名;设备索引号；第几路CAN；用来接收数据帧的数组首指针地址；用来接收的数据帧数组的长度，等待超时100 MS
//返回实际读取的帧数
canRxstateFlag=ReadCANStatus(USBCAN2,0,0,&vcs);
rcvID = ReceiveBuf[0].ID;
rcvData = ReceiveBuf[0].Data[0];
rcvDataLen = ReceiveBuf[0].DataLen;
if((rcvID != 0x07F4) && (rcvData != 0))
{
printf(" - COMMAND_SEND_DATA failed!\n");
}
}

Thanks and Regards

Dear QJ Wang,

My PC Code about send data as follows.

// See if the entire buffer contains valid data to be downloaded.
if((ulOffset + ulIdx) > ulLength)
{
frameinfo.DataLen = ulLength - ulOffset;
// Send the send data command with the remainder of the data to be downloaded.
//Sleep(1);
send_one_FrmFlag=Transmit(USBCAN2,0,0,&frameinfo,1);

// canTxstateFlag=ReadCANStatus(USBCAN2,0,0,&vcs);

}
else
{
frameinfo.DataLen = 8;
send_one_FrmFlag=Transmit(USBCAN2,0,0,&frameinfo,1);
Sleep(20);

do{
recieve_FrmFlag=Receive(USBCAN2,0,0,ReceiveBuf,50,100);

} while (recieve_FrmFlag < 0);

if (send_one_FrmFlag < 0)
{
ShowInfo("write fail",2);
}

rcvID = ReceiveBuf[0].ID;
rcvData = ReceiveBuf[0].Data[0];
rcvDataLen = ReceiveBuf[0].DataLen;
if((rcvID != 0x05a6) && (rcvData != 0))
{
printf(" - COMMAND_SEND_DATA failed!\n");
}
}
recieve_FrmFlag=Receive(USBCAN2,0,0,ReceiveBuf,50,10);

canRxstateFlag=ReadCANStatus(USBCAN2,0,0,&vcs);
rcvID = ReceiveBuf[0].ID;
rcvData = ReceiveBuf[0].Data[0];
rcvDataLen = ReceiveBuf[0].DataLen;
if((rcvID != 0x07F4) && (rcvData != 0))
{
printf(" - COMMAND_SEND_DATA failed!\n");
}
}

Thanks and Regards

Hi QiuChi,

I have no idea about the TX and RX functions: Transmit(..) and Receive(...).

1. What are definition of the arguments of those 2 functions: 0, 0, 1, 50, 100
My understanding is that the last argument of Transmit(..) is the length of TX data buffer. I noticed that you use "1" for all the Transmit(..), so I am confused.

2. What is the definition of the return value of those 2 functions: send_one_FrmFlag, and recieve_FrmFlag

send_one_FrmFlag=Transmit(USBCAN2,0,0,&frameinfo,1);
do{
recieve_FrmFlag=Receive(USBCAN2,0,0,ReceiveBuf,50,100);
} while (recieve_FrmFlag < 0);

Dear QJ Wang,

Thank you for your help this time, the problem is solved, mainly hardware and delay issues.

Thanks and Regards
