TransportLayerCommand sends on MasterID instead on the BroadcastID

[Flo1989]

Hi,

i have some trouble with the TransportLayerCommand (Subcommand GET_SLAVE_ID). When i Send the command in async mode it returns "XCP_ERR_INSUFFICIENT_BUFFER". When i send it in synchron mode it returns XCP_ERR_OK but sends on Master ID. But i want send on the Broadcast ID which is configured in the TXCPTransportLayerCAN struct.

Code: Select all

           
            TXCPResult result;

            msg = new byte[8];
            txmsg = new byte[6];
            txmsg[0] = (byte)'X';
            txmsg[1] = (byte)'C';
            txmsg[2] = (byte)'P';
            txmsg[3] = (byte)0x0; //identify by echo
            XCPApi.ResetQueue(m_XcpSession, TXCPQueue.XCP_CTO_QUEUE);
            result = XCPApi.TransportLayerCommand(m_XcpSession, (byte)TXCPSubCommands.XCP_GET_SLAVE_ID, txmsg); //async mode
            //result = XCPApi.TransportLayerCommand(m_XcpSession, (byte)TXCPSubCommands.XCP_GET_SLAVE_ID, txmsg, (byte)txmsg.Length, msg, (byte)msg.Length); //synchron mode
            libx_Log.Items.Add(result);
            System.Threading.Thread.Sleep(500);

Can anybody tell me how i can send on the Broadcast ID?

Thanks

Hello,

When i Send the command in async mode it returns "XCP_ERR_INSUFFICIENT_BUFFER".

Indeed, this seems to be a bug. For two of three sub commands of TRANSPORT_LAYER_CMD it is mandatory to use the synchron version of the function. GET_SLAVE_ID is the exception, but the API is currently not allowing it.

When i send it in synchron mode it returns XCP_ERR_OK but sends on Master ID

In our test, this is working as expected. We use one of the examples delivered with the API to do the test. In it, the broadcast ID is configured to 0x300, Master ID to 0x200, and Slave ID to 0x100 (using XCPApi.InitializeCanChannel). We just added at the end, a TransportLayderCommand call. See results on the following picture:

We will fix the function TransportLayerCommand to allow using it asynchron, when sending the sub command GET_SLAVE_ID. Thanks for bringing this to our attention.

Hello again,

When i send it in synchron mode it returns XCP_ERR_OK but sends on Master ID

After further tests we were able to get the Master ID too, as you described. This will also be fixed.

Thanks for bringing this to our attention.
