Sending a message give timeout error and can't set different txaddress adnd rxaddress

[jwdsoft]

I'm trying to send a message using this library but I get an error on Channel.SendMessage()
even though I don't have a read command the library is waiting for a response and i'm getting an error
the second problem is how to set the txAddress and rxAddress because I need to specify a particular 29bit address

here is the message I got while sending the message

OK

here is the code I used

`

        MessageFilter FlowControlFilter = new MessageFilter()
        {
            FilterType = Filter.FLOW_CONTROL_FILTER,
            Mask = new byte[] { 0xFF, 0xFF, 0xFF, 0xFF },
            Pattern = new byte[] { 0x00, 0x00, 0x07, 0xE8 },
            FlowControl = new byte[] { 0x00, 0x00, 0x07, 0xE0 }
        };
        if (comboBox1.Text == "")
            return;
        string DllFileName = APIFactory.GetAPIinfo().FirstOrDefault(x => x.Name == comboBox1.Text).Filename;

        using (API API = APIFactory.GetAPI(DllFileName))
        using (Device Device = API.GetDevice())
        using (Channel Channel = Device.GetChannel(Protocol.ISO15765, Baud.ISO15765, ConnectFlag.NONE))
        {
            try
            {
                Channel.StartMsgFilter(FlowControlFilter);
                textBox1.Text += $"Voltage is {Channel.MeasureBatteryVoltage() / 1000}" + Environment.NewLine;
                Channel.SendMessage(new byte[] { 0x01, 0x02, 0x07, 0xE0, 0x01, 0x03 });
                //GetMessageResults Response = Channel.GetMessage();
            }
            catch (Exception ex)
            {
                MessageBox.Show("" + ex);
            }
        }

Thank you for your help

So, the exception message is the description that the driver sends back, or it’s the generic error code description if there is no description from the driver. If you examine the exception object, I believe it will show what the return code was. I would check that because it seems like the driver might not be returning the correct error description.
