Hi,

 

I have an issue.I am using netduino1, Quectel M10 and Quectel L10. When I try to change ports from GPS to GSM ans recieve some data a i got error "A first chance exception of type 'System.ArgumentException' occurred in Microsoft.SPOT.Hardware.SerialPort.dll".

 

Here is my code.

 serial2.DataReceived -= new SerialDataReceivedEventHandler(serial_DataReceived2);

            Thread.Sleep(4000);

            serial2.Close();

            Thread.Sleep(3000);

            serial.Open();

            Thread.Sleep(1000);

            

            serial.DataReceived += new SerialDataReceivedEventHandler(serial_DataReceived);

            Thread.Sleep(3000);

            settings = null;

            while (settings == null)

            {

                initializationPost();

            }

 

I suppose that problem is when I try to remove hadnler and than close the port, port is still recieving data and it throws an exception.

Could you please help me how to solve this?

Hi holdonson,

Can you share a bit more of your code (or make a simple 10-line sample app which reproduces the issue) so we can help dig into it a bit more with you?
