How do I specify to connect to a particular radio on my Network?

The discover broadcast packets sent out from the radios contain s/n and IP. Use that to listen for the radio you want (s/n) then connect to that IP.

Hi Brad,

Here is a link to a C# ,net demo program that uses FlexLib. I did this as an exercise to learn C# and to understand FlexLib. I don't pretend that this is great code, but it does work.

I use the Visual Studio 2019 IDE.

The comments with the "**" in them are my comments about grabbing multiple radios.

private void API_RadioAdded(Radio radio)
    {
      _thisRadio = radio;  // ** This could be an array, grabbing each radio that it finds.
                           //    You would need a radio counter to set the index of the array.

      SerNum = radio.Serial;  // ** Also could be an array.  
                              //    It would use the same radio counter (above) as the index.

      // The properties, such as Nickname and Callsign, can't be read
      // successfully until you've received a PropertyChanged event
      // for that property... this is done after connect.
      //
      //radio.PropertyChanged += radio_PropertyChanged;
      radio.PropertyChanged += new PropertyChangedEventHandler(radio_PropertyChanged);
      radio.SliceAdded += new Radio.SliceAddedEventHandler(radio_SliceAdded);
      radio.SliceRemoved += new Radio.SliceRemovedEventHandler(radio_SliceRemoved);
      radio.PanadapterAdded += new Radio.PanadapterAddedEventHandler(radio_PanAdded);
      radio.SlicePanReferenceChange += new Radio.SlicePanReferenceChangeEventHandler(radio_PanRefChg);
      radio.VoltsDataReady += new Radio.MeterDataReadyEventHandler(_thisRadio_VoltsDataReady);
      radio.PATempDataReady += new Radio.MeterDataReadyEventHandler(_thisRadio_PATempDataReady);
      radio.GUIClientAdded += new Radio.GUIClientAddedEventHandler(_thisRadio_GUIClientAdded);
      radio.GUIClientUpdated += new Radio.GUIClientUpdatedEventHandler(_thisRadio_GUIClientUpdated);
      radio.GUIClientRemoved += new Radio.GUIClientRemovedEventHandler(_thisRadio_GUIClientRemoved);
      radio.MessageReceived += new Radio.MessageReceivedEventHandler(_thisRadio_MessageReceived);

      radio.Connect();  // ** Add conditional logic here to only connect to the desired radio 
                        //    based on radio.Serial or radio.IP.  Could also have a chooser screen here.

      form1.txtDebug.Text += "Status: " + radio.Status + NL;
      form1.txtDebug.Text += _thisRadio.GuiClientHosts + NL;

      ParseConfig();
    }

I hope that this helps. As I have never actually had two Flex 6000 series radios in the same place at the same time, I have never actually enumerated multiple rigs, but I think this is a step in the right direction.

If you are not using FlexLib, I have some C++ examples that I think would translate to C# pretty easily.

Be sure to post back with any progress you make and/or help that you need.

Hi Brad, if there are multiple radios on the LAN, I think each one will cause an API_RadioAdded event. If you don't check for the desired serial number or IP address before doing the radio.Connect(), it will connect to the first radio it finds, then will attempt to connect to the next one it finds. I don't know what happens, but I doubt that it would be the desired result.

So what you could do is something like this. Put the radio.Connect(); statement in the following if statement. You would obviously use the proper serial number.

if(radio.Serial == "720-1014-6400-1234")
{
  radio.Connect();
}

I can't test this, but give it a try and let us know if it works. Can you confirm that you are using C# with FlexLib?
