Client Disconnect

KD0RC · July 2021

I am trying to gracefully disconnect my TeensyMaestro from the radio when it is a GUI Client. The idea is that it should not leave a connection open, causing SmartSDR to go into MultiFlex mode.

If I send this API command from a different client, it disconnects my TeensyMaestro just fine. If I issue it from within the TeensyMaestro, it has no effect. (C++ code)

fRig.send("client disconnect " + fRig.Client_Handle );

Client_Handle is the handle for the TeensyMaestro.

If I issue a plain client disconnect (i.e. disconnect everything) from my TeensyMaestro, it disconnects SmartSDR, but not itself.

Is there a sequence of commands that allows a client to disconnect itself?

Have you tried calling shutdown on your TCP socket?

That should be all it takes for the radio to forget about your client.

Thanks Mark! I have not tried that. I will give it a go tomorrow. I will need to dig into the Ethernet library for the Teensy board to see what functions are available.

This project is my first foray into any kind of TCP/IP programming, so everything I do is a new adventure!

Thanks Mark, that worked! Now if I forget and start my TeensyMaestro before starting SmartSDR, I can just power it back off and the connection will clear. Before, I had to select Disconnect and then go through the Disconnect screen and power off the TeensyMaestro anyway.

Now that I have this fixed, I will never start up in the wrong order again... 😄
