Re: [Discuss-gnuradio] Why am I dropping data over the UDP network?

[Ward, Marcus D.]

Alan,

 

I also agree with that, which is why I think it’s probably the reason why I might be losing packets.

 

Right now, I’m experimenting with TCP since during my readings I’ve read that it ensures delivery of all packets and also checks for errors. The current problem with TCP is that I’m getting a socket error: (socket.error:[Errno 111] connection refused) no matter how many ports I open or change it to.

It is my understanding that the UDP protocol does not quarentee delivery to the destination.  That  is, it has no recovery mechanism for undelivered packets.

I'm talking about the UDP traffic between the host and the N2xx device.

Marcus,

What OS are you using? I had the same issue (UDP not getting through on
receive side) with Fedora 20, even with Firewall "supposedly" turned off
(i.e. Trusted Zone selected). Manually adding the port exemption (I believe
I used port 65000) let the UDP through and it worked.
