not getting data frames using NatNet SDK 2.1

Post by chris123 » Fri Feb 05, 2010 9:41 am

I'm using the sample code PacketClient included with the NatNet SDK 2.1 and streaming data from Arena 1.5.0.0.

I can query data descriptions and ping the server ok, but when I ask for a frame of data or a test request I get
[Client] received 'unrecognized request'
I also do not get any data using the rest of the sample programs with the SDK.
Any ideas?

Thanks,
Chris

Hey Chris,

Tests here show Arena 1.5 and NatNet 2.1 streaming correctly.

I do get 'unrecognized request' if Arena is set to streaming but no data is actively playing in Arena, either from file or "Live".
Is this a possibility?

I think I have arena set up correctly (see screenshot).
I've loaded in some 2d data, some trajectorized data and a skeleton, turned on and off all the streaming options and still don't get any data coming through.

I used wireshark to look for any output and there don't seem to be any UDP packets being spontaneously broadcast.
If I request a packet with NAT_REQUEST_FRAMEOFDATA the packet I get back seems to be malformed (my machine is 129.215.91.222 and arena is on 129.215.90.205) (see screenshot):

Arena is running on Windows 7 pro.

The images in my previous post seem to have disappeared.
Hopefully the following will work:

Hello,

Arena seems to be broadcasting UDP packets again - not completely sure why. Possibly my firewall was blocking them.
I also found that having no skeleton means that nothing gets broadcast.

Thanks,
Chris
