I am using Motive 1.10.1 on a windows box and NatNetSDK 2.10 on a linux box
with the PythonSample
Whenever I send command NAT_REQUEST_FRAMEOFDATA I get the response NAT_UNRECOGNIZED_REQUEST from the server,
The connection works fine as I get the model information when I send NAT_REQUEST_MODELDEF
Has the motive streaming interface changed?
NAT_REQUEST_FRAMEOFDATA results in unrecognised request 100
Re: NAT_REQUEST_FRAMEOFDATA results in unrecognised request
Hi Marek,
The interface has not changed since the release of the python sample.
Can you try running the python client on Windows to see if it works there?

Re: NAT_REQUEST_FRAMEOFDATA results in unrecognised request
Hi Ryan,
It is the same on Windows
i get NAT_UNRECOGNIZED_REQUEST after sending NAT_REQUEST_FRAMEOFDATA
yet the NAT_REQUEST_MODELDEF returns the packet with the info
It occurs on both local loopback and over the network
Just in case my python version (for windows) is 3.5.2.3 and motive 1.10.1.3
Cheers,
Marek

Re: NAT_REQUEST_FRAMEOFDATA results in unrecognised request
After some more testing it seems that the frame_data request is not working with the C library
Looking directly at the packets I see that the correct value is sent:

Also the in Motive log contains the 'model def request' command, but does not show anything when it returns unrecognised request.
Is there a more detailed log?

Re: NAT_REQUEST_FRAMEOFDATA results in unrecognised request
I want to echo Marek's issue on NAT_REQUEST_FRAMEOFDATA. I encountered the same issue when using motive and running the python client on another computer.
It would be great if there can be a solution to this issue. Thank you.
