Issue with RTDE inputs

[jzamora]

Hello everyone,
I am having occasional problems in the RTDE communication. I use @osh Java implementation and the issue may be related to this one from @mbush.

I have many output variables configured and 8 input variables, specifically 8 variables of type INT32 (input_int_register_X). Checking the console with CTRL+ALT+F10, I can see the following warning message: WARNING - RTDE Input buffers full.

Any suggestions on how to solve this? Are the number of inputs limited to a maximum size?
Thank you.

Resolved. The problem was that I was updating the inputs at a too high frequency (125Hz, or 8ms). By using a lower frequency (10Hz, or 100ms), like the one in the example code, the problem has disappeared.

It seems to be a problem with buffer overrun.
See the answer to the question here:

RTDE BrokenPipeError on rtde_client.send(data_object) after communication pause

I use RTDE python code to communicate with the URsim simulation tool in the VirtualBox When I send command by command with short pauses - everything goes smoothly But if I make two minute pause between consecutive rtde_client.send(data_object) - communication fails with the rtde.py", line 267, in __sendall self.__sock.sendall(buf) BrokenPipeError: [Errno 32] Broken pipe error. How should I connect to avoid this error?

The bad news: Lowering the frequency may only delay the problem

Ups!
Wrong post. Sorry
