OpenViBE forum

Hello,

I tried to use the OpenVibe Acquisition Server, but I don´t know what number I need to put in the "Sample count per sent block". I read at site that this configuration is about the frequence. If I want use the 256Hz, what is the number that I need put in this blanck?

Thank you soo much for your atenction

In openvibe, the data are sent by chunks (blocks), i.e., samples are not sent one by one from the acquisition server to the designer, but by blocks of several samples (see http://openvibe.inria.fr/acquisition-server/). It is not related to the frequency. The duration (in seconds) of this block depend on how many samples there is in the block and the sampling frequency. But how many samples you put per block does not change the sampling frequency.
So basically you can use the default value (32), that should work fine.
