Hello everyone,I am trying to implement some relaying schemes in gnuradio which requirefast response from the relay. I only know how to use flow graphs at the moment so I made my code with flowgraphs and the delay from receiving a packet until I retransmit it is about 10ms. I'm using USRP1 and the sampling rate is 2MSPS and I use the autotransmit capability of USRP. First of all I'm trying to understand where the delay comes from.
Hi,I'm not entirely sure, but I think there is a sleep in the (FlexRF) daughter- board drivers... Try grepping "usleep".
