Also, I verified by looking at the LED "A" on USRP N210, which lights almost after 5 seconds. :)
I thought this should be discussed on gnruadio, so added gnuradio list. I want to convert tx_timed_samples.cpp into python. Can I do that? How can I make a "multi_usrp" ? Also, How can I use a block's data instead of buffer ? e.g tx_stream->send(DATA_FROM_SOME_BLOCK_IN_FLOWGRPAH, samps_to_send, md, timeout); Further, what could be the minimum value of "seconds_in_future" ? In my case, When I set it to 0.3 or below I get following Waiting for async burst ACK... fail What does it mean ? Thanks -- Regards, Sam
