I am relatively new to GNU Radio. IÂ setÂ up aÂ simple experiment of
file source directly to the usrp sink and monitoring the traffic on the
port using wireshark. The source file simply contains the letters abc.
ran the flowgraph in GRC it did seem to initiate traffic on the ethernet
interface to the USRP but I could not find the string abc inÂ any
I thought that since there is no modulation or any other manipulation of
source data in the flowgraph before the usrp that I would be able to
data string in the ethernet frame. Is there anything the USRP sink block
be doing on theÂ host side that would alter the data before it gets sent
ethernet interface to the USRP?
