[Discuss-gnuradio] Async Messages for Tx Timestamps |

Hi,
I have a packet-based application where it would be useful to know exactly when
each packet has been successfully radiated by the USRP (N200). It seems that
UHD and gr-uhd already provide similar functionality for receiving asynchronous
messages when a burst has been successfully transmitted (EVENT_CODE_BURST_ACK).
However, in my application, I'm transmitting continuously and don't use
end_of_burst tags. Would it be possible for the USRP to post messages to the
event queue when it has transmitted a sample with a generic tag attached? If
not, will I experience an interruption of my signal or any latency if I insert
end_of_burst tags into my continuous stream of samples? Your advice is greatly
appreciated.
Thanks!
Jordan
