Hi all,
I think I may have identified the problem. See what you think.
I added a bit more info output to the tx_timed_loop.cpp test program (see
attached) and made note of the time a packet is scheduled to go out versus the
time the send loop completes.
Keeping in mind that the loop runs as fa
Thanks, Ian.
I appreciate the explanation.
Certainly I’ve understood the idea of late as it was inevitable that while
developing and testing my TDMA MAC I made mistakes and scheduled packets for
transmission in the past :0)
The underflow is a little more mysterious. At the request of Nate, a s
Steven
Underflow is a TX error phenomena, not an RX one. It is signaled when the local
buffering of TX data in the USRP becomes empty whilst the USRP tries to
continue to transmit.
Late, on the other hand, is signaled when a TX command contains a time that is
later than the USRP’s local clock wh
Hi Steven,
If you are able, can you please post an application/code that demonstrates
this ? Without seeing the code, its nearly impossible to debug the issue.
What version of UHD are you using?

Nate Temple

Hi,
I have been scratching my head for a while on this one…
I have made a TDMA radio that has a simple 4 slot cycle with a relatively low
duty cycle (slots are 40% and the remaining 60% of the cycle the USRP is idle).
A radio transmits in it’s “owned” slot and receives in all others (3 of them)
