Hi,
> OK I understand that. But is there any solution which permits to reset that growing propagation delay ? How to reset the flowgraph buffers without killing the application and restart it ? Is there any method that permits to purge and resync buffers of the flowgraph ?
The USRP supports timestamps for RX and TX.
So you get tags for when data was received / is supposed to be transmitted.
Using a custom block to modify the RX tags into TX tags ( to change
the RX timestamps to TX timestamps a bit into the future ), you should
be able to achieve a constant controlled latency.
Cheers,
Sylvain
