Hi All,
I have a flowgraph which has both a
uhd_sink and uhd_source. I also have the samp_rate for both of
these linked to a QT Chooser to enable me to select valid
sample rates dynamically at runtime.
If I change the sample rate from 500kHz to
12.5MHz I can repeatedly generate the following error and the
transmitter stops:
read[thread-per-block[9]:
<block gr uhd usrp sink (8)>]: RuntimeError: On node
0/DmaFIFO_0, input port 0 is already connected.
If I change between sample rates closer
together (12.5MHz and 3.125MHz) this problem does not appear.
Has anyone else experienced this, and/or
know of a solution ?
Thanks,
Nigel
