Its an XCVR2450, but I do *not* start any 'packet' transmissions. All I do, is to start both the flowgraphs, and just listen for packets.

In which case, the TX side is running--even if you aren't sending any *data* bits, it's still transmitting, and blocking the receiver.

You'll have to get more sophisticated about half-duplex flow management, using tagging to tell UHD to turn on/off the TX side.

Josh probably has better words of wisdom on this than I.

Hi Marcus,

I'm working with Apurv, so I'm going to chime in here :)   

I tried doing some searching on the mailing list, but I wasn't really able to find much on this.  I also thought that auto tr would handle this.  I found a post from Josh on the mailing list that said Auto TR is always enabled in UHD.
