Re: [Discuss-gnuradio] Rx dBoard has empty serial

[mleech]

What version of UHD are you running?  And what approximate age are the WBX?

The Rev 3 WBX is somewhat different than Rev 2, so you need to make sure that you have the latest host-side UHD and matching firmware to properly support Rev 3 WBX.

There was a (transient) bug in the calibration routines that was found last week, but it's fixed in the most recent UHD host-side.

I used the cal routines on my USRP2+WBX just this past weekeend and they worked just fine.   So perhaps you have the transiently-broken version of UHD.

Perhaps Josh can comment--I don't have the GIT tags of the broken instance at my fingertips right now.
