Re: [Discuss-gnuradio] clock synchronization by message passing

[John Malsbury]

The GPSDO can provide an "internal" 10 MHz/1 PPS signal.  I'm not sure if that's what you meant or not:  https://www.ettus.com/product/details/GPSDO-KIT

AFIAK, you cannot set the time of a USRP with a message. You may be able to use the XML_RPC block in gr-extras to call the function if it is exposed through gr-uhd.

how can we set the time of usrp by sending it message. I know there are function to (usrp.set_time_now()) do this from from top block variable but can this be done by sending message at usrp port . 

We can give internal reference signal of 10MHz  but is there also a way to give pps signal internally i.e. without using any external hardware.
