[Discuss-gnuradio] Synchronization between two E100 devices

[ziyang]

Hi everyone,

I'm trying to synchronize two E100 devices, both connecting to the 
ethernet. According to the Synchronization Application Notes of UHD, 
there are a couple of methods to do it. But the problem is that I don't 
have access to either an external GPSDO or a reference clock signal.

I tried to access both devices by providing the IP address of 
uhd_usrp_source/sink, then set the time of them using the set_time_now() 
method. But it turned out that another m'board is not accessible to the 
host device.

So I was wondering, under this circumstances, is there a way to 
synchronize the device time of two E100s?

Thanks in advance,

Terry
