Re: [Discuss-gnuradio] Synchronization between two E100 devices

[ziyang]

Hi Nick,

Thanks for your reply. In my application, a microsecond-order accuracy 
will be enough for the synchronization right now. But I didn't manage to 
issue set_time_now() to the other usrp because it seems only the usrp of 
the host device is accessible. So I was wondering if there is a way to 
access another e100 from the host device?

Thanks,

Terry
