Re: [USRP-users] B210 TX from file of complex samples

A classic here would be if there was a network-attached USRP that is also found by your PC, and then used without you noticing. Could that be the case? What do you use in the "device address" field of the UHD USRP Sink? Best regards, Marcus (the other) On 15.01.21 09:28, Marcus D. Leech via USRP

I believe the SPP argument can also affect the transmit SPP. If you call tx_streamer.send() with buffers larger than SPP, then it will split them into SPP-sized packets. tx_streamer.get_max_num_samps() should return the currently configured SPP. Wade On Fri, Jan 15, 2021 at 8:06 AM Ephraim Moges

What version of UHD are you using? Different UHD versions provide different filesystems, which configure networking differently. - MLD On Fri, Jan 15, 2021 at 9:01 AM Mark D via USRP-users < usrp-users@lists.ettus.com> wrote: > Thanks Cédric, > > I used the networkctl status eth0 command that poi

Good Morning Mr. Fife, Based on the documentation the SPP is commendable for the RX portion only. For the TX portion I have been creating an array, with a size less than tx_streamer.get_max_num_samps(). Is the method I use to control the tx packet size incorrect? Sincerely, Moges On Thu, Jan

Thanks Cédric, I used the networkctl status eth0 command that pointed me to the file at /lib/system/network/40-eth0.network I then edited this file to remove the DHCP sections and set the address at 192.168.1.60/24. Looks to be working great, Mark -Original Message- From: USRP-users

Thanks for getting back to me on this, I'm trying to set the "management" port on the RJ45 connector. Our application isn't using the SFP port. Ifconfig returns the following ports: eth0 int0 lo sfp0 It's the eth0 port that I'm trying to set to a fixed address. I can configure this via the ser
