[USRP-users] Configure send_buff_size in N321 USRP

Hi, I am trying to increase the buffer size in tx. According to https://files.ettus.com/manual/page_transport.html,   it seems that we can change the default send_buff_size by specifying value in device arguments. I tried the following configuration: uhd::usrp::multi_usrp::make('addr=192.168.12.

[USRP-users] how to use a usrp b210 with external gpsdo and nmea0183 as clock source

hi there, i am trying to get my GPS to work. setup is a b210, external pll-gpsdo bg7tbl connected to a nmea0183 anteńna and a vk-172 USB-GPS-mouse. i can get data from the usb receiver but in cgps there is no PPS and no 3D Fix. Now the question: can i activate my usrp to communicate with the e

Hi Marcus, thanks for your reply.No, I am not on MacOS. I am using Ubuntu. How can I configure send buff size in Linux?I went through the uhd library but could not see it had any limit on buffer size. So, very strange where the buffer limit comes from. How do I measure the buffer?I created a pa

[USRP-users] Re: Configure send_buff_size in N321 USRP

Thank you Marcus.I originally thought that there might be two levels of buffer, one in device and one in host, and the one in host was bigger and could be configured by user, but after I checked the UHD library, I couldn't find the host-side buffer. So, I agree with you that the host sends the
