Recv_frame_size and send_frame_size

Hi all,

I have changed recv_ frame_size and send frame by typing uhd_usrp_probe
“addr0=198.168.10.2,recv_frame_size=4096, send:frame_size=4096”. I have
also change the MTU size on my host computer to 4096. After starting
gnuradio companion the frame size was set to 1472 bytes again. What is
hier the problem? How can I change the frame sizes permanently?
Thanks
AB

Parameters you pass to UHD like this are not persistent between runs,
the hardware is re-initialized each time so you must pass them each
time.

In GRC you would pass the parameters as per the example I’ve attached.
