Recv and send frame size


#1

Hi all,

is there any possibilty to increase the send frame size ans recv frame
size of the USRP from the host?
Thanks

What are you using to transmit and receive? Are you using the
benchmark_tx
and benchmark_rx files? (I assume that frame size and packet size are
synonymous).

If so, you can use the “-s 500” option to set the frame size to 500
bytes
in benchmark_tx. There is no need to set the frame size in the receiver.
The frame size is encoded by the transmitter into the header, and the
receiver reads it off that.

hi Aditya
I was trying to figure out the throughput of the E110
I set the bitrates to 50kbps and samples_per_symbol to 5,also I use the
gmsk mod_demod
but on the tx side, I found out the bitrate is larger than 50 kbps,can
you help me to figure this out?
here is the method I tested the throughput:
I send 200 packets and measure the time it consumed

and another phenomena is ,when I send 200 packets ,the rx side always
receive 197 packets,why?where are the other packets?

If you haven’t already spent some time inside that documentation tree,
it’s a good investment of your time.
