hi folks,
I am using BENCHMARK_TX.PY, BENCHMARK_RX.PY to test the
transmission and reception of signals. I have doubts regarding the
outpu that is appearing on the screen.
>>> gr_fir_fff: using SSE
socket(PF_PACKET, SOCK_RAW, htons(0xBEEF)): Operation not permitted
eth0: socket: No such file or directory
Requested RX Bitrate: 100k
Actual Bitrate: 125k
Warning: Failed to enable realtime scheduling.
1) What is the SOCKET part in the output
Running as root should resolve this. But this should also be resolved by
means described on the wiki- page.
2) What is the difference between Actual Bitrate and Requested Bitrate
The actual bit rate is calculated from a couple of parameters, and I
think actual bit- rate is "close enough" to the requested one, given
that there are some limitations regarding decimation/interpolation rates
and so forth...
3)How to enable real time scheduling
There are some ways to elivate the privs. The quickest way is to run the
aplication as root. This is not the recomended way, which has something
to do with setting some privlegies and execution bits for an
application. More information should be avaliable in the archives, and
on the wiki- page.
