Re: Help required tunnel.py

GNU Radio
1

I have installed deb package of GNU radio 3.2.2 for Ubuntu 9.04 and
works fine, with openSUSE 11.1 I try tarball and everything is OK, for
openSUSE there’s a rpm package of GNU radio 3.1.3 avalaible in
Search it’s ok too.

Try doing this step by step
Run tunnel.py, in Ubuntu sudo tunnel.py -f 24xxe6 -c x x can be whatever
you want.

You will see an output asking to allocate gr0

Set an IP address with sudo ifconfig gr0 192.168.200.1 netmask
255.255.255.0, don’t press enter

Wait here and go to next PC and repeat the same, but press enter when
both PCs are ready

If everything is fine immediately in console you will see RX and TX
because of communication is beginning, is there’s only TX messages we
have a problem, if BBBB is in your screen, it means back off no carrier
sensed, try to change it with -c option.

Again good luck

Juan,

Thanks a lot for your response. I tried stopping at the ifconfig stage
and
wait for both PCs to be ready before hitting enter. But all I saw was TX
and
no RX. Do you have any idea where the problem might be?

Hi,
I have successfully run digital folders tunnel.py.
However, I am not receiving anything when i run the ofdm folder
tunnel.py.
Whereas the benchmark_ofdm_tx+rx.py is running perfectly.
I have varied almost all the available parameters but to no avail.
Please help me out.
Thanks in advance.
Chuck.
