Hi Aditya,
just in case the problem still exists, you might miss something like this in
your cmake files

Changing GR_FIXED_BUFFER_SIZE from 32k to 128k solved the problem, but
at the cost of quite a slowdown.
I think you can also change this per block. In GRC there is a Max.
Output Buffer field for each block. Maybe, that does not

That said, I'd bet that the issue is that CMake is not linking the RDS

CMake has settings to correct that, which I can pass on if this is the issue;
it's an easy fix to some CMakeLists.txt files.

Hi all,
Clayton and I worked on the FM RDS project over the last weeks. I think
that the receiving side is in a pretty good state now. It works well
with the RTL SDR.

So you receive some packets or none?
The problem is that when I change gain in the USRP sink nothing

Yes, I receive hopefully. But the packer error rate is too high. I went
through different configurations and gains. And finally I see that the
problem is the transmission side. The gain does not have any influence on the
error rate.

The problem is that all frames are dropped. The copy paste of the

Did you play around with the gain and see if that helps?
Is frame detection working or are you just streaming samples into the
flow graph that make absolutely no sense?

Sorry, but It seems like you did not transmit ever, as I look in .grc files.
As such, none of them send OFDM blocks...
For example in ofdm_rx. you have a chain of operations, good and working.
However there is nothing like

All work, but do not transmit regularly. In ofdm_tx. smt. is being
transmitted for a sec then the led A turns of again.
It crashes? Underruns? Overruns? Are

it looks like receiver is working. I think so, because I receive/see
around 30 packets in wireshark. And the led C is on.
Great! I never looked at the leds,

That is very weird.
I try gr-digital/examples/ofdm$ sudo ./benchmark_tx.py, and works, but
ofdm_tx one fails.
May be I did not get correctly what you mean with 'pushing

Yes, but at least you have to change MAC and IP address in the start script.
Maybe enable promisc mode of the TAP
