Re: [Discuss-gnuradio] Losing samples in the flowgraph

Hi all

I labeled my block "ofdm_symbol_cutter", but he is not one out of the standard OFDM blocks. I wrote this block, because I want to isolate the sample loss problem.
I tested the flow with UHD source and the file source, so it's not only a simulation. There was all the times the same flow behaviour. I think there is a problem with the multi-threading or I understand something absolutely wrong.

No, I don't use udp.

Thanks for your help.
