Re: [Discuss-gnuradio] Problem with RX OFDM through the network

[Maicon Kist]

Well, Im trying to figure out why the quantity of numbers received is way smaller than the quantity generated.

So, I did something more simples:

- I modified the  rx_ofdm.grc file (in gnuradio/examples/digital/ofdm). I simple added a “Tag Debug” right before the second block in the chain (Stream to Tagged Stream). 

- Even in this example the quantity of numbers generated is 10x the quantity of numbers recoved in the end of the flowgraph.

It seems to me that the scheduler prioritizes the ‘Random Source’, calling it several times more than the other blocks in the flowgraph. Is there a way to fix this?

Best Regards.

Hello

I manage to solve the problem  of

gr::log :INFO: packet_headerparser_b0 - Detected an invalid packet at item 2112

gr::log :INFO: header_payload_demux0 - Parser returned #f

by replacing all ZMQ REP/REQ by ZMQ PUSH/PULL blocks. 

Now, my only problem is that the Random Source Generator is generating (dã) way more numbers that are being received in the final part of the flowgraph (Tag Debug).

 Any hints about this too ?

Hello list,
