Re: [Discuss-gnuradio] problem with packet decoder for gmsk

Lot of people around here at IIT Bombay also complain that there is no data at the output of packet decoder.

Try replacing the random source (binary output) with a signal source(set it to float). And try to plot the output of packet decoder(float output) in a gui sink. That should work, because there exists a working example among GNU Radio example which uses this flow graph.

I can't say what is going wrong in your flow graph. But I kind of feel that we need to dig into the implementation of the block to know what is going wrong.

Thanks Martin, i tried with replacing uhd  with channel model, I had good
signal at the receiver after gmsk_demodulator but I'm facing the same
problem i.e with packet decoder no out put after here.

Even I tried with removing uhd and directly connecting them even though I
have the same problem like below shown

Random_source=>Packet_encoder=>gmsk_modulator=>rational_resamlper_1=>--!

!

!---------------------------------------------------------------------------------------------------------------------!

!---------=>rational_resampler_2=>low_pass_filter=>gmsk_demodulator=>packet_decoder=>scope_sink/file_sink



no output/signal after packet decoder,what would be the problem which side I
have to concentrate to remove the error.


Thank you
