[Discuss-gnuradio] Missing a required length tag while doing GFSK demodulation

[Sumit Patidar]

Hello,

I am trying to use the chat app of examples -> tutorial 5 of gnuradio tutorials. I have used GFSK block to modulate and demodulate the signals but receiving the following error.

Terminal output:

----------------------------------------------------------------------

Tag Debug: 

Input Stream: 00

  Offset: 0  Source: n/a     Key: tsb_tag   Value: 192

----------------------------------------------------------------------

gr::log :FATAL: repack_bits_bb0 - Missing a required length tag on port 0 at item #192

thread[thread-per-block[11]: <block repack_bits_bb (19)>]: Missing length tag.

-----------------------------------------------------------------------------------------------------------------------

Please help me with this.

Thanks in advance!

Regards,

Sumit
