[Discuss-gnuradio] Costas parameter in DPSK2 grc block not in .py?

[Benjamin Lonske]

When I try to use the DPSK2 demod block in grc, I get the below error. The issue seems to be that the grc block has different arguments than dqpsk2_demod() in dqpsk2.py (see below). Am I missing something here? I am using the gnuradio version 3.3.0.

Thanks,
Ben
