Re: [Discuss-gnuradio] gr-pyserial

Hi Julian,

blind guess: gr-pyserial is from 2012 and thus likely uses GNU Radio 3.6.something, whereas you're trying to use it with a more modern version of GNU Radio, whose python block object doesn't have the num... argument.
I think the easiest (and most sensible) solution to this is honoring jmalsbury's work by using an up-to-date version of GNU Radio, employing "gr_modtool nm" to make a new module, add a new block to that using "gr_modtool -l python add" and then copy&paste over most of the code into the skeleton you've just created.

Best regards,
Marcus

Some who maybe has any experience with gr-pyserial could help me? Is there
a code error or is something wrong with gnuradio?

Thanks all for your help
