Re: Message to variable issue

Thanks for your support. I have tried this by setting the default freq variable to 10, but the message coming from zmq is still not converting to appropriate format. Could you please help me to rectify this issue?
terminal output:
sub_msg_source :error: Invalid PMT message: pmt::deserialize: malformed input stream, tag value = : 51
sub_msg_source :error: Invalid PMT message: pmt::deserialize: malformed input stream, tag value = : 51
sub_msg_source :error: Invalid PMT message: pmt::deserialize: malformed input stream, tag value = : 50
....

Hello Muhammad,

I think the messages are "text".  Try

float(freq) on the receive side.

Good Luck

Glen
