Hi,

I get the following error connecting 'OFDM Serializer' (GNU Radio block with 
complex output), to my own Python block 'blsd_dec_bfb' (with complex input)

"ValueError: itemsize mismatch: ofdm_serializer_vcc0:0 using 8, blsd_dec_bfb0:0 
using 16"

This is the code in the beginning of my block

"class blsd_dec_bfb(gr.basic_block):
    """
    docstring for block blsd_dec_bfb
    """
    def __init__(self, num_packets=1, K=50, K2=20, kA1=4, NA1=8, 
num_carriers=64):
        gr.basic_block.__init__(self,
            name="blsd_dec_bfb",
            in_sig=[numpy.complex],
            out_sig=[numpy.uint8,numpy.uint8,numpy.uint8])"

the xml is

"... <sink>
    <name>in</name>
    <type>complex</type>
  </sink>
  <source>
    <name>bA1</name>
    <type>byte</type>
  </source>
  <source>
    <name>bA2</name>
    <type>byte</type>
  </source>
  <source>
    <name>b2</name>
    <type>byte</type>
  </source>..."

The colours match in the GRC, and it lets me run it (i.e. no complaints about 
type mismatch before run-time).

I hope it is just a silly mistake. Can anyone help?

Regards,

David
