My application requires a custom GRC block. Everything seems to work Ok except in the last stage where we are supposed to create the xml file so that the block is visible in the GRC gui.
When I instantiate the custom block in GRC GUI and double click on the block, I see several errors such as "Type Complex is not a possible type" in the dialog box that pops up.
I thought Complex is one of the supported types in gnu radio. Why does that warning show up?
Here is the small excerpt of the xml code:
<!-- Make one 'source' node per input. Sub-nodes:
* name (an identifier for the GUI)
* type
* vlen
* optional (set to 1 for optional inputs) -->
<source>
<name>EstimatedCh</name>
<type>Complex</type>
</source>
