Dear List,

I'm beginning with gr-mac. ( I need
complex/float data to process but some blocks give message as output
Stream to PDU*). I did try using *Message Source* to convert form
to complex but there was error with the ID:
*NameError: global name 'blocks_message_soure_0_msgg_in' is not defined

Also, *PDU to Tagged Stream* takes *message* as input. The *Message
Sink*was used but the similar error happened:

Am I right using *Message Source* and *Message Sink*? If yes, how could
fix these error? If no, which blocks should be used?

Hi Tom, and all,

I've had a look at *PDU to Tagged Stream* block.
Regarding to adding tags, both this block and *Burst Tagger *contains
add_item_tag() function. Which block inserts the main stream tags? I
quite under stand what *Burst Tagger* does since it contains both
add_item_tag() and get_tags_in_range() function.

Have a read of:

That will hopefully give you a better understanding of the tags.
