I see but no, I'm not processing a finite number of samples. I'm generating a message periodically with a Message Strobe, then the message is encoded and modulated as a WiFi signal using the modules in: https://github.com/bastibl/gr-ieee802-11. Now, I'm trying to detect the signals myself and then decode them with the blocks from the same gr-ieee802-11 repository. The block I'm implementing in python looks like this:
class short_sync_blk(gr.sync_block): def __init__(self): gr.sync_block.__init__(self,name='Custom short preamble detection', in_sig=[np.complex64], out_sig=[np.complex64]) <+define some variables+> def work(self, input_items, output_items): print(input_items[0]) # Here is where I see that, after one iteration, input_items[0] is filled with zeros <+some processing+> <+insert a tag+> output_items[0][:] = input_items[0] self.consume_each(len(output_items[0])) return len(output_items[0]) Is this enough? Or should I put all the actual code in here with all the connected blocks? Thanks in advance. Best regards, Verónica
