[Discuss-gnuradio] Help With OOT - QA Test Ok - Flowgraph not Working

[Luis Felipe Albarracin Sanchez]

Hello Everyone,

I am trying to build a controller which will allow to control output power of a signal according to some received variables.

I have build everything according to the tutorial:

https://wiki.gnuradio.org/index.php/Guided_Tutorial_GNU_Radio_in_Python

The python code of my block is as follows:

#The "Init" part  is as follows:

class fuzzy_mod_adap_ff_ff(gr.sync_block):
    """
    docstring for block fuzzy_mod_adap_ff_ff
    """
    def __init__(self,):
        gr.sync_block.__init__(self,
            name="fuzzy_mod_adap_ff_ff",
            in_sig=[np.float32, np.float32],
            out_sig=[np.float32, np.float32])

.

.

.

.

#The  part of the work function of the code  is as follows:

 def work(self, input_items, output_items):
        in0 = input_items[0]
        in1 = input_items[1]
        out0 = output_items[0]
        out1 = output_items[1]

        for i in range(0, len(in0)):
                X1= in0[i]
                Act_Mod= in1[i]
                self.Normaliza(X1,Act_Mod)
                out1[i], out0[i] = self.Fuzzy()

        return len(output_items[0])

After this I ran the QA Test and the results are:

address@hiddendn:~/Fuzzy_GNU_Blocks/gr-FuzzySyst/python$ python qa_fuzzy_mod_adap_ff_ff.py
(38.653770446777344, 61.346229553222656, 38.653770446777344, 61.346229553222656)

OK

The QA Python file is attached, just in case.

Nevertheless, when i try to run  the block in  the following  flowgraph:

The result when i run the Flowgraph is:

The New Mod and Power Out values shows first "0" and after 1 minute or more, change to the value in the previous image.

Nevertheless when i change the variables in the QT Gui, the outputs (New Mod and Poer Out") the don´t change, and if they do they do it after 3 minutes or more.

I dont know what could be the problem because the QA test runs perfect but in the flowgraph it does not.

Just for the record i put a "throttle block" and nothing changed.

I would appreciate all the help you can give me regarding this.

Kind regards.
