you mustn't do that! Your np.mean depends on the length of input_items, and that will be different every call. So, this is not the way to go. I don't think this will all fit in the comments here. Would you mind writing an email to the [email protected] mailing list, with your block code (and because people won't know what we discussed here, a short description of what you want to do!)?

Hello @MarcusMüller. I am coming back to you because it has been one week now and I still did not manage to write the blocks to make what I want. I have written a block cmp_avg_pow which work function computes output_items[0][:] = np.mean( input_items ) (np being short for numpy) and another block, custom_thres which work function just make output_items[0][:] = blocks.threshold_ff(0.0, input_items[-1], 0). In my main function, I connect complex_to_mag_squared blocks to both cmp_avg_pow and custom_thres, and the output of cmp_avg_pow also to custom_thres. Nice day,Alex

| Mar 8, 2022 at 9:39 | comment | added | Marcus Müller | I already answered that. You need to write a block. | |
| Mar 8, 2022 at 9:38 | comment | added | aheuchamps | @MarcusMüller oh okay I thought it was like that I had to do. I am going to search how to access the value rather than access the whole block. Thank you for your answer :D | |
| Mar 8, 2022 at 9:36 | comment | added | Marcus Müller | you did not print values, you printed a block. Not how GNU Radio works! The samples are not available at the level where you construct the flow graph – you only interact with them using blocks. So, you need to write a block. tutorials.gnuradio.org has a good introduction to doing that :) | |

@MarcusMüller I tried to just print the values given by the complex_to_mag_squared block, and was expecting to see some float values. Insted, I got something like this all_cmpl_to_mag2[0] = <gr_block complex_to_mag_squared (4)>. I do not understand how to get the value from there ?
