[Discuss-gnuradio] guided tutorials - problem with tutorial 3

[Jacqueline . Walker]

Hello,

 

Trying the tutorial three – python in gnu radio and the ‘if_else’ mod file. I get this run-time error even with the tutorial/solutions file so it might be a build thing.

 

Basically when it runs with the added if val == 1: block it raises an

Attribute error top_block_sptr has no attribute named analog_sig _x1_source block – (sorry not correctly copied but you get the idea hopefully) – in other words it does not recognise the analog signal source that you have and that you are trying to modify the freq and/or amplitude of under control of the simple if/else using the probe_signal variable as outlined in the tutorial.

Is there something missing in the build or is it some error in the file/instructions in the tutorial?

 

Thanks

Jacqueline
