Hello Guys
I've created a customized block that takes in a number of input items and once that number of
input items surpasses a certain number, 1024 of the input items are
taken and stored into a list, and then those items are converted to dB
and lastly compared to a threshold value. If any of the
values are greater than the threshold value, a message is printed
indicating a signal is present, and if none of the values are greater
than the threshold, this is indicated with a message stating "No signal is present". I've tested the block in both simulation and currently, I'm testing the block over the air using the N210. The block performed correctly in simulation, however, over the air, the block gives a response of "no signal present" regardless of the input. The error message "
python: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0
also printed during runtime. Any suggestions are welcome. Both the simulation flow graph and the flow graph used over the air are attached.
