Suggestions on how to deal with top_block?

GNU Radio
1

Hello,
I am new to GNU radio. I am trying to make modifications in
benchmark_rx.py, such that when there is keyboard interrupt, it will
call
benchmark_tx.py. While doing this, I got an error which read multiple
instances of top_block are not allowed. I read the previous posts, and
am
aware this a GNU radio defect. However, I was wondering if there is any
way
of terminating the top_block instance of benchmark_rx before
benchmark_tx is
called, when there is a key board interrupt, so that this problem would
not
arise? Thanks.

Prasanna.

You can use the Python ‘del’ operator to force the top block instance to
go
out of scope when you want it to.

This issue will go away with the release of 3.2 (and on the development
trunk prior to that).
