Hi Eric,
You can find the example here:
http://cs.ucsb.edu/~veljko/downloads/tx_ofdm_flex.tar.gz
The example (benchmark_ofdm_tx_new.py) changes the number of carriers
(from 50, to 100, 150, and so on) after every 300 packets sent. It can
use either set_ofdm_parameters or set_ofdm_parameters_high,
Update:
I moved the reconfiguration one level up, to transmit_path.py and it
works for high interpolation values (low bit rate), but still hangs
for the low ones.
I'm quite puzzled now, it seems that lock() - unlock() gets stuck when
there's too much flow going on.
cheers,
Veljko

Hi,
I have a similar problem in my code.
I modified benchmark_tx.py from gnuradio-examples/ofdm and ofdm.py
from blks2impl so that I can change the number of active subcarriers
on fly.
In the packet sending loop of benchmark_tx I periodically do the following:
lock the top block (tb.lock()), cal
