The hackrf module for example has a special value of 0.0 for the set_bandwidth call that basically mean "auto-set".
When you change the sample_rate it goes to automatic unless you manually set a specific bandwidth. Cheers, Sylvain _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
