[Discuss-gnuradio] Using signals for reading from the Ethernet port

[Natalia Olano]

Hello everyone,

Is it safe to use signals in the gnuradio framework?

I modified tunnel.py in order to read a control packet on the Ethernet
port asynchronously using SIGIO. The Ethernet packet could eventually
arrive when we are performing channel sensing or sending a packet and
interrupt that. Will the system recover if I just catch the Exception
and work the next time when I need to do carrier sensing and send a
packet? I think I am seeing some issues on this, for example, sensing
a carrier when there is no carrier present anymore. Besides, the code
on the signal handler is quite lengthy, is this likely to disturb the
gnuradio framework?

Thanks for your help
