[Discuss-gnuradio] Problem with Probe MPSK SNR under GRC

[Tachwali, Yahia]

Hello Guys,

Was anyone able to get Probe MPSK SNR block to work under GRC environment. I 
could not get it to work. I used it with the function probe and used the 
"noise_variance" method and the appropriate block ID values but the problem is 
that upon running, it is not updating the value inside the probe function 
block. I changed the rate from 0.1 , 1 , 100 Hz but no luck.

Please let me know what could be missing here. Thank you alot

Kind regards,
Yahia Tachwali
