Hi Sriram , Did you managed to solve your problem? I'm doing the same, but i don't have any errors. The connecting process is ok,
but i think there is a conflict between the "call_back" of the receiving path and the "eval" function of the sensing path? have you faced some problem like this? if yes, please inform how did you solve it. regards, Sriram Krishnan-3 wrote: > > Hi, > I am trying to write an application which senses spectrum > (usrp_spectrum_sense.py) and transmits/receives signals.
