hi
I have been trying to make the USRP work as a relay for quite some time and not
been able to do so. I want to transmit whatever data the USRP has received.
I have been working on rx_voice.py for reception of my audio files.The flow
graph is connected like :
self.u = usrp.source_c(0,decim);
fg.connect(self.u, self.chan_filt, self.packet_receiver)
The reception of packets is perfectly fine in this case. Now, the curious thing
which is happening is that when i also make the usrp as the sink and connect
the flow graph as
self.dst = usrp.sink_c(0,interp);
fg.connect(self.u, self.chan_filt, self.packet_receiver)
fg.connect(self.u, self.dst);
then i also stop receiving any packets. I am not able to understand why is this
happening. At least the reception of the packets should not have changed, leave
aside the retransmission part. I am using a single Flex 900 board so i dont
think that might be causing the problem.I dont think that making the connection
as
Data from usrp ----> Data to usrp
is wrong. If its so,then let me know and is it necessary to put some kind of
filter between the 2 to make it working. Also, i dont think that making the
flow graph as
Data from usrp----> data demod -----> data remod ------> Data to usrp
would make any difference. I also want to retransmit at a different frequency.
So, is it necessary to demod and remod or whether just setting the usrp at that
retransmission frequency would solve my purpose.
Reading from the previous archives i have found that it should not be much of a
problem in making such a thing work but somehow its not working in my case.
I would be very grateful if somebody could help as its been quite long since i
am stuck onto this problem.
Thanks
