Not sure where this really belongs but figured I would ask it here. I have been having consistent issues trying to interface different applications over udp. Sometimes packets will go through and other times nothing. And sometimes certain applications will be able to see the packets and other times not.
For example, I have been trying this combination just for test purposes:
Sdrpp → udp dump 7355 at 48khz at 127.0.0.1 → gr_satellites and I don’t see any packets come through.
Sdrpp → udp dump 7355 at 48khz at 127.0.0.1 → nc -l -u 127.0.0.1 7355 and I don’t see any packets come through.
Sdrpp → udp dump 7355 at 48khz at 127.0.0.1 → generic python socket application. I see packets come through.
Not sure what is the problem and I have tried other applications such as sdrangel and encounter similar issues.
