I want to capture Lora trace using 2 antennas that located in port A:RX2 and
B:RX2 then save the date in a file.
I created a simple Gnu Radio flow-graph. In USRP source, i add serial + 2
channel + freq + gain.
The problem that i can not save the data in a file.
I got error “Port is not connected”
Can any one help me?
