1-I installed radioconda + USB driver
2-to capture LoRa trace using USRP B210, I type “rx_samples_to_file
--freq 915.0e6 --rate 1e6 --gain 20 --duration 10 --file lora_rx“
3-Now i want to capture Lora trace using 2 antennas that located in
port TX/RX and RX2
How can i do that?
Two points:
(1) For a given "side" the receiver chain is connected EITHER to the
TX/RX port OR the RX2 port. If you want multiple RX antennas, you'd use
the RX2 ports on either "side/channel" of the B210.
(2) The rx_samples_to_file example only deals with a single channel--you
might want to modify the rx_multi_samples example, or construct a quick
Gnu Radio flow-graph to do what you want.
