Hello,
I'm experimenting with the MIMO capabilities of the N210s with WBX
daughter cards and seeing how far I can get before I need the MIMO
breakout cable or GPSDO.
One of the first things I'd like to see is if both receivers on the WBX
daughter card can run at the same time (TX/RX and RX2).
Unfortunately, if I add two USRP source blocks with the same IP to my
flow graph and try it out, I get D's on the output.
According to
http://files.ettus.com/manual/page_general.html#general_ounotes, it
seems that I'm getting "discontinuous packets" and are subsequently
dropping data (which I can confirm). I assume it's because I'm
receiving data packets with the same source address, and probably
duplicated sequence numbers which GNU Radio thinks are discontinuous.
Is there a way around this? Is this a bug? It seems if I have the
bandwidth and physical hardware, I should be able to leverage those
capabilities, no?
This USRP and my workstation are connected through a switch, but if I
add a separate identical N210 with WBX to the switch, I get both sets of
data, so it's not a bandwidth issue.
