Josh,
I applied your changes below for WBX. Yes, a transmitter doesn't see
packets from itself anymore. However, in my experiment, two nodes using
tunnel.py could not talk to each other anymore. So I changed the code
back and two nodes resumed their communication channel.

Josh,
Thanks for the clarification.
Does it mean that, by this hacked code, turning off RX mixer at
transmitting time happens on FPGA? Or does it happen at UHD on the host
side?

Thanks for the info. I wasn't sure how to shut off demodulation in
software. I ended up finding the "valve" block

Are you sure you're really using TX/RX for receive? As the link Josh
supplied says "The user may set the receive antenna to be TX/RX or RX2.

I just got my shiny new N210's last week. I've setup UHD and GnuRadio
from GIT. I've done some simple tests and have been able to transmit
data from one N210 to the other. Today I started working on
bidirectional communication. For my simple setup I've got 2 N210's
each with an RFX2400 (using TX/RX
