I try SBX and WBX but the result is the same. TX fails and RX succeed.
The following is the summary usrp2, operated in gnuradio 3.2.2 with
corresponding firmware download from ettus web can TX and RXusrp2, operated in
gnuradio 3.6.2 with corresponding firmware download from ettus web can RX but
fail to succeed.
The test program used are uhd/usrp2_siggen, benchmark_tx and benchmark_rx and
bbn80211_tx and bbn80211_rx.
I think the problem may be related with firmware in 3.2.2 version, but if it is
the problem it is hard to explain why it can RXThank you.

Which port is your antenna connected to? In SBX/WBX daughterboards, you can
only transmit through Tx/Rx. However, you can receive through both Tx/Rx and
Rx2.
This might not be related to your problem. But just checking.
Thanks,

Dear Guys, I encounter one strange problem, I can use usrp to receive
signal but cannot transmit signal. My usrp is USRP2 and gnuradio version 3.2.2.
When running ursp2_siggen.py, it do not return any error but when I use a
spectrum analysis, it shows no signal is transmitted.
When running benchmark_tx.py and bbn80211_tx.py, it also reports no
error, but there is no signal sent out. Do you guys have any advice?
Thank you.
