Hello, I am trying to implement a half-duplex system with one antenna, preferably using just one port in the USRP device. I have noticed that the port that is labelled as TX in the B200mini can also receive (the same as the TX/RX port in the "normal" B200). My question is, is it possible to change

Marcus, thank you for that advice. I was concerned that making the calls through the gr-uhd would give the same problems I was experiencing with the tagged stream but upon closer inspection it makes calls directly to the uhd::usrp::multi_usrp. Upon second glance using the gr-uhd would be the b

Hello Dev Joshi: Is the N200 directly connected to the host computer? What are the IP addresses and netmask of the host and the N200? Do you have a gateway address configured? Earlier, Marcus suggested trying to augment your device string with "type=n2xx". Did you try that? --Neel Pandeya On

Hello, I have an E320 that I'm trying to get to auto-boot when power is applied (so the button doesn't need pushed). I followed instructions here (https://kb.ettus.com/E320_Getting_Started_Guide#Enable_Auto_Booting) to set the autoboot flag, but it isn't working (not automatically booting when
