Hello again, So, I am still getting the same error with the example "txrx_loopback_to_file" so instead I tried to run "tx_waveforms" (the only other example that supports multiple channels). I give the following command: ./tx_waveforms --freq 2.60e9 --rate 7.68e6 --gain 60 --args "addr0=192.168.1

Hello, Thank you Jorge and Ali. I am using UHD 3.14. I am trying with the example now and as I mentioned specifying "addr0 addr1" gives an error but I actually have modified this code to send a specific file and added a "repeat" tag. Do you think it would not hang if it's not a continuous transm

Hello fellow N310 users. My lab has 6 N310's all operating and streaming to a single data server (10 Gbe links). We use GNU Radio for everything. The software is great for controlling multiple devices with many antennas easily (highly recommended). My experience with native C++ UHD driver commands

Hi, Neharika and All, I met some problems on controlling 2 N310s too. But first of all, the argument "second_addr" indicates the IP addr. of the second SFP+ port on that device, and is set in the case of dual 10G streaming. I think the first way you wrote is the right way to access the 2 N310s, e

Hello, I am using two N310 USRP's to create an 8x8 MIMO setup. But, I am unable to make both of them work together. I am using an example program from the UHD driver - txrx_loopback_to_file. I give the following command: ./txrx_loopback_to_file --tx-rate 7.68e6 --rx-rate 7.68e6 --tx-freq 2.60e9
