Basic usage
Desciption
In this tutorial we'll demonstrate how to navigate from the COSMOS sandbox to a single SDR on a node and run an application to read samples from the SDR.
Prerequisites
Before getting started you'll need the following:
- sign up for a COSMOS account
- create a reservation for sandbox 1 using the scheduler.
- some minimal knowledge or interest of Linux
Set up
- After your reservation request has been approved, you'll receive access to the sandbox1 console.
Open a terminal into console.sb1.cosmos-lab.org with a tunnel set up from localhost:5000 to srv1-lg1.sb1.cosmos-lab.org:9002

- We can see the available nodes under this sandbox using the omf stat -t all command. The nodes list below should coinside with the Inventory/Status page.
nilanjan@console:~$ omf stat -t all ----------------------------------------------- Node: srv1-lg1.sb1.cosmos-lab.org State: POWEROFF Node: srv2-lg1.sb1.cosmos-lab.org State: POWEROFF -----------------------------------------------
- For this example we'll use the node srv1-lg1.sb1.cosmos-lab.org and load the baseline-sdr.ndz image onto it. This image already has the applications pre-compiled and drivers installed.
console:~$ omf load -i baseline-sdr.ndz -t srv1-lg1.sb1.cosmos-lab.org
After the image is successfully loaded turn on the node, give it some time to boot and then ssh into it.console:~$ omf tell -a on -t srv1-lg1.sb1.cosmos-lab.org console:~$ ssh native@srv1-lg1.sb1.cosmos-lab.org
- Once you're in srv1-lg1.sb1.cosmos-lab.org configure the network interface so it can talk to the N310's data interface.
sudo ifconfig enp1s0 10.115.1.1 netmask 255.255.0.0 mtu 8000
Run uhd_find_devices' and check if the N310 is detected
native@localhost:~$ uhd_find_devices [INFO] [UHD] linux; GNU C++ version 7.3.0; Boost_106501; UHD_3.13.1.0-0-unknown -------------------------------------------------- -- UHD Device 0 -------------------------------------------------- Device Address: serial: 315A35A addr: 10.115.2.1 claimed: False mgmt_addr: 10.113.2.1 mgmt_addr: 10.115.2.1 product: n310 type: n3xx -------------------------------------------------- -- UHD Device 1 -------------------------------------------------- Device Address: serial: 3176DF7 addr: 10.115.3.1 claimed: False mgmt_addr: 10.113.3.1 mgmt_addr: 10.115.3.1 product: n310 type: n3xx
The above output enumerates all the SDRs that were detected. Use the uhd_usrp_probe command with a mgmt_addr to get more details on a specific n310.

Run application
From root/SPECTRUM_VIEW directory run the pre-compiled application that can read samples from the N310.
native@localhost:~$ cd SPECTRUM_VIEW/ native@localhost:~/SPECTRUM_VIEW$ ./app_read_n310_samples INFO 11:51:08.262 (main.cpp:623) - Starting command server at 5180 INFO 11:51:08.262 (main.cpp:175) - Starting websock server at 9002 ...........
In short the application runs a server listening for commands. Just to briefly demonstrate the functionality, open the spectrum_view.html file in a Chrome browser, this will issues commands to configure the N310 and display a short spectrum width. When the viewer is first opened, you should see the text CONNECTED below the plot.
Keep the default values for RATE, FREQ, GAIN and click on the HALTED button. This should display the spectrum if all went well.
