findsdru

Status of USRP radios connected to host computer

Add-On Required: This feature requires the Wireless Testbench™ Support Package for NI™ USRP™ Radios add-on.

Syntax

radios = findsdru

radios = findsdru(IPAddress)

radios = findsdru(serialNum)

radios = findsdru(___,StatusOnly=logical)

Description

radios = findsdru returns a structure that contains the model number, IP address, serial number, and status of each USRP™ radio that is connected to the host computer.

radios = findsdru(IPAddress) returns information for only the USRP radio with the specified IP address.

radios = findsdru(serialNum) returns information for only the USRP radio with the specified serial number.

radios = findsdru(___,StatusOnly=logical) specifies the option to return the detailed status of the radio, in addition to the input arguments in the previous syntaxes.

Examples

Get Status of Connected USRP Radios

Get the model number, IP address, serial number, and status of each USRP radio that is connected to the host computer and has been set up using the Radio Setup wizard.

radios = findsdru

Checking radio connections...

radios=1×2 struct array with fields:
    Platform
    IPAddress
    SerialNum
    Status

Query the contents of the first element in the array.

radios(1)

ans = struct with fields:
     Platform: 'N320/N321'
    IPAddress: '192.168.20.2'
    SerialNum: '3202230'
       Status: 'Success'

Get Status of Specified USRP Radio

Use the radioConfigurations function to query the name, hardware, and IP address of any radio configurations you have saved using the Radio Setup wizard.

radios = radioConfigurations

radios = struct with fields:
         Name: "MyRadio"
     Hardware: "USRP X310"
    IPAddress: "192.168.40.2"

Get the serial number and status of the USRP radio associated with the first saved radio configuration by specifying the IP address. Set the StatusOnly flag to false to get the detailed status information.

findsdru(radios(1).IPAddress,StatusOnly=false)

Checking radio connections...

ans = struct with fields:
     Platform: 'X310'
    IPAddress: '192.168.40.2'
    SerialNum: '31D3D75'
       Status: 'Success'

Input Arguments

IPAddress — IP address of USRP radio

dotted-quad character vector

IP address of the USRP radio that is connected to the host computer, specified as a dotted-quad character vector.

Data Types: char

serialNum — Serial number of USRP radio

character vector

Serial number of the USRP radio that is connected to the host computer, specified as a character vector.

Data Types: char

StatusOnly — Option to get status of connected radios faster

true (default) | false

Option to get status of connected radios faster, specified as one of these options.

• true — Enable the findsdru to return the radio status faster.

• false — Enable the findsdru to get the detailed status regarding firmware compatibility, no response from the device, and other UHD errors.

For more information about the reduction in execution times, see Reduced execution time for findsdru.

Example: StatusOnly=false

Data Types: logical

Output Arguments

radios — Information about connected USRP devices

structure

Information about connected USRP devices, returned as a structure containing these fields.

Fields	Description
Platform	Model number of the USRP device
IPAddress	IP address of the USRP device
SerialNum	Serial number of the USRP device
Status	Status information of the USRP device

The Status field of this structure displays one of the messages described in this table.

Status Value	Definition
Success	USRP device is available.
No devices found	No USRP devices found.
Not compatible	Device with incompatible firmware. To communicate with this device, you must update the firmware to the version returned by the function getSDRuDriverVersion. You can update the firmware on your radio using the Radio Setup wizard.
Not responding	Device is not responding because of any of these reasons. The device is not attached to the host computer. No device with the specified IP address exists. If you saved a radio configuration when you set up your radio using the Radio Setup wizard, use the radioConfigurations function to find the IP address. The subnet address of the host computer does not match the subnet address of the device. The subnet address is the third field of the IP address. Verify that the subnet value of the host and radio are the same. For example, your NIC has an IP address of 192.168.10.1, and the IP address of the USRP radio is 192.168.20.2. The IP addresses differ in the third octet. The specified serial number is invalid.
Busy	Device is in use. The device is already owned by a block, a block dialog, or a System object™.
Unknown error	Unknown problem.

Version History

Introduced in R2012b

R2024a: Support for N3xx and X3xx series radio devices moved to Wireless Testbench

Support for NI™ USRP N3xx and X3xx series radio devices has moved from Communications Toolbox™ Support Package for USRP Radio to Wireless Testbench™ Support Package for NI USRP Radios.

R2022b: Reduced execution time for findsdru

The approximate execution time for the findsdru function with the StatusOnly argument specified as true to find a single radio and get its availability status is:

R2022a: 15.283560 s

R2022b: 2.240098 s

The code execution was timed on a Windows^® 10, Intel^® Xeon^® W-2133 CPU @ 3.60 GHz installed RAM 64.0 GB test system.

However, to check for the detailed status regarding firmware compatibility, no response from the device, and other UHD errors, set the value of StatusOnly to false. In this case, findsdru takes same time to execute as compared to the R2022a release.
