findsdr

Status of software-defined radios (SDRs) connected to host computer

Since R2026a

Syntax

radios = findsdr()

radios = findsdr(SDRType=Type)

radios = findsdr(StatusType=Status)

radios = findsdr(SDRType=Type,Address=SDRAddress)

Description

Add-On Required: This feature requires one of these add-ons.

• Communications Toolbox Support Package for Analog Devices ADALM-PLUTO Radio
• Communications Toolbox Support Package for RTL-SDR Radio
• Communications Toolbox Support Package for USRP Radio

radios = findsdr() returns a table that contains the radio name, radio type, and IP address or serial number of every SDR that is connected to the host computer.

radios = findsdr(SDRType=Type) returns a table that contains the model number, IP address or serial number, and status of every SDR of the type specified by Type that is connected to the host computer.

radios = findsdr(StatusType=Status) returns a table that contains the model number, IP address or serial number, and status of every SDR of the status specified by Status that is connected to the host computer.

radios = findsdr(SDRType=Type,Address=SDRAddress) returns a table that contains the model number, IP address or serial number, and status of every SDR of the IP address or serial number specified by SDRAddress that is connected to the host computer.

Examples

Find Software-defined Radios Connected to Host Computer

Use the findsdr function to find the SDRs connected to the host computer.

radios = findsdr()

Set the SDRType to the desired SDR to get the information about of a specific SDR type connected to the host computer. For example, to get the list of all Pluto radios connected to the host computer, set SDRType to PLUTO.

radios = findsdr(SDRType="PLUTO")

Set the Address to desired IP address or serial number to get the status of an SDR with specific IP address or serial number.

radios = findsdr(SDRType="USRP", Address='192.168.10.2')

Set the StatusType to TxRxAvailable to get the status of transmitter or receiver on SDRs.

radios = findsdr(StatusType='TxRxAvailable')

Input Arguments

SDRType — Type of SDR

"All" (default) | "PLUTO" | "RTLSDR" | "USRP"

Type of SDR, specified as a string scalar or character vector. Use this option to get the status of a specific type of SDR connected to the host computer.

Example: "USRP"

Data Types: char | string

StatusType — Status type of SDR

"SDRList (default) | "TxAvailable" | "RxAvailable" | "TxRxAvailable" | "RxTxAvailable" | "DetailedStatus"

Status type of the SDR, specified as a string scalar or character vector. Set StatusType to one of these values:

• "SDRList"— Lists SDRs connected to the host computer with the corresponding SDR name, SDR type, and IP address or serial number

• "TxAvailable"— Lists available transmitter on the SDRs connected to the host computer with the corresponding SDR name, SDR type, and IP address or serial number.

• "RxAvailable"— Lists available receiver on the SDRs connected to the host computer with the corresponding SDR name, SDR type, and IP address or serial number.

• "TxRxAvailable"— Lists both available transmitter and receiver on the SDRs connected to the host computer with the corresponding SDR name, SDR type, and IP address or serial number.

• "RxTxAvailable"— Lists both available transmitter and receiver on the SDRs connected to the host computer with the corresponding SDR name, SDR type, and IP address or serial number.

• "DetailedStatus"— Lists the detailed status of SDRs connected to the host computer with the corresponding SDR name, SDR type, IP address or serial number, and transmitter or receiver availability.

Data Types: char | string

Address — IP address or serial number of SDR

string scalar or character vector

IP address or serial number of the SDR, specified as a string scalar or character vector.

Data Types: char | string

Output Arguments

radios — Information about connected SDRs

table

Information about connected SDRs, returned as a table. See the table for variable descriptions.
