Error using coder.internal.errorIf (line 8) - Unable to find radio with IP address...

Hi,

I was running "sdruLTE2x2SIB1Tx" example and output was as the following: radio = comm.SDRuTransmitter with properties:

                 Platform: 'X310'
                IPAddress: '192.168.12.2'
           ChannelMapping: [1 2]
          CenterFrequency: 900000000
    LocalOscillatorOffset: 0
                     Gain: 0
                PPSSource: 'Internal'
              ClockSource: 'Internal'

      InterpolationFactor: 96
        TransportDataType: 'int16'
          EnableBurstMode: false

Starting transmission Please run sdruLTE2x2SIB1Rx.m in a new MATLAB session Error using coder.internal.errorIf (line 8) An error occurred: Unable to find radio with IP address 192.168.12.2. Attach a device with this IP address, or continue working in offline mode.

FYI: >> findsdru ('192.168.12.2')

As you can see here the radio was instantiated and it is connected and on top of that executing probesdru ('192.168.12.2') ans = -- X300 initialization sequence... -- Determining maximum frame size... 1472 bytes. -- Setup basic communication... -- Loading values from EEPROM... -- Setup RF frontend clocking... -- Radio 1x clock:200 -- Initialize Radio0 control... -- Creating WSA UDP transport for 192.168.12.2:49153 -- Performing register loopback test... pass -- Initialize Radio1 control... -- Creating WSA UDP transport for 192.168.12.2:49153 -- Performing register loopback test... pass ___________________________________________________ / | Device: X-Series Device | ___________________________________________________ | / | | Mboard: X310 | | revision: 6 | | product: 30508 | | mac-addr0: 00:80:2f:0a:f9:e4 | | mac-addr1: 00:80:2f:0a:f9:e5 | | gateway: 192.168.10.1 | | ip-addr0: 192.168.12.2 | | subnet0: 255.255.255.0 | | ip-addr1: 192.168.20.2 | | subnet1: 255.255.255.0 | | ip-addr2: 192.168.30.2 | | subnet2: 255.255.255.0 | | ip-addr3: 192.168.122.2 | | subnet3: 255.255.255.0 | | serial: F58DC9 | | FW Version: 4.0 | | FPGA Version: 19.0 | | | | Time sources: internal, external, gpsdo | | Clock sources: internal, external, gpsdo | | Sensors: ref_locked ....

So that means Matlab is able to communicate with the X310 connected, So I am not able to understand why I am getting the: "Unable to find radio with IP address 192.168.12.2"

My system is a Windows Server 2012 R2, Matlab 2016b and matlabshared.supportpkg.getInstalled gives Name Version Base Product --------------------------------------------------------------- ------- ----------------------------- Communications System Toolbox Support Package for USRP® Radio 16.2.2 Communications System Toolbox

Hi,

I have same problem. I tested it on two computers (same Win 10, Matlab 2019a, UHD_3.13.1.0, USRP X310 converted from NI 2944R) on one local network.

On PC A it works fine (it takes cca 15 seconds to download/RX few IQ samples and first two buffers are empty).

But on PC B it not work at all (both TX and RX). With this error mesagges:

>> An error occurred: Unable to find radio with IP address 192.168.2.62.

Attach a device with this IP address, or continue working in offline

mode.

>> a = findsdru('192.168.2.62')

Checking radio connections...

a =

Platform: '' [on PC A it is fill by platform name]

IPAddress: '192.168.2.62'

SerialNum: '' [on PC A it is fill by ser number]

Status: 'Success'

Does anybody have suggestion where could be problem?

Firewall?
