Pluto Tx infinite loop

[drom]

Installed latest: SDRangel 7.13.0 Qt 5.15.9 64b x86_64 openSUSE Tumbleweed I can add Pluto RX channel fine. But after adding Pluto TX, SDRangel goes into infinite loop with this message repeated again and again:

Previous version (7.11?) worked fine

Accidentally updated SDRangel to version 7.13.0-1.8 and got a problem. TRANSMISSION window won't load, persistent message, here's a snippet:

How to return to the old version?

[mattmelling]

+1 I am seeing this as well with a Pluto Rev C.

[eu2aa]

I had to switch to the old version 7.6.3-lp153.1.3.x86_64

[eu2aa]

Version 7.13.0-1.9 has the same problem

[srcejon]

I had to switch to the old version 7.6.3-lp153.1.3.x86_64

That suggests the problem was introduced in this patch:

https://github.com/f4exb/sdrangel/commit/94a465b2108639ad70f685fd0c6afcb6642d0283 (input)

https://github.com/f4exb/sdrangel/commit/79b174bf360d64e50f5fdb943a90695c096a679e (output)

Possibly one of the settings keys is wrong / missing.

(I don't have a Pluto so can't debug it.)

[eu2aa]

interesting idea

[mattmelling]

Possibly one of the settings keys is wrong / missing.

Is this settings as in user configuration? Can it be cleared by removing some config file?

Can also confirm that 7.6.0 works. while 7.9.0 does not which also points to that commit.

No. I suspect it's a problem in the code.

[github-actions[bot]]

This issue is going to be closed due to inactivity

[drom]

Anybody having similar issue?

[eu2aa]

too bad there won't be a FIX for TUMBLEWEED. I'm still working with the surrogate version 7.6.3-lp153.1.3.x86_64. Transceiver mode has fallen. I'll have to go somewhere... it's a pity, that did not wait for the solution of the problem. Good luck everyone!

[srcejon]

One possible problem in plutosdroutput.cpp. We have:

else if (DevicePlutoSDRShared::MsgCrossReportToBuddy::match(message)) // message from buddy
{
    DevicePlutoSDRShared::MsgCrossReportToBuddy& conf = (DevicePlutoSDRShared::MsgCrossReportToBuddy&) message;
    m_settings.m_devSampleRate = conf.getDevSampleRate();
    m_settings.m_lpfFIRlog2Interp = conf.getLpfFiRlog2IntDec();
    m_settings.m_lpfFIRBW = conf.getLpfFirbw();
    m_settings.m_LOppmTenths = conf.getLoPPMTenths();
    PlutoSDROutputSettings newSettings = m_settings;
    newSettings.m_lpfFIREnable = conf.isLpfFirEnable();

    applySettings(newSettings, QList<QString>{"lpfFIREnable"});

    return true;
}

This call to applySettings appears to be missing some settings keys. Just like in the input module, it should possibly be:

    applySettings(newSettings, QList<QString>{"devSampleRate", "lpfFIRlogInterp", "lpfFIRBW", "LOppmTenths", "lpfFIREnable"});

[f4exb]

Alas this does not fix the issue

[f4exb]

The loop appears because the input wants to send some changes to the output and then the output to the input etc... You can figure out this only if you have debug messages:

This design prior to the implementation of "MIMO" devices is problematic because it tries to fit two plugins for the same physical device.

In the BladeRF2 plugins equivalent pair the applySettings method of the m_settings is called not the applySettings method of itself.

[eu2aa]

only 7.13.0 on https://software.opensuse.org/package/sdrangel, sorry

[f4exb]

We are not maintaining OpenSUSE packages sorry. We cannot deal with every distribution in the world. There are packages for Debian/Ubuntu, Windows, Mac and Android...

In Open Source there is "source" so you know what you should be dealing with.

[eu2aa]

thank, Edouard!
