Issue with iio attribute updater #7426

Open paolocos opened 2 months ago

paolocos commented 2 months ago

What happened?

simple flowgraph with QT range (for frequency), iio_attribute_updater, iio_attribute_sink. At start seems to work but as soon as I modify the slider to change the frequency the following error occurs and gnu radio crash.

I have almost the same problem when I change gain of plutoSDR sink (via QT GUI Range), I come across with the problem below:

Traceback (most recent call last):

Myself and another user seem to be having this issue also as per: https://ez.analog.com/linux-software-drivers/f/q-a/558818/adrv9009-rx-to-tx/460989

This appears to have been caused by an issue with the Python bindings in GNU Radio, which appears to have been fixed by https://github.com/gnuradio/gnuradio/commit/70fa7e352d54a4d1afb1dde987d373e391902eaf under https://github.com/gnuradio/gnuradio/pull/7309. The relevant file is gr-iio/python/iio/bindings/attr_updater_python.cc where the binding set_params should be set_value.

This issue is therefore a duplicate of #7309.
