Using the Pluto seems to be broken as of a recent commit, possibly this one b1e6daf

import adi
sdr = adi.Pluto('ip:192.168.2.1')

What versions of libiio, pylibiio, and Pluto firmware are you using?

Marc Lichtman · Answer 2 · Thu Sep 01 2022 23:12:08 GMT+0800 (China Standard Time)

libiio v0.23
libad9361-iio and pyadi-iio off master as of yesterday, not sure about the Pluto firmware sorry

Marc Lichtman · Answer 3 · Thu Sep 01 2022 23:12:54 GMT+0800 (China Standard Time)

and swapping to v0.0.10 of pyadi-iio fixed it (chose v0.0.10 arbitrarily, that wasn't the most recent version that fixed it)

The error is not repeatable in our test system.

Can you provide the output of this code:

import iio

ctx = iio.Context('ip:192.168.2.1')

for dev in ctx.devices:
	for chan in dev.channels:
		print('--------')
		print(chan.id, dir(chan))

It looks like you have very old python bindings. Can you create a virtualenv and just install pyadi-iio through pip so it grabs the correct bindings?

'''
virtualenv venv
source venv/bin/activate
pip install pyadi-iio==0.0.13
...
