pyadi-iio problem - ubuntu - TimeoutError: [Errno 110] Connection timed out

TimeoutError: [Errno 110] Connection timed out

Hi, I am having this situation with one specific computer. All similar computers work fine but not this one. All use ubuntu 22.04.1

After installing all libraries, in all cases with the same procedure, in the failing computer I have the following problem. I tried different buffers sizes however none worked. The failed computer is also using a different pluto unit, however it is also rev C as in the working computer.

rfuser@rfhost:~$ python3

Python 3.10.6 (main, Nov 14 2022, 16:10:14) [GCC 11.3.0] on linux

Type "help", "copyright", "credits" or "license" for more information.

>>> import adi

>>> sdr = adi.Pluto('ip:pluto.local')

>>> sdr.sample_rate = int(1e6)

>>> sdr.rx_lo = int(400e6)

>>> sdr.rx_buffer_size = int(1e6)

>>> iq = sdr.rx()

Traceback (most recent call last):
