Hi, I have run the Downlink Receiver code with simulations (generated from the 5G Waveform Generator in MATLAB) and there are no issues there, however, when I try to tun the same code through collected raw data, it has never worked before (it says PSS not found). The collected data is confirmed to contain relevant information by other members of my research team, so the problem does not lie with the data itself. Has anyone faced a similar issue?
Do note that both the SSB detection code and the cell search code do not work.
Thank you so much for your help!

Hello community,
I am modelling a liquid cooling network which i will parameterize based on a real liquid cooling network that i built.
It consistis of a pump, radiator, reservoir and a cooler element beside the tubing and all additional sensors.
In that particular scenario, the pump is turned on after 10 minutes and reaches it full flowrate after 10 seconds, from there it is constantly working till stop.

The cooler is modelled as a tube element hooked up to a thermal network which is applying 10W of power. The simple tubes before and after should modell the natural convection that i see in the real measurements while powering the heater and keeping the pump turned off.

If the pump is turned on at 600s, we can see a temperatue increase in the sensor located after the cooler which i cannot see in the real measurements and rather looks like the decreasing cooler surface temperature.
I would like to understand how this behavior is created and if possible how to avoid it. I can imagine that at the port of the temperature sensor, after the liquid was heated for that time, that the mass of the liquid inside the cooler is virtually passing the temperature sensor and it taking some time to cool down to average coolant temperature. But as a novice in Simscape Modelling I am having a hard time understanding the mechanisms behind that.
I greatly appreciate any suggestion and explanations from you, looking forward to it. Thanks much!Hello community,

Hi all,

We have a project where we communicate with a device using gRPC. On the computer, we run Python in a virtual enviornment. We load that environment in matlab using pyenv. We use MATLAB 2023b (23.2.0.2599560 (R2023b) Update 8) and Python 3.10.11.
Connecting with the device and querying some device information works in both, Python and MATLAB. However, since 2-3 months, we are unable to access members of protobuf messages. Below is an example of the code we execute in Python and the equivalent code executed in MATLAB:
Python:
% C:workdatakingfisher-py.venvScriptspython.exe "…"
import kingfisher_py.lib as kgfLib
scn = kgfLib.device.Scanner(‘10.10.1.1’, ‘8081’)
device_info = scn.device_info.get_info()
device_info.sw_rev
items {
key: "mcu"
value: "v1.0.1"
}
items {
key: "kingfisher"
value: "5.2.0-cam-cal-third-party-rc.1-5-gd6f7161"
}
% response continues…

MATLAB:
>> kgfLib = py.importlib.import_module(‘kingfisher_py.lib’);
>> scn = kgfLib.device.Scanner(‘10.10.1.1’, ‘8081’);
>> deviceInfo = scn.device_info.get_info();
>> deviceInfo.HasField(‘sw_rev’)

ans =

logical

1

>> deviceInfo.sw_rev
Unrecognized method, property, or field ‘sw_rev’ for class ‘py.kf.api.messages.system_pb2.GetDeviceInfoResponse’.

>> deviceInfo

deviceInfo =

Python GetDeviceInfoResponse with properties:

DESCRIPTOR: [1×1 py.google._upb._message.Descriptor]

manufact_rev {
device_name: "BLK360-2060047"
serial_number: "2060047"
}
sw_rev {
items {

value: "v1.0.1"
}
items {
key: "kingfisher"
value: "5.2.0-cam-cal-third-party-rc.1-5-gd6f7161"
}
% response continues…

Note that the same virtual environment is active. MATLAB even says that the field sw_rev exists, but still cannot access it. Also, we checked different versions and combinations of MATLAB and Python. Specifically:
Matlab 9.10.0.2198249 (R2021a) Update 8 + Python 3.8.10
Matlab 9.13.0.2193358 (R2022b) Update 5 + Python 3.8.10
Matlab 9.13.0.2193358 (R2022b) Update 5 + Python 3.10.11
Matlab 23.2.0.2599560 (R2023b) Update 8 + Python 3.10.11
The behaviour is the same with all versions. As the whole communication with the device is set up using protobuf, there is not much we can do with the device at this point as we run into this problem all accorss our MATLAB code base.

Is this a known issue, e.g. with a newer protobuf version? As mentioned, we did not have any issues like this until 2-3 months ago.

Hope to get some help or at least an explanation. Thank you :-)Hi all,
