Uranus-c PRO PlayerOne cooling not working

[kris969]

Describe the bug
From Ekos, buttons to turn on and of camera cooling are greyed, so not usable.
When trying to set temperature at indi driver level, the set temperature command is sent to the driver, but no information are given back. With the actual behavior, the camera temperature is unknown

My setup
==Raspberry==

• Raspberry pi 4 - 4Mb
• Fresh install of Ubuntu 23.10 headless, generate from rpi-imager + sudo apt update && sudo apt full-upgrade
• a SSD directly connected to an USB3 port
• a reduce set of packages & including Indi driver from (ppa:mutlaqja/ppa) installed to fit my needs : gpsd, indi-bin, indi-gpsd, indi-playerone
  (version given at the end of this post)
• Raspi4 INDI Web Manager
• no other software installed on the Raspberry
• Raspberry is connected to my local network using a wired Ethernet connection

==Laptop==

• Ubuntu desktop 24.04
• Kstars/Ekos
• I use a connection to the Raspberry pi server threw the network using ports 7624 & 8624

To Reproduce
From the laptop, connection to playerone is ok:

General informations are:

From Ekos : impossible to activate the temperature cooling process : button is greyed:

On the laptop, from PlayerOne indi driver, i did the following steps:
-1- when setting temperature to -5°C, the following text is present in the log file on the raspberry.
-2- when setting Max dT to: 1 °C/mn and Threshold to: 0.2°C, the following text is added in the log file on the raspberry.
-3- when waiting with no action, the following lines are added in the log file on the raspberry.
Log:

On the latptop the indi driver interface is still showing a temperature of 0.00

It seems nothing is working about cooling...

Expected behavior
Just to have cooling working.
I haven't done yet all detailed tests for this indi driver, but it seems other functions are working.

Indi version used
indi-bin:

indi-playerone:

I started trying to locate where this issue could be coming from...

To do this:

• Firstly, I remove the indi-playerone ppa package using: sudo apt remove indi-playerone.
• I build the indi-playerone driver based on this 3rd Party Drivers repo, strictly following the recommendations
• To be sure, I did a reboot

My idea was to add some debug log, if needed, to try to understand the origin of this issue.

From my laptop, first of all, I checked the driver information at the indi driver interface. It appears that the version number is exactly the same but:

• the running driver is: "indi-playerone-ccd". Before it was "indi-playerone-single-ccd", as shown on the previous post.
• some extra information are present: SDK, Serial Number an Nickname.
  All theses information are in the following screenshot:
  

But a major difference is that: IT WORKS !!!
Maybe, the only remaining minor issues concern for "cooling power" and "refroidisseur". For me, if I am wrong let me know, these LED should be green.
Here is the view from the indi driver interface:

At the Ekos level, everything is OK, as you can see in the following screenshot:

So to conclude:

• From sources from https://github.com/indilib/indi-3rdparty: indi-playerone works well relative to cooling system (tested with Uranus-c PRO camera).
• There is something wrong for this package coming from the ppa.
• Maybe it doesn't seem normal to have the same version number for these two package...

I hope my modest contribution will help?
Have fun, looking at the sky ;)

Looks like many issues with packages in last release. The compiled version works OK but there is an issue with the Debian packages which is so far unknown. I could rebuild all packages but this could be disruptive at this stage. In 3 weeks we will rebuild all package for next INDI release.

[kris969]

Great decision!
I can continue so far with my workaround.
If you want I will be able to test the next release on my side to check if this issue will be effectively fixed.
Let me know ;)

Another point that could be useful to know: it's mandatory to install the libplayerone library.

Update...
On compiling the indi-playerone on a fresh Ubuntu 24.04 LTS on raspberry pi 4, when strictly following the howto as describe on 3rdparty repo, I got this:

on this Ubuntu version, the libPlayerOneCamera isn't available!

I was able to compile after havind done this:

• sudo add-apt-repository ppa:mutlaqja/ppa
• sudo apt update && sudo apt upgrade
• sudo apt remove libplayeronecamera2
• sudo apt install libplayerone

then:

Remark:
So far, I haven't done full test yet, it will be done later...

what's your point off view on this?

;)

@kris969 Thank you for reporting the issue.
I have same issue with my Poseidon-C Pro (cooled camera) on RasPi4 (Ubuntu 22.04).
Deb repository of indi v2.0.7 seems have some issues for cooling control.
I also build it from source code, it works well.
Although it doesn't solve the issue, but I have updated the SDK version to the latest v3.6.2.
Please check it on your side.

However, some model of PlayerOne cameras can't finish exposure on Ubuntu 24.04.
So please wait a little longer before using Ubuntu 24.04. (Ubuntu 22.04 and 23.10 has no issue as far as i know)
I don't have Uranus-C Pro, so I'd appreciate if you could help me test it.

It's a packaging issue that affected many drivers. Hopefully resolved by 2.0.8 release due June 1st.
