Hi,
good point.
I did a first check ...update some methods ...
The Devices list is correct but the device.getProperties() seems not working properly, data look corrupted ....

Still digging.

This is some test code I have in indi-allsky which properly returns data...
    def getDeviceProperties(self, device):
        properties = dict()
 
        for p in device.getProperties():
            name = p.getName()
            properties[name] = dict()
 
            if p.getType() == PyIndi.INDI_TEXT:
                for t in p.getText():
                    properties[name][t.getName()] = t.getText()
            elif p.getType() == PyIndi.INDI_NUMBER:
                for t in p.getNumber():
                    properties[name][t.getName()] = t.getValue()
            elif p.getType() == PyIndi.INDI_SWITCH:
                for t in p.getSwitch():
                    properties[name][t.getName()] = self.__state_to_str_s[t.getState()]
            elif p.getType() == PyIndi.INDI_LIGHT:
                for t in p.getLight():
                    properties[name][t.getName()] = self.__state_to_str_p[t.getState()]
            elif p.getType() == PyIndi.INDI_BLOB:
                pass
                #for t in p.getBLOB():
                #    logger.info("       %s(%s) = %d bytes", t.name, t.label, t.size)
 
        logger.warning('%s', pformat(properties))
 
        return properties

Hi,
thanks for the help.
I used your function to extract properties... but.. it's crashing still on <code>device.getProperties()</code> ...but it evolved ...now it's a segmentation fault...

Is it possible that the Raspberry Pi3+ don't have enough memory ...

for information i extracted using commands (hecate is my remote server executing indiserver) :
telnet hecate 7624
then
<getProperties version="1.7"/>

it looks good...

I will try to use a debugger to find root cause of this segfault...

Ok i give up. Anyway .... I share all information.

Aaron i tried, your code, but the problem is the same about getProperties() function.

I use pdb to debug a little bit more....not too much more information :
indi-mqtt: AD - getDeviceProperties

(you recognize segmentation fault, in french)

line 1279 of PyIndi is ...
def getProperties(self, *args):

I also tried the example here in Getting Started (github.com/indilib/pyindi-client)
I use indiserver with simulators (telescope, ccd, guide, ...) . And it works ... but don't likes the telescope simultator property, next after GUIDE_RATE...
I don't understand why.

Well, I did strip out a comment from my code...
### Causing a segfault as of 8/25/22


I do not recall which version of indi I was running, probably 1.9.8. What version of INDI do have have installed?

My guess is you are using Astroberry. Unfortunately, Astroberry is not currently maintained and is stuck on a very old release of INDI.

I pulled down indi-mqtt and tested it on INDI 2.0.4 and it seemed to run fine. The code is in need of some maintenance and updates, though. I may consider trying to maintain my own fork.

Hi,
compilation 2.0.4 is not working :-/
So i gave up the installation on rapsbian...and used another computer under Ubuntu...and indi-mqtt works perfectly ...
So the problem was the version of indilib...
Thanks for your help.
