probing error?

[EastEriq]

What is this error? Now the focuser object was correctly created, the configuration points at the right place, and the .probe method is api decorated and returns a boolean. (happens for both focusers, so it is common code)

Ditto for mount: the log says

Since I completed the probe methods for camera, focuser and mount, the webby is not affective on them anymore - I get like

Response body
{
  "Error": "LIPP connection to 'lipp-driver-focuser-1' refused"
}

I imagine this is due to the bailouts. Hm, maybe something wrong with my understanding that .probe should return a boolean? Where is that written?

Fixed with commit #8d7178d

It seems that I still get it:

Same was for camera1, which lead to a segfault, as per https://github.com/EastEriq/LAST_QHYccd/issues/1, it seems a bit random when and when not (typical hint of a race), but that is still another story.

Reopening....

Fixed with commit #8d7178d

I think that you tackled the second line of the error stack, not the one which it calls (line45 of obs.api.POSIXsocket.pyPOSIXsocket/sendto) and generates the error

[EastEriq]

Might it be that a definition of sendto, on the lines of that of recv, is missing in LAST_Api/+obs/+api/+POSIXsocket/pyPOSIXsocket.py?

[blumzi]

I added the sendto but I can't test it on my machine. Please try it on the last11 machines. I'm not sure this is the fix, but let's see.

[EastEriq]

As of today I don't get these errors anymore, so I think the issue can be closed.
