Something isn't working

Looks like it's triggered when the subframe is set? If you do this manually in the driver, is this behavior triggered? |
|
I can't say anything about that, because I haven't done any research on the source code yet. Maybe the problem is that #654 is replacing the size of the ROI with the size actually set by the SVBONY SDK, as opposed to the size of the ROI expected by the Focuser module. |

Log when reproducing the Issue. |
|
Maybe while exposure is in progress, you cannot inquire of other parameters and must wait until exposure is finished? Not sure, just a guess. |
|
This does not seem to be the case. |
|
I have created the test code linked below to reproduce this issue. After making it, run the following. The code repeats 12 times calling SVBSetROIFormat, exposing with SVB_MODE_TRIG_SOFT and SVBGetVideoData. If the ROI is not changed, this problem will not occur. I have not checked for anomalies in cooling related functions, but the error with SVBGetVideoData also occurs with the INDI SVBOY CCD driver. I am contacting SVBONY about this issue. |

Hi @knro SVBONY seems to be aware that the camera cannot send data regarding the small ROI. |

@jctk Excellent, thank you for the update. We will await their communication. |

Hi @knro |

Details are unknown at this time.
I guess this Issue is affected by fix #654.
I found this issue while using "Astroberry Focuser", but it also occurs in "Focuser Simulator".
It seems to affect Focuser in general.
Describe the bug
When Auto Focus is executed with the cooler on in the SV405CC, the following error repeatedly occurs after "Subframe set" after a short period of time, and the camera cannot take pictures.
The error message remains after Auto Focus is stopped.
To Reproduce
Telescope Simulator,Focuser Simulator and SVBONY SV305 drivers. <-- no need Telescope Simulator to reproduce.Cooler on.<- Reproduce even with the cooler off.If no error occurs, stop Autofocus and repeat the operation from 3.
Expected behavior
No error occurs.
