INDI monthly update. In addition to driver improvements, major code refactoring is in progress by @pawel-soja to modernize and improve INDI aging code.
K-70 in manual mode
PTP: I can change shutter speed, ISO, aperture etc. (perfect!)
MSC: I can change shutter speed and aperture (MSC states ISO cannot be changed on certain models).
But, the picture taken is not downloaded, EKOS states "downloading" forever.
I think you have to avoid ptp mode while using the K70.
I sold my K70 a few weeks ago, but the last time in used KStars downloading worked for me while in mft mode. Did you reset the driver after switching from ptp to mft?
