Yesterday, I downloaded a Beta released 2.1.3!!!!!! Bug fixes and updates.......... This is from the Android site gpyer.com.
Two days ago, I reinstalled the 2.1 10.74fw app on my S4 tab. With that running, all my issues with 2.1.2 were gone. Captured 50 exp of 2 min subs of M81. So, releived that it wasn't a hardware PS failure as I had thought. Also, processed those images to a finished image. With that indentical setup and the 2.1.3 installed on my AIR Pro, I started a new imaging session. All hardware recognized, AF completed, PA completed, Go-to M81 completed and centered, Auto guided calibrated and an Auto run of 30 images for 1 hour completed. NO ISSUES............. Features that I use that had been updated in 2.1.2 now worked. NO "exposure failures". One think, I could NOT test was the changes to the 2600 MC Pro camera. That camera is being returned to ZWO for 12v port intermittentcy.
Clear skies to the rest of society and try that release if were having issues with 2.1.2. ONLY if, you have a way back to an a working AIR.... As of this morning, it has NOT been a full release. IMHO
