Hi, I got new GEM45 last week with firmware(210105). I wonder which iOptron I should select. If I select ioptronv3 driver, GEM45 is able to slew. If I select GEM45 indi driver, it get error
"[ERROR] Serial read error: Timeout error. "

The full name should be v20210105 in www.ioptron.com/Articles.asp?ID=318, but the download link is invalid. My GEM45 just comes with firmware(v20210105).
Hi, Rishigarrod, please let me know the difference if you upgrade to new firmware.

iOptron releases new GEM45 now. Previous GEM45 separates iPolar & USB control into two cable, no usb hub. New GEM45 only has one USB line, which contain iPloar, mount control(FDTI USB serial), USB2.0 hub. I guess it will be something different, especially in power manager. More, new firmware(210105) may also make different communication. We are using Ubuntu 20.04 (aarch64) in SoC Khadas VIM3.
