Where can I download the 2016 SDK file?

Hi, the SDK I’m using now is the 2016 version, but the previous one was made by my former colleague.I want to download the 2016 SDK file and compare it with the latest SDK in 2019, so that I can upgrade the current APP.

Because I was faced with a problem that the SDK in 2016 could not connect to the hardware of MARKII, so I had to upgrade the SDK part. However, I upgraded the SDK to the latest SDK in 2019, but it still could not be connected, so I wanted to compare the differences between the two SDKS.

At the same time, I want to get some Suggestions from you. What should I modify to upgrade the 2016 SDk to the 2019 SDk?This problem has been bothering me for a long time.

Thanks for your reply

I have got it from the sdk downlaod history.
Thanks for the forums.
