CM-530을 사용 중이고 블루투스를 통해 안드로이드에 통신시키고 싶습니다.
BT-410을 사용해야 할 것으로 보이는데 사용하면 안드로이드와 통신이 가능한지, 어떻게 해야 통신이 되는지를 알고 싶습니다.
Back in 2017, I was successful in using the OLLOBOT SDK between an Android phone (using Android Studio) and CM-50, CM-150, and OpenCM-904. But I did not try it with a CM-530, because the CM-530 can only deal with DXL Packet Protocol 1, and the OLLOBOT SDK only deals with DXL Packet Protocol 2. So, you’ll need to make a decision about keeping using CM-530 for your Android project.
Please see these YouTube links for the videos involved - you’ll have to watch them straight from YouTube.
There is a GITHUB for the OLLOBOT SDK at
ROBOTIS also has several special applications (APK files) using the OLLOBOT SDK at this link

There is an OLLOBOT SDK tutorial at
If you are affiliated with a university, you may be able to use the university’s library via Springer-Link to have a look at Chapter 12 of this book with free access.

This Springer Extras link has all the example codes for my 2017 book:
There should be several ZIP files with the name “OLLOBOT….zip” for the Android Studio files that were used back in 2017.
It has been a very long time ago, so I am not that conversant with Android Studio anymore, so this is the extent of my knowledge for this topic. 
.
Good Luck with your project.
P.S. Back in 2017, the CM-550 did not exist! So you want to take on the challenge to be the first user to interface the OLLOBOT SDK with the CM-550?
