This is my envirorment

Android Samsung Galaxy Note 4 (Android 6.0.1)

Samsung Gear S3 (Tizen 3.0.0.1)

Using “Hello Message” example, I did data receiving to get heart rate.

Data sending from Android is OK, but I can receive data from Tizen device.

So, I launched “Hello Message” app. It also didn’t work.

I think before Tizen 2.3.1 It worked but not now.

What should I do? or Is there anyway to downgrade Tizen 3.0.1 to 2.3.1?
