can not connect my gear s3

[bade18]

Please Help.
I found a great Note 8 Port on SAMSUNGVN.com
https://samsungvn.com/diendan/thread...os-only.34187
it is great...
but i have a big problem.
i can not connect my gear s3.. it connects to phone via bluetooth but always remain on pairing screen.
i never had such a problem before with any rom i used.
i have contacted the developer , but he can not help me because he has no gear s3.
If anyone had sane issue before or know what to port to rom so as to connect with the watch it would be great help.
PLEASE HELP.
Thank you
