Incomprehensible log a Bluetooth connection, any idea?

Hello.
There are smartphone and fitness bracelet. When trying to connect via the official application of the manufacturer of the bracelet, nothing happens: that is, the app hangs on "confirm the pairing on the bracelet", and on it no confirmation there. Notice that the device successfully connects to other BT devices, and it successfully connects to other smartphones. The smartphone runs on one of the official beta firmware for Android 7.1.1.

A catlog during the connection attempt. Here are excerpts from it (if necessary, attach the full log):

Please help me to understand why connection is not happening. It feels like a BT-firewall works :)
