Companion ring pairing

Purpose

Demonstrate scanning, attaching, and surfacing headset companion ring telemetry on the phone.

Entry points

Phone settings hierarchy:

• SettingActivity → DeviceLinerActivity

Sample Activity:

• com.rokid.phone.ui.DeviceLinerActivity

Platform

• Phone

Main files

• DeviceLinerActivity.kt
• DeviceLinkerAdapter.kt

Flow

1. Register IBTRingClientListener.
2. Call startScan() with curated filters for supported ring SKUs.
3. Populate the Recycler list with discoveries.
4. On tap, call connectToServer() and await callbacks updating UI badges.

Highlighted APIs

• Ring-aware discovery
• Dedicated connect shim
• Result callbacks powering UI badges

Caveats

• Filters hard-code friendly names (D01, D06) — adjust before retail.
• UI surfaces both connected/disconnected states inline.
• Flipping “connection enabled” toggle stops scans and forcibly disconnects the active ring session.
