I need a mobile app to manage two screenless BLE peripherals simultaneously. Since the devices have no displays, the app must handle the entire pairing and control flow. Core Tasks: - Implement a "Scan & Filter" UI that identifies the correct two devices (likely via RSSI/proximity). - Establish and maintain two concurrent, stable GATT connections. - Develop a robust reconnection logic for when devices go out of range. -Roadmap: Phase 2 will involve adding Auracast (LE Audio) support, so an understanding of Bluetooth 5.2+ architecture is required. Technical Requirements: - Experience with Multi-link BLE (connecting to multiple devices at once). - Proficiency in Flutter or React Native (for cross-platform) or Swift/Kotlin. - Familiarity with "Just Works" pairing and GATT state machines. Deliverable: A functional demo app that keeps two generic BLE simulators or off-the-shelf sensors connected for 30+ minutes without dropping.
