Android companion app for configuring UWB tags via BLE GATT.

Changes

  • android/src/main/kotlin/com/saltylab/uwbtag/UwbTagBleActivity.kt — main Activity with BLE scan, GATT connection, config read/write
  • android/src/main/res/layout/activity_uwb_tag_ble.xml — Material Design UI: scan list + config form
  • android/src/main/res/layout/item_ble_device.xml — scan result row
  • android/src/main/AndroidManifest.xml — BLE permissions (API 26+/31+)
  • android/build.gradle — Kotlin/Android app build config

Features

  • Scans for devices whose name matches UWB_TAG_*
  • Connects to GATT service 12345678-1234-5678-1234-56789abcdef0
  • Config char …def1: read/write JSON (sleep_timeout_s, display_brightness, tag_name, uwb_channel, ranging_interval_ms, battery_report)
  • Status notifications …def2 and battery notifications …def3 shown live
  • Runtime BLE permissions for API <31 and API 31+
  • Standard Android BLE APIs only

- UwbTagBleActivity: BLE scan filtered to 'UWB_TAG_XXXX' device names
- Connects to GATT service 12345678-1234-5678-1234-56789abcdef0
- Read/write JSON config char: sleep_timeout_s, display_brightness,
  tag_name, uwb_channel, ranging_interval_ms, battery_report
- Subscribes to status + battery notification characteristics
- Material Design UI with scan list, config form, and live status
- Runtime BLE permission handling for API 26+ / API 31+
