Description

Write transport_ble.py (BLE GATT Nordic UART Service) and main.py (auto-detect transport, cooperative poll loop). BLE advertises as 'GaiaAR', chunks notifications to 20-byte MTU.

Acceptance Criteria

  • #1 NUS service with correct UUIDs registered
  • #2 IRQ handler queues to pending list, no heavy work in interrupt
  • #3 MTU chunking for notifications
  • #4 Auto-reconnect advertising on disconnect
  • #5 main.py soft-imports bluetooth for Pico/Pico W compat

Final Summary

transport_ble.py: GATT NUS with chunked notify, per-connection line buffers, auto-readvertise. main.py: soft BLE import, cooperative dual-transport loop, error-resilient.
