Summary

Add a BLE RSSI proximity detector example using aioble and steami_screen. Closes #9

Changes

  • Added BLE/BLE_RSSI_Proximity/RSSI_Proximity.py: a single-file example that runs on two STeaMi boards
  • Mode selection at startup via button UP held for 10 seconds:
    • BEACON mode: advertises continuously as STeaMi-BEACON
    • SCANNER mode: scans for the beacon and displays a proximity gauge
  • RSSI mapped to a 0-100% proximity gauge with dynamic color coding:
  • Display uses steami_screen widgets (gauge, value, subtitle, title)
  • Fully asynchronous design with uasyncio

Checklist

  • Tested on hardware (STM32WB55 / STeaMi board)
  • Beacon visible on nRF Connect
  • Proximity gauge reacts correctly to distance changes
  • Examples added (BLE/BLE_RSSI_Proximity/RSSI_Proximity.py)
  • Commit messages follow <scope>: <Description.> format
