Your code.py uses BLE only for advertising
The Glider app connects, and you can:
Create folders
Write files
After each file/folder operation (when running on battery, not USB), the device:
Performs: Run reason: supervisor.RunReason.AUTO_RELOAD
On reconnect (reopen app), the written data appears and is correct
