ota-server/backend/app/routers/devices.py:8

• The calculate_file_md5 import is not used in this file and should be removed to keep imports clean.

from app.utils import (get_devices, get_device, update_device, delete_device, validate_mac_address, format_mac_address, calculate_file_md5)

ota-server/backend/app/utils.py:21

• The new utility functions (e.g., generate_auth_token, compare_versions, calculate_file_md5) lack accompanying unit tests. Consider adding test cases to cover edge cases and ensure correct behavior.

ota-server/backend/app/auth.py:43

• The verify_device_auth dependency declares a mac_address parameter but never extracts it from the request (e.g., via Query). As written, mac_address is always None and authentication will always fail. Update the signature to something like:

async def verify_device_auth(
    auth_token: str = Depends(DEVICE_AUTH_HEADER),
    mac_address: str = Query(..., alias="mac")
) -> bool:

async def verify_device_auth(

• The .env example includes OTA_SERVER_UI_PORT, but the Settings class in config.py does not define this variable. Either remove it from the docs or add it to your settings model.

OTA_SERVER_UI_PORT=80
