Wireless connectivity

Fix the class in your product

The device honors control commands from any peer in radio range. As the maker, gate every state-changing characteristic behind an authenticated, bonded link on the device itself, and strip undocumented command paths from the release image.

Authenticate on the device, not the app. Reject writes to state-changing characteristics unless the link is encrypted, bonded, and authenticated.
Bond with a modern pairing method. Require LE Secure Connections and add a physical confirmation on a safety-critical device.
Fail to a safe state. On an unexpected or unauthenticated command, hold or revert rather than acting.
