Overview
A mobile app was responsible for pairing devices and provisioning them for first use. Setup failures created delays in deployment and repeated support calls.
Challenge
The existing flow mixed BLE pairing, cloud registration, and user input in one fragile path. When any step failed, users had limited guidance and often restarted from scratch.
Approach
We broke setup into explicit stages, added clear error states, and introduced recovery actions for each failure mode.
Architecture
The new flow used staged state handling for pairing, registration, and validation, with idempotent provisioning requests and traceable setup logs.
Outcome
Operators could complete setup with fewer retries, and support teams had clearer context when troubleshooting failed installs.
Lessons
For mobile-plus-device products, setup flow quality is a core reliability concern, not an onboarding detail.
