Practical insights for connected products, software and IoT decisions.
Android BLE scans can miss devices because of permissions, advertising behavior, filters, or scan lifecycle issues. Follow a structured workflow to identify where discovery fails.
A device protocol specification needs more than command codes. Use this practical checklist to document message formats, device states, acknowledgements, security, and compatibility before integration begins.
A successful MQTT publish does not prove that a device completed a command. Learn how to track acceptance, execution, and results with command IDs, explicit acknowledgements, and safe retry rules.
A reliable BLE connection is not a single API call. It is a controlled workflow that detects failures, preserves device identity, retries with backoff, restores GATT services and notifications, and returns the application to a verified ready state.
A practical checklist for finding the connection-state problems that often appear outside a successful first pairing.
How to assess the build, device workflow and hidden dependencies before committing to a rewrite.
