• Device Discovery: Auto-detect devices on local network via IP range scan and UDP broadcast; manual IP entry option.
• Compatibility Check: Read device model and current firmware version; match against allowed firmware images; block incompatible images.
• Firmware Repository: Centralized local/remote repository with version metadata, release notes, checksum (SHA256), and signature.
• Secure Transfer: Support HTTPS and SFTP; optional TLS client auth; verify firmware integrity with SHA256 and digital signature before flashing.
• Staged Rollout: Schedule updates, batch devices into groups, and perform rolling updates with configurable batch sizes and rollback windows.
• Resume & Retry: Resume interrupted transfers; configurable retry/backoff policy; detailed error codes.
• Pre/Post Scripts: Run pre-update checks (battery, free memory, running ops) and post-update validation (device reboot, service status).
• Rollback Mechanism: Automatic rollback to previous stable firmware on failed update or integrity check; retain last N images.
• Logging & Audit: Detailed update logs, per-device status, timestamps, operator ID; exportable CSV and syslog integration.
• Notifications: Webhooks, email, and SNMP traps for start/finish/fail events.
• Access Control: Role-based permissions for who can initiate updates, approve batches, and modify repository.
• Dry-Run & Simulation: Validate compatibility and simulate update without flashing for planning.
• CLI & API: REST API and CLI tool for automation and integration with management systems.
• Scheduling & Maintenance Mode: Schedule during low-usage windows; place devices into maintenance mode to prevent access disruption.
• Multi-Transport Support: USB, TCP/IP, and serial (RS-232/485) flashing for on-site and remote updates.
• Device Health Checks: Pre-update diagnostics and health dashboard showing readiness.
• Localization & Help: Contextual guidance, rollback instructions, and localized UI strings.
