OTA Updates & Diagnostics
Reliable over-the-air updates for automotive deployments
AutoPi OTA provides a secure delivery pipeline for firmware, OS components, and application-level updates across distributed automotive fleets. Each update is packaged with manifest metadata, checksummed, and verified on-device before install. The system supports full-image upgrades, delta patching, and component-level updates, reducing bandwidth consumption while maintaining field reliability.
Designed for real-world telematics environments, the device exposes detailed diagnostics covering CPU load, memory pressure, service health, modem state, CAN interface status, and filesystem integrity. Watchdogs monitor critical services, and failures automatically trigger recovery routines or rollback to a previously known-good state. Engineers can remotely inspect logs, trigger controlled reboots, restart services, and gather runtime telemetry to accelerate troubleshooting.
OTA orchestration is handled through AutoPi Cloud, where staged rollouts, per-device targeting, and version pinning keep deployments predictable. All communication uses TLS with device certificates, and update transactions are fully logged with timestamps, VIN mappings, and operator identity for traceability. Integrate with existing workflows using REST, webhooks, and automation hooks to align updates with CI/CD pipelines, compliance requirements, or internal release processes.

Feature Highlights
Global Automotive OTA:
Diagnose, Orchestrate, Update
Plan and execute OTA campaigns across mixed fleets from a single interface. Target specific devices or segments, monitor rollout status in real time, and use built-in diagnostics to verify that software, configuration, and connectivity remain healthy in the field.
Streamlined OTA & Diagnostics Control
Use AutoPi Cloud to define update campaigns, select device cohorts, and track progress per unit. Combine software rollout with live health metrics from each device so you see immediately where an update succeeded, failed, or requires manual follow-up.
Roll out updates in stages by customer, region, vehicle type, or software version. Pin specific devices to known-good builds, monitor install status, and use automatic rollback to keep critical vehicles on stable software at all times.
Deploy applications and scripts that send controlled CAN, CAN-FD, or J1939 messages from the AutoPi device to supported ECUs. Use this to adjust parameters, trigger diagnostics, or interact with body-builder equipment without physical access to the vehicle.
Inspect logs, service status, CPU and memory usage, modem connectivity, and CAN bus health from the dashboard. Trigger remote reboots, service restarts, or additional data capture when something looks wrong, shortening time-to-diagnosis.
All OTA traffic is transported over TLS with device certificates, and update bundles are checksummed and verified on-device before install. Every update attempt is logged with timestamps, device identifiers, and outcome for full traceability and compliance reporting.
Export update status, error codes, and device health metrics through APIs or webhooks to your own monitoring, analytics, or BI tools. Correlate software versions with faults, downtime, and performance to guide future releases.
Secure OTA Delivery
Deliver firmware, OS patches, and software modules through authenticated OTA packages with checksum verification, rollback protection, and device-level certificate validation to ensure safe and predictable updates.
Diagnostics & Health Monitoring
Monitor modem connectivity, CAN bus health, service uptime, CPU/memory usage, and system logs. Trigger remote restarts or collect debug snapshots to resolve issues long before vehicles return to the workshop.
Encrypted Data & Update Integrity
All OTA communication runs over TLS with unique device certificates. Packages are hashed and verified on-device, and update events are logged with timestamps and identifiers for full auditability.
Remote Control & Fleet Management
Roll out updates, restart services, reboot devices, or push configuration changes remotely. Apply actions to individual units or entire fleets through templated rollout flows and API-driven automation.
Feature Details
Boost Your OTA Technology
Use AutoPi Cloud to plan, execute, and verify OTA updates across mixed fleets. Define which software versions run where, schedule maintenance windows, and combine updates with live diagnostics so vehicles stay operational while software keeps pace with your roadmap.
Initiating OTA Updates
Use the Software Updates view in AutoPi Cloud to create OTA jobs targeting specific devices, fleets, or customer tenants. Select the desired firmware or software release, apply filters (model, region, current version), and queue the update. The platform tracks download, install, and verification states per device, giving you a clear rollout view instead of one-off manual actions.
Scheduling Update Execution
Configure when the device is allowed to install updates: before sleep, at ignition off, or within defined maintenance windows. This prevents disruptive reboots during active trips. Failed installs are automatically retried according to policy, and devices can be configured to pause updates when certain conditions are not met (e.g. voltage thresholds or connectivity limits).
Automatic Update Integration
Assign devices to “channels” such as stable, beta, or test, and let them track the latest approved release on that channel. Devices periodically check for new versions, download in the background, and switch only after verification. Version pinning and per-device overrides allow engineering teams to lock critical units while experimenting on controlled subsets.
Manual Update Commands
For low-level control, engineers can use the web terminal to trigger updates directly on a single
device. Commands such as minionutil.update_release force=True bypass scheduling rules
and are useful for lab units, critical hotfixes, or troubleshooting. This provides a controlled
escape hatch alongside the normal, policy-driven rollout engine.
Diagnostics via CAN & Telemetry
Combine OTA with live diagnostics by streaming DTCs, CAN bus status, modem metrics, and OS-level health into AutoPi Cloud. Use this telemetry to decide which vehicles should receive which updates, and to confirm that a new version actually improves behaviour (e.g. fewer faults, lower reboot rate, or more stable connectivity).
Linux OTA & Device Management
Under the hood, AutoPi runs embedded Linux and a managed update stack. Core OS, containers, and applications can be updated independently, while system services, logs, and configuration files are managed centrally. This allows you to treat each vehicle as a managed node in your infrastructure, with predictable lifecycle management rather than ad-hoc scripting.
Core Feature
OTA Essentials: Update & Diagnose
Combine secure update delivery with real-time diagnostics. AutoPi Cloud coordinates who gets which release, when it is installed, and how devices behave before and after, so OTA becomes a controlled engineering process instead of a best-effort push.
Role-based Control for OTA
Restrict who can create, approve, and execute update campaigns. Use AutoPi Cloud roles to separate engineering, operations, and customer support activities, and keep a full audit trail of which user scheduled which update for which devices.
Health Checks & Safe Rollouts
Define pre- and post-update health checks such as connectivity state, power conditions, or service status. Devices that do not pass checks can be skipped or rolled back to a previous version, reducing the risk of bricking units in the field.
Secure Transport & Integrity
Updates are delivered over TLS with device certificates, and packages are signed and checksummed. Install attempts, successes, and failures are recorded with timestamps and device identifiers to support compliance, incident analysis, and traceability.
Version-aware Data Flows
Tie telemetry and diagnostics to the exact software version running on each device. This makes it straightforward to see how a new release affects error rates, uptime, or connectivity metrics, and to decide whether to expand or halt a rollout.
Direct Integration with Existing Systems
Expose update status, events, and device health over REST APIs and webhooks. Feed this data into your own monitoring stack, ticketing system, or CI/CD tooling so OTA becomes part of your normal release pipeline rather than a separate silo.
Open Pipeline for Diagnostics
Use AutoPi as an open diagnostics endpoint: stream logs, DTCs, and system metrics to your own infrastructure while OTA updates are being rolled out. This gives engineers live feedback on how devices behave under real-world conditions.
Scalable OTA Framework
Operate from pilot fleets to thousands of units with the same tooling. Use templates, device groups, and per-tenant segregation to manage complex deployments without cloning configuration by hand for each customer or project.
Flexible Scheduling & Windows
Define when updates are allowed per region or customer, taking into account time zones, usage patterns, and service windows. Combine these rules with device-side policies to avoid applying updates during critical operations.
Diagnostics-driven Updates
Use alerts and diagnostics as triggers for targeted updates. For example, push a bugfix only to devices exhibiting a specific error pattern, or roll back a release when fault rates exceed a threshold, keeping the fleet stable while you investigate.
