The Telematics Control Unit (TCU) development platform provided by SanCloud is a reference design based around the AM335x architecture. The SanTrack cloud platform provides data collection, processing, visualisation and device management services. The open source Thingsboard project can be used as an alternative cloud platform to provide the same services.

The TCU software image will be based on the AGL Telematics Profile.
The agl-telematics-demo-recorder app will be used to collect telematics data and send it to a SanTrack or Thingsboard instance via the MQTT protocol. This app may be extended to add any extra functionality which is required.
Cloud Software
The SanTrack IoT Web Platform provides the following features which will be used in this reference design:
- Device management: The status of each registered device can be monitored using the cloud interface. Devices can be assigned to a particular end user or project to aid organisation and to delegate administrative responsibilities.
- Data collection: SanTrack includes an MQTT server which will accept data from TCUs. MQTT data may be sent over an SSL connection for increased security.
- Data storage: Once received via MQTT, data can be stored in a PostgreSQL, Cassandra or Timescale database. These backend databases can be queried, backed up, etc as required.
- Data analytics: SanTrack provides data query tools, data visualisation and a rule engine which can be used to automate data analysis. Alarms can be configured so that the administrator is notified on important events.
