Functional Scope

The YUKI Module A1 combines several communication and positioning technologies in a compact module:

• Cloud connectivity via LTE-M
  All cellular and network configuration is preconfigured and encapsulated in the module. The user does not have to enter APN data or implement network authentication.
• GNSS positioning
  The integrated geolocation function regularly provides position data, which can be retrieved via the UART protocol or automatically transmitted to the cloud.
• Bluetooth Low Energy (BLE)
  Can optionally be enabled for local communication, e.g. for on-site configuration or pairing with mobile devices.
• Cloud dashboard
  A web-based user interface allows access to collected data, device status, location history, as well as alarms and configuration.
• REST API
  A documented API allows automated access to device and status data, as well as remote control and integration into your own systems.

Typical Use Cases

The module is particularly suitable for applications where classic network connectivity is not possible or would be too complex:

• Condition monitoring of decentralised machines
  Continuous acquisition of sensor data or states with direct cloud connectivity, e.g. at remote locations or on mobile machines.
• Remote maintenance of devices in infrastructure systems
  Access to diagnostic functions, reboot commands, or parameterisation – even without local network connectivity.
• Location tracking for mobile assets
  Regular GNSS position reporting for vehicles, containers, or mobile installations.
• Alarming & monitoring for power supply systems
  Monitoring of critical thresholds (e.g. power failure, temperature) with automatic cloud-based alarming.

Firmware Updates (OTA)

The YUKI Module A1 is automatically updated by the manufacturer via the cellular connection as soon as security-relevant changes or bug fixes are available. The user does not have to take any action; the update is performed transparently in the background.

The current firmware version can be queried via the UART interface. This enables the developer to document the firmware version in use or to check compatibility.

Note: Manually triggering firmware updates is not intended. Updates are only initiated by the manufacturer.
