     User manual (this document) NOTE If you are using the trial version of the XDL120, the features and usage as described in this manual are identical to the full version with the exception of the logging time. The trial version only allows for logging of up to 30 minutes per log.

  • Page 5: Feature Details

    2.1 Accurate logging of sensor samples with timestamps The XDL120 allows logging with high data rates for all on board sensors except the acoustic noise sensor without loss of data, when individual sensors are configured. Data is homogeneously timestamped with millisecond resolution based on the FreeRTOS system time.

    Devices view, e.g. from the explorer window. The binary will now be flashed to the XDK  After the binary file was flashed, the XDK will automatically start the flashed application. The XDL120 is now ready to log and stream sensor data.

  • Page 9: Configuration

     An alternative method is installing python and upgrading required package via single utility called “Anaconda” https://www.anaconda.com/download/ NOTICE: The following script files included in the XDL120 shipment are also needed for the conversion and must be available in the same folder as the datalogger.py: convert.py, custom_binary_parser.py, custom_dataframe_generator.py, msgpack_binaryparser.py, outputformater.py, xdk_wifi_datalogger.py.

  • Page 10: Sensor Configuration

    When data logging is started it needs to be stopped and the XDK turned off before the SD card should be removed. This is necessary because the XDL120 does not integrate auto detection regarding a removed SD card and will show unintended behavior.
  • Page 11 </bmi160> NOTICE The <marker> section of the config.xml is needed for internal use and must be enabled (true) for the XDL120 to work correctly. Please do not change this configuration. The full list of all parameters is summarized in Table 3 to Table 8. For more details, please refer to the data sheets of the respective sensors.

    Data format: The XDL120 offers the possibility to either store / stream files in binary or in MessagePack format. MessagePack is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON and is aimed for users who want to integrate data from XDL120 directly into a third-party application via WLAN streaming.

  • Page 23: Access Control

    This is especially the case in use case scenario 3. Classification whether data is sensitive or not depends on the use case and has to be done by the user. In summary, Bosch suggests a strong protection of the confidentiality, a very strong protection of the integrity, and a strong protection of the availability.

  • Page 24: Access To Networks

    4.7 Termination of service If the life cycle of the XDL120 ends or the purchased licence expires, the user should remove all external memory storages. In addition, the user should delete all data and perform a secure overwriting. This can be done by sending a command "E”...
