The default settings are suitable for most applications. Should you, however, need to change something, the general device settings via the gear symbol at the top right corner provides the settings illustrated below. The following settings are available:
The following parameters control the (Bluetooth) communication with the MARWIS device:
|Device connection activated||On||
Connection to the MARWIS device enabled/disabled.
Communication with the MARWIS is active and should remain activate all the whole time. This parameter is merely for test purposes.
|Communication Timeout [ms]||150||The communication timeout for Bluetooth communication between the smartphone/tablet and MARWIS in milliseconds.|
|Retries on error||3||The number of repeats after errors/interruptions of the device communication, before the error is forwarded as a timeout.|
|Heartbeat rate [ms]||2000||The device status is checked within the chosen time frame in milliseconds.|
|External UMB polling rate [ms]||5000||UMB request frequency in milliseconds.|
|Default device UMB address||40961||The standard UMB address for the MARWIS used when sensor channels are created through the app. It is preset but can be changed by the user.|
|Android UMB address||61441||The standard UMB address for the Android device. It cannot be changed and is preset in the sensor.|
|Update channels on connection||OFF||With the activation of this option, information of all the channels is saved and re-read when the sensor is next connected.|
|Target device||MARWIS-UMB_XXXX.YYYY||Name of the coupled MARWIS. The XXXX.YYYY represents the serial number of the device.|
|Station ID||80115||Is generated from the serial number. This value cannot be changed and is specific to each MARWIS.|
Besides the measured values on the Android device, the transmission of the data to a server for further processing is an essential function of the app.
Following are the parameters that can be configured for server connection:
|Server connection enabled||OFF||
The connection to the server (SmartView, ViewMondo) is enabled/ disabled.
The MARWIS app uses the station ID to identify itself to the server. In order to connect to the server, this setting and the basic device connection must be activated.
If required, port forwarding for the TCP port must be configured on your router and the TCP port must be allowed on your firewall.
The DNS host name or IP address of the server needs to be configured, and the server connection needs to be turned on. If a special TCP port was configured, the corresponding port number should be entered.
|(SmartView) Server URL||The DNS name or IP address of the server.|
|Server port||The TCP port for the server connection|
|Communication interval [s]||60||
The interval (in seconds) in which data is transferred to the server.
The data collected in the MARWIS app is transferred to the server within the configured “communication interval”, which determines how often data transmission occurs.
|Communication timeout [s]||30||Communication timeout in seconds for server connection|
|Transmission Interval [ms]||1000||
The interval (in milliseconds) in which the measurement values are made available for transmission.
Should the connection to the server be interrupted, the data is cached in the app and then transferred to the server as soon as the connection is restored.
The following parameters control how the data is displayed on the main “dashboard” screen of the app.
|Trace path width||10||The width/thickness of the travelled path shown on the map (on the road).|
|Trace remove interval [s]||1200||The interval (in seconds) until the road condition trace on the road map slowly fades out.|
|Translate road condition value||On||This will activate the translation of the numeric road conditions into the related condition description (e.g., dry instead of 0)|
The following parameters configure the automatic firmware update for the MARWIS:
|Enable firmware update||On||
Automatic check for new device firmware and automatic download.
If the firmware update is active/switched on, the MARWIS app checks at start-up and regularly during operation whether a newer firmware version for the MARWIS UMB sensor is available. If so, it is downloaded and saved, and the user informed about it.
Each time you connect to the MARWIS-UMB sensor via Bluetooth, it checks whether a newer firmware version is available and, if so, whether the firmware should be downloaded to the device. Upon confirmation, the firmware is transferred to the MARWIS-UMB sensor and the MARWIS sensor automatically restarts.
