The following guide describes how to configure a LoRaWAN device from KELLER. A German version is available as PDF.
The software GsmConfiguration/GsmSetup is required for the configuration. The software can be downloaded under the following link: https://keller-druck.com/en/products/software/desktop-applications/gsm-setup-for-remote-transmission-units
Connect the ARC1 device to a Windows-PC with the interface converter K114 and then start the software GsmConfiguration. ADT1 devices can be connected using a Micro USB-cable.
Select the Comport Number of the connected device and then press the button Read Configuration. The current settings of the device are now read out and displayed in the software.
ATTENTION: Changes to the configuration are only transferred to the device if the Write Configuration button is pressed.
The parameters required for transmission can be changed in the communication settings.
The following settings can be changed:
The activation method OTAA (Network-Session-Key and App-Session-Key are exchanged/created during the first connection) or ABP (Manual entry of keys) can be selected. Depending on the selection of the activation method, the input fields are activated.
The devices EUI (Unique Device Identification) cannot be changed. The EUI is registered at the network server.
The unique identification number for the application with which the data is further processed is entered here.
Device Address / Network Session Key / App Session Key
These settings must be entered for the ABP activation method.
The data can be sent with confirmation (confirmed) or without confirmation (unconfirmed) of the network server.
If ADR= ON () is selected, the transmission power (SF) of the device is adapted to the ambient conditions by the network server. An optimal ratio between range and power is set. If ADR=OFF, the automatic power adjustment is deactivated and the device transmits with the power set in the “Data Rate” field.
Here the transmission power can be set, whereby the setting 0 SF12/125kHz achieves the highest power and consequently the highest range (and also the highest energy consumption). With the setting 6 SF7/250kHz the smallest range is reached.
With the Power Index setting the transmission power can be adjusted to the antenna. If an antenna with amplification is used, the transmission power can be reduced so that the transmission power corresponds to the permissible standard.
The device can send useful information such as battery voltage, battery capacity, humidity etc.
Devices with Firmware>20.34 can have a ReJoin interval that helps to fix troubles with LoRa Network Servers (Hello Swisscom)
In the tab [Error/Status] the current status of the device can be viewed. Possible errors during transmission as well as errors during measurement of the connected sensors are displayed.
Measuring Pressing the Measure button triggers a measurement (without transmission). The measured values are displayed below the button.
Send Measure-Data LoRa A measurement is triggered and the measured values are transmitted via LoRaWAN. If necessary, a JOIN is carried out before the measurement data transfer.
Send Configuration LoRa By pressing this button, all settings of the device are transmitted one after the other in different individual messages via LoRaWAN. Attention: Due to the limitations of the transmission (frequency band usage regulations) the transmission may take some time (minutes to hours).
