Issue
How are Elsys LoRaWAN sensors configured with a smartphone using NFC
Product Line
EcoStruxure Building Activate
Environment
- EcoStruxure Building Activate Flex Server
- EcoStruxure Building Activate Partner Portal
Cause
All Elsys sensors are equipped with NFC for easy configuration with a smartphone. There is a requirement to configure these sensors using a Smartphone or tablet using Elsys 'Sensor Settings' application.
Resolution
- Download the ELSYS “Sensor Settings” application from Google Play or the IOS App store and install it on a smartphone or tablet.
- Ensure the mobile device supports NFC. Enable NFC on the device and start the application.
-
Position the mobile device directly on the NFC antenna of the sensor. Ensure both devices remain close and stationary to maintain optimal connectivity.
-
Remove the mobile device. The current settings will be displayed in the application.
-
Set the 'Timebase' to 120 seconds using the application. Remember to revert it to 600 seconds after commissioning!
-
Make note of the following sensor keys:
- DevEUI: The unique ID of the sensor, found in the blue panel at the top.
- AppEUI: Application ID (8 bytes or 16 hex digits). Default is 0, can be changed if needed for the application.
- AppKey: Application unique key (16 bytes or 32 hex digits) that is the encryption key used for messages during every over-the-air activation.
- Tap the sensor's NFC antenna to transfer the new settings after making the desired changes. Ensure the application confirms the updated settings.
- Wait for the sensor to reboot, indicated by the LED flashing. The sensor settings should now be updated.
- Validate your settings by reading the NFC data after the sensor has restarted. Verify that settings have been applied by using the ‘Read’ functionality in the app and touching the sensor’s NFC antenna.
- Remember to change the 'Timebase' back to 600 seconds after the commissioning is completed!
