2.3 Configuration
To deploy the sensor, download the latest LoRa Tool Android App to setup LoRaWAN® credentials
and other preferences :
Always validate your settings by reading the NFC data after the sensor has restarted.
Configuration can be done only via NFC.
No USB port available for the user.
2.4 Power ON/OFF
The sensor is shipped completely off to prevent battery consumption during storage. It is therefore
necessary to carry out a first power-on prior to commissioning.
Move the NFC antenna of the mobile (the exact position varies depending on the model of the
smartphone) to the sensor antenna, in the area shown in the figure:

e n g i n k o . s u p p o r t . c e n t e r - https://www.enginko.com/support/
At the first power-on, sensor will take from 1 to 5 minutes to give an effective measure of PM.
In case of long period inactivity, if necessary, is possible to shut-off again the sensor to prevent
battery consumption, via downlink or with LoRa Tool App:

Period is the interval (in minutes) between one measure and the next one. The sensor sends one
measures for every transmission. Value can be between 15 and 65535 minutes (default: 30 minutes).
Period interval can be set with App or with downlink command.
3.2 Temperature
3.3 Pressure
3.3.1 Altitude compensation
When the sensor is not installed at the sea level, the reading of barometric pressures at other
elevations must be compensated. Set the right altitude value with LoRa Tool app:
Value can be from -300 to 3000 meters.
Altitude can also be set with downlink command.

3.4 Humidity
3.5 PM
The PM measurement principle is based on laser scattering. This technology, together with high-
quality and long-lasting components, enables precise measurements from its first operation and
throughout its lifetime of more than ten years
3.5.1 Mass concentration/particles number
As default particulate matter is expressed as mass concentration (in μg/m3). If “Particles” is set to ON,
particulate matter is expressed as number concentration (in #/cm3):
4 LoRaWAN network
The sensor is compliant with LoRaWAN® specification 1.0.2, regional 1.0.2b.

4.1 Activation
The device supports the following activations on a LoRaWAN® network:
NONE: sensor not activated1.
OTAA: the JoinEUI and the AppKey not setted, must be written to the device;2.
OTAA MCF88: Over the air activation, fixed keys: JoinEUI = 904e915000000001, AppKey on3.
request;
OTAA ENGINKO: Over the air activation, fixed keys: JoinEUI = 904e915000000001, AppKey on4.
request;
ABP: requires writing to the device of NwkSkey, AppSkey, DevAddr.5.

e n g i n k o . s u p p o r t . c e n t e r - https://www.enginko.com/support/
The device exits factory activated with NONE mode. On request devices can be shipped aleady
activated.
Note: in OTAA AppKey is write only, in reading the field will always be empty, even if set.
4.2 Other settings
Network settings:
please keep “Any” settings. Change it only if Objenious network is used (default_ any).
Network type:
LoRa syncword can be setted as “private”(0x12) instead “public” (0x34), but the NS must be setted
accordingly (default: public).
Band:
select the right LoRaWAN ® band settings accodingly to country requirements.

DST:
set to change DST (default: none).
No time sync:
set to disable time synchronization request (default: enabled).
Normally sensor asks for a time sync at every power on (uplink starting with 01) or, if enabled, once a
week.
If not handled in the right way can cause a unnecessary battery consumption.
Please check chapter 2.1 DATA FRAME FORMAT.
UnConfirmed:
set for unconfirmed uplinks (default: confirmed uplink).
Single join/day:
set for to allow only one join per day (default: multiple join allowed).

5 Passwords
The device can be protected by passwords, to avoid unauthorized persons to read data or modify
parameters.
As default passwords are equal to 0.
Allowed values range from 0 to 999999999 (only numbers).
To change the passwords, set the new values with the LoRa Tool App:

https://www.enginko.com/support/ Printed on 2022/09/11 20:17
Once the passwords are setted, to gain access from LoRa Tool to the sensor, open the App:
and set the right values before reading from the device:

e n g i n k o . s u p p o r t . c e n t e r - https://www.enginko.com/support/
To bring back the sensor to factory default and reset the passwords, a reset code must be requested
to enginko (please provide the DevEUI of the sensor when you ask for that code).
6 Configuration file
WIth LoRa Tool App is possible to configure the device using an XML file, instead to manually adjust
the parameters (for details about the file format please ask to enginko). This is very useful especially
in case of multiple devices configuration.
With “Save” button an XML file with the actual configuration of the sensor will be generated. This is
useful to store or clone the configuration, or to send it to enginko's support if needed.

6.1 Multi devices configuration
WIth LoRa Tool App is possible to configure many devices in an easy way.
For multi-configuration is needed at least one XML file with the parameters to set.
Settings on this file will be applied to all the sensors.
With an additional XLS file is possible to load different LoRa configuration parameters (Activation
Type, AppKey, AppEUI, NetKey, DevAddress, Band, Private option) for each sensor, based on DevEUI.
When the sensor is approached, if one parameter is different from files, the APP will ask you if you
want to overwrite.
XLS is prevailing on the XML, so if both files are enabled, if the DevEUI of the device matches one of
the DevEUIs in the XLS file, LoRa parameters will be setted from this one.
These configuration can be done in the in the Settings:
Enable or disable the use of the general configuration by file;
Enable or disable the use of the specific configuration by file;
Verify the passwords;
Writing the passwords.
