 +===== 3. Measures ===== 
 + 
 +On each reading of the sensor by LoraTool, the measured distance is shown on the main page: 
 + 
 +{{  :wiki:manual_egk-lw20l00:sc2_dist.jpg?400  |sc2_dist.jpg}} 
 + 
 +Once provisioned on a LoRaWAN® network, the device sends the distance & timestamp to the server via uplink. 
 + 
 +==== 3.1 Level settings ==== 
 + 
 +Level measurements are carried out according to few parameter settings. A target over the defined range cannot be detected. Read and write of parameters can be done using LoRaTool App. They have a default value and can be modified to be tailored on the specific use case. 
 + 
 +Meaning of parameters is related to following diagram. The "REFERENCE" (distance=0mm) is the top surface of the sensor: 
 + 
 +{{  :wiki:manual_egk-lw20w00:distances.jpg?300  |distances.jpg}} 
 + 
 +=== 3.1.1 Start [mm] === 
 + 
 +Starting point of the measurement (in mm from "REFERENCE" point). 
 + 
 +Values can be set from 350 to 7000: 
 + 
 +{{  :wiki:manual_egk-lw20l00:start_1.jpg?400  |start_1.jpg}} 
 + 
 +__Default: 400__ 
 + 
 +A target within the "Start [mm]" distance will result at a “Start” distance. 
 + 
 +The "Start [mm]" value is also related to other level parameters. Contact Angel4Future in case of assistance. 
 + 
 +=== 3.1.2 End [mm] === 
 + 
 +Range of measure (in mm, from "Reference" point). 
 + 
 +Values can be set from 0 to 7000: 
 + 
 +{{  :wiki:manual_egk-lw20l00:end_1.jpg?400  |end_1.jpg}} 
 + 
 +__Default: 7000__ 
 + 
 +The END value can be inferred from a physical measurement of obtained from the sensor itself using the function "Calculate Floor" 
 + 
 +{{  :wiki:manual_egk-lw20l00:end_1.jpg?400  |Floor_1.jpg}} 
 + 
 +__After executing this function, perform a new reading and validate the value obtained.__

 + 
 +=== 3.2.3 Humidity === 
 + 
 +===== 4 LoRaWAN network ===== 
 + 
 +The sensor is compliant with LoRaWAN® specification 1.0.2. 
 + 
 +{{  :wiki:manual_mcf-lw12co2e:activation2_0.jpg?400  |activation2_0.jpg}} 
 + 
 +==== 4.1 Activation ==== 
 + 
 +The device supports the following activations on a LoRaWAN® network: 
 + 
 +  - **NONE**: sensor not activated 
 +  - **OTAA**: the JoinEUI and the AppKey not setted, must be written to the device; 
 +  - **OTAA MCF88**: Over the air activation, fixed keys: JoinEUI = 904e915000000001, AppKey on request; 
 +  - **OTAA ENGINKO**: Over the air activation, fixed keys: JoinEUI = 904e915000000001, AppKey on request; 
 +  - **ABP**: requires writing to the device of NwkSkey, AppSkey, DevAddr. 
 +{{  :wiki:manual_mcf-lw12co2e:activation1_0.jpg?400  |activation1_0.jpg}} 
 + 
 +The device exits factory activated with **OTAA ENGINKO**  mode. On request devices can be shipped already activated. 
 + 
 +Note: in **OTAA**  AppKey is write only, in reading the field will always be empty, even if set. 
 + 
 +---- 
 + 
 +=== Time sync === 
 + 
 +{{:warning.png?50}} 
 + 
 +Normally sensor asks for a time sync at every power on (uplink starting with 01) or once a week. If no or wrong reply received it will retry after 1 week. 
 + 
 +If not handled in the right way can cause a unnecessary battery consumption (battery life < 2 years). 
 + 
 +Please check chapter 2.1 [[:data_frame_format|DATA FRAME FORMAT]]. 
 + 
 +==== 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. 
 + 
 +{{  :wiki:manual_mcf-lw12co2e:activation3_0.jpg?400  |activation3_0.jpg}} 
 + 
 +**DST**: set to change DST (default: none). 
 + 
 +**No time sync**: set to disable time synchronization request (default: enabled). 
 + 
 +**UnConfirmed**: set for unconfirmed uplinks (default: confirmed uplink). 
 + 
 +**Led OFF**: set to disable the led. 
 + 
 +**Single join/day**: set for to allow only one join per day (default: multiple join allowed). 
 + 
 +**Period**: time interval between two measures (in minutes). 
 + 
 +**Clock timed**: set to sincronize the reading with the internal clock. 
 + 
 +**Accelerometer**: set to enable asynchronous measure in case of shaking (useful for debug). 
 + 
 +{{  :wiki:manual_egk-lw20l00:bt_set1.jpg?400  |bt_set1.jpg}} 
 + 
 +===== 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: 
 + 
 +{{  :wiki:manual_mcf-lw12co2e:password1_0.jpg?400  |password1_0.jpg}} 
 + 
 +Once the passwords are setted, to gain access from LoRa Tool to the sensor, open the App: 
 + 
 +{{  :wiki:manual_egk-lw20l00:bt_scan.jpeg?400  |bt_scan.jpeg}} 
 + 
 +and set the right values before reading from the device: 
 + 
 +{{  :wiki:manual_mcf-lw12co2e:password2_0.jpg?400  |password2_0.jpg}} 
 + 
 +To bring back the sensor to factory default and reset the passwords, a reset code must be requested to Angel4Future (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 Angel4Future). 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 Angel4Future's support if needed. 
 + 
 +{{  :wiki:manual_mcf-lw12co2e:files_rev0.jpg?400  |files_rev0.jpg}} 
 + 
 +==== 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. 
 + 
 +{{  :wiki:manual_mcf-lw12co2e:multiple_rev0.jpg?400  |multiple_rev0.jpg}} 
 + 
 +For details on files format please ask to Angel4Future. 
 +
