I can't connect my sensor to my LoRa Easy receiver
If you can't connect your sensor to your LoRa Easy receiver, first check that the product switch is set to LoRa mode before powering the sensor.
If not:
1. Set the switch or jumper to the LoRa position (position 0)
2. Press the push button so the mode change is taken into account.
{% hint style="info" %}
Also check that the sensor's LoRa ID has been correctly declared on your receiver.
{% endhint %}
When I remove the battery from my sensor, it keeps working. How do I turn it off completely?
The fact that the sensor keeps working even if the battery is removed is because it includes a supercapacitor that acts as an energy reserve. It may be that this supercapacitor has retained enough energy to power the product for some time, even when the battery is removed. If you want to completely turn off the product, you need to discharge the supercapacitor. The procedure is described below: \
How do I decode the battery status of my sensor in the Modbus table of the LoRa Easy receiver?
The battery status must be decoded in the "Status" register.
Here, the read value is 0004 (hexadecimal). Convert this hexadecimal value to binary on 16 bits.
0004 (hex) = 00000000 0000**01**00 (binary)
Bits 3 and 2 **in red** are the ones that provide the information about the battery level:
**00** = 100%\
**01** = 75%\
**10** = 50%\
**11** = 25%
How do I decode the battery status of my sensor in the BACnet objects of the LoRa Easy receiver?
The battery status must be read in the "Battery level" object.
The alert level for the battery is given on 4 levels:
**0** = 100% remaining\
**1** = 75% remaining \
**2** = 50% remaining \
**3** = 25% remaining (battery replacement to be planned)
I can't connect my sensor to my LoRaWAN network
If you can't connect your transmitter to the network, first check that the switch is set to WAN mode before powering the sensor.
{% hint style="info" icon="circle-info" %}
The **change** of the switch position is not **taken into account** only when the product is **powered off**. Make sure your product is completely powered off before adjusting the switch.
{% endhint %}
{% hint style="warning" %}
It is essential to declare the sensor by entering its LoRaWAN keys on your network backend or on your gateway interface **BEFORE connecting the battery**.
{% endhint %}
Decode my sensor frames when I use it in LoRaWAN mode
To decode the frames of an Enless LoRaWAN sensor, please use our decoding tools: Which port should downlinks be sent to in LoRaWAN?
Downlinks should be sent on port number 1.
What is a Spreading Factor?
The Spreading Factor (SF) in LoRaWAN is used to define how a sensor sends its data. The lower the SF (e.g. SF7), the faster the message is sent, with low battery consumption, but over a shorter distance. Conversely, a higher SF (e.g. SF12) makes it possible to send data much farther, even with obstacles, but the transmission is slower and consumes more energy. It can be compared to someone speaking quickly to someone nearby, or slowly and clearly to be heard from far away. The choice of SF is therefore a compromise between radio range, battery life, and transmission speed.
How do I change the transmission period of my sensor in LoRaWAN mode?
Changing the transmission frequency of a transmitter in LoRaWAN is done via downlink.
The Excel file below allows you to decode frames and generate configuration downlinks:
**Example**: We want to change the periodicity of a 600-023 transmitter to 15 minutes.
Step 1: Please open the attached Excel file and go to the sheet for the transmitter in question.
Step 2: Please change the periodicity and press "Enter" to validate.
Step 3: A new downlink taking the new periodicity into account will be generated. Please copy this downlink and paste it into the appropriate field on your gateway. Downlinks should be sent on the **port 1**.
How do I switch from one LoRaWAN network to another?
To switch a sensor from one LoRaWAN network to another, you do not need to physically intervene on the sensor. All you need to do is remove it from the old LoRaWAN network, then declare it on the new LoRaWAN network.
Indeed, every 24 hours, the transmitters send a LinkCheckReq message that must be confirmed by a LinkCheckAck from the network. As long as the LinkCheckReq messages are confirmed by a LinkCheckAck, the transmitter will not send a new JOIN. If the transmitters are still declared on the old LoRaWAN network, they remain connected to it. On the other hand, if they are declared on the new LoRaWAN network and are no longer provisioned on the old one, the switch to the new LoRaWAN network is carried out.
\***JOIN:** this is an access phase to the LoRaWAN network that makes it possible to dynamically renew network parameters between the end device and the LoRa Server.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://enless.gitbook.io/centre-aide/guides-installation/documentation-en/products/editor-1/troubleshooting.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
