I can't connect my sensor to my LoRa Easy receiver
If you are unable to connect your sensor to your LoRa Easy receiver, first check that the product jumper or switch is correctly set to LoRa mode before powering the sensor.
If not:
1. Power off your sensor
2. Set the switch or jumper to the LoRa position
3. Power the sensor back on
{% hint style="info" %}
Also check that the sensor's LoRa ID has been correctly declared on your receiver.
{% endhint %}
I have a solid orange LED on my sensor, what does that mean?
A solid orange L2 LED is characteristic of a low battery level. We invite you to try powering your transmitter with a newer battery to confirm this hypothesis.
I can't connect my sensor to my LoRaWAN network
If you are unable to connect your transmitter to the network, first check that the jumper is correctly set to LoRaWAN mode before powering the transmitter. The WAN green LED should flash when you power the transmitter. The jumper positions are:
* **LoRaWAN** : one single pin
* **LoRa** **Easy** : two pins
{% hint style="warning" %}
It is essential to declare the transmitter by entering its LoRaWAN keys on your network backend or on your gateway interface **BEFORE connecting the battery**.
{% endhint %}
How do I decode my sensor's battery status in the LoRa Easy receiver's Modbus table?
The battery status must be decoded in the "Status" register.
Here, the read value is 0004 (hexadecimal). Convert this hexadecimal value to 16-bit binary.
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 my sensor's battery status in the LoRa Easy receiver's BACnet objects?
The battery status must be read in the "Battery level" object.
The battery warning level is given in 4 levels:
**0** = 100% remaining\
**1** = 75% remaining \
**2** = 50% remaining \
**3** = 25% remaining (battery replacement needed)
Decoding my sensor frames when I use it in LoRaWAN mode
To decode frames from an Enless LoRaWAN sensor, please use our decoding assistance tools: Which port should downlinks be sent to in LoRaWAN?
Downlinks should be sent to 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 lower battery consumption, but over a shorter distance. Conversely, a higher SF (e.g. SF12) allows data to be sent much farther, even with obstacles, but the transmission is slower and consumes more energy. This can be compared to someone speaking quickly to a person nearby, or slowly and clearly so as 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 my sensor's transmission interval in LoRaWAN mode?
Changing the transmission frequency of a LoRaWAN transmitter is done via Downlink.
The Excel file below allows you to decode frames and generate configuration Downlinks:
**Example**: We want to change the transmission interval 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 transmission interval and press "Enter" to confirm.
Step 3: A new Downlink taking the new transmission interval into account will be generated. Please copy this downlink and paste it into the appropriate field on your gateway. Downlinks should be sent on **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. You only need to 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 takes place.
\***JOIN:** this is a LoRaWAN network access phase that dynamically renews the 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-17/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.
