Datasheet

2. Configuration Manual Setup

In this documentation you can find all the information to setup your gateway (Wi-Fi, LoRa server, etc.)

3. LoRaWAN Server Configuration

3.1 Configure the ecoSignal Gateway for the TTN LoRaWAN server

There are 4 steps:

put your gateway in configuration mode
change the parameters of the LoRa server connection
update your frequency plan to match the TTN plan
put your gateway back in normal mode

Each step is detailed below.

3.1.1 Put the gateway in configuration mode

Connect your gateway in ethernet (simpler but wifi works also) to the same network your browser is connected to
Push one time on the user button, once the LED blink your gateway is in configuration mode

Go to the configuration page in a web browser:

http://ecosignal-loragw-xxxx-e.local/#/lora-settings

where xxxx is the last 4 characters of the ETH-MAC info displayed on the sticker on the back of your gateway

3.1.2 Go to the LoRaWAN Configuration page

Click on the LoRaWAN Configuration link to go to the LoRaWAN Configuration page
Change the following settings:
1. input the Gateway EUI provided by The Things Network when you registered your gateway
2. input the LoRaWAN Network Server URL that you use, for instance:
```
eu1.cloud.thethings.network
```
3. set the LoRaWAN Network Server Port Up to
```
1700
```
4. and set the LoRaWAN Network Server Port Down to
```
1700
```

Your lorawan settings should look like:

3.1.3 Change the frequency plan by updating your SX1302 Settings

Click on the link SX1302 Settings Configuration to go the configuration page of the SX1302
upload your frequency plan that you use with TTN.
1. Click the button Choose file at the bottom of the page
2. A default json configuration for EU-868 is provided below (you can download the file by clicking on its name, in blue below).

}

You can upload the file using the interface shown at the bottom of the configuration page (an illustration is given below):

DO NOT FORGET TO SAVE

You can also download the current configuration, update it and upload it.

3.1.4 Return to normal mode

Once you have saved all your changes
Go back to normal mode by pressing one time on the user button
If every things is correctly configured, your gateway LED should show a solid GREEN

4. Factory reset for Debug version

4.1 Factory reset of the binary

When programming the gateway or another esp32 chip on the your PC, while your gateway is plugged-in, you might flash a wrong firmware or a faulty firmware on your gateway. If you need to reflash a correct firmware here are some firmwares you can use:

You can use the esptool.py tool from espressif with the following command:

esptool.py write_flash 0x0 stg-micro-lora-gw_0.2.1-lyon1.bin

4.2 Factory reset of the binary and the provisioning data

You need to download:

the partition configuration file (below) mfg_config.csv
the security certificates of your gateway on https://pucs.wavebricks.com
1. the device certificate (device.crt)
2. the device private key (device.key)
the json configuration file

mfg_config.csv

key,type,encoding,value
mfg_ns,namespace,,
cert,file,binary,device.crt
priv_key,file,binary,device.key
ca-ota-cert,file,binary,ca_ota.crt
json_conf,file,binary,conf.json
