LoPy Nano-gateway and private lora-server installation

In this page we are going to:

• Install open source private LoRa server (by Orne Brocaar)
• Setup LoPy as single channel nano gateway
• Send data from LoPy node

Install private LoRa server:

We use LoRa Server Setup Ansible playbook to install all the LoRa server component:

For testing use vagrant to install the server to virtual machine in our local pc (We will update the guide to deploy later):

• Download and install vagrant to your machine vagrant download page
• Install git to your machine
• Clone the LoRa Server Setup repository Reference:

 git clone https://github.com/brocaar/loraserver-setup.git

• Go to loraserver-setup folder (In terminal or CMD)

 cd loraserver-setup

• Run vagrant up

 vagrant up

• The virtual machine will boot and install all the component (This can take a while)
• Note: we can access the server web interface at https://localhost:8080/ (As a self-signed certificate is used, your browser will prompt that the certificate can't be trusted. This is ok for testing)
• We can use our machine IP address and port 1700 for our gateway to forward the package (We do this later in setup LoPy as Nano Gateway below)

Setup LoPy as a Single channel nano gateway: (Reference Pycom Forum Github Code

• Update LoPy firmware to 1.6.7.b1
• Download the code
• Edit the config.py file to setup: Gateway ID, Server IP, Server Port, Wifi Access Point for LoPy to connect to the network.

 GATEWAY_ID = '11aa334455bb7788'
 SERVER = 'ip.address.here'
 PORT = 1700
 WIFI_SSID = 'my-wifi'
 WIFI_PASS = 'my-wifi-password'

• • Note: We can get gateway id by execute these code in LoPy (Referenece TTN):

 from network import LoRa
 import binascii
 lora = LoRa(mode=LoRa.LORAWAN)
 print(binascii.hexlify(lora.mac()).upper().decode('utf-8'))

• Copy the code to the 'flash' folder of LoPy:

 Via FTP:
 Follow this reference to connect to LoPy via FTP pycom

• Reset LoPy

We should be able to see the message from gateway from MQTT server with this topic (Reference loraserver):

mosquitto_sub -t "gateway/#" -v

Send data from LoPy node:

• Register node in server

• Send data from node (LoPy)

• Subscribe to node data from server:
