Getting Started

Software Prerequisites

Once you have your Raspberry Pi or Server set up download the following (instructions below):

Install the software prerequisites

On your server or Raspberry Pi, run these commands:

$ sudo apt-get update

$ curl -fsSL get.docker.com -o get-docker.sh && sh get-docker.sh

$ sudo apt install python3-pip -y

$ sudo pip3 install docker-compose==1.12.0

$ sudo apt install git -y

Follow these commands only if you are using a Raspberry Pi.

$ sudo apt install mosquitto -y

$ sudo touch /etc/mosquitto/conf.d/bridge.conf

$ sudo nano /etc/mosquitto/conf.d/bridge.conf

add the following:

connection bridge-central
address *CENTRAL-SERVER-IP*:1883
topic forest out 0

$ sudo systemctl restart mosquitto

Development Environment Prerequisites

Make sure you have installed on your computer:

Running The App

Getting The App Running (Raspberry Pi)

$ git clone https://github.com/saycel/black-rock-forest-store-and-forward

$ cd black-forest

Add the following to .env file

POSTGRES_PASSWORD=postgres
POSTGRES_DB=brfc
PYTHONPATH=/brfc

$ sudo docker-compose -f docker-compose.raspberry.yml build

$ sudo docker-compose -f docker-compose.raspberry.yml up -d

Getting The App Running (Linux)

$ git clone https://github.com/saycel/black-rock-forest-store-and-forward

$ cd black-forest

Add the following to .env file

POSTGRES_PASSWORD=postgres
POSTGRES_DB=brfc
PYTHONPATH=/brfc

$ sudo docker-compose build

$ sudo docker-compose up

Getting The App Running (Mac)

We recommend running the app in Vagrant if you are using a Mac. Follow the steps to install and run the project:

$ brew install vagrant

$ vagrant plugin install vagrant-docker-compose

$ cd black-forest

$ vagrant up

Note: the ip of the VM is 192.168.33.10

Updating The App

$ cd black-forest

$ git pull

$ sudo docker-compose stop

$ sudo docker-compose build

$ sudo docker-compose up

Adding Your First User

To start using the platform you need to first add a user by sending a json post request to http://SERVER-IP:2323/user/register with a username and password.

{	
	"email": "[email protected]",
	"password": "4veryS4vePass!!"
}

Login With The User You Just Created

Once you have added a user, to get a token send a post request to http://SERVER-IP:2323/user/register with the following json payload:

{	
	"email": "[email protected]",
	"password": "4veryS4vePass!!"
}

you will receive a response with a JWT token like this:

{
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6InRlc3RlckBnZXJtYW4uY29tIiwidmFsaWRfdW50aWwiOiIyMDIwLTAzLTE2IDE1OjMzOjQ2LjEwNDEyMCJ9._g1OMeiEoLaM7e3eiSjHcV5pKi05MaMzJVzNTMq8LL8"
}

Test To See If The App Is Running

In order to know if the app's REST API is up and running,first make sure the the pc where you installed Postman and the Server or Raspberry Pi where the app is running are on the same LAN. Then follow these steps:

  1. Get the IP address of your Server or Raspberry Pi
  2. In Postman create a post request
    1. In the url textbox: http://RPI-IP:2323/login
    2. Click in the Authorization tab and choose Basic Auth type.
    3. The username and password are the same as the ones you added earlier.
    4. Click the send button next to url textbox.
    5. You should receive a json response: {"message": "success"}

Add Data To The Database Using HTTP

Send a GET request using the following API format:

Generic:

http://RPI-IP:2323/sensor/collector/<app_key>/<net_key>/<device_id>/?chN=n

Example:

http://10.0.0.115:2323/sensor/collector/1234/abc/x1v3/?ch1=1&ch2=2

  1. open postman
  2. use http://RPI-IP:2323/<app_key>/<net_key>/<device_id>/?chN=n
  3. click the send button next to url textbox
  4. after send the request if everything goes ok, you will receive a success message

Add Data To The Database Using MQTT

Send an MQTT request using the following format:

host:CENTRAL-SERVER-IP port:1883 topic: forest protocol: mqtt/tcp

Generic:

     {
            "app_key": "application key",
            "device_id": "node unique identifier",
            "net_key": "network key",
            "channels": {
                "ch1": "float as string",
                "ch2": "float as string",
                "chN": "float as string"
            }
        }

Example:

        {
            "app_key": "1",
            "device_id": "3",
            "net_key": "2",
            "channels": {
                "ch1": "1",
                "ch2": "2"
            }
        }

Get All Database Records

Send a GET request using the following API format:

Generic: http://RPI-IP:2323/sensor/all

Example:
http://10.0.0.115:2323/sensor/all

Add the following request headers:

Authorization=JWT-TOKEN-GENERATED-BEFORE

  1. open postman
  2. use http://RPI-IP:2323/sensor/all
  3. click the send button next to url textbox
  4. In case you have records in the db you will receive a list of json
  [
      {
          "app_key": "1",
          "channels": {
              "ch1": "1",
              "ch2": "2"
          },
          "device_id": "3",
          "net_key": "2"
      },
      {
          "app_key": "dd",
          "channels": {
              "ch1": "1",
              "ch2": "2"
          },
          "device_id": "ff",
          "net_key": "ff"
      }
  ]

Swagger API

We have swagger documentation, which you can find here: http://165.22.191.125:2323/swagger/

Upload csv File

Required csv Format

The first row must have the names of the columns. The second row must have the units of the columns. From the third line on, you will have your data. For example:

temperature, pressure
°C, hPa
12.0, 1000.0

The previous will be load in the database as

id app_key net_key device_id value created_at field_name unit_string
1 from_csv from_csv from_csv 12.0 2014-11-2800:00:00 temperature °C
2 from_csv from_csv from_csv 1000.0 2014-11-2800:00:00 pressure hPa
