LoRa Mote Emulator

This is a useful tool to test LoRa server.

To emulate end devices (a.k.a. Motes in LoRaWAN ™ protocol)

Support LoRaWAN ™ 1.0.2 & 1.1 protocol

Using Gateways from Semtech ™

System Requirements

• Ubuntu
• Python(>=3.6, mandatory)

Installtion

PYPI

• Use pip to install lora-mote-emulator:

  pip install lora-mote-emulator

MANUALLY

• Use pip to install pipenv:

  pip install pipenv

• Clone this repo into a directory:

  git clone https://github.com/houluy/lora-mote-emulator.git

• Use pipenv to create a virtual Python environment and install all the dependencies:

  pipenv install

• Build the project:

  python -m build 

Here, if there is not Python 3.6 in your system, a warning will occur, and no package will be installed. It is perfect to install Python 3.6 from source. Otherwise, remove the Pipfile.lock and redo the above command.

• Enter the virtual environment by pipenv shell
• Run mote -h to see the help message

Usage

usage: mote [-h] [-v version] [-c CONFIG] [--model MODEL]
            {join,app,pull,mac,rejoin,info,abp,create} ...

Tool to emulate LoRa mote (a.k.a end-device) and Gateway, supported command
list: ['join', 'app', 'pull', 'mac', 'rejoin', 'info', 'abp', 'create']

optional arguments:
  -h, --help            show this help message and exit
  -v version, --version version
                        Choose LoRaWAN version, 1.0.2 or 1.1(default)
  -c CONFIG, --config CONFIG
                        Specify the directory of config files, default
                        './config'
  --model MODEL         Specify the directory to save the model file, default
                        './models'

Supported commands:
  {join,app,pull,mac,rejoin,info,abp,create}
    join                Send join request.
    app                 Send application data.
    pull                Send PULL_DATA.
    mac                 Send MACCommand.
    rejoin              Send rejoin request.
    info                Show information of current mote.
    abp                 Initialize mote in ABP mode.
    create              Handle configurations.

Tutorial

• First, we need to create configuration files by command mote create [-c ./config]. Mote will generate required config template JSON files in the ./config directory (default). In the directory, several JSON config files are included.
• config.json: Basic configurations.
• gateway.json: Gateway EUI.
• device.json: Device parameters for OTAA mode.
• abp.json: Device parameters for ABP mode.

OTAA

• Modify device infomation in device.json copied. An example: :

  {
      "Device": {
          "JoinEUI": "0000000000000000",
          "DevEUI": "0000000000000000"
      },
      "RootKeys": {
          "AppKey": "00000000000000000000000000000000",
          "NwkKey": "00000000000000000000000000000000"
      }
  }

NOTE: If you want to emulate LoRaWAN 1.0 device, first set JoinEUI equal to AppEUI and set NwkKey equal to AppKey.

ABP

• Modify device activation information in abp.json. An example: :

  {
      "deveui": "0000000000000000",
      "joineui": "0000000000000000",
      "devaddr": "00000000",
      "appkey": "00000000000000000000000000000000",
      "nwkkey": "00000000000000000000000000000000",
      "nwksenckey": "00000000000000000000000000000000",
      "snwksintkey": "00000000000000000000000000000000",
      "fnwksintkey": "00000000000000000000000000000000",
      "appskey": "00000000000000000000000000000000",
      "fcntup": 0,
      "version": "1.1"
  }

• Currently, five kinds of message is supported: pull data, join request, rejoin request, confirmed (or unconfirmed) data up (with or without FOpts) and MAC Commands in FRMPayload field:

NOTE: Always remember to mote pull to keep the gateway alive in server.

mote info
mote pull
mote abp
mote join [-n]
mote rejoin 'rejointyp' (0, 1, 2)
mote app 'message' (uplink message, will be encoded by UTF-8) [-auf]
mote mac 'command' (MAC Commands in FRMPayload field)

Here is the example step of interaction with ChirpStack:

mote pull
mote join -n
mote app helloworld -f 0302
mote main.py mac 0302
