Introduction

This project mainly simulates a gateway and devices in a LoRaWAN network communication environment, with ChirpStack serving as the network server. A local UDP client is used to handle communication with the ChirpStack network.

Setup

Working configuration

Ubuntu 20.04 LTS Python 3.8

config

/config

• config.json: Basic configurations.
• gateway.json: Gateway EUI.
• device.json: Device parameters for OTAA mode.

（These have to be the same as the information related to the devices registered inside ChirpStack）

OTAA Modify device infomation in config/device.json. An example:

{
    "Device": {
        "JoinEUI": "0000000000000001",
        "DevEUI": "bfd2718a2904e6a8"
    },
    "RootKeys": {
        "AppKey": "5871FE1C02D1A74B6684D2D9FF54CEDA",
        "NwkKey": "14714AAFF51F7792D8C4CCB614D08396"
    }
}

Gateway

Modify Gateway infomation in config/gateway.json. An example:

{"GatewayEUI": "4e7b2799b9bfd427"}

Steps

The general workflow is as follows:

1. Send a PULL_DATA to ChirpStack server by python main.py pull.
2. Send a join request message to ChirpStack server by python main.py join.
3. If the join accept message is decoded successfully, we can send an uplink message.
4. An Uplink message can be sent by python main.py app -m xxxxx.

1. Pull_data

python main.py pull

2. Join_request

python main.py join -n / python main.py join

3. Send_data

python main.py app test

4. Results

5. Fuzzingtest

Currently, only the mutation construction of data sent to the Device has been implemented.

python main.py fuzz testdata
