This utility allows you to sniff LoRa networks with an RNode, and dump captured packets to the console or files.
usage: loramon [-h] [-C] [-W directory] [--freq Hz] [--bw Hz] [--txp dBm]
[--sf factor] [--cr rate]
[port]
LoRa packet sniffer for RNode hardware.
positional arguments:
port Serial port where RNode is attached
optional arguments:
-h, --help show this help message and exit
-C, --console Print captured packets to the console
-W directory Write captured packets to a directory
--freq Hz Frequency in Hz
--bw Hz Bandwidth in Hze
--txp dBm TX power in dBm
--sf factor Spreading factor
--cr rate Coding rateIf you already have Python3 and pip installed, you can easily install LoRaMon through pip:
pip3 install loramonIf you want to install directly from this repository, first install the dependencies:
sudo apt install python3 python3-pip
sudo pip3 install pyserialAnd then clone the repository and make LoRaMon executable:
git clone https://github.com/markqvist/LoRaMon.git
cd LoRaMon
chmod a+x loramon
./loramon --helpListens on a specified frequency and displays captured packets in the console.
loramon /dev/ttyUSB0 --freq 868000000 --bw 125000 --sf 7 --cr 5 -CLike above, but also writes all captured packets individually to a specified directory.
loramon /dev/ttyUSB0 --freq 868000000 --bw 125000 --sf 7 --cr 5 -C -W capturedirIf you want to sniff LoRa packets with implicit header mode, use the --implicit option along with the length in bytes of the expected packet. This mode needs an RNode with a firmware version of at least 1.17.
loramon /dev/ttyUSB0 --freq 868000000 --bw 125000 --sf 7 --cr 5 -C -W capturedir --implicit 12
