Update of 29th August, 2017
|
||||
---------------------------
|
||||
|
||||
I'm happy to announce that as of ```gr-lora``` version 0.6, a new clock recovery algorithm has been implemented which fixes previous issues with long LoRa messages. Other components, such as whitening, detection and decoding have been improved as well (see the Git log for more details). Given a clear signal, the decoding accuracy is now close to 100% for all SFs, and I therefore consider LoRa fully reverse engineered. Future updates will focus on improving the performance and minor details of the specification.

Usage
|
||||
-----
|
||||
|
||||
See the LICENSE file and top of the source files for the license of this project. If you are working on a research topic or project that involves the usage of ```gr-lora``` or its algorithms, we would appreciate it if you could acknowledge us. We are currently working on a full writeup of the decoder, but in the meantime, you can cite this repository as follows:

Features
|
||||
--------
|
||||
## Features
|
||||
|
||||
All features of the LoRa physical-layer modulation scheme are described in various patents and blog posts (for a good resource, see [this RevSpace page](https://revspace.nl/DecodingLora)). ```gr-lora``` supports most of these features, except for:
|
||||
|
||||
- CRC checks of the payload and header
|
||||
- Decoding multiple channels simultaneously
|
||||
|
||||
This library was primarily tested with a USRP B201 as receiver and Microchip RN2483 as transmitter. If you encounter an issue with your particular setup, feel free to let me know in the Issues section of this repository.

Installation
|
||||
------------
|
||||
### Update of 29th August, 2017
|
||||
|
||||
The following dependencies are required:
|
||||
- numpy
|
||||
- scipy
|
||||
- log4cpp
|
||||
- [liquid-dsp](https://github.com/jgaeddert/liquid-dsp)

|

|
||||
|

The installation procedure is the same as for any GNURadio OOT module:

|
||||
|
||||
|
||||
## Installation
|
||||
|
||||
Installing `gr-lora` is possible in two ways: either by downloading the Docker container, which contains all dependencies and `gr-lora` packaged in a single container, or by manual installation.
|
||||
|
||||
### Docker installation
|
||||
|
||||
To avoid installation errors and cluttering your system with the required dependencies, the best approach to install `gr-lora` is through a Docker container. Make sure the `docker` service is running, then perform the following steps:
|
||||
|
||||
```
|
||||
git clone https://github.com/rpp0/gr-lora.git .
|
||||
cd docker/
|
||||
./docker_run_grlora.sh
|
||||
```
|
||||
|
||||
The `docker_run_grlora.sh` script will download the Docker container and run it in 'privileged' mode (in order to access your SDR over USB). After that, you should get a shell inside the container:
|
||||
|
||||
```
|
||||
[root@5773ed19d95d apps]#
|
||||
```
|
||||
|
||||
See the 'Testing' section below for examples on how to use `gr-lora`.
|
||||
|
||||
### Manual installation
|
||||
|
||||
If you prefer a manual installation, the following dependencies are required: `python2-numpy`, `python2-scipy`, `swig`, `cppunit`, `fftw`, `gnuradio`, `libvolk`, `log4cpp`, `cmake`, `wx`, and [`liquid-dsp`](https://github.com/jgaeddert/liquid-dsp).
|
||||
|
||||
The installation procedure is the same as for any GNU Radio OOT module:
|
||||
|
||||
```
|
||||
git clone https://github.com/rpp0/gr-lora.git .
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ../ # Note to Arch Linux users: add "-DCMAKE_INSTALL_PREFIX=/usr"
|
||||
make && sudo make install
|
||||
```
|
||||
|
||||
Testing
|
||||
-------
|
||||
## Testing and usage
|
||||
|
||||
To test your installation, you can download one of the sample LoRa signals at [rpp0/gr-lora-samples](https://github.com/rpp0/gr-lora-samples). Configure ```apps/lora_receive_file.py``` to use the sample and run the script. You should see the decoded sample data:

|

...
|

```
|
||||
|
||||
Alternatively, if you have a LoRa transmitter, you can configure/modify ```/examples/_examplify.py``` to generate example files and add them to ```/examples/qa_BasicTest_Data.xml``` to run them automatically with ```python/qa_BasicTest_XML.py``` (```xmltodict``` module needed). Note that this script should be run with its shell script in ```build/python```. This is to ensure compatibility with ```make test```.
|
||||
Alternatively, if you have a hardware LoRa transmitter, you use ```apps/lora_receive_realtime.py``` to decode signals in real time. If you have a Microchip RN2483, you can use [python-loranode](https://github.com/rpp0/python-loranode) to easily send messages via Python.
|
||||
|
||||
By default, decoded messages will be printed to the console output. However, you can use a `message_socket_sink` to forward messages to port 40868 over UDP. See the [tutorial](https://github.com/rpp0/gr-lora/wiki/Capturing-LoRa-signals-using-an-RTL-SDR-device) for more information.
