FloraNet is a LoRaWAN™ Network Server.
In a LoRaWAN network, the Network Server (NS) is a central element that communicates to end-devices via gateways, which act as transparent bridges between a LoRa™ wireless network and an enterprise IP network.
FloraNet was developed to promote development, prototyping and learning of IoT concepts and technologies. Note that you should not consider FloraNet to be a production-ready system.
FloraNet was built using Python 2.7 and has been tested on Mac OS X and Ubuntu Linux platforms. It currently supports Multitech Conduit gateways and Multitech mDot 915 MHz RF modules (MTDOT-915) as end-devices.
- Supports Class A and Class C end-devices.
- Supports US 902-928 MHz and AU 915-928 MHz ISM bands.
- Support for over the air (OTA) activation and activation by personalisation (ABP) join procedures.
- Support for adaptive data rate (ADR) control.
- De-duplication of messages delivered from multiple gateways.
- Support for multiple applications and extensible application server interfaces using plugin modules.
- No support for CN779-787 or EU433 frequency bands.
- No support for Class B end-devices.
- support for EU863-870 at alpha stage
- Python 2.7
- Postgres 9.3+
- CryptoPlus 1.0
Installing CryptoPlus:
$ git clone https://github.com/doegox/python-cryptoplus.git
$ cd python-cryptoplus && sudo python setup.py install
Clone the repository:
$ git clone https://github.com/Fluent-networks/floranet.git
Run setup.py:
$ sudo python setup.py install
FloraNet uses a Postgres database to create ABP and OTA device information and maintain device state. The database connection assumes that the username/password is postgres/postgres and the database name is floranet. If you wish to alter this setup, edit the following line in the file data/alembic.ini:
sqlalchemy.url = postgresql://postgres:[email protected]:5432/floranet
Run alembic to perform the inital database migration to create the device table.
$ cd data
$ alembic upgrade head
You may want to populate the device table with ABP devices. This is accomplished using the devices.csv file in the seed directory. This file can be used to create ABP devices using by defining the following fields (one line per device):
| Field | Description | Data Type |
|---|---|---|
| deveui | Device EUI | Numeric |
| devaddr | Device address | Integer |
| appeui | Application EUI | Numeric |
| nwkskey | Network Secret Key | Numeric |
| appskey | Application Secret Key | Numeric |
Note that this file includes three sample devices. To seed the database device table, run the seeder script in the seed directory.
$ cd data/seed
$ ./seeder -s
To clear the device table, run:
$ ./seeder -c
FloraNet uses a text-based file compatible with Python's configuration file parser. The default configuration file default.cfg is located in the floranet directory. It contains the following sections:
[server]: defines the server network configuration, database connection, frequency band, OTA addressing, gateways and other parameters.[application.test]: defines an application identified bytest, including the application identifier (AppEUI), secret key (AppKey), and upstream application interface configuration.
Start FloraNet using the following command-line parameters.
floranet.py [-h] [-f] [-c config] [-l logfile]
Arguments:
-h, --help show help message and exit
-f run in foreground, log to console
-c config configuration file (default: default.cfg)
-l logfile log file (default: /tmp/floranet.log)
If you encounter an error "FATAL: password authentication failed for user postgres" at setup, you can change the password by:
>sudo -u postgres psql
postgres=# ALTER USER postgres PASSWORD 'postgres';
postgres=# CREATE DATABASE floranet;
