Deploying an End-to-End LoRaWAN Platform
Starting from September 2016, Saint-Joseph University of Beirut (USJ) will be deploying the first academic LoRa network in Lebanon. The network will support monitoring of micro-climate conditions in vineyards. Here below you can find a detailed description of the experimental platform implementing an end-to-end LoRaWAN solution.
-. End-nodes
-. Autonomo with LoRaBee
-. Arduino with Dragino Shield
-. Gateways
-. Single Channel Gateway
The single channel gateway includes a LoRa transmission module (Dragino Shield) connected to a Raspberry Pi (2 or 3) as shown in Figure 1. Communication between the two modules is done over an SPI interface.
In order to assemble the gateway, start by making the wire connections: the connection pins are identified in Figures 2 and 3.
Connect the Raspberry Pi to the Internet and install the packet forwarding software. The source code of the single channel packet forwarder is available on: https://github.com/samerlahoud/single_chan_pkt_fwd. In order to install it, you need to:
- Enable SPI on the Raspberry Pi using raspi-config
- Download and unzip the source code:
wget https://github.com/hallard/single_chan_pkt_fwd/archive/master.zip unzip master.zip
- Install the wiring library:
apt-get update apt-get install wiring
Now you can compile and run the packet forwarder as root.
make all nohup ./single_chan_pkt_fwd &
