+During this challenge, you will benefit from the first experimental platform implementing an end-to-end LoRaWAN solution in Lebanon. The platform consists of the following elements:
   * Devices that communicate to one or more gateways via a wireless interface using single hop LoRa and implementing the LoRaWAN protocol. These devices are physically connected to sensors that generate data.

 ===== -. Devices =====
-==== -. PC Configuration ====
 In orde to program the LoRaWAN devices, you should verify the installation one your PC of the following software:
   * Arduino IDE
   * LMIC Library
-==== -. Arduino with Dragino Shield ====
-=== -. Periodic Message Sending ===
 Devices in the LoRaWAN platform are implemented on Arduino boards with Dragino shields. The combined module as well as the basic configuration steps are presented in [[simple_lora_prototype|Simple Prototype of LoRa Communications]]. You can download the following sketch {{ :test-loraserver-comb-loraserver-dragino.zip |}} and modify it according to your preferences. Below you can find somme commented extracts of the sketch.

 You can also find another example of sketch to download: {{ :test-loraserver-moisture-on-move.ino.zip |}}. Here the message sending is not periodic but related to an event. For example, an infrared sensor detects a movement and triggers a signal for the device to send a LoRaWAN message. Note also that the join method used in this second sketch is Activation by Personalisation (ABP): the device address, the network session key, and the application session key are directly configured on the device.
-===== -. 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 2. 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 3 and 4.

-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:
-<code bash>
-wget https://github.com/hallard/single_chan_pkt_fwd/archive/master.zip
-unzip master.zip
-</code>
-  * Install the wiring library:
-<code bash>
-apt-get update
-apt-get install wiring
-</code>
-Compile the packet forwarder:
-<code bash>
-make all
-</code>
-For gcc version 4.6.3, a compilation error results in the following warning ''unrecognized command line option '-std=c++11'''. Replace ''-std=c++11'' by ''-std=c++0x'' in the Makefile and recompile:
-<code>
-CFLAGS = -std=c++0x -c -Wall -I include/
-</code>
-Now, you need to configure the single channel packet forwarder. This is done in the {{ :global_config.json.zip |}} configuration file. Particularly, you need to choose the channel, the spreading factor, the pins for SPI communication, and the address of the backend server. Note that you can specify multiple backends for testing purposes.
-Finally, you can run the packet forwarder as root!
-<code bash>
-nohup ./single_chan_pkt_fwd &
