• two standard RJ45 ethernet cables: one from the network to the PoE injector, and one from the PoE injector to the station. Detailed instructions are available in the LoRa station Installation and Maintenance guide available on the Documentations page.

• WIRGRID debug tool (access to linux console)

Connect the debug tool on the station front :
PC Drivers are available at ftdi drivers
-Debug probe BOOT button is not used on LoRA Station
-Debug probe RESET button triggers a hard reset

• USB wire (A type <> B type) to connect debug probe to PC

• PoE injector (class 1, 48V) or DC power supply (10V to 30V).

To ensure the LoRa IoT Station is started up press the test button and check the POWER STATION LED is ON. Leds are enabled during a minute.

• firstly connect the debug tool to the station and to the PC : open a serial terminal on PC (typically HyperTerminal application on Windows) on the com port created by FTDI driver with the following standard parameters :

  baudrate : 115200
  data length : 8
  parity : none
  stop bit : 1
  flow control : none

• after getting prompt : enter login “root” with password “root”.

• PC Ethernet wire can be connected to the PoE power supply unit or directly to the station USB connector using an USB/NET adaptor. Then, start an ssh client (typically Putty on Windows) on port 22 and using the station “out of the box” default IP address which is 192.168.4.155. The PC ethernet address must have been previously configured in the same LAN (192.168.4.150 for example).
• after getting prompt : enter login “root” with password “root”.

Check the firmware version of your LoRa Station.
Kerlink released an improved LoRa Station (so called 27dBm) starting from May 2015. This hardware update implied a Firmware update: kernel update, SDK update, and Semtech's LoRa-HAL specific compilation flags. This new firmware is labelled wirmaV2_wirgrid_v2.1.
Reference to this firmware is noted “Firmwave v2.x” in the wiki, the previous versions (only compatible with 20dBm boards) are noted “Firmware v1.x”.
The firmware v2.x is fully compatible with older (20dBm) LoRA IoT Stations.

Get the firmware version of your LoRa Station with the command “get_version -u”
The firmware version is after the field PROD_FW=

On Firmware v1.x, several binaries are installed on the LoRa Station filesystem based on the Semtech examples (from github:lora_gateway).

• Go to the path /mnt/fsuser-1/test_hal_v1.5.0_868Mhz

Read the readme.md files to learn how to use them.

Install the ready-to-use “packet forwarder” on the gateway and see your End Point on the semtech demonstration server.
Firmware V2.x:

• Delivered without pre-installed binaries, download and intall them from : firmware_v2.x test_applications
• Test applications are built with LoRa MAC layer activated by default.
• LoRa Mote provided with this firmware can be configured thanks to a PC tool: LoRa Mote configuration page
• Packet forwarder for Kerlink LoRa Station is available here: packet forwarder

Firmware v1.x:

• Follow the link demo_lora_packet_forwarderready-to-use_package
• Lora MAC layer not activated by default (test apps and LoRa Motes).

Compile the Semtech's HAL and test binaries.

• Follow the link configuration

build your own kernel and rootfs

• Follow the link Distribution

Install the IBM/LRSC-ready firmware and register your LoRa Station to the IBM/LRSC network:

• Follow the direct link https://lrsc.ch/ssc/kerlink.html and contact LRSC team at lrsc@zurich.ibm.com

Kerlink is a member of LoRa Alliance and the Kerlink gateway is compatible with LoRaWAN protocol. If you need information about LoRaWAN network protocol please contact the LoRa Alliance and request LoRaWAN specification : http://www.lora-alliance.org/For-Developers/LoRaWANDevelopers
