Common Packet Forwarder: installation and configuration

How to install the Common Packet Forwarder?

  1. Choose the packet forwarder to install from the resource page. Choosing the latest version of the packet forwarder is recommended.
  2. Download the “lorad” and “lorafwd” .ipk packages files.
  3. Install the .ipk files using the instructions of the software updates page. Packages can be installed simultaneously.

The CPF installation on a Wirnet iBTS takes some time since the FPGA is updated during this process. Expect approximately 15 to 30 minutes, depending on the number of connected modems.

The installation of the “lorad” and “lorafwd” packages adds the following files on the system:

How to configure and monitor the packet forwarder?

The configuration is achieved in 3 steps:

  • lorad configuration
  • lorafwd configuration
  • monitoring and auto-start configuration

lorad configuration

The goal of the lorad configuration is to define the frequency plan that will be used to receive packets from the end-devices, to enable the LBT feature and configure the class B beacons.

  • A few frequency plan templates are pre-installed on the gateway (under /user/etc/lorad): choose the one that suits the most your requirement.
  • Edit /etc/default/lorad and make sure that the CONFIGURATION_FILE field links to the template you previously chose.
  • Edit the template you chose to adapt it to your needs. Since the hardware of Wirnet iBTS and Wirnet iFemtoCell gateways is different, the configuration on each gateway differs (although it is quite similar).

iBTS

Wirnet iFemtoCell

lorafwd configuration

The goal of the lorafwd configuration is mainly to define to which LNS LoRa packets will be forwarded to.

  • Edit /user/etc/lorafwd/lorafwd.toml. This configuration file is formatted using the TOML v0.5.0 language:
    • Most keys are pre-configured with correct values.
    • The description of each key is directly written in the configuration file.
    • Hereunder are the keys that must changed to chose your LNS:
      • gwmp.node = “localhost”: The address of the LNS.
      • gwmp.service.uplink = 20000: The uplink port of the LNS.
      • gwmp.service.downlink = 20000 : The downlink port of the LNS.

Monitoring and auto-start configuration

By default, both lorad and lorafwd are started at boot time. If for some reason, one of the daemons stops, it will be automatically restarted by monit.

  • The autostart behavior is handled by the symlinks /etc/rcU.d/S50lorad and /etc/rcU.d/S51lorafwd.
  • The monitoring behavior is handled by the /etc/monit.d/lorad and /etc/monit.d/lorafwd files.

The daemons can be started/stopped/rebooted and monitored with monit. See monit page for more details.

Both daemons are independent. If one is stopped/restarted, the other one does not need to be stopped/restarted.

Log management

Both daemons generates logs in the /var/log/lora.log* files.

The verbosity of the daemons can be increased using the EXTRA_ARGS field under /etc/default/loradand /etc/default/lorafwd.

lorad:

  • NOTICE = -v: displays start and stop traces
  • INFO = -vv:
    • Displays the configuration of the hardware (frequencies, bandwidth, spreading factor, antenna, LBT, …)
    • Displays the number of uplinks and beacons sent.
    • Displays TAI/PPS info
  • DEBUG = -vvv: Displays the hexdump of the packets

lorafwd:

  • NOTICE = -v: displays start and stop traces
  • INFO = -vv:
    • Displays the configuration of the forwarder (gateway ID, LNS, uplink/downlink port, GWMP configuration, …)
    • Displays the uplinks and downlink meta-data
    • Displays the acknowledge / heartbeat / drop traces
  • DEBUG = -vvv: Displays the hexdump of the packets
