Conduit AEP: Convert to Basic Packet Forwarder


This section describes using LoRa Packet Forwarder Mode.

If you are using Cellular as WAN:

  • Before activating this mode, change the keep alive interval to 1 second within the Packet Forwarder application (keepalive_interval in the config file). This decreases the latency of packets over the radio enough to allow the return packet from the network server to get to the lora radio before its timestamp expires.
  • Excellent signal strength is also required to keep latency low enough for this mode to work.

To activate LoRa Packet Forwarder Mode:

  1. Under LoRaWAN > Network Settings,  select PACKET FORWARDER  under Mode. For details, see LoRaWAN Network Settings.
  2.  In the Config text field, enter the contents of your custom global_conf.json file.
  3. basic_pkt_fwd runs unless fake_gps parameters are included, in which case gps_pkt_fwd runs (for location use ref_latitude, ref_longitude and ref_altitude settings).
  4. Verify that the text field contents match the proper json format. Click Submit.
    •  The GUI passes the .json file to the packet forwarder application.
    •  If successful, a message displays LoRa settings successfully updated.
    •  If the format is incorrect, a message displays Invalid JSON input.
