Network-server management

Network-servers

LoRa App Server is able to connect to one or multiple LoRa Server network-server instances. Global admin users are able to add new network-servers to the LoRa App Server installation.

Note: once a network-server is assigned to a service-profile or device-profile, a network-server can’t be removed before deleting these entities, it will return an error.

Routing-profile

When creating a new network-server, LoRa App Server will create a routing-profile on the given network-server, containing the hostname:ip of the LoRa App Server installation. In case your LoRa App Server installation is not reachable on localhost, make sure this hostname:ip is configured correctly in your configuration. This routing-profile is updated on network-server updates and deleted on network-server deletes.

TLS certificates

Depending the configuration of LoRa Server and LoRa App Server, you must enter the CA and client certificates in order to let LoRa App Server connect to LoRa Server and in order to let LoRa Server connect to LoRa App Server (see Routing-profile above).

Note that for security reasons, the TLS key content is not displayed when editing an existing network-server. Re-submitting does not clear the stored TLS key when left blank! The TLS key content will only be cleared internally when submitting a form with an empty TLS certificate value.

LoRa Server API is using TLS

You must enter the CA and TLS certificate fields under Certificates for LoRa App Server to LoRa Server connection.

Gateway-profiles

Once a network-server has been created, it is possible to provision one or more gateway-profiles on this network-server (available under the Gateway-profiles tab). When adding a gateway, it is then possible to select one of these gateway-profiles to make sure the gateway configuration is in sync with the channels used by the network.

Please note that this must also be configured in your LoRa Gateway Bridge configuration.

Important: changing the channel-plan of the gateway does not change the channels used by the devices. For a correct setup, the gateway-profile(s) must at least support the channels used by your devices. The channels that must be used by your devices must be configured in your LoRa Server configuration.

Enabled channels

Enter the list of default channels that you would like to use for this gateway-profile. Note that these are the channels that are specified by the LoRaWAN Regional Parameters.

Extra channels

If allowed by your LoRaWAN region, you can use Add extra channel to configure additional channels that are not defined by the LoRaWAN Regional Parameters.

Hardware limitations

This feature is limited to 8-channel gateways (currently) and assumes that channels can be distributed over two radios. When defining a channel-plan, please keep in mind that the channels fit within the bandwidth of two radios.

The bandwidth of each radio depends on the bandwidth of the assigned channels:

  • 500kHz channel = 1.1MHz radio bandwidth
  • 250kHz channel = 1Mhz radio bandwidth
  • 125kHz channel = 0.925MHz radio bandwidth
