Chirpstack V3 Network Server configuration for AS_923_4

I need some help configuring the network server for AS_923_4 (i.e. 917-920). This is what I have so far. What else am I missing?

# See for a full
# configuration example and documentation.
# This file is for the AS_923_4 band. See the examples/ folder for more
# configuration examples.


servers=[ "servername1:6378", "servernam2:6378" ]

# Database index.
# By default, this can be a number between 0-15.

# Redis Cluster.
# Set this to true when the provided URLs are pointing to a Redis Cluster
# instance.

# Master name.
# Set the master name when the provided URLs are pointing to a Redis Sentinel
# instance.

# Connection pool size.
# Default (when set to 0) is 10 connections per every CPU.

# TLS enabled.
# Note: this will enable TLS, but it will not validate the certificate
# used by the server.



enabled_uplink_channels=[1, 2, 3, 4, 5, 6]

# Event topic template.

    # Command topic template.
    # Use:
    #   * "{{ .GatewayID }}" as an substitution for the LoRa gateway ID
    #   * "{{ .CommandType }}" as an substitution for the command type
    command_topic_template="as923_4/gateway/{{ .GatewayID }}/command/{{ .CommandType }}"


You need to configure a gateway bridge to receive messages from your AS923-4 gateways and to use this topic prefix (which contains “as923_4”).

It is also perhaps necessary to configure the uplink channels that Chirpstack shall inform your devices of, otherwise the devices will only work with the default channels. See the blocks of this part of the documentation: Configuration - ChirpStack open-source LoRaWAN® Network Server documentation

Thank you for your feedback. I’m aware of the GW bridge config and already done it once for eu868. I’m just looking for NS 923_4 example configurations people have already tested.

Hi @HaimL, here you can find the list of band names:

It should be set to AS923-4.

enabled_uplink_channels=[1, 2, 3, 4, 5, 6]

This does not apply to the AS923 bands and you can remove this config. By default there are two channels active:

This can be extended in the same way as the EU868 region using the extra_channels option:

For the other AS23-4 related setting values (min/max DR, RX2 freq, etc…), you might want to take a look at the AS923-4 config file that is shipped with ChirpStack v4:
