This is how the loraserver configuration is going to look like 
[general]
# Log level
#
# debug=5, info=4, warning=3, error=2, fatal=1, panic=0
log_level=4
# PostgreSQL settings.
#
# Please note that PostgreSQL 9.5+ is required.
[postgresql]
# PostgreSQL dsn (e.g.: postgres://user:password@hostname/database?sslmode=disable).
#
# Besides using an URL (e.g. 'postgres://user:password@hostname/database?sslmode=disable')
# it is also possible to use the following format:
# 'user=loraserver dbname=loraserver sslmode=disable'.
#
# The following connection parameters are supported:
#
# * dbname - The name of the database to connect to
# * user - The user to sign in as
# * password - The user's password
# * host - The host to connect to. Values that start with / are for unix domain sockets. (default is localhost)
# * port - The port to bind to. (default is 5432)
# * sslmode - Whether or not to use SSL (default is require, this is not the default for libpq)
# * fallback_application_name - An application_name to fall back to if one isn't provided.
# * connect_timeout - Maximum wait for connection, in seconds. Zero or not specified means wait indefinitely.
# * sslcert - Cert file location. The file must contain PEM encoded data.
# * sslkey - Key file location. The file must contain PEM encoded data.
# * sslrootcert - The location of the root certificate file. The file must contain PEM encoded data.
#
# Valid values for sslmode are:
#
# * disable - No SSL
# * require - Always SSL (skip verification)
# * verify-ca - Always SSL (verify that the certificate presented by the server was signed by a trusted CA)
# * verify-full - Always SSL (verify that the certification presented by the server was signed by a trusted CA and the server host name matches the one in the certificate)
dsn="postgres://localhost/loraserver_ns?sslmode=disable"
# Automatically apply database migrations.
#
# It is possible to apply the database-migrations by hand
# (see https://github.com/brocaar/loraserver/tree/master/migrations)
# or let LoRa App Server migrate to the latest state automatically, by using
# this setting. Make sure that you always make a backup when upgrading Lora
# App Server and / or applying migrations.
automigrate=true
# Redis settings
#
# Please note that Redis 2.6.0+ is required.
[redis]
# Redis url (e.g. redis://user:password@hostname/0)
#
# For more information about the Redis URL format, see:
# https://www.iana.org/assignments/uri-schemes/prov/redis

# Time to wait for uplink de-duplication.
#
# This is the time that LoRa Server will wait for other gateways to receive
# the same uplink frame. Valid units are 'ms' or 's'.
deduplication_delay="200ms"
# Device session expiration.
#
# The TTL value defines the time after which a device-session expires
# after no activity. Valid units are 'ms', 's', 'm', 'h'. Note that these
# values can be combined, e.g. '24h30m15s'.
# Please note that this value has influence on the uplink / downlink
# roundtrip time. Setting this value too high means LoRa Server will be
# unable to respond to the device within its receive-window.
device_session_ttl="744h0m0s"
# Get downlink data delay.
#
# This is the time that LoRa Server waits between forwarding data to the
# application-server and reading data from the queue. A higher value
# means that the application-server has more time to schedule a downlink
# queue item which can be processed within the same uplink / downlink
# transaction.
# Please note that this value has influence on the uplink / downlink
# roundtrip time. Setting this value too high means LoRa Server will be
# unable to respond to the device within its receive-window.

# LoRaWAN regional band configuration.
#
# Note that you might want to consult the LoRaWAN Regional Parameters
# specification for valid values that apply to your region.
# See: https://www.lora-alliance.org/lorawan-for-developers
[network_server.band]
# LoRaWAN band to use.
#
# Valid values are:
# * AS_923

# Enforce 400ms dwell time
#
# Some band configurations define the max payload size for both dwell-time
# limitation enabled as disabled (e.g. AS 923). In this case the
# dwell time setting must be set to enforce the max payload size
# given the dwell-time limitation. For band configuration where the dwell-time is
# always enforced, setting this flag is not required.
dwell_time_400ms=false
# Enforce repeater compatibility
#
# Most band configurations define the max payload size for both an optional
# repeater encapsulation layer as for setups where a repeater will never
# be used. The latter case increases the max payload size for some data-rates.
# In case a repeater might used, set this flag to true.
repeater_compatible=false
# LoRaWAN network related settings.
[network_server.network_settings]
# Installation margin (dB) used by the ADR engine.
#
# A higher number means that the network-server will keep more margin,
# resulting in a lower data-rate but decreasing the chance that the
# device gets disconnected because it is unable to reach one of the
# surrounded gateways.
installation_margin=10
# Class A RX1 delay
#
# 0=1sec, 1=1sec, ... 15=15sec. A higher value means LoRa Server has more
# time to respond to the device as the delay between the uplink and the
# first receive-window will be increased.
rx1_delay=1
# RX1 data-rate offset
#
# Please consult the LoRaWAN Regional Parameters specification for valid
# options of the configured network_server.band.name.

#
# Please consult the LoRaWAN Regional Parameters specification for valid
# options of the configured network_server.band.name.
rx2_dr=-1
# Enable only a given sub-set of channels
#
# Use this when ony a sub-set of the by default enabled channels are being
# used. For example when only using the first 8 channels of the US band.
#
# Example:
# enabled_uplink_channels=[0, 1, 2, 3, 4, 5, 6, 7]
enabled_uplink_channels=[]
# Extra channels to use for ISM bands that implement the CFList
#
# Use this for LoRaWAN regions where it is possible to extend the by default
# available channels with additional channels (e.g. the EU band).
# Note: the min_dr and max_dr are currently informative, but will be enforced
# in one of the next versions of LoRa Server!
#
# Example:
# [[network_server.network_settings.extra_channels]]
# frequency=867100000
# min_dr=0
# max_dr=5
# [[network_server.network_settings.extra_channels]]
