Extra channel for AS923

Hi,

I would like to understand how extra channel works.
I’m using AS923. the netowrk configuration as follows:

[network_server.band]
name=“AS923”

#LoRaWAN network related settings.
[network_server.network_settings]

# Extra channel configuration.
#
# Use this for LoRaWAN regions where it is possible to extend the by default
# available channels with additional channels (e.g. the EU band).
# The first 5 channels will be configured as part of the OTAA join-response
# (using the CFList field).
# The other channels (or channel / data-rate changes) will be (re)configured
# using the NewChannelReq mac-command.
#
[[network_server.network_settings.extra_channels]]
frequency=922100000
min_dr=0
max_dr=5

[[network_server.network_settings.extra_channels]]
frequency=922400000
min_dr=0
max_dr=5

[[network_server.network_settings.extra_channels]]
frequency=922600000
min_dr=0
max_dr=5

[[network_server.network_settings.extra_channels]]
frequency=923000000
min_dr=0
max_dr=5

[[network_server.network_settings.extra_channels]]
frequency=923600000
min_dr=0
max_dr=5

[[network_server.network_settings.extra_channels]]
frequency=921900000
min_dr=6
max_dr=6

[[network_server.network_settings.extra_channels]]
frequency=923850000
min_dr=7
max_dr=7

However, after the device joins, the frequency plan set in the device does not contain frequency 923.4 MHz. Why is it not included? isnt this one of the default AS923 frequencies?

Did you add extra channels inside gateway-profiles of ChirpStack?
