If the loraserver sends a ADR_link request only the EU default channels are included? Why not the extra channels?
loraserver[12357]: time=“2019-07-10T10:14:46+02:00” level=info msg=“link_adr request acknowledged” dev_eui=0600f9ff54ceab31 dr=5 enabled_channels="[0 1 2]" nb_trans=3 tx_power_idx=5
The devices use then only the 3 default channels even they learned before the “extra channels” via NewChannel request.
Could you post your configuration? The following works fine for me:
# 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.
# Note: when left blank, all channels will be enabled.
#
# Example:
# enabled_uplink_channels=[0, 1, 2, 3, 4, 5, 6, 7]
enabled_uplink_channels=[]
# 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.
#
# Example:
[[network_server.network_settings.extra_channels]]
frequency=867100000
min_dr=0
max_dr=5

(The ACK was for the previous LinkADRReq which requested tx_power_idx=1, that is why it does not match the screenshot.)

There you go! Just leave that blank for the EU868 band. This is mostly used to reduce the number of channels (e.g. for the US band there are 72 and most of the times you only want to use 8 + 1 single SF).
ok, I will let it empty, and try again! Thanks
now it looks better!!

What is the reason that for some devices the NS sends still “enabled channels=[0 1 2]” ?
Does it depend if “NewChannelReq” was successfully for all extra channels?
