With my AS923 deployment i am only seeing 2 frequencies being used by my nodes - 923200000 and 923400000. The configuration documentation for the network-server states that extra channel configuration is only needed when support for additional channels (to the default) are required. My reading of the AS923 specification is that there are 8 default channels. Trying to follow the source code and looking in band_as923.go it appears only 2 default channels are defined? Assuming this was the case i tried to enter extra 6 channels of the regional spec using the [[network_server.network_settings.extra_channels]] configuration option. I then expected to see a CFLIST field generated in the join accept message for the node however it was not created (monitoring the lorawan dataframes for the node).
Is my interpretation right and i need to add the additional 6 channels to my configuration to use all the AS923 frequencies? If so why am i not seeing the CFLIST field in the JOIN ACCEPT message?
Thanks for any guidance on this.
