Set ChMaskCtrl to 6 instead of 0

ChirpStack Network Server
1

Hey there, how can I configure Chirpstack NS to set ChMaskCtrl value (on LinkAdrReeq) to 6 instead of 0? I’m using AS923-2 Freq Plan with additional custom freq that hardcoded on some nodes, but I don’t want to add this channel to others. Set ChMaskCtrl value to 6 (on AS923) is needed to make sure the node with additional freq use its preconfigured channels and also not bothering the channel’s configuration of the other nodes. Any help or alternative solution would be nice :smiley:. Thx.

When you have multiple channel-plans, I suggest setting up multiple ChirpStack Network Server instances, each with their different configs.
