Channel Mask. How to configure it?

Dear tech supporters!
I’m testing LoRa Server (2.3.0). The problem is the following: When using ADR my Lora-server applies to the nodes a Channel Mask, which turns off all the channels except 2 first (0 and 1). And that is not what I want. I use RU_864_870 frequensies, but after recieving the cannel Mask the nodes start to use only 2 frequensies. How can I fix it?

Look in loraserver’s loraserver.toml configuration file. You should see the following line:

enabled_uplink_channels=[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]

This is how you adjust the channels being used.
