Hi Brocaar,
Assume enabled_uplink_channels = [0,1,…14,15], and GW1 used 0~7, GW2 used 8~15, and GW1 located in City A, GW located in City B.
After NS received one uplink message, assume enabled ADR funciton, then NS will send LinkADRReq command in downlink message. If one end device under GW1, received such command, will enable channel 0~15, but GW1 could not listen channel 8~15, correct?
I think the key point is one NS just have one channel mask, up to 16 channels.
Thanks
