I try to configure extra channels: 8 channels from 867,1 to 868,5 are working fine.
But the GW offers 16 channels, additional from 863,1 to 864,5 MHz. If I try add one of the second eight channels I always get following warning from the loraserver:
This (mac-command) is returned by the device, you can also inspect this in the LoRaWAN frame-logs of the device. LoRa Server asks the device to configure an additional channel but the device rejects this channel. You would have to look into the device firmware source or ask the device vendor why the device is rejecting this mac-command.
I have seen if I enable second eight channels (in complete sum 16 channels) of the GW most of the sensors don’t accept it. And the other bad thing is ADR isn’t working any more!
