Thanks
Sorry for my english
We need you to provide some logs.
sudo systemctl stop ttn-gateway cd /opt/ttn-gateway/packet_forwarder/lora_pkt_fwd/sudo ./lora_pkt_fwd
@ZhuQI,
Thanks for your quick response I did the steps and here is the log
Thanks

Change 16 to 17 in the /opt/ttn-gateway/packet_forwarder/lora_pkt_fwd/global_conf.json file and see if the issue is resolved.
I think maybe ttn modified the request-accept power in the us915 band. Power 17 is not in the downlink power list, so the gateway rejected the request-accept.
We have fixed this issue in the next version of the gateway firmware. When the power is not in the power list, the gateway will send using the nearest smaller power.
Thank you very much.
We are very glad that you have chosen RAK and hope that RAK will bring you a better experience.
