I built a single Channel gateway and tried to register it. I only had the gateway ID, but not the DEV EUI. It registered, but no data came in. So i deleted the gateway to register it again, but I couldn’t as I was told, that the ID is already present. What can I do to re-register the gateway ? ---

You don’t. TTN does not support Single Channel Packet Forwarders as they are disruptive to the community network. Please see: > [@Single Channel Packet Forwarders (SCPF) are obsolete and not supported](https://www.thethingsnetwork.org/forum/t/single-channel-packet-forwarders-scpf-are-obsolete-and-not-supported/31117): > > Single channel packet forwarders are obsolete and are not supported Single Channel in this article refers to both Single Channel and Dual Channel devices (and any variations thereof). Single Channel Packet Forwarders are not LoRaWAN compliant gateways. They negatively impact proper operation of gateways and end devices (nodes) in their area which means they negatively impact The Things Network and its users, but they also impact other LoRaWAN operators.
