Hi!  
I am newbie here, but interested in lora techologies few years ago.  
Sorry for my english 🙂  
I registered a raspberry zero+ic880a gateway but based on the old V2 version.  
Not worked, so i delete the gateway, registered a new but can not use the old, default gateway id. (eui-xxx…)  
I prepare my gateway with the newer Station Basic software (follow this instructions: [[Bulding a gateway with Raspberry Pi and IC880A | The Things Stack for LoRaWAN](https://www.thethingsindustries.com/docs/gateways/raspberry-pi/)]), but continuosly break the connection with server, because of the built in euiprefix, what is eui-. My new gateway id is ksanci-_myeui_.  
How can i change the prefix from built in eui- (::1) to ksanci-?  
I hope anybody understood my problem 😃  
Or the problem is completely different?  
Thanks!

Will close the thread but for the record for anyone else finding this later V2 is gone and there is no connection to V3 if deleted in V2 then there is no restriction of re-use in V3. If deleted in V3 then the EUI can be re-used but the GW-ID cannot and a new one (free form text!) will be required.

Meets this need hence now connected 🙂
