Unique ID for registering on TTN

How do I get the unique ID for the HT-M00 to register it to TTN? I don’t want to erase by downloading the CHIP-ID program?

hi,

For now, the Gateway ID cannot be modified. The Gateway ID is automatically generated based on the MAC address of the M00 internal network card.
