Change the bluetooth device name

I have a fenix 7 and use Bose sport earbuds. When the earbuds try to pair, they are looking for a device named "REDPINE_GATT_V02" which takes forever because each single character is spelled because it is uppercase. With my Forerunner 945 it was only "watch". I couldn't find any place to change this. This is not the "nickname" I gave my watch in Garmin Express / Connect. I searched several FIT-files on the watch for this text but couldn't find it. I can't change this name in the Bose App neither. I think this is the bluetooth broadcast name of my watch. On a PC I would change it in the bluetooth settings but I don't know where to change it for my fenix 7.



Thanks in advance
