In Aranet4 FW >= v1.2.0 the advertised service UUID and the service UUID containing Aranet4 measurements has been changed:
Prior to FW v1.2.0 the service UUID is f0cd1400-95da-4f4b-9ac8-aa55d312af0c.
With FW v1.2.0 and newer the service UUID is 0000FCE0-0000-1000-8000-00805f9b34fb.
Advertised service uses Bluetooth assigned 16bit UUID = 0xFCE0.
For Bluetooth assigned UUIDs base is 0000xxxx-0000-1000-8000-00805F9B34FB.
So 16bit UUID 0xFCE0 in 128bit format looks like 0000FCE0-0000-1000-8000-00805F9B34FB.
Service also uses 16bit UUID = 0xFCE0 (0000FCE0-0000-1000-8000-00805F9B34FB).
All custom Characteristics use the same previously used custom 128bit UUIDs f0cdXXXX-95da-4f4b-9ac8-aa55d312af0c.
