Also in one of Nordic examples I can see this: #define LBS_UUID_BASE {0x23, 0xD1, 0xBC, 0xEA, 0x5F, 0x78, 0x23, 0x15, 0xDE, 0xEF, 0x12, 0x12, 0x00, 0x00, 0x00, 0x00} #define LBS_UUID_SERVICE 0x1523 #define LBS_UUID_LED_CHAR. Each descriptor is a two-element tuple containing a UUID and a flags value. GATT Services are collections of characteristics and relationships to other services that encapsulate the behavior of part of a device. The configuration is stored in flash memory. Characteristic I/O (Read/Write) and Known Transparent (UART. Below is a screenshot from the Bluetooth-SIG official website showing some of the standard UUIDs used for Characteristics. The 128-bit vendor-specific UUID of the Nordic UART Service is 6E400001-B5A3-F393-E0A9-E50E24DCCA9E (16-bit offset: 0x0001). 667 | ISO/IEC 9834-8, a UUID is either guaranteed to be different from all other UUIDs generated before 3603 A.
