uint8_t[2]data3

Detailed Description ​

cpp
struct ble_uuid128_t;

Structure to convey information about UUIDs in BLE.

By definition BLE UUIDs are always 'reversed'. For example the following UUID { 77880001-d229-11e4-8689-0004a5d5c51b } would be represented in ble_uuid128_t format as follows:

cpp
ble_uuid128_t my_uuid = {
   .data1 = {0x1b, 0xc5, 0xd5, 0xa5},
   .data2 = {0x04, 0x00},
   .data3 = {0x89, 0x86},
   .data4 = {0xe4, 0x11, 0x29, 0xd2, 0x01, 0x00, 0x88, 0x77}
 }
