BLE-CC2640R2F使用128bit UUID

LAUNCHXL-CC2640R2

说明：

以SimpleBLEPeripheral工程为例，说明如何使用自定义的128bit的UUID。

环境：

协议栈：simplelink_cc2640r2_sdk_1_50_00_58
仿真器：XDS110
编译软件：Code Composer Studio Version: 7.3.0.00019
硬件平台：LAUNCHXL-CC2640R2

UUID：

UUID(Universally Unique Identifier)是通用唯一识别码。 在蓝牙设备中，每个服务、特征值都有一个对应的UUID。 UUID是128bit的，但在CC2541、CC2640的协议栈中默认使用的是简短的16bit的UUID。代码中看起来是简短，实际上最终还是会补齐为128bit。 例如simpleGATTprofile服务的16bit的UUID是0xFFF0，特征值的16bit的UUID是0xFFF1~0xFFF5，它会被补齐为128bit

步骤：

1.修改PROFILE/simple_gatt_profile.h：

// Simple Profile Service UUID:03B80E5A-EDE8-4B33-A751-6CE34EC4C700
#define SIMPLEPROFILE_SERV_UUID                   0x00, 0xC7, 0xC4, 0x4E, 0xE3, 0x6C, 0x51, 0xA7, 0x33, 0x4B, 0xE8, 0xED, 0x5A,0x0E, 0xB8, 0x03

// Characteristic UUID:7772E5DB-3868-4112-A1A9-F2669D106BF3
#define SIMPLEPROFILE_CHAR_UUID                  0xF3, 0x6B, 0x10, 0x9D, 0x66, 0xF2, 0xA9, 0xA1, 0x12, 0x41, 0x68, 0x38, 0xDB,0xE5, 0x72, 0x77

2.修改PROFILE/simple_gatt_profile.c:

...
/*********************************************************************
 * GLOBAL VARIABLES
 */
// Simple GATT Profile Service UUID: 0xFFF0
CONST uint8 simpleProfileServUUID[ATT_UUID_SIZE] =
{
 SIMPLEPROFILE_SERV_UUID
};

// Characteristic 1 UUID: 0xFFF1
CONST uint8 simpleProfileCharUUID[ATT_UUID_SIZE] =
{
 SIMPLEPROFILE_CHAR_UUID
};
...
/*********************************************************************
 * LOCAL VARIABLES
 */
...
// Simple Profile Service attribute
static CONST gattAttrType_t simpleProfileService = { ATT_UUID_SIZE, simpleProfileServUUID };
...
/*********************************************************************
 * Profile Attributes - Table
 */
static gattAttribute_t simpleProfileAttrTbl[SERVAPP_NUM_ATTR_SUPPORTED] =
{
  // Simple Profile Service
  {
    { ATT_BT_UUID_SIZE, primaryServiceUUID },      /* type */
    GATT_PERMIT_READ,                              /* permissions */
    0,                                             /* handle */
    (uint8 *)&simpleProfileService                 /* pValue */
  },

  // Characteristic Declaration:GATT_PROP_READ | GATT_PROP_WRITE | GATT_PROP_WRITE_NO_RSP | GATT_PROP_NOTIFY
  {
    { ATT_BT_UUID_SIZE, characterUUID },
    GATT_PERMIT_READ,
    0,
    &simpleProfileCharProps
  },

  // Characteristic Value 1
  {
    { ATT_UUID_SIZE, simpleProfileCharUUID },
    GATT_PERMIT_READ | GATT_PERMIT_WRITE,
    0,
    &simpleProfileChar
  },

  //Characteristic configuration
  {
    { ATT_BT_UUID_SIZE, clientCharCfgUUID },
    GATT_PERMIT_READ | GATT_PERMIT_WRITE,
    0,
    (uint8 *)&simpleProfileCharConfig
  },

  // Characteristic User Description
  {
    { ATT_BT_UUID_SIZE, charUserDescUUID },
    GATT_PERMIT_READ,
    0,
    simpleProfileCharUserDesp
  },

};

3.修改广播数据adverData[]，打开simple_peripheral.c

// Advertisement data (max size = 31 bytes, though this is
// best kept short to conserve power while advertising)
static uint8_t advertData[] =
{
  // Flags: this field sets the device to use general discoverable
  // mode (advertises indefinitely) instead of general
  // discoverable mode (advertise for 30 seconds at a time)
  0x02,   // length of this data
  GAP_ADTYPE_FLAGS,
  DEFAULT_DISCOVERABLE_MODE | GAP_ADTYPE_FLAGS_BREDR_NOT_SUPPORTED,

  // service UUID, to notify central devices what services are included
  // in this peripheral
  0x11,                                           // Length of this data
  GAP_ADTYPE_128BIT_COMPLETE,                     // Complete list of 128-bit UUIDs
  MIDI_PROFILE_SERV_UUID                          // MIDI Service UUID
};
