CC2650 之UUID配置

来源：互联网发布：s3世界总决赛faker数据编辑：程序博客网时间：2024/06/11 04:03

CC2650与CC2541的配置是相似的，先不看操作系统的对任务的调度，方便大家理解2650的工作流程，首先是CC2650的初始化，初始化的流程在simpleBLEPreipheral.c中。执行的流程是在main.c中对参数进行配置，然后开始调用BIOS_start();开始跑系统，基本参数配置完成开始进行广播，

void SimpleBLEPeripheral_createTask(void)
{
Task_Params taskParams;

// Configure task
Task_Params_init(&taskParams);
taskParams.stack = sbpTaskStack;
taskParams.stackSize = SBP_TASK_STACK_SIZE;
taskParams.priority = SBP_TASK_PRIORITY;

Task_construct(&sbpTask, SimpleBLEPeripheral_taskFxn, &taskParams, NULL);
} 通过这个函数对SimpleBLEPeripheral_taskFxn进行注册任务，

任务注册完后就开始执行SimpleBLEPeripheral_taskFxn函数，在这个函数中先执行SimpleBLEPeripheral_init();

static void SimpleBLEPeripheral_init(void)
{
// ******************************************************************
// N0 STACK API CALLS CAN OCCUR BEFORE THIS CALL TO ICall_registerApp

// Register the current thread as an ICall dispatcher application

}通过这个函数对设备进行配置，这个函数真的很重要，一定要弄懂。

然后就是static void SimpleBLEPeripheral_taskFxn(UArg a0, UArg a1)函数

通过一个for循环对任务进行查询，

{
// Initialize application
SimpleBLEPeripheral_init();

// Application main loop
for (;;)
{
// Waits for a signal to the semaphore associated with the calling thread.
// Note that the semaphore associated with a thread is signaled when a
// message is queued to the message receive queue of the thread or when
// ICall_signal() function is called onto the semaphore.
ICall_Errno errno = ICall_wait(ICALL_TIMEOUT_FOREVER);

if (errno == ICALL_ERRNO_SUCCESS)
{
ICall_EntityID dest;
ICall_ServiceEnum src;
ICall_HciExtEvt *pMsg = NULL;

if (ICall_fetchServiceMsg(&src, &dest,
(void **)&pMsg) == ICALL_ERRNO_SUCCESS)
{
uint8 safeToDealloc = TRUE;

if ((src == ICALL_SERVICE_CLASS_BLE) && (dest == selfEntity))
{
ICall_Event *pEvt = (ICall_Event *)pMsg;

// Check for BLE stack events first
if (pEvt->signature == 0xffff)
{
if (pEvt->event_flag & SBP_CONN_EVT_END_EVT)
{
// Try to retransmit pending ATT Response (if any)
SimpleBLEPeripheral_sendAttRsp();
}
}
else
{
// Process inter-task message
safeToDealloc = SimpleBLEPeripheral_processStackMsg((ICall_Hdr *)pMsg);
}
}

if (pMsg && safeToDealloc)
{
ICall_freeMsg(pMsg);
}
}

// If RTOS queue is not empty, process app message.
while (!Queue_empty(appMsgQueue))
{
sbpEvt_t *pMsg = (sbpEvt_t *)Util_dequeueMsg(appMsgQueue);
if (pMsg)
{
// Process message.
SimpleBLEPeripheral_processAppMsg(pMsg);

// Free the space from the message.
ICall_free(pMsg);
}
}
}
{
// Initialize application
SimpleBLEPeripheral_init();

// Application main loop
for (;;)
{
// Waits for a signal to the semaphore associated with the calling thread.
// Note that the semaphore associated with a thread is signaled when a
// message is queued to the message receive queue of the thread or when
// ICall_signal() function is called onto the semaphore.
ICall_Errno errno = ICall_wait(ICALL_TIMEOUT_FOREVER);

if (errno == ICALL_ERRNO_SUCCESS)
{
ICall_EntityID dest;
ICall_ServiceEnum src;
ICall_HciExtEvt *pMsg = NULL;

if (ICall_fetchServiceMsg(&src, &dest,
(void **)&pMsg) == ICALL_ERRNO_SUCCESS)
{
uint8 safeToDealloc = TRUE;

if ((src == ICALL_SERVICE_CLASS_BLE) && (dest == selfEntity))
{
ICall_Event *pEvt = (ICall_Event *)pMsg;

// Check for BLE stack events first
if (pEvt->signature == 0xffff)
{
if (pEvt->event_flag & SBP_CONN_EVT_END_EVT)
{
// Try to retransmit pending ATT Response (if any)
SimpleBLEPeripheral_sendAttRsp();
}
}
else
{
// Process inter-task message
safeToDealloc = SimpleBLEPeripheral_processStackMsg((ICall_Hdr *)pMsg);
}
}

if (pMsg && safeToDealloc)
{
ICall_freeMsg(pMsg);
}
}

// If RTOS queue is not empty, process app message.
while (!Queue_empty(appMsgQueue))
{
sbpEvt_t *pMsg = (sbpEvt_t *)Util_dequeueMsg(appMsgQueue);
if (pMsg)
{
// Process message.
SimpleBLEPeripheral_processAppMsg(pMsg);

// Free the space from the message.
ICall_free(pMsg);
}
}
}

然后就是在simpleGATTprofile.c和simpleGATTprofile.h中对UUID进行设置，通信的读写限制，数据大小等。

在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 1 Declaration
{
{ ATT_BT_UUID_SIZE, characterUUID },
GATT_PERMIT_READ,
0,
&simpleProfileChar1Props
},

// Characteristic Value 1
{
{ ATT_BT_UUID_SIZE, simpleProfilechar1UUID },
GATT_PERMIT_READ | GATT_PERMIT_WRITE,
0,
&simpleProfileChar1
},

// Characteristic 1 User Description
{
{ ATT_BT_UUID_SIZE, charUserDescUUID },
GATT_PERMIT_READ,
0,
simpleProfileChar1UserDesp
},

// Characteristic 2 Declaration
{
{ ATT_BT_UUID_SIZE, characterUUID },
GATT_PERMIT_READ,
0,
&simpleProfileChar2Props
},

// Characteristic Value 2
{
{ ATT_BT_UUID_SIZE, simpleProfilechar2UUID },

GATT_PERMIT_READ | GATT_PERMIT_WRITE,
0,
&simpleProfileChar2
},

// Characteristic 2 User Description
{
{ ATT_BT_UUID_SIZE, charUserDescUUID },
GATT_PERMIT_READ,
0,
simpleProfileChar2UserDesp
},

// Characteristic 3 Declaration
{
{ ATT_BT_UUID_SIZE, characterUUID },
GATT_PERMIT_READ,
0,
&simpleProfileChar3Props
},

// Characteristic Value 3
{
{ ATT_BT_UUID_SIZE, simpleProfilechar3UUID },
GATT_PERMIT_READ | GATT_PERMIT_WRITE,
0,
&simpleProfileChar3
},

// Characteristic 3 User Description
{
{ ATT_BT_UUID_SIZE, charUserDescUUID },
GATT_PERMIT_READ,
0,
simpleProfileChar3UserDesp
},

// Characteristic 4 Declaration
{
{ ATT_BT_UUID_SIZE, characterUUID },
GATT_PERMIT_READ,
0,
&simpleProfileChar4Props
},

// Characteristic Value 4
{
{ ATT_BT_UUID_SIZE, simpleProfilechar4UUID },
GATT_PERMIT_READ | GATT_PERMIT_WRITE,
0,
&simpleProfileChar4
},

// Characteristic 4 configuration
{
{ ATT_BT_UUID_SIZE, clientCharCfgUUID },
GATT_PERMIT_READ ,
0,
(uint8 *)&simpleProfileChar4Config
},

// Characteristic 4 User Description
{
{ ATT_BT_UUID_SIZE, charUserDescUUID },
GATT_PERMIT_READ,
0,
simpleProfileChar4UserDesp
},

// Characteristic 5 Declaration
{
{ ATT_BT_UUID_SIZE, characterUUID },
GATT_PERMIT_READ,
0,
&simpleProfileChar5Props
},

// Characteristic Value 5
{
{ ATT_BT_UUID_SIZE, simpleProfilechar5UUID },
GATT_PERMIT_READ | GATT_PERMIT_WRITE,
0,
simpleProfileChar5
},

// Characteristic 5 User Description
{
{ ATT_BT_UUID_SIZE, charUserDescUUID },
GATT_PERMIT_READ,
0,
simpleProfileChar5UserDesp
},
};

对UUID读写权限进行设置，和数据的大小。

通过static bStatus_t simpleProfile_ReadAttrCB(uint16_t connHandle,
gattAttribute_t *pAttr,
uint8_t *pValue, uint16_t *pLen,
uint16_t offset, uint16_t maxLen,
uint8_t method)
{
bStatus_t status = SUCCESS;

// If attribute permissions require authorization to read, return error
if ( gattPermitAuthorRead( pAttr->permissions ) )
{
// Insufficient authorization
return ( ATT_ERR_INSUFFICIENT_AUTHOR );
}

// Make sure it's not a blob operation (no attributes in the profile are long)
if ( offset > 0 )
{
return ( ATT_ERR_ATTR_NOT_LONG );
}

if ( pAttr->type.len == ATT_BT_UUID_SIZE )
{
// 16-bit UUID
uint16 uuid = BUILD_UINT16( pAttr->type.uuid[0], pAttr->type.uuid[1]);
switch ( uuid )
{
// No need for "GATT_SERVICE_UUID" or "GATT_CLIENT_CHAR_CFG_UUID" cases;
// gattserverapp handles those reads

// characteristics 1 and 2 have read permissions
// characteritisc 3 does not have read permissions; therefore it is not
// included here
// characteristic 4 does not have read permissions, but because it
// can be sent as a notification, it is included here
case SIMPLEPROFILE_CHAR1_UUID:
case SIMPLEPROFILE_CHAR2_UUID:
case SIMPLEPROFILE_CHAR3_UUID:
case SIMPLEPROFILE_CHAR4_UUID:
*pLen = 1;
pValue[0] = *pAttr->pValue;
break;

case SIMPLEPROFILE_CHAR5_UUID:
*pLen = SIMPLEPROFILE_CHAR5_LEN;
VOID memcpy( pValue, pAttr->pValue, SIMPLEPROFILE_CHAR5_LEN );
break;

default:
// Should never get here! (characteristics 3 and 4 do not have read permissions)
*pLen = 0;
status = ATT_ERR_ATTR_NOT_FOUND;
break;
}
}
else
{
// 128-bit UUID
*pLen = 0;
status = ATT_ERR_INVALID_HANDLE;
}

return ( status );
}这个函数进行数据的读取和处理，我们也可以通过这结构去添加自己的属性函数
