【BLE】TLSR8258开发记录之5--SDK添加自定义服务

本文主要是介绍【BLE】TLSR8258开发记录之5--SDK添加自定义服务，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1、说明

在SDK V3.4 BLE sample中添加自定义服务，前期使用昇润APP，故需要符合他的server UUID。
实现打印功能需要先实现模拟串口的添加。服务说明

2、操作

A.在gatt_uuid.h中，添加定义服务定义

//MG add
#define SERVICE_UUID_MG_TMHR                                      0x1000//MG add
#define CHARACTERISTIC_UUID_MG_TMHR_RX                            0x1001
#define CHARACTERISTIC_UUID_MG_TMHR_TX                            0x1002

B.在app_config.h中，在ATT Handle define添加枚举定义

    //MG addTMHR /**********************************************************************************************/MG_TMHR_PS_H,MG_INCLUDE_H,                            MG_TMHR_INPUT_CD_H,MG_TMHR_INPUT_DP_H,MG_TMHR_OUTPUT_CD_H,MG_TMHR_OUTPUT_DP_H,MG_TMHR_INPUT_CCB_H,

C.在app_att.c中添加UUID定义

 MG TMHR /
static const u16 MG_TMHR_Service_UUID     = SERVICE_UUID_MG_TMHR;
static const u16 MG_TMHR_RX_CharUUID      = CHARACTERISTIC_UUID_MG_TMHR_RX;
static const u16 MG_TMHR_TX_CharUUID      = CHARACTERISTIC_UUID_MG_TMHR_TX;

添加数据缓冲区（输入输出）

//MG add
static u8 MG_TMHR_In[2];
static u8 MG_TMHR_InCCC[2];
static u8 MG_TMHR_Out[2];

添加特征值定义

//MG add
static const u8 MG_TMHR_CharVal_RX[5] = {CHAR_PROP_READ | CHAR_PROP_WRITE_WITHOUT_RSP | CHAR_PROP_NOTIFY,U16_LO(MG_TMHR_INPUT_DP_H),U16_HI(MG_TMHR_INPUT_DP_H),U16_LO(CHARACTERISTIC_UUID_MG_TMHR_RX),U16_HI(CHARACTERISTIC_UUID_MG_TMHR_RX)
};
static const u8 MG_TMHR_CharVal_TX[5] = {CHAR_PROP_READ | CHAR_PROP_NOTIFY,U16_LO(MG_TMHR_OUTPUT_DP_H),U16_HI(MG_TMHR_OUTPUT_DP_H),U16_LO(CHARACTERISTIC_UUID_MG_TMHR_TX),U16_HI(CHARACTERISTIC_UUID_MG_TMHR_TX)
};

添加自定义include服务

static const u16 MG_include[3] = {MG_TMHR_PS_H,MG_TMHR_INPUT_CCB_H,SERVICE_UUID_MG_TMHR};

在my_Attributes添加属性，其中“MG_TMHR_Write_CB”为写回调函数，即APP下发数据过来后，从机接收到数据后会进入该回调函数
以下代码添加的位置须与ATT Handle define中的"MG_TMHRxx"枚举位置相对应

//    // MG TMHR ///TMHR data service{6,ATT_PERMISSIONS_READ,2,2,(u8*)(&my_primaryServiceUUID), (u8*)(&MG_TMHR_Service_UUID),0},//   include MG service{0,ATT_PERMISSIONS_READ,2,sizeof(MG_include),(u8*)(&hidIncludeUUID),     (u8*)(MG_include), 0},//data RX{0,ATT_PERMISSIONS_READ,2,sizeof(MG_TMHR_CharVal_RX),(u8*)(&my_characterUUID), (u8*)(MG_TMHR_CharVal_RX), 0},    //prop{0,ATT_PERMISSIONS_RDWR,2,2,(u8*)(&MG_TMHR_RX_CharUUID),     (u8*)(MG_TMHR_Out), &MG_TMHR_Write_CB},    //value//data TX{0,ATT_PERMISSIONS_READ,2,sizeof(MG_TMHR_CharVal_TX),(u8*)(&my_characterUUID), (u8*)(MG_TMHR_CharVal_TX), 0},    //prop{0,ATT_PERMISSIONS_READ,2, 2,(u8*)(&MG_TMHR_TX_CharUUID),     (u8*)(MG_TMHR_In), 0},    //value{0,ATT_PERMISSIONS_RDWR,2,sizeof(MG_TMHR_InCCC),(u8*)(&clientCharacterCfgUUID),     (u8*)(MG_TMHR_InCCC), 0}

回调函数定义如下：（测试用）

//写回调函数
//static unsigned char led_status= 0;
int MG_TMHR_Write_CB(void *p)
{rf_packet_att_data_t *pw = (rf_packet_att_data_t*)p;int len = pw->l2cap - 3;int i=0;//打印数据for(i=0; i<len; i++){printf("Data[%d] is: %d \r\n",i,pw->dat[i]);}//io翻转//gpio_toggle(GPIO_PD2);//回复数据bls_att_pushNotifyData(MG_TMHR_OUTPUT_DP_H,&pw->dat,len);return 1;
}
