DA145XX协议芯片支持配置HOGP功能。即模拟蓝牙键鼠之类的设备，实现和手机绑定后，靠近设备手机自动回连设备的功能。实现HOGP功能需要对默认SDK做特殊配置，具体流程如下：

1、配置宏定义

da1458x_config_basic.h文件：

/****************************************************************************************************************/
/* Enables the BLE security functionality in TASK_APP. If not defined BLE security related code is compiled out.*/
/****************************************************************************************************************/
#define CFG_APP_SECURITY

user_config.h文件：
(1)、对SMP参数的配置，具体根据项目需求配置做配置
(2)、配置广播内容，需要特定的广播内容，才能正常在手机蓝牙系统用界面实现设备信息

};

2、实现SMP相关自定义函数

user_app_init里的两段代码，第一段使IOS客户端也实现重连功能，第二段会使BLE连接GATT通讯必须要先完成SMP配对后才可进行

//处理配对请求
void user_app_on_pairing_request(uint8_t conidx, struct gapc_bond_req_ind const *param)
{if(System_Sta.hogp_switch){app_easy_security_send_pairing_rsp(conidx, param);}else{app_easy_security_reject_encryption(conidx);}
}//蓝牙安全认证配对成功回调
void user_app_on_pairing_succeeded(uint8_t conidx)
{if (app_sec_env[conidx].auth & GAP_AUTH_BOND){app_easy_security_bdb_add_entry(&app_sec_env[0]);	//添加绑定信息}
}//交换TK回调
void user_app_on_tk_exch(uint8_t conidx,struct gapc_bond_req_ind const * param)
{app_easy_security_accept_encryption(conidx);
}//收到安全连接检查请求
//HOGP回连后，会触发该回调
void user_app_on_encrypt_req_ind(uint8_t conidx,struct gapc_encrypt_req_ind const *param)
{const struct app_sec_bond_data_env_tag *pbd = NULL;pbd = app_easy_security_bdb_search_entry(SEARCH_BY_EDIV_TYPE, (void *) &param->ediv, 2);// If peer has been found in DBif(pbd){// Store device bond data to security environmentapp_sec_env[conidx] = *pbd;// Accept encryptionapp_easy_security_accept_encryption(conidx);}// If peer has not been found in DBelse{// Reject encryption, disconnectapp_easy_security_reject_encryption(conidx);}
}//处理APP事件回调
void user_catch_rest_hndl(ke_msg_id_t const msgid,void const *param,ke_task_id_t const dest_id,ke_task_id_t const src_id)
{switch(msgid){//添加：26xx HID事件
#if BLE_HID_DEVICEcase HOGPD_REPORT_UPD_RSP:case HOGPD_PROTO_MODE_REQ_IND:case HOGPD_NTF_CFG_IND:case HOGPD_CTNL_PT_IND:case HOGPD_REPORT_REQ_IND:{app_hogpd_process_handler(msgid, param, dest_id, src_id);break;}
#endif // BLE_HID_DEVICEdefault:break;}
}//APP初始化
void user_app_init(void)
{
//额外添加以下代码：#if (BLE_HID_DEVICE)app_set_prf_srv_perm(TASK_ID_DISS, SRV_PERM_UNAUTH);app_set_prf_srv_perm(TASK_ID_BASS, SRV_PERM_UNAUTH);app_set_prf_srv_perm(TASK_ID_HOGPD, SRV_PERM_UNAUTH);
#endif#if (BLE_APP_SEC)// Set service security requirementsapp_set_prf_srv_perm(TASK_ID_CUSTS1, SRV_PERM_UNAUTH);// Fetch bond data from the external memoryapp_set_prf_srv_perm(TASK_ID_GATT_CLIENT, SRV_PERM_UNAUTH);app_easy_security_bdb_init();
#endif // (BLE_APP_SEC)	
}

3、添加相关的库文件到项目中

app_security.c
app_security_task.c
app_easy_security.c
app_bond_db.c
这些文件在sdk\app_modules\src目录下引入

hogpd.c
hogpd_task.c
这些文件在sdk\ble_stack\profiles\hogp目录下引入

4、实现部分HOGP相关文件，配置HOGP相关的参数信息
具体可以参考github上官方的HOGP工程示例
https://github.com/dialog-semiconductor/BLE_SDK6_examples
项目下的示例工程：
interfaces/HID-Gamepad-Digitizer
具体要实现以下文件，可根据自身的业务逻辑进行修改：

app_hogpd_defs.h
该文件无需修改，直接使用官方HOGP示例工程内的文件即可

至此SDK已经具备实现HOGP功能的相关配置。

5、解决6.20以上版本SDKHOGP功能编译错误
使用ARM compiler6编译器，工程默认开启Link-Time Optimization编译后，会导致hogpd_task..c内部的函数编译报错：
Error: L6137E: Symbol gattc_read_req_ind_handler was not preserved by the LTO codegen but is needed by the image.
应该是编译器将该函数优化掉了，主要是这几个函数在SDK的其它地方被配置成了ROM调用，这里实际是这几个函数和那边重名了。要解决这个文件，可以将函数名自行做修改（加了一个my_的前缀），防止其被优化掉：

const struct ke_msg_handler hogpd_default_state[] =
{{ HOGPD_ENABLE_REQ,              (ke_msg_func_t) hogpd_enable_req_handler },{ HOGPD_REPORT_UPD_REQ,          (ke_msg_func_t) hogpd_report_upd_req_handler },{ HOGPD_REPORT_CFM,              (ke_msg_func_t) hogpd_report_cfm_handler },{ HOGPD_PROTO_MODE_CFM,          (ke_msg_func_t) hogpd_proto_mode_cfm_handler },{ GATTC_ATT_INFO_REQ_IND,        (ke_msg_func_t) my_gattc_att_info_req_ind_handler },{ GATTC_WRITE_REQ_IND,           (ke_msg_func_t) my_gattc_write_req_ind_handler },{ GATTC_READ_REQ_IND,            (ke_msg_func_t) my_gattc_read_req_ind_handler },{ GATTC_CMP_EVT,                 (ke_msg_func_t) my_gattc_cmp_evt_handler },
};

注意函数的定义处也要做对应修改。修改后，编译即可正常通过。
