nRF52832 — 微信移植（官方例子移植到SDK12.2.0）

参考网址：http://blog.csdn.net/a369000753/article/details/51262261

1.目的

      把官方的代码移植到sdk12.2.0版本

2.分析

    由于官方的版本过低，移植到高版本

3.平台：

协议栈版本：SDK12.2.0

编译软件：keil 5.12

硬件平台：nrf52832最小系统

例子：SDK 12.2.0\examples\ble_peripheral\ble_app_uart\pca10028\s110\arm4

4.步骤

   需要准备的资料，

    一个是微信官方代码，一个是nrfSDK

   微信下载地址：http://iot.weixin.qq.com/wiki/new/index.html?page=6-1  

首先，添加几个文件夹：

products；

wechatapp；

wechatservices；

文件夹的内容分别实在微信的对应名字的文件copy出来的，把他们加到SDKnRF5_SDK_12.2.0_f012efa\examples\ble_peripheral\ble_app_uart_git\pca10040\s132\arm4工程里面，并添加对应的路径；

    文件夹对应的内容为：

在main.c里面添加：

static  ble_wechat_t                                      m_ble_wechat;  //¶¨Òå΢ÐÅ·þÎñ  
uint8_t                                                               m_addl_adv_manuf_data[BLE_GAP_ADDR_LEN];  

ble_evt_dispatch()函数变为如下：

/**@brief Function for dispatching a S110 SoftDevice event to all modules with a S110 SoftDevice  
 *        event handler. 
 * 
 * @details This function is called from the S110 SoftDevice event interrupt handler after a S110  
 *          SoftDevice event has been received. 
 * 
 * @param[in] p_ble_evt  S110 SoftDevice event. 
 */static void ble_evt_dispatch(ble_evt_t * p_ble_evt)  
{  
    ble_conn_params_on_ble_evt(p_ble_evt);  
    //ble_nus_on_ble_evt(&m_nus, p_ble_evt);  
    on_ble_evt(p_ble_evt);  
    ble_advertising_on_ble_evt(p_ble_evt);  
    bsp_btn_ble_on_ble_evt(p_ble_evt);  
    ble_wechat_on_ble_evt(&m_ble_wechat, p_ble_evt, m_mpbledemo2_handler);  //Ìí¼ÓÍþÐÅ·þÎñʼþ  
      m_mpbledemo2_handler->m_data_on_ble_evt_func(&m_ble_wechat,p_ble_evt);  //  

services-init()函数变为：

/**@brief Function for initializing services that will be used by the application. 
 */  
static void services_init(void)  
{  
    uint32_t       err_code;  
//    ble_nus_init_t nus_init;  
//      
//    memset(&nus_init, 0, sizeof(nus_init));  
  
//    nus_init.data_handler = nus_data_handler;  
//      
//    err_code = ble_nus_init(&m_nus, &nus_init);  
//    APP_ERROR_CHECK(err_code);      
  
  
        err_code = ble_wechat_add_service(&m_ble_wechat);  
        APP_ERROR_CHECK(err_code);  
        err_code = ble_wechat_add_characteristics(&m_ble_wechat);  
        APP_ERROR_CHECK(err_code);  
} 

advertising_init()函数变为：

**@brief Function for initializing the Advertising functionality.  
 */  
static void advertising_init(void)  
{  
    uint32_t      err_code;  
    ble_advdata_t advdata;  
    //ble_advdata_t scanrsp;  
      
//   uint32_t      err_code;  
    //ble_advdata_t advdata;  
        /**< LE General Discoverable Mode, BR/EDR not supported. */  
    uint8_t       flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;  
  
    ble_uuid_t adv_uuids[] =  
    {  
        {BLE_UUID_WECHAT_SERVICE,         BLE_UUID_TYPE_BLE}  
    };  
        memset(&advdata, 0, sizeof(advdata));  
          
    advdata.name_type               = BLE_ADVDATA_FULL_NAME;  
    advdata.include_appearance      = false;      
    advdata.flags                     = flags;  
    advdata.uuids_complete.uuid_cnt = sizeof(adv_uuids) / sizeof(adv_uuids[0]);  
    advdata.uuids_complete.p_uuids  = adv_uuids;          
          
        ble_advdata_manuf_data_t        manuf_data;  
    manuf_data.company_identifier = COMPANY_IDENTIFIER;  
    manuf_data.data.size          = sizeof(m_addl_adv_manuf_data);  
    manuf_data.data.p_data        = m_addl_adv_manuf_data;  
    advdata.p_manuf_specific_data = &manuf_data;  
          
    err_code = ble_advdata_set(&advdata, NULL);  
    APP_ERROR_CHECK(err_code);  
            // Initialize advertising parameters (used when starting advertising)  
    //memset(&m_adv_params, 0, sizeof(m_adv_params));  
  
  
    // Build and set advertising data  
    // Build advertising data struct to pass into @ref ble_advertising_init.  
//    memset(&advdata, 0, sizeof(advdata));  
//    advdata.name_type          = BLE_ADVDATA_FULL_NAME;  
//    advdata.include_appearance = false;  
//    advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;  
//    memset(&scanrsp, 0, sizeof(scanrsp));  
//    scanrsp.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);  
//    scanrsp.uuids_complete.p_uuids  = m_adv_uuids;  
  
    ble_adv_modes_config_t options = {0};  
    options.ble_adv_fast_enabled  = true;  
    options.ble_adv_fast_interval = APP_ADV_INTERVAL;  
    options.ble_adv_fast_timeout  = APP_ADV_TIMEOUT_IN_SECONDS;  
  
    err_code = ble_advertising_init(&advdata, NULL, &options, on_adv_evt, NULL);  
    APP_ERROR_CHECK(err_code);  
}  

添加如下代码：

/**************************************************************************** 
?    ?: get_mac_addr() 
?    ?: »ñµÃÀ¶ÑÀµÄmacµØÖ· 
????: void 
????: ? 
****************************************************************************/  
void get_mac_addr(uint8_t *p_mac_addr)  
{  
        uint32_t error_code;  
        ble_gap_addr_t *p_mac_addr_t = (ble_gap_addr_t*)malloc(sizeof(ble_gap_addr_t));  
        error_code = sd_ble_gap_address_get(p_mac_addr_t);  
        APP_ERROR_CHECK(error_code);  
#ifdef CATCH_LOG  
        printf("\r\n error:%d",error_code);  
        printf("\r\n get mac addr");  
#endif  
        uint8_t *d = p_mac_addr_t->addr;     for ( uint8_t i = 6; i >0;)  
    {     
        i--;  
        p_mac_addr[5-i]= d[i];  
        #ifdef CATCH_LOG  
        printf ( ":%02x", d[i]);  
        #endif  
    }  
    #ifdef CATCH_LOG  
        putchar ( '\n' );  
    #endif  
    free(p_mac_addr_t);  
    p_mac_addr_t = NULL;  
}  

/****************************************************************************

****************************************************************************/  
void    data_handler_init(data_handler** p_data_handler, uint8_t product_type)  
{  
    if (*p_data_handler == NULL)   
        {  
            *p_data_handler = get_handler_by_type(product_type);  
        }  
}  

/****************************************************************************

****************************************************************************/  
//function for register all products  
 void register_all_products(void) {  
        REGISTER(mpbledemo2);  
}  

主函数如下：

/**@brief Application main function. 
 */  
int main(void)  
{  
    uint32_t err_code;  
    bool erase_bonds;  
    uint8_t  start_string[] = START_STRING;  
      
    // Initialize.  
    APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);  
    uart_init();  
    buttons_leds_init(&erase_bonds);  
    ble_stack_init();  
    //微信处理    
      get_mac_addr(m_addl_adv_manuf_data);  
    register_all_products();  
      data_handler_init(&m_mpbledemo2_handler,  PRODUCT_TYPE_MPBLEDEMO2);  
      
    gap_params_init();  
    services_init();  
    advertising_init();  
    conn_params_init();  
      
    printf("%s",start_string);  
    //  
      
    err_code = ble_advertising_start(BLE_ADV_MODE_FAST);  
    APP_ERROR_CHECK(err_code);  
  
    // Enter main loop.  
    for (;;)  
    {  
        power_manage();  
              m_mpbledemo2_handler->m_data_main_process_func(&m_ble_wechat);  
    }  
}  

OK，移植完毕。。编译如下：（解决编译错误）

1、在main.c添加ble_wechat_service.h和mpbledemo.h头文件；

2、在main.c添加extern data_handler * m_mpbledemo2_handler;

3、屏蔽掉ble_stack_handler.h和consource.h；

4、修改ble_gap_address_get为ble_gap_addr_get；

至此，编译通过~按照上述步骤，实测IOS LightBlue可以收到数据~

下一篇调试，与AirSyncDebugger收发数据~~~
