1. 准备

1.1 SDK文件

nRF5_SDK_15.2.0_9412b96.zip 和 (nrf5SDKforMeshv310src.zip，官方下载链接

1.2 集成开发环境工具

SEGGER Embedded Studio 4.1.2,下载链接

1.3 工具

J-link和天猫精灵

2. 平台设置

登录并注册AliGenie 的IOT接入平台,网址.点击控制台，选择添加新产品，设置产品信息，随便选一个品牌吧。

3. 协议对接

这个是天猫精灵官方提供的蓝牙mesh软件基础规范,网址
我基于nrf5SDKforMeshv310src\examples\light_switch\server例子，修改了几个地方，一个是三元组信息,设备地址,广播包,Confirmation匹配,和绑定Appkey。
建议将prov_provisionee.c将PROV_DEBUG_MODE置1，不仅可以让我们理解配网的一个完成过程（包括公钥交换，Confirmation确认等），也可以方便查找配网过程中的问题

3.1 三元组信息

三元组信息包括ProductID,DeviceSecret,MAC地址。点击,进入控制台->点击相对应的产品->3.设备调试->点击查看，就可以得到三元组信息了,随便选择一组三元组信息。根据三元组信息计算AuthValue:

uint8_t mIAuthValue[32] = {0};
void sha256test()
{
     sha256_context_t sha256_ctx;
    uint32_t err_code = NRF_SUCCESS;

    err_code = sha256_init(&sha256_ctx);
    if (err_code != NRF_SUCCESS)
    {
         __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Error in sha256_init (%d)", err_code);
    }
    //00002b57:ProductId的16进制
    //f8a76392b60f:MAC地址
    //8ad28fbcdfcad149d1f89d8a3a01fab7:DeviceSecret
    sha256_update(&sha256_ctx, "00002b57,f8a76392b60f,8ad28fbcdfcad149d1f89d8a3a01fab7", strlen("00002b57,f8a76392b60f,8ad28fbcdfcad149d1f89d8a3a01fab7")); 
    sha256_final(&sha256_ctx, mIAuthValue,false);
     __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "sha256test\n");
}

3.2 修改设备蓝牙地址

设备蓝牙地址也就是上图中的MAC地址，注意地址数据的大小端模式,可以使用蓝牙软件（比如nRF connect）看看地址是否准确。

main.c
static void initialize(void)
{
    __LOG_INIT(LOG_SRC_APP | LOG_SRC_ACCESS | LOG_SRC_BEARER | LOG_SRC_API |LOG_SRC_PROV, LOG_LEVEL_INFO, LOG_CALLBACK_DEFAULT);
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "----- BLE Mesh Light Switch Server Demo -----\n");

    ERROR_CHECK(app_timer_init());
    hal_leds_init();

#if BUTTON_BOARD
    ERROR_CHECK(hal_buttons_init(button_event_handler));
#endif

    ble_stack_init();
    ble_gap_addr_t my_addr;
    uint32_t error_code;
    static ble_gap_addr_t m_central_addr;
    uint8_t addr[6] = {0x0f,0xb6,0x92,0x63,0xa7,0xf8};//f8a76392b60f

    m_central_addr.addr_type     = BLE_GAP_ADDR_TYPE_RANDOM_STATIC;
    m_central_addr.addr[0] = (uint8_t)addr[0];
    m_central_addr.addr[1] = (uint8_t)(addr[1]);
    m_central_addr.addr[2] = (uint8_t)(addr[2]);
    m_central_addr.addr[3] = (uint8_t)(addr[3]);
    m_central_addr.addr[4] = (uint8_t)addr[4];
    m_central_addr.addr[5] = (uint8_t)(addr[5]); // 2MSB must be set 11
    sd_ble_gap_addr_set(&m_central_addr);

#if MESH_FEATURE_GATT_ENABLED
    gap_params_init();
    conn_params_init();
#endif
    mesh_init();
}

3.3 广播包

main.c
static void mesh_init(void)
{
    const uint8_t tianmao_uuid[16] ={
    0xA8,0x01,//公司ID
    0x71,//蓝牙广播版本号
    0x57,0x2b,0x00,0x00,//ProjectID
    0x0f,0xb6,0x92,0x63,0xa7,0xf8,//Mac地址
    0x02,//UUID版本号
    0x00,0x00};
    mesh_stack_init_params_t init_params =
    {
        .core.irq_priority       = NRF_MESH_IRQ_PRIORITY_LOWEST,
        .core.lfclksrc           = DEV_BOARD_LF_CLK_CFG,
        .core.p_uuid             = &tianmao_uuid[0],
        .models.models_init_cb   = models_init_cb,
        .models.config_server_cb = config_server_evt_cb
    };
    ERROR_CHECK(mesh_stack_init(&init_params, &m_device_provisioned));
}

3.4 Confirmation匹配

Confirmation在天猫精灵和Mesh设备进行双向认证，所以要修改两个地方，如下:
prov_utils.c:

extern uint8_t mIAuthValue[32];
void prov_utils_authentication_values_derive(const nrf_mesh_prov_ctx_t * p_ctx,
        uint8_t * p_confirmation_salt,
        uint8_t * p_confirmation,
        uint8_t * p_random)
{
    create_confirmation_salt(p_ctx, p_confirmation_salt);

    uint8_t confirmation_key[NRF_MESH_KEY_SIZE];

    /* ConfirmationKey = k1(ECDHSecret, ConfirmationSalt, "prck") */
    enc_k1(p_ctx->shared_secret,
           NRF_MESH_ECDH_SHARED_SECRET_SIZE,
           p_confirmation_salt,
           CONFIRMATION_KEY_INFO, CONFIRMATION_KEY_INFO_LENGTH,
           confirmation_key);
    rand_hw_rng_get(p_random, PROV_RANDOM_LEN);
    uint8_t random_and_auth[PROV_RANDOM_LEN + PROV_AUTH_LEN];
    memcpy(&random_and_auth[0], p_random, PROV_RANDOM_LEN);
    //memcpy(&random_and_auth[PROV_RANDOM_LEN], p_ctx->auth_value, PROV_AUTH_LEN);
    memcpy(&random_and_auth[PROV_RANDOM_LEN], mIAuthValue, PROV_AUTH_LEN);
    /* Confirmation value = AES-CMAC(ConfirmationKey, LocalRandom || AuthValue) */
    enc_aes_cmac(confirmation_key,
                 random_and_auth,
                 PROV_RANDOM_LEN + PROV_AUTH_LEN,
                 p_confirmation);
}

bool prov_utils_confirmation_check(const nrf_mesh_prov_ctx_t * p_ctx)
{
    uint8_t confirmation_key[NRF_MESH_KEY_SIZE];

    /* ConfirmationKey = k1(ECDHSecret, ConfirmationSalt, "prck") */
    enc_k1(p_ctx->shared_secret,
           NRF_MESH_ECDH_SHARED_SECRET_SIZE,
           p_ctx->confirmation_salt,
           CONFIRMATION_KEY_INFO, CONFIRMATION_KEY_INFO_LENGTH,
           confirmation_key);

    uint8_t random_and_auth[PROV_RANDOM_LEN + PROV_AUTH_LEN];
    memcpy(&random_and_auth[0], p_ctx->peer_random, PROV_RANDOM_LEN);
    //memcpy(&random_and_auth[PROV_RANDOM_LEN], p_ctx->auth_value, PROV_AUTH_LEN);
    memcpy(&random_and_auth[PROV_RANDOM_LEN], mIAuthValue, PROV_AUTH_LEN);

    /* Confirmation value = AES-CMAC(ConfirmationKey, LocalRandom || AuthValue) */
    uint8_t confirmation[PROV_CONFIRMATION_LEN];
    enc_aes_cmac(confirmation_key,
                 random_and_auth,
                 PROV_RANDOM_LEN + PROV_AUTH_LEN,
                 confirmation);

    return memcmp(confirmation, p_ctx->peer_confirmation, sizeof(confirmation)) == 0;
}

3.5 Appkey和地址绑定

配网完成之后，天猫精灵会直接下发三个Appkey（我测试三个Appkey都是一样）。配网完成之后我直接用这个Appkey绑定到health Model和Generic OnOff Server Model。

   void mI_bind_appkey(){
     uint32_t status =0;
     mesh_key_index_t appkey_index =0;
     access_model_handle_t model_handle =2;
     dsm_handle_t appkey_handle = dsm_appkey_index_to_appkey_handle(appkey_index);
     status = access_model_application_bind(model_handle, appkey_handle);
     if (status == NRF_SUCCESS)
     {
          __LOG(LOG_SRC_PROV, LOG_LEVEL_INFO, "bind appkey is ok\nn");
     }
}

给Generic OnOff Server Model设置组地址

void Add_subscription_address(uint16_t address){
     uint32_t status =0;
     access_model_handle_t model_handle =2;

     /* Check that the subscription address is valid before continuing: */
    nrf_mesh_address_type_t address_type = nrf_mesh_address_type_get(address);
    if ((address_type != NRF_MESH_ADDRESS_TYPE_GROUP) || (address == NRF_MESH_ALL_NODES_ADDR))
    {
        return;
    }

     /* Add the address to the DSM as a subscription address: */
    dsm_handle_t subscription_address_handle;
    status = dsm_address_subscription_add(address, &subscription_address_handle);
    if (status != NRF_SUCCESS){
        return;
    }

     /* Add the subscription to the model: */
    status = access_model_subscription_add(model_handle, subscription_address_handle);
    __LOG(LOG_SRC_PROV, LOG_LEVEL_INFO, "Provisionee: subscription_address_handle:%d,\n",subscription_address_handle);
    if (status != NRF_SUCCESS)
    {
        NRF_MESH_ASSERT(dsm_address_subscription_remove(subscription_address_handle) == NRF_SUCCESS);
    }
    else
    {
        __LOG(LOG_SRC_PROV, LOG_LEVEL_INFO, "main: subscription finish\n");
        access_flash_config_store();
    }
}

配网完成的回调:

static void provisioning_complete_cb(void)
{
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Successfully provisioned\n");

#if MESH_FEATURE_GATT_ENABLED
    /* Restores the application parameters after switching from the Provisioning
     * service to the Proxy  */
    gap_params_init();
    conn_params_init();
#endif
    dsm_local_unicast_address_t node_address;
    dsm_local_unicast_addresses_get(&node_address);
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Node Address: 0x%04x \n", node_address.address_start);
    mI_bind_appkey();
    Add_subscription_address(0xc001);
    hal_led_blink_stop();
    hal_led_mask_set(LEDS_MASK, LED_MASK_STATE_OFF);
    hal_led_blink_ms(LEDS_MASK, LED_BLINK_INTERVAL_MS, LED_BLINK_CNT_PROV);
    app_onoff_status_publish(&m_onoff_server_0);
}
